Abstract
OBJECTIVE Many children in sub-Saharan Africa die from infectious diseases like malaria, pneumonia, and diarrhoea that can be prevented by early diagnosis, effective and targeted treatment. This study aimed to gain insights into case management practices by parents before they present their children to hospital. METHODS We conducted a cross-sectional study among 332 parents attending a district hospital with their under-fives symptomatic with fever and/or diarrhoea between November 2019 and July 2020 in rural Tanzania. Timely and targeted treatment was defined as seeking health care within 24 h of fever onset, and continued fluid intake in case of diarrhoea. RESULTS The main admission diagnoses were acute respiratory infections (61.8%), malaria (25.3%), diarrhoea (18.4%) and suspected sepsis (8.1%). The majority of children (91%) received treatment prior to admission, mostly antipyretics (75.6%), local herbal medicines (26.8%), and antibiotics (17.8%)-half of them without prescription from a clinician. For diarrhoea, the use of oral rehydration solution was rare (9.0%), although perceived as easily accessible and affordable. 49.4% of the parents presented their children directly to the hospital, 23.2% went to a pharmacy/drug shop and 19.3% to a primary health facility first. Malaria symptoms began mostly 3 days before the hospital visit; only 25.4% of febrile children visited any health facility within 24 h of disease onset. Prior use of local herbal medicine (AOR = 3.2; 95% CI 1.4-7.3), visiting the pharmacy (adjusted Odds Ratio [AOR] = 3.1; 95% confidence interval [CI]: 1.0-9.8), the dispensary being the nearest health facility (AOR = 3.0; 95% CI: 1.5-6.2), and financial difficulties (AOR = 2.2; 95% CI 1.1-4.5) were associated with delayed treatment. CONCLUSION This study suggests that antipyretics and antibiotics dispensed at pharmacies/drug shops, as well as use of local herbal medicines, delay early diagnosis and treatment, which can be life-threatening. Pharmacies/drug shops could be integrated as key focal points for sensitising community members on how to respond to paediatric illnesses and encourage the use of oral rehydration solutions.

Abstract
BACKGROUND Globally, rotavirus infections are the most common cause of diarrhea-related deaths, especially among children under 5 years of age. This virus can be transmitted through the fecal-oral route, although zoonotic and environmental contributions to transmission are poorly defined. The purpose of this study is to determine the epidemiology of rotavirus in humans, animals, and the environment in Africa, as well as the impact of vaccination. METHODS We searched PubMed, Web of Science, Africa Index Medicus, and African Journal Online, identifying 240 prevalence data points from 224 articles between 2009 and 2022. RESULTS Human rotavirus prevalence among patients with gastroenteritis was 29.8% (95% confidence interval [CI], 28.1%-31.5%; 238 710 participants), with similar estimates in children under 5 years of age, and an estimated case fatality rate of 1.2% (95% CI, .7%-2.0%; 10 440 participants). Prevalence was estimated to be 15.4% and 6.1% in patients with nongastroenteritis illnesses and apparently healthy individuals, respectively. Among animals, prevalence was 9.3% (95% CI, 5.7%-13.7%; 6115 animals), and in the environmental water sources, prevalence was 31.4% (95% CI, 17.7%-46.9%; 2530 samples). DISCUSSION Our findings highlight the significant burden of rotavirus infection in Africa, and underscore the need for a One Health approach to limiting the spread of this disease.

Abstract
BACKGROUND Diarrhea is the second most significant cause of child morbidity and mortality, especially in developing countries. The World Health Organization (WHO) advises that mothers and other caregivers be able to recognize the symptoms of dehydration. Therefore, this study aimed to assess the knowledge and behavioral practices regarding diarrhea among mothers in Arar City, Saudi Arabia. METHODS This cross-sectional survey used an anonymous online questionnaire distributed among mothers of children aged one to five years in Arar City. The snowball convenient sampling method was used to recruit the participants. Information on knowledge and behavioral practices regarding diarrhea was obtained from the mothers of children through an electronic questionnaire. The Chi-square test and Fisher's exact test were used to evaluate the relationship between studied variables, as appropriate with statistical significance at P<0.05. RESULTS A total of 479 mothers participated in this survey. Of these, 421 were included in the analysis. Most mothers fall within the age range of 20-40 years (71.1%). A large sector of the studied mothers had high education (72.4%) and was a housewife (40.4%). Most children were above one year old (77.7%). Most participants (69.6%) fell into the moderate knowledge category and 56.3% had moderate behavioral practice scores. Maternal education was significantly associated with knowledge. Furthermore, maternal education and behavioral practice levels were significantly correlated (P < 0.01). CONCLUSION The findings highlight the importance of targeted education programs and community-based interventions to improve mothers' knowledge and promote appropriate behavioral practices related to childhood diarrhea that ultimately will lead to improved health outcomes for children globally.

