Article Synopsis
- Trachoma is aimed for global elimination by 2030, with a focus on using IgG antibody measurements in children for monitoring and decision-making in public health programs.
- There are no existing guidelines for using serology in trachoma control, highlighting a larger issue in the field of disease elimination and epidemiology.
- Researchers analyzed IgG levels in 63,911 children from various regions to determine seroconversion rates and proposed a method to assess when population transmission falls below or exceeds intervention thresholds, aiding trachoma program strategies.
Many diarrhea-causing pathogens are climate-sensitive, and populations with the lowest socioeconomic position (SEP) are often most vulnerable to climate-related transmission. Household Water, Sanitation, and Handwashing (WASH) interventions constitute one potential effective strategy to reduce child diarrhea, especially among low-income households. Capitalizing on a cluster randomized trial population (360 clusters, 4941 children with 8440 measurements) in rural Bangladesh, one of the world's most climate-sensitive regions, we show that improved WASH substantially reduces diarrhea risk with largest benefits among children with lowest SEP and during the monsoon season.

- - The study explores socioeconomic disparities in HIV testing uptake across sub-Saharan Africa by analyzing data from 25 countries, aiming to identify geographical hotspots for these inequalities and compare local testing rates with HIV prevalence.
- - Utilizing population-based survey data from over 473,000 participants over several years, the research employs various statistical methods, including the Slope Index of Inequality and Getis-Ord Gi* statistics, to assess testing inequalities and their geographical correlations.
- - Findings reveal significant variations in HIV testing inequalities, especially in Western and Central Africa, with notable correlations between testing rates and local HIV prevalence, indicating areas where testing programs may not be effectively addressing the needs.
Objectives: To quantify the burden of COVID-19-related sick leave during the first pandemic wave in France, accounting for sick leaves due to symptomatic COVID-19 ('symptomatic sick leaves') and those due to close contact with COVID-19 cases ('contact sick leaves').
Methods: We combined data from a national demographic database, an occupational health survey, a social behaviour survey and a dynamic SARS-CoV-2 transmission model. Sick leave incidence from 1 March 2020 to 31 May 2020 was estimated by summing daily probabilities of symptomatic and contact sick leaves, stratified by age and administrative region.
Combination HIV prevention aims to provide the right mix of biomedical, behavioral and structural interventions, and is considered the best approach to curb the HIV pandemic. The impact evaluation of combined HIV prevention intervention (CHPI) provides critical information for decision making. We conducted a systematic review of the literature to map the designs and methods used in these studies.

Design: We used cross-sectional population-based surveys between 2010 and 2018.
Methods: Using a potential outcomes framework and the product method, we decomposed the total effect linking wealth and recent (<12 months) HIV testing into direct effects, and indirect effects, via internal (related to individual's ability to perceive need for and to seek care) or external (ability to reach, pay for and engage in healthcare) mediators to calculate the proportion mediated (PM) by each mediator.
Article Synopsis
- - The study monitored socioeconomic inequalities in HIV prevention services across 18 countries in sub-Saharan Africa from 2010 to 2018, highlighting significant gaps in coverage among different wealth groups.
- - Using data from over 358,000 participants, the researchers found that inequalities were particularly severe in condom use and attitudes toward people with HIV, with wealthier individuals exhibiting much higher rates of these preventive measures.
- - Despite efforts to improve HIV prevention, the study concluded that substantial socioeconomic disparities persist, especially in West and Central Africa compared to the East and Southern regions.
Background: Workplace absenteeism increases significantly during influenza epidemics. Sick leave records may facilitate more timely detection of influenza outbreaks, as trends in increased sick leave may precede alerts issued by sentinel surveillance systems by days or weeks. Sick leave data have not been comprehensively evaluated in comparison to traditional surveillance methods.
View Article and Find Full Text PDFBackground: Overall increases in the uptake of HIV testing in the past two decades might hide discrepancies across socioeconomic groups. We used data from population-based surveys done in sub-Saharan Africa to quantify socioeconomic inequalities in uptake of HIV testing, and to establish trends in testing uptake in the past two decades.
Methods: We analysed data from 16 countries in sub-Saharan Africa where at least one Demographic and Health Survey was done before and after 2008.
