Abstract
The Global Polio Eradication Initiative, launched in 1988, is close to achieving its goal. In 2015, reported cases of wild poliovirus were limited to just two countries - Afghanistan and Pakistan. Africa has been polio-free for more than 18 months. Remaining barriers to global eradication include insecurity in areas such as Northwest Pakistan and Eastern and Southern Afghanistan, where polio cases continue to be reported. Hostility to vaccination is either based on extreme ideologies, such as in Pakistan, vaccination fatigue by parents whose children have received more than 15 doses, and misunderstandings about the vaccine's safety and effectiveness such as in Ukraine. A further challenge is continued circulation of vaccine-derived poliovirus in populations with low immunity, with 28 cases reported in 2015 in countries as diverse as Madagascar, Ukraine, Laos, and Myanmar. This paper summarizes the current epidemiology of wild and vaccine-derived poliovirus, and describes the remaining challenges to eradication and innovative approaches being taken to overcome them.

Abstract
BACKGROUND The high number of postgraduate global health courses, websites such as Global Health Gateway, annual conferences such as the Global Ideas Forum, and global health interest groups in all 20 Australian medical schools are indicators of increased interest among Australian doctors in working overseas. OBJECTIVE This article provides an overview of the health situation in low-income and middle-income countries, and summarises current approaches to improving the health of those living in countries with a developing economy. Opportunities for overseas assignments by generalist medical doctors in emergency and non-emergency settings are described, and appropriate pathways to prepare for such work are outlined. DISCUSSION The ideal training for overseas work is a Master or Diploma of Public Health, with a global health specialisation. These are available in 16 Australian and two New Zealand universities. Individual units can be taken as short courses, for example, in field epidemiology, maternal and child health, communicable diseases, nutrition, and health in complex emergencies.

Abstract
Laos is a low-income food-deficit country with pockets of high levels of wasting in the highland areas. We implemented a 3-year health/nutrition project in 12 villages in the highlands of Savannakhet province to reduce acute malnutrition in children. Volunteer nutrition teams in each village monitored child growth and promoted healthy feeding practices; a multisectoral district committee conducted monthly outreach to assess child growth, manage acute malnutrition and deliver primary health care services. We conducted a cross-sectional assessment before project activities began and at the end of the project. The baseline survey randomly sampled 60% of all households; the endline assessment aimed to survey all eligible registered participants. Anthropometric measures were taken from children aged 6-59 months; mothers with children aged <12 months were asked about infant feeding practices, antenatal and post-partum care; and child immunizations were recorded for children aged between 0-23 months. At baseline, 721 households were sampled, while the endline assessment surveyed between 82% and 100% of eligible participants in each age group. Acute malnutrition reduced from 12.4% (95% CI: 10.4- 14.3) to 6.1% (4.9-7.3). Unhealthy feeding practices declined: in 2008, 40.0% (34.7-45.3) of mothers breastfed their newborn within 2 hours of birth and 30.8% (25.7-35.8) threw the colostrum away; in 2011, these figures were 72% and 8% respectively. Maternal care and child immunisation coverage also improved. Improving the health environment and child feeding practices appears to have markedly reduced the level of wasting. Unsafe feeding practices were common but readily changed by the community-based nutrition teams.

Abstract
PURPOSE To determine whether multiple primary breast cancers have similar genetic profiles, specifically Oncotype Dx Recurrence Scores, and whether obtaining Oncotype Dx on each primary breast cancer affects chemotherapy recommendations. METHODS A database of patients with hormone receptor-positive, lymph node-negative, breast cancer was created for those tumors that were sent for Oncotype Dx testing from the University of Michigan Health System from 1/24/2005 to 2/25/2013. Retrospective chart review abstracted details of tumor location, histopathology, distance between tumors, Oncotype Dx results, and chemotherapy recommendations. RESULTS Six hundred and sixty-six patients for whom Oncotype Dx testing was sent were identified, with 22 patients having multiple breast tumor specimens sent. Of the 22 patients who had multiple samples sent for analysis, chemotherapy recommendations were changed in 6 of 22 patients (27%) based on significant differences in Oncotype Dx Recurrence Scores. Qualitatively, there seems to be a greater difference in genetic profile in tumors appearing simultaneously on different breasts when compared to multiple tumors on the same breast. There was no association between distance between tumors and difference in Oncotype Dx scores for tumors on the same breast. CONCLUSIONS Oncotype Dx testing on multiple primary breast cancers altered management in regards to chemotherapy recommendations and should be considered for multiple primary breast cancers.