Global burden and trends of rotavirus infection-associated deaths from 1990 to 2019: an observational trend study. Virol J 2022; 19:166. [PMID: 36266651 PMCID: PMC9585833 DOI: 10.1186/s12985-022-01898-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 10/03/2022] [Indexed: 11/12/2022] Open
Abstract
Background Rotavirus is the leading global pathogen of diarrhea-associated mortality and poses a great threat to public health in all age groups. This study aimed to explore the global burden and 30-year change patterns of rotavirus infection-associated deaths. Methods Based on the Global Burden of Disease 2019 Study (GBD 2019), we analyzed the age-standardized death rate (ASDR) of rotavirus infection by sex, geographical region, and sociodemographic index (SDI) from 1990 to 2019. A Joinpoint regression model was used to analyze the global trends in rotavirus infection over the 30 years, SaTScan software was used to detect the spatial and temporal aggregations, and a generalized linear model to explore the relationship between sociodemographic factors and death rates of rotavirus infection. Results Globally, rotavirus infection was the leading cause of diarrheal deaths, accounting for 19.11% of deaths from diarrhea in 2019. Rotavirus caused a higher death burden in African, Oceanian, and South Asian countries in the past three decades. The ASDR of rotavirus declined from 11.39 (95% uncertainty interval [95% UI] 5.46–19.48) per 100,000 people in 1990 to 3.41 (95% UI 1.60–6.01) per 100,000 people in 2019, with an average annual percentage change (AAPC) (− 4.07%, P < 0.05). However, a significant uptrend was found in high-income North America (AAPC = 1.79%, P < 0.05). The death rate was the highest among children under 5 years worldwide. However, the death rates of elderly individuals over 70 years were higher than those of children under 5 years in 2019 among high, high-middle, middle, and low-middle SDI regions. Current health expenditure, gross domestic product per capita, and the number of physicians per 1000 people were significantly negatively correlated with death rates of rotavirus. Conclusions Although the global trends in the rotavirus burden have decreased substantially over the past three decades, the burden of rotavirus remained high in Africa, Oceania, and South Asia. Children under 5 years and elderly individuals over 70 years were the populations most at risk for rotavirus infection-associated deaths, especially elderly individuals over 70 years in relatively high SDI regions. More attention should be paid to these areas and populations, and effective public health policies should be implemented in the future.

The hospital environment versus carriage: transmission pathways for third-generation cephalosporin-resistant bacteria in blood in neonates in a low-resource country healthcare setting. Sci Rep 2022; 12:8347. [PMID: 35589773 PMCID: PMC9120020 DOI: 10.1038/s41598-022-11626-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 04/26/2022] [Indexed: 11/21/2022] Open
Abstract
Neonatal bloodstream infections (BSI) can lead to sepsis, with high morbidity and mortality, particularly in low-income settings. The high prevalence of third-generation cephalosporin-resistant organisms (3GC-RO) complicates the management of BSI. Whether BSI is linked to carriage of 3GC-RO, or to acquisition from the hospital environment is important for infection prevention and control, but the relationship remains unclear, especially in low-income settings. At a tertiary hospital in Mwanza, Tanzania, we screened neonatal blood and rectal samples from 200 neonates, and 400 (hospital) environmental samples. We used logistic regression to identify risk factors, and Kolmogorov–Smirnov tests and randomisation analyses to compare distributions of species and resistance patterns to assess potential routes of transmission. We found that BSIs caused by 3GC-RO were frequent (of 59 cases of BSI, 55 were caused by 3GC-RO), as was carriage of 3GC-RO, particularly Escherichia coli, Klebsiella pneumoniae, and Acinetobacter species. In the 28 infants with both a carriage and blood isolate, there were more (4 of 28) isolate pairs of the same species and susceptibility profile than expected by chance (p < 0.05), but most pairs were discordant (24 of 28). Logistic regression models found no association between BSI and carriage with either 3GC-RO or only 3GC-R K. pneumoniae. These analyses suggest that carriage of 3GC-RO is not a major driver of BSI caused by 3GC-RO in this setting. Comparison with environmental isolates showed very similar distributions of species and resistance patterns in the carriage, BSI, and the environment. These similar distributions, a high frequency of Acinetobacter spp. isolations, the lack of strong association between carriage and BSI, together with the high proportion of 3GC-RO in BSI all suggest that these neonates acquire multidrug-resistant carriage and blood isolates directly from the hospital environment.

