Mortality and morbidity in refugee camps in eastern Sudan: 1985-90

Communicable diseases in complex emergencies: impact and challenges

Communicable diseases, alone or in combination with malnutrition, account for most deaths in complex emergencies. Factors promoting disease transmission interact synergistically leading to high incidence rates of diarrhoea, respiratory infection, malaria, and measles. This excess morbidity and mortality is avoidable as effective interventions are available. Adequate shelter, water, food, and sanitation linked to effective case management, immunisation, health education, and disease surveillance are crucial. However, delivery mechanisms are often compromised by loss of health staff, damage to infrastructure, insecurity, and poor co-ordination. Although progress has been made in the control of specific communicable diseases in camp settings, complex emergencies affecting large geographical areas or entire countries pose a greater challenge. Available interventions need to be implemented more systematically in complex emergencies with higher levels of coordination between governments, UN agencies, and non-governmental organisations. In addition, further research is needed to adapt and simplify interventions, and to explore novel diagnostics, vaccines, and therapies.

Health programmes and policies associated with decreased mortality in displaced people in postemergency phase camps: a retrospective study

BACKGROUND

An estimated 35 million people have been displaced by complex humanitarian emergencies. International humanitarian organisations define policies and provide basic health and nutrition programmes to displaced people in postemergency phase camps. However, many policies and programmes are not based on supporting data. We aimed to identify associations between age-specific mortality and health indicators in displaced people in postemergency phase camps and to define the programme and policy implications of these data.

METHODS

In 1998-2000, we obtained and analysed retrospective mortality data for the previous 3 months in 51 postemergency phase camps in seven countries. We did multivariate regression with 18 independent variables that affect crude mortality rates (CMRs) and mortality rates in children younger than 5 years (<5 MRs) in complex emergencies. We compared these results with recommended emergency phase minimum indicators.

FINDINGS

Recently established camps had higher CMRs and <5 MRs and fewer local health workers per person than did camps that had been established earlier. Camps that were close to the border or region of conflict or had longer travel times to referral hospitals had higher CMRs than did those located further away or with shorter travel times, and camps with less water per person and high rates of diarrhoea had higher <5 MRs than did those with more water and lower rates of diarrhoea. Distance to border or area of conflict, water quantity, and the number of local health workers per person exceeded the minimum indicators recommended in the emergency phase.

INTERPRETATION

Health and nutrition policies and programmes for displaced people in postemergency phase camps should be evidence-based. Programmes in complex emergencies should focus on indicators proven to be associated with mortality. Minimum indicators should be developed for programmes targeting displaced people in postemergency phase camps.

Refugee density and dependence: practical implications of camp size

Different refugee camps may have widely differing morbidity and mortality rates. Some of these differences are ascribed to environmental factors. This paper reviews the key issues relating to one environmental factor: the size of the refugee camp, and provides a tentative theoretical framework for examining the effect of camp size on refugees. This effect may not be considered because aid workers chronically underestimate the value of the refugees' contribution to their own survival. Large camps settle great numbers of refugees to the hinterland of the camp and limit their access to resources available there. This may increase refugee dependency and vulnerability. There is some slight evidence from the analysis of data provided by Mercer (1992) that child mortality rates (aged 0-4 years) are positively correlated with camp size (as inferred from child populations). If other factors allow, it might be wise for camp planners to try to limit camps to a size which allows refugees reasonable access to local resources.