Abstract
Men's decisions and behaviours influence the sexual, reproductive and maternal health of women and the health of their families, but men are rarely included in reproductive and maternal health care services. Men's attendance at antenatal care has the potential to prevent women from becoming infected with HIV during pregnancy and post-partum, when they are more vulnerable to infection and have a high risk of transmission to the infant. Greater involvement of men requires an understanding of social, cultural and organisational barriers in different contexts. In 2006, the Burnet Institute undertook fieldwork to inform a pilot project to encourage expectant fathers to attend antenatal care. A local Lao team conducted focus group discussions and interviews in Vientiane with expectant fathers, pregnant women, older women and health care providers. It was found that myths about the dangers of sex during pregnancy and women's decreased desire resulted in periods of sexual abstinence. Participants reported that unprotected extramarital sex was common but difficult for couples to discuss. Men lacked knowledge about sexually transmitted infections, including HIV. Men wanted information so they could better protect the health of their partners and babies during and after pregnancy, and reported being willing to attend antenatal care when invited. Our findings have useful implications for policy and implementation.

Abstract
QUESTION What is the point prevalence and 12-month prevalence of lower limb musculoskeletal pain in rural Tibet? Does this differ with gender or age? What factors that could contribute to lower limb musculoskeletal pain are commonly present? DESIGN Observational study using an investigator-administered questionnaire and observation walks through villages. PARTICIPANTS 499 people aged 15 years and over living in 19 rural villages of Shigatse Municipality, Tibet. RESULTS The point prevalence of lower limb musculoskeletal pain was 40% (95% CI 34 to 46) while the 12-month prevalence was 48% (95% CI 42 to 54). In particular, the point prevalence of knee pain was 25% (95% CI 20 to 30) and the 12-month prevalence was 29% (95% CI 23 to 35), which was significantly higher than at any other site in the lower limb. On average, being female was not associated with lower limb musculoskeletal pain either currently (OR 1.3, 95% CI 0.9 to 1.9) or over the previous 12 months (OR 1.2, 95% CI 0.9 to 1.8), whereas being older than 50 years was, both for current pain (OR 4.1, 95% CI 2.8 to 6.1) and pain over the previous 12 months (OR 4.0, 95% CI 2.7 to 6.0). Observation walks through the villages revealed people squatting for sustained periods, carrying heavy loads for long distances, wearing poor quality footwear, and with severe bowing of the legs but no obesity. CONCLUSION Lower limb musculoskeletal pain, particularly knee pain, is common in this rural Tibetan population. They live an extremely arduous life that appears to place considerable pressure on their knees.

Abstract
A partnership was formed between a mass youth organization, a national HIV coordinating committee, and an international agency, to implement an HIV capacity building project in the youth sector of Lao PDR. Involving the local community in situation analysis, planning and skills-building was a key focus of the project. District project working teams were trained in situation analysis, strategic planning, proposal development, and the implementation of HIV prevention activities. Young village volunteers were trained in participatory research, analysis, and behaviour change communication to promote HIV prevention. After 6 years, the partnership used qualitative methods to evaluate the local outcomes of the project. We found that district project working teams and young volunteers had improved skills in the areas in which they had been trained. Communities and local government workers had developed greater understanding of the HIV situation in their districts, and expressed a strong sense of ownership over their activity plans. Young people more readily acknowledged personal risk of HIV infection and were more comfortable talking about sexually transmitted infections. Although there were challenges to sustaining project activities in some areas, we found that our approach helped to engage youth and build their resilience to HIV in this country of low prevalence.

Abstract
METHODS Focus group discussions were conducted with a range of young men in Vientiane, Laos; interviews were conducted with male sex workers. A questionnaire survey was conducted with a purposive sample of 800 young men. RESULTS Most young men initiate sex at an early age and have multiple sex partners. Married men are more likely to pay for sex and most sex for money is negotiated in non-brothel settings. Despite high reported condom use for last intercourse with a casual partner, decisions on condom use are subjective. Many men have extramarital sex when their partner is pregnant and post partum. 18.5% of men report having had sex with another man; most of these men also report having sex with women. Moreover, more men report having had anal sex with a woman than with a man. CONCLUSIONS Although not a probability sample survey, this study of a broad range of young men in Vientiane reveals sexual behaviours that could lead to accelerated HIV transmission. Education should emphasise the need to use condoms in all sexual encounters outside the primary relationship. This needs special emphasis when the partner is pregnant or post partum. Advice on safe sex with other men needs to be integrated into all sexual health education for young men.

