The Black Church and Public Health: A Key Partnership for Theory Driven COVID-19 Recovery Efforts

The COVID-19 epidemic has negatively impacted the Black community in the United States. Despite current disease mitigation efforts, work is still needed to ensure that Black individuals living in the United States understand their risks regarding COVID-19 infection whether vaccinated or unvaccinated. Thus, the current article posits that the Black church, in concert with public health practitioners, is a venue through which theoretically based health messages should be designed and disseminated regarding COVID-19 recovery efforts. The Health Belief Model and the Harm Reduction approach are posed as theoretical frameworks to facilitate the design of such messages

Etramp5 as a useful serological marker in children to assess the immediate effects of mass drug campaigns for malaria.

INTRODUCTION: Serological methods provide useful metrics to estimate age-specific period prevalence in settings of low malaria transmission; however, evidence on the use of seropositivity as an endpoint remains scarce in studies to evaluate combinations of malaria control measures, especially in children. This study aims to evaluate the immediate effects of a targeted mass drug administration campaign (tMDA) in Haiti by using serological markers. METHODS: The tMDA was implemented in September–October 2018 using sulfadoxine-pyrimethamine and single low-dose primaquine. A natural quasi-experimental study was designed, using a pretest and posttest in a cohort of 754 randomly selected school children, among which 23% reported having received tMDA. Five antigens were selected as outcomes (MSP1-19, AMA-1, Etramp5 antigen 1, HSP40, and GLURP-R0). Posttest was conducted 2–6 weeks after the intervention. RESULTS: At baseline, there was no statistical difference in seroprevalence between the groups of children that were or were not exposed during the posttest. A lower seroprevalence was observed for markers informative of recent exposure (Etramp5 antigen 1, HSP40, and GLURP-R0). Exposure to tMDA was significantly associated with a 50% reduction in the odds of seropositivity for Etramp5 antigen 1 and a 21% reduction in the odds of seropositivity for MSP119. CONCLUSION: Serological markers can be used to evaluate the effects of interventions against malaria on the risk of infection in settings of low transmission. Antibody responses against Etramp5 antigen 1 in Haitian children were reduced in the 2–6 weeks following a tMDA campaign, confirming its usefulness as a short-term marker in child populations