Improved Water and Waste Management Practices Reduce Diarrhea Risk in Children under Age Five in Rural Tanzania: A Community-Based, Cross-Sectional Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19074218. [PMID: 35409904 PMCID: PMC8998175 DOI: 10.3390/ijerph19074218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 03/25/2022] [Accepted: 03/29/2022] [Indexed: 11/17/2022]
Abstract
Diarrhea remains a significant cause of morbidity and mortality among children in developing countries. Water, sanitation, and hygiene practices (WASH) have demonstrated improved diarrhea-related outcomes but may have limited implementation in certain communities. This study analyzes the adoption and effect of WASH-based practices on diarrhea in children under age five in the rural Busiya chiefdom in northwestern Tanzania. In a cross-sectional analysis spanning July-September 2019, 779 households representing 1338 under-five children were surveyed. Among households, 250 (32.1%) reported at least one child with diarrhea over a two-week interval. Diarrhea prevalence in under-five children was 25.6%. In per-household and per-child analyses, the strongest protective factors against childhood diarrhea included dedicated drinking water storage (OR 0.25, 95% CI 0.18−0.36; p < 0.001), improved waste management (OR 0.37, 95% CI 0.27−0.51; p < 0.001), and separation of drinking water (OR 0.38, 95% CI 0.24−0.59; p < 0.001). Improved water sources were associated with decreased risk of childhood diarrhea in per-household analysis (OR 0.72, 95% CI 0.52−0.99, p = 0.04), but not per-child analysis (OR 0.83, 95% CI 0.65−1.05, p = 0.13). Diarrhea was widely treated (87.5%), mostly with antibiotics (44.0%) and oral rehydration solution (27.3%). Targeting water transportation, storage, and sanitation is key to reducing diarrhea in rural populations with limited water access.

Abstract
BACKGROUND Stunting and wasting in children less than 5 years of age are two key indicators of child malnutrition. Reducing their prevalence is a priority of the global public health community and for Somalia, a country suffering complex humanitarian emergencies such as drought, flooding, conflict and large-scale displacements. METHODS Data from the nationally representative cross-sectional Somalia Micronutrient Survey (SMS 2019) on 1947 children were analyzed to assess the prevalence and potential risk factors of stunting and wasting. Bivariate and multivariable analyses were conducted separately for children 0-5 months and 6-59 months, and population attributable fractions were calculated using adjusted risk ratios produced by Poisson regression models. RESULTS Among the 1947 children, the prevalence of stunting and wasting were 17.2% (95% CI: 15.0, 19.6) and 11.0% (95% CI: 9.3, 12.9), respectively. Among children 6-59 months of age, those residing in severely food insecure households had a higher risk of stunting (adjusted risk ratio [aRR] 1.47; CI: 1.12, 1.93) compared to those in food secure households. This risk of stunting was also higher in children with inflammation (aRR 1.75; CI: 1.35, 2.25) and iron deficiency (ID) (aRR 2.09; CI: 1.58, 2.80). For wasting, a dose-response relationship was found with household wealth, with the risk of wasting increasing significantly as the household wealth quintile decreased. On the other hand, the risk of wasting was lower in iron-deficient children (aRR 0.69; CI: 0.49, 0.98) than in iron-replete children. Among children 0-5 months of age no variables remained statistically significantly associated with stunting in the multivariable analysis. Wasting, however, was more common in children with recent diarrhea (aRR 3.51; CI: 1.68, 7.36). CONCLUSIONS Nutritional status of children in Somalia may be improved by prevention of diarrhea and other infections and improvements in household food security.