Abstract
The Lao People's Democratic Republic (Lao PDR) is classified by the World Bank as a low-income country under stress. Development partners have sought to utilize effective aid instruments to help countries classified in this way achieve the Millennium Development Goals; these aid instruments include sector-wide approaches (SWAps) that support decentralized district health systems and seek to avoid fragmentation and duplication. In Asia and the Pacific, only Bangladesh, Papua New Guinea and the Solomon Islands have adopted SWAps. Since 1991, a comprehensive primary health care programme in the remote Sayaboury Province of Lao PDR has focused on strengthening district health management, improving access to health facilities and responding to the most common causes of mortality and morbidity among women and children. Between 1996 and 2003, health-facility utilization tripled, and the proportion of households that have access to a facility increased to 92% compared with only 61% nationally. By 2003, infant and child mortality rates were less than one-third of the national rates. The maternal mortality ratio decreased by 50% despite comprehensive emergency obstetric care not being available in most district hospitals. These trends were achieved with an investment of approximately 4 million US dollars over 12 years (equivalent to US 1.00 US dollars per person per year). However, this project did not overcome weaknesses in some national disease-control programmes, especially the expanded programme on immunization, that require strong central management. In Lao PDR, which is not yet committed to using SWAps, tools developed in Sayaboury could help other district health offices assume greater planning responsibilities in the recently decentralized system. Development partners should balance their support for centrally managed disease-specific programmes with assistance to horizontally integrated primary health care at the district level.

Hepatitis E virus infection as a marker for contaminated community drinking water sources in Tibetan villages. Am J Trop Med Hyg 2006; 74:250-4.

Abstract
In April-May 2001, a study was conducted to determine the prevalence of antibodies against hepatitis E virus (HEV) among 426 persons 8-49 years of age randomly selected from two groups of rural villages in central Tibet. Group 1 villages were assessed in 1998 as having poor quality water sources; new water systems were then constructed prior to this study. Group 2 villages had higher quality water and were not designated as priority villages for new systems prior to the study. No participants tested positive for IgM; only IgG was detected in the analyzed samples. Overall, 31% of the participants had ever been infected with HEV (95% confidence interval [CI] = 26.7-35.7%). The rate was higher in men (36.6%) than women (26.3%) and highest in those 30-39 years of age (49.1%). The rate of past infection was higher in group 1; the risk ratio was 2.77 (95% CI = 1.98-3.88). This difference is most likely the result of the poor quality of the original water sources in these villages. In resource-poor countries, HEV may be a useful health indicator reflecting the degree of contamination in village water sources. This may be especially important in rural areas (such as Tibet) where maternal mortality ratios are high because HEV may be an important cause of deaths during pregnancy in disease-endemic areas.

Abstract
In a baseline assessment of 30 rural villages surrounding Shigatse City, Tibet, many people, especially women, identified low back pain as a serious health problem. Consequently, we aimed to establish the prevalence of such pain and to develop appropriate interventions. We did a cross-sectional study of the prevalence of low back pain and related functional disability using two-stage random cluster sampling. We included 499 adults aged at least 15 years from 19 villages. The point prevalence of low back pain was 34.1% (95% CI 27.9-40.3% [170 people]); the 12-month prevalence was 41.9% (35.5-48.3% [209 people]). 100 (20%) villagers had substantial functional disability associated with low back pain. Low back pain is likely to be an important and under recognised problem in rural societies like Tibet.

