Background: To prevent dehydration and malnutrition in children with diarrhea, it is important they get good management at home. The caregivers should commence home remedies immediately before they seek medical advice. This study assessed the level of knowledge on home management of diarrhea among caregivers of children below five years with diarrhea.Methods: This research applied descriptive cross-sectional study design. The current study was a household survey targeting caregivers of children below five years with diarrhea. The Cochran's sample size formula was used to calculate a sample size of 345 respondents. Purposive sampling was used to recruit respondents in the study. The study employed a researcher- administered semi-structured questionnaire and use of a checklist. Descriptive statistics and chi-square tests were used in the analysis.Results: The study found that that slightly above half 52.2% (n=180) of the respondents had low knowledge on management of diarrhea. There was a significant relationship (χ2=4.044, df=1, p<0.044) between respondent’s’ level of education and knowledge of home management of diarrhea. Cross tabulation showed that 60.2% of those who had low education also had low knowledge.Conclusions: The study concluded that the level of knowledge on home management of diarrhea among caregivers of children below five years with diarrhea was low. Level of education was a significant predictor of knowledge whereby low knowledge was associated with low education. The study recommends enhanced education of mothers on home management of diarrhea by nurses.

AbstractPopulation based data on COVID-19 are essential for guiding public policies. We report on the first of a series of planned seroprevalence surveys relying upon on household probabilistic samples of 133 large sentinel cities in Brazil, including 25,025 participants from all 26 states and the Federal District. Seroprevalence of antibodies to SARS-CoV-2, assessed using a lateral flow rapid test, varied markedly across the country’s cities and regions, from below 1% in most cities in the South and Center-West regions to up to 25% in the city of Breves in the Amazon (North) region. Eleven of the 15 cities with the highest seroprevalence were located in the North, including the six cities with highest prevalence which were located along a 2,000 km stretch of the Amazon river. Overall seroprevalence for the 90 cities with sample size of 200 or greater was 1.4% (95% CI 1.3–1.6). Extrapolating this figure to the population of these cities, which represent 25% of the country’s population, led to an estimate of 760,000 cases, as compared to the 104,782 cases reported in official statistics. Seroprevalence did not vary significantly between infancy and age 79 years, but fell by approximately two-thirds after age 80 years. Prevalence was highest among indigenous people (3.7%) and lowest among whites (0.6%), a difference which was maintained when analyses were restricted to the North region, where most indigenous people live. Our results suggest that pandemic is highly heterogenous, with rapid escalation in Brazil’s North and Northeast, and slow progression in the South and Center-West regions.