Abstract
BACKGROUND Diarrhea remains a major cause of morbidity and mortality among children in Tanzania. The purpose of this study was to explore associations between diarrheal disease and water, sanitation, and hygiene (WASH) related behaviors and determine care-seeking predictors for diarrheal disease. METHODS Data from 9996 female primary caregivers were collected as part of a larger integrated nutrition program. Logistic regression was used to measure associations between predictor and dependent variables and diarrheal and care-seeking outcomes. RESULTS Knowledge of the importance of handwashing after assisting a child who has defecated (OR 0.79, CI 0.72-0.87), before preparing food (OR 0.88, CI 0.80-0.97), and before feeding a child (OR 0.89, CI 0.81-0.99) were each associated with not having a child with diarrhea in the past two weeks. Fathers or male caregivers (OR 0.65, CI 0.48-0.89) were less likely to seek medical care for a child with diarrhea. No associations were found between WASH-related knowledge or behavior and seeking medical care for a child with diarrhea. CONCLUSIONS Findings indicate that knowledge of handwashing importance was significant in washing hands after assisting a child who has defecated, before preparing food, and prior to feeding a child. These findings demonstrate the value of parental involvement to lower morbidity and mortality among children.

Adaptation of the small intestine to microbial enteropathogens in Zambian children with stunting. Nat Microbiol 2021; 6:445-454. [PMID: 33589804 PMCID: PMC8007472 DOI: 10.1038/s41564-020-00849-w] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 12/10/2020] [Indexed: 01/30/2023]
Abstract
Environmental enteropathy is a major contributor to growth faltering in millions of children in Africa and South Asia. We carried out a longitudinal, observational and interventional study in Lusaka, Zambia, of 297 children with stunting (aged 2-17 months at recruitment) and 46 control children who had good growth (aged 1-5 months at recruitment). Control children contributed data only at baseline. Children were provided with nutritional supplementation of daily cornmeal-soy blend, an egg and a micronutrient sprinkle, and were followed up to 24 months of age. Children whose growth did not improve over 4-6 months of nutritional supplementation were classified as having non-responsive stunting. We monitored microbial translocation from the gut lumen to the bloodstream in the cohort with non-responsive stunting (n = 108) by measuring circulating lipopolysaccharide (LPS), LPS-binding protein and soluble CD14 at baseline and when non-response was declared. We found that microbial translocation decreased with increasing age, such that LPS declined in 81 (75%) of 108 children with non-responsive stunting, despite sustained pathogen pressure and ongoing intestinal epithelial damage. We used confocal laser endomicroscopy and found that mucosal leakiness also declined with age. However, expression of brush border enzyme, nutrient transporter and mucosal barrier genes in intestinal biopsies did not change with age or correlate with biomarkers of microbial translocation. We propose that environmental enteropathy arises through adaptation to pathogen-mediated epithelial damage. Although environmental enteropathy reduces microbial translocation, it does so at the cost of impaired growth. The reduced epithelial surface area imposed by villus blunting may explain these findings.