Abstract
BACKGROUND In January 1993, Nyamithuthu Camp in Malawi housed 64000 Mozambican refugees. Communicable diseases, primarily diarrhoea, pneumonia, malaria and measles, contribute to substantially higher mortality rates in refugee populations compared to similar non-displaced populations. METHOD A systematic sample of 402 households in one portion of the camp were surveyed for diarrhoeal risk factors, and then interviewed twice weekly for 4 months regarding new diarrhoea episodes and the presence of soap in the household. Two-hundred grams of soap per person was distributed monthly. RESULTS Households had soap on average only 38% of the interview days. Soap was used primarily for bathing and washing clothes (86%). Although 81% of mothers reported washing their children's hands, only 28% of those mothers used soap for that purpose. The presence of soap in a household showed a significant protective effect: there were 27% less episodes of diarrhoea in households when soap was present compared to when no soap was present (RR = 0.73, 95% CI: 0.54 < RR < 0.98). Potential confounding factors were assessed and did not appear to be responsible for the association between the presence of soap and reductions in diarrhoea incidence. CONCLUSION In summary, our findings suggest that the provision of regular and adequate soap rations, even in the absence of a behaviour modification or education programme, can play an important role in reducing diarrhoea in refugee populations. If subsequent study confirms the soap as a cheap and effective measure to reduce diarrhoea, its provision in adequate amounts should be a high priority in refugee settings.

Abstract
Populations affected by armed conflict have experienced severe public health consequences mediated by population displacement, food scarcity, and the collapse of basic health services, giving rise to the term complex humanitarian emergencies. These public health effects have been most severe in underdeveloped countries in Africa, Asia, and Latin America. Refugees and internally displaced persons have experienced high mortality rates during the period immediately following their migration. In Africa, crude mortality rates have been as high as 80 times baseline rates. The most common causes of death have been diarrheal diseases, measles, acute respiratory infections, and malaria. High prevalences of acute malnutrition have contributed to high case fatality rates. In conflict-affected European countries, such as the former Yugoslavia, Georgia, Azerbaijan, and Chechnya, war-related injuries have been the most common cause of death among civilian populations; however, increased incidence of communicable diseases, neonatal health problems, and nutritional deficiencies (especially among the elderly) have been documented. The most effective measures to prevent mortality and morbidity in complex emergencies include protection from violence; the provision of adequate food rations, clean water and sanitation; diarrheal disease control; measles immunization; maternal and child health care, including the case management of common endemic communicable diseases; and selective feeding programs, when indicated.

Abstract
Serogroup A meningococcus epidemics occurred in refugee populations in Zaire in August 1994. The paper analyses the public health impact of a mass vaccination campaign implemented in a large refugee camp. We compared meningitis incidence rates from 2 similar camps. In Kibumba camp, vaccination was implemented early in the course of the epidemic whilst in the control camp (Katale), vaccination was delayed. At a threshold of 15 cases per 100 000 population per week an immunization campaign was implemented. Attack rates were 94 and 134 per 100,000 in Kibumba and Katale respectively over 2 months. In Kibumba, one week after crossing the threshold, 121,588 doses of vaccine were administered covering 76% of all refugees. Vaccination may have prevented 68 cases (30% of the expected cases). Despite its rapid institution and the high coverage achieved, the vaccination campaign had a limited impact on morbidity due to meningitis. In the early phase in refugee camps, the relative priorities of meningitis vaccination and case management need to be better defined.

Abstract
Since the end of the Cold War, there has been a dramatic increase in civil conflicts resulting in approximately 50 million refugees and internally displaced civilians. The public health impact of these situations has been immense, comprising high rates of communicable diseases, elevated prevalence of acute malnutrition, and high excess mortality rates. The prevention of these adverse public health effects includes early warning and intervention; prompt supply of adequate food, water, and sanitation; measles immunization; effective management of epidemic communicable diseases; and simple and timely information systems.

Abstract
OBJECTIVES To evaluate the various survey methods used in Somalia between 1991 and early 1993 while assessing documentation of mortality and malnutrition rates and common causes of morbidity and mortality. DATA SOURCES Twenty-three population surveys were identified from the Center for Public Health Surveillance for Somalia, the United Nations Children's Fund, and other humanitarian organizations. STUDY SELECTION Only surveys with defined populations and apparently systematic methodology that focused on mortality, morbidity, and/or nutritional status were included. RESULTS Extensive methodological differences were found among the 23 surveys. Target populations and sampling strategies varied widely. Twelve studies were considered not reproducible. Of the 16 studies assessing mortality, only eight assessed cause of death. Use of units of measurement and inclusion of denominators in rate calculations were inconsistent. None of the studies provided confidence intervals around the point estimates of the rates. Of the 11 studies providing information on morbidity, none provided case definitions. And in the 16 studies reporting nutritional status, a variety of measurement methods and definitions of malnutrition were used. Three studies presented information based on mid-upper-arm circumference measurements, and 10 presented weight-for-height data below 70% and 80% of the reference median; only four studies presented z scores. CONCLUSIONS While the results of some studies may have influenced policy and program management decisions, their effects may have been limited by failure to adequately document results and by differences among studies in objectives, design, parameters measured, methods of measurement, definitions, and analysis methods. We recommend that agencies conducting population studies in emergency situations define clear study objectives, use standard sampling and data collection methods, and ensure precise written documentation of study objectives, methods, and results.

Abstract
OBJECTIVE To implement simplified infectious disease surveillance and epidemic disease control during the relocation of Bhutanese refugees to Nepal. DESIGN Longitudinal observation study of mortality and morbidity. SETTING Refugee health units in six refugee camps housing 73,500 Bhutanese refugees in the eastern tropical lowland between Nepal and India. INTERVENTIONS Infectious disease surveillance and community-based programs to promote vitamin A supplementation, measles vaccination, oral rehydration therapy, and early use of antibiotics to treat acute respiratory infection. MAIN OUTCOME MEASURES Crude mortality rate, mortality rate for children younger than 5 years, and cause-specific mortality. RESULTS Crude mortality rates up to 1.15 deaths per 10,000 persons per day were reported during the first 6 months of surveillance. The leading causes of death were measles, diarrhea, and acute respiratory infections. Surveillance data were used to institute changes in public health management including measles vaccination, vitamin A supplementation, and control programs for diarrhea and acute respiratory infections and to ensure rapid responses to cholera, Shigella dysentery, and meningoencephalitis. Within 4 months of establishing disease control interventions, crude mortality rates were reduced by 75% and were below emergency levels. CONCLUSIONS Simple, sustainable disease surveillance in refugee populations is essential during emergency relief efforts. Data can be used to direct community-based public health interventions to control common infectious diseases and reduce high mortality rates among refugees while placing a minimal burden on health workers.

Abstract
Armenia, a republic of the former Soviet Union, currently suffers from hyperinflation of its currency, a five-year country-wide blockade, and a war with Azerbaijan. Pensioners 60 years of age or older may be at high risk for significant nutritional deficits. We drew a stratified systematic sample (with a random starting point) of 456 pensioner names from all eight administrative regions in Yerevan, the capital of Armenia. We administered a questionnaire that gathered data including self-reported weight and height, demographic characteristics, living conditions, medical and dietary history, income, and aid received from various sources. The survey yielded 381 of 456 (84%) completed interviews. Ninety-one percent reported their diet had gotten worse during the past six months, including less variety (83%) and quantity (85%) of food. Seventy-six percent reported they did not have enough money to buy food, and 91% had cut the size of their meals or skipped meals. Forty-five percent reported a weight loss of > or = 5 kg in the previous year. After we adjusted for potential confounders, weight loss of > or = 5 kg was associated with illness affecting eating (adjusted odds ratio [OR] = 2.2, 95% confidence intervals [CI] = 1.4, 3.4), not having received aid (adjusted OR = 2.2, 95% CI = 1.1, 4.1), and cutting the size of or skipping meals (OR = 2.7, 95% CI = 1.1, 6.7).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The number of refugees and internally displaced persons in need of protection and assistance has increased from 30 million in 1990 to more than 43 million today. War and civil strife have been largely responsible for this epidemic of mass migration that has affected almost every region of the world, including Europe. Since 1990, crude death rates (CDRs) during the early influx of refugees who crossed international borders have been somewhat lower than CDRs reported earlier among Cambodian and Ethiopian refugees. Nevertheless, CDRs among refugees arriving in Ethiopia, Kenya, Nepal, Malawi, and Zimbabwe since 1990 ranged from five to 12 times the baseline CDRs in the countries of origin. Among internally displaced populations in northern Iraq, Somalia, and Sudan, CDRs were extremely high, ranging from 12 to 25 times the baseline CDRs for the nondisplaced. Among both refugees and internally displaced persons, death rates among children less than 5 years of age were far higher than among older children and adults. In Bangladesh, the death rate in female Rohingya refugees was several times higher than in males. Preventable conditions such as diarrheal disease, measles, and acute respiratory infections, exacerbated often by malnutrition, caused most deaths. Although relief programs for refugees have improved since 1990, the situation among the internally displaced may have worsened. The international community should intervene earlier in the evolution of complex disasters involving civil war, human rights abuses, food shortages, and mass displacement. Relief programs need to be based on sound health and nutrition information and should focus on the provision of adequate shelter, food, water, sanitation, and public health programs that prevent mortality from diarrhea, measles, and other communicable diseases, especially among young children and women.