Identifying Infants and Young Children at Risk of Unplanned Hospital Admissions and Clinic Visits in Dar es Salaam, Tanzania. Pediatr Infect Dis J 2020; 39:e428-e434. [PMID: 32842043 PMCID: PMC7680284 DOI: 10.1097/inf.0000000000002875] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
BACKGROUND Pediatric inpatient mortality rates are as high as 11% in parts of sub-Saharan Africa. Unscheduled clinic visits also burden children in sub-Saharan Africa. Our objective was to identify factors associated with hospital admissions and unscheduled clinic visits among Tanzanian children < 24 months of age. METHODS We conducted a secondary analysis of 2 trials conducted in Dar es Salaam, Tanzania. We performed univariate and Poisson multivariable regression analyses to identify factors associated with hospital admissions and unscheduled clinic visits. RESULTS Of 4784 children < 24 months of age, 293 (6.1%) were hospitalized at least once and 1308 (27.3%) had ≥ 1 unscheduled clinic visit. Infants and children who were exposed to but HIV-negative had increased risk of hospital admission [adjusted risk ratios (aRR): 3.67; 95% CI: 2.45-5.50; P < 0.001] compared with HIV-unexposed children. Those who were HIV-positive had even higher risk of hospital admission compared with those not exposed to HIV (aRR: 10.87; 95% CI: 7.01-16.89; P < 0.001). Birth weight and breast-feeding status were not associated with increased risk of hospital admission. Children with Apgar scores < 7 (aRR: 1.32; 95% CI: 1.03-1.69; P = 0.001), not exclusively breast-fed up to 6 months of age (aRR: 1.34; 95% CI: 1.12-1.60; P = 0.001), and who were HIV-exposed and HIV-negative (aRR: 2.35; 95% CI: 2.08-2.66; P < 0.001) or HIV-positive (aRR: 3.02; 95% CI: 2.52-3.61; P < 0.001) had higher risk of unscheduled clinic visits. CONCLUSIONS Exposure to HIV and being HIV-positive were associated with the greatest risk for hospital admission and unplanned clinic visits among infants and children in Tanzania. Targeting these vulnerable populations in interventional studies may reduce morbidity.

Abstract
Abstract
Objectives
The decline in diarrhoeal disease-related mortality globally has been attributed to the use of oral rehydration solution (ORS) and zinc supplementation. However, data on ORS and zinc supplementation in Sudan are scarce. We aimed to investigate the access to ORS and zinc treatments and the associated factors, through the analysis of the latest available data from Sudan-Multiple Indicator Cluster Survey (MICS)-2014 obtained from the United Nations Children’s Fund (UNICEF).
Results
A total of 14,081 children were included in this analysis. During the 2 weeks preceding the survey, 29.3% of these children had a diarrhoeal disease. Only 18.9% and 14.8% of these children had received ORS and zinc supplements, respectively. Whereas children from the higher wealth index groups were more likely to receive ORS treatment (fourth group: AOR = 1.301; 95% CI 1.006–1.682), children from rural areas were less likely to receive ORS treatment (AOR = 0.666; 95% CI 0.552–0.803) and zinc supplements (AOR = 0.603; 95% CI 0.500–0.728). The results indicate the existence of unequal access to treatment of childhood diarrhoeal diseases among children under 5 years in Sudan.

Front Vet Sci 2020; 7:532763.

Abstract
Participatory epidemiology (PE) evolved as a branch of veterinary epidemiology and has been largely employed for the control and early warning of infectious diseases within resource-limited settings. It was originally based on combining practitioner communication skills with participatory methods to facilitate the involvement of animal caretakers and owners (embracing their knowledge, experience, and motivations) in the identification and assessment of animal disease problems, including in the design, implementation, monitoring and evaluation of disease control programs, policies, and strategies. With the importance of understanding social perceptions and drivers receiving increasing recognition by epidemiologists, PE tools are being adapted for an increasingly wide range of settings and endeavors. More recently, PE tools have been adapted for use in food and nutrition security programs, One Health activities, wildlife disease surveillance and as part of mixed-methods research across a range of socio-economic settings. This review describes the evolution of PE (in relation to veterinary epidemiology and briefly in relation to public health epidemiology), the underpinning philosophy and principles essential to its effective application and the importance of gender-sensitive approaches and data triangulation, including conventional confirmatory testing. The article also provides illustrative examples highlighting the diversity of approaches and applications of PE, hallmarks of successful PE initiatives and the lessons we can learn when these are missing. Finally, we look forward, describing the particular utility of PE for dealing with emerging infectious diseases, gaining attention of field-level cross-sector officials who can escalate concerns to a higher level and for continuing to raise the voices of those less-heard (such as women, minority groups, and remote communities with limited exposure to formal education) in defining the problems and planning activities that will likely impact directly on their well-being and livelihoods.