Abstract
A public health assessment during March, 1993, in Bosnia-Herzegovina and in the areas of Serbia and Montenegro hosting Bosnian refugees, revealed extensive disruption to basic health services, displacement of more than 1 million Bosnians, severe food shortages in Muslim enclaves in eastern Bosnia, and widespread destruction of public water and sanitation systems. War-related violence remains the most important public health risk; civilians on all sides of the conflict have been intentional targets of physical and sexual violence. The impact of the war on the health status of the population has been difficult to document; however, in the central Bosnian province of Zenica, perinatal and child mortality rates have increased twofold since 1991. The crude death rate in one Muslim enclave between April, 1992, and March, 1993, was four times the pre-war rate. Prevalence rates of severe malnutrition among both adults and children in central Bosnia have been increasing since November, 1992. Major epidemics of communicable diseases have not been reported; however, the risk may increase during the summer of 1993 when the effects of disrupted water and sanitation systems are more likely to promote enteric disease transmission. Economic sanctions against Serbia and Montenegro may lead to declining health care standards in those republics if basic medical supplies cannot effectively be exempted.

Abstract
Famine and civil war have resulted in high mortality rates and large population displacements in Somalia. To assess mortality rates and risk factors for mortality, we carried out surveys in the central Somali towns of Afgoi and Baidoa in November and December, 1992. In Baidoa we surveyed displaced persons living in camps; the average daily crude mortality rate was 16.8 (95% CI 14.6-19.1) per 10,000 population during the 232 days before the survey. An estimated 74% of children under 5 years living in displaced persons camps died during this period. In Afgoi, where both displaced and resident populations were surveyed, the crude mortality rate was 4.7 (3.9-5.5) deaths per 10,000 per day. Although mortality rates for all displaced persons were high, people living in temporary camps were at highest risk of death. As in other famine-related disasters, preventable infectious diseases such as measles and diarrhoea were the primary causes of death in both towns. These mortality rates are among the highest documented for a civilian population over a long period. Community-based public health interventions to prevent and control common infectious diseases are needed to reduce these exceptionally high mortality rates in Somalia.

Abstract
Since 1988, the Ministry of Health (MOH) of Togo, with technical assistance from CDC, has systematically adapted and strengthened its health information system (HIS) to enable improved monitoring of trends in diseases. The previous system had been hampered by complicated, lengthy reporting forms; incomplete and delayed receipt of reporting forms; absence of mortality reporting; slow, cumbersome manual compilation and analysis methods; and lack of standard case definitions. To simplify the adaptation process, the system was divided into three main activities: data collection, data compilation and analysis, and dissemination of reports and follow-up action. Public health authorities in Togo have built on existing strengths and successfully adapted the HIS to focus on national morbidity and mortality prevention priorities.

Abstract
In Lesotho prior to 1986, diarrhoea was the leading cause of hospital mortality in children less than 5 years of age. At the Queen Elizabeth II Hospital, diarrhoea-related admissions as a proportion of all admissions in children less than 5 years of age declined from 23% in the year prior to the opening of the Oral Rehydration Therapy Unit (ORTU) to 13% in the first nine months of 1987 (p less than 0.05). In addition, the case-fatality ratio of children treated in the ORTU declined from 1.4% in the first quarter of 1986 to zero in the second and third quarters of 1987 (p less than 0.05). In a case-control study conducted to identify reasons for children failing ORTU treatment, factors associated with an increased risk of hospitalization included male gender (odds ratio [OR] = 4.9; 95% confidence limits [CL] = 2.0, 11.9), fever greater than or equal to 38.5 degrees C (OR = 2.0; CL = 1.2, 3.3), undernutrition (OR = 3.2; CL = 1.1, 9.4), and moderate dehydration (OR = 2.3; CL = 1.2, 4.4) or severe dehydration. (OR = 12.1; CL = 3.8, 38.5). Breastfed children less than 2 years of age were at decreased risk of hospitalization (OR = 0.4; CL = 0.2, 0.7). At this major hospital in Lesotho, the standardization of outpatient treatment for diarrhoea with oral rehydration salts (ORS) in the context of an ORTU resulted in a marked decrease in diarrhoea-associated hospitalization and deaths in children less than 5 years of age.

Abstract
More than 30 million refugees and internally displaced persons in developing countries are currently dependent on international relief assistance for their survival. Most of this assistance is provided by Western nations such as the United States. Mortality rates in these populations during the acute phase of displacement have been extremely high, up to 60 times the expected rates. Displaced populations in northern Ethiopia (1985) and southern Sudan (1988) have suffered the highest crude mortality rates. Although mortality rates have risen in all age groups, excess mortality has been the greatest in 1- through 14-year-old children. The major causes of death have been measles, diarrheal diseases, acute respiratory tract infections, and malaria. Case-fatality ratios for these diseases have risen due to the prevalence of both protein-energy malnutrition and certain micronutrient deficiencies. Despite current technical knowledge and resources, several recent relief programs have failed to promptly implement essential public health programs such as provision of adequate food rations, clean water and sanitation, measles immunization, and control of communicable diseases. Basic structural changes in the way international agencies implement and coordinate assistance to displaced populations are urgently needed.

Abstract
Epidemics of communicable diseases pose a direct threat to refugee and internally displaced populations, and could lead to high mortality rates and a disruption of basic health care services. Several large refugee populations live in regions of high meningococcal disease endemicity and their camps are at risk for outbreaks of meningococcal meningitis. Surveillance in these camps allows early detection and control of impending outbreaks. Confirmation of meningococcal disease can be performed under field conditions using simple techniques, such as latex agglutination. Isolates should be obtained for serogroup confirmation and antibiotic sensitivity studies at reference laboratories. Serogroup information is used to determine the risk of widespread epidemic disease and the utility of available vaccines. During epidemics, treatment regimens should be standardized, preferably with an effective single-dose antibiotic. Mass vaccination campaigns should be initiated, the populations at high risk being targeted for vaccination as quickly as possible. When the risk of epidemic disease is deemed to be high, preemptive vaccination may be warranted. Daily surveillance using a simple case definition is essential during an epidemic to determine the effectiveness of control measures and to delineate high-risk groups for vaccination or chemoprophylaxis. Many of these recommendations can be applied also to other populations in developing countries.

Abstract
Outbreaks of measles continue to be a common occurrence among refugee and famine-affected children in emergency relief camps. Extremely high measles-associated mortality rates have been reported from refugee camps--where undernutrition is common--in several countries over the past 10 years. Mortality from measles is, however, preventable, and immunization against the disease is a high priority in emergency relief programmes, second only in importance to the provision of adequate food rations. All children aged 6 months to 5 years should be immunized with measles vaccine as soon as they enter an organized camp or settlement. Should supplies of measles vaccine be inadequate, children in feeding centres, or those otherwise identified as undernourished, are the top priority for immunization. The occurrence of measles in a camp is not a contraindication to conducting an immunization campaign. Strong coordination by a designated lead agency is needed if such campaigns are to be successful; however, cooperation with the local expanded programme on immunization is essential to ensure that existing cold chain equipment, training protocols, and management manuals are used. If additional equipment is necessary, a complete immunization kit developed by the Office of the United Nations High Commissioner for Refugees, the World Health Organization, and Oxfam can be procured from Oxfam headquarters in the United Kingdom. Vitamin A supplements should be given routinely at the time of measles immunization in situations where malnutrition is severe. Mortality and morbidity in children with clinical measles can be reduced by administering high doses of vitamin A.

Abstract
A review of mortality data from refugee camps in Thailand (1979-80), Somalia (1980-85), and Sudan (1984-85) indicates that crude mortality rates (CMRs) were up to 40 times higher than those for the non-refugee populations in the host countries. In eastern Sudan, approximately 5% of the population of eight camps died in the first 3 months of the emergency and daily CMRs as high as 14 per 10 000 were reported. These rates dropped to values comparable with those of the host country within 6 weeks in the Thai camps; however, in Somalia and Sudan this process took 12 months. Mortality rates among under-5-year olds in the early phases, which were as high as 32.6 per 10 000 per day, are six times greater than those in the world's least developed countries during non-emergency times. Among severely undernourished children in one camp in Sudan, the death rate reached 114 per 10 000 per day. Acute respiratory infections, diarrhoeal diseases, malaria, measles, and undernutrition were the causes of most reported deaths, the majority of which could have been prevented by adequate food rations, clean water, measles immunization, and an oral rehydration programme.
