Post-mortem investigation of role of endemic human coronaviruses (HCoV-NL63, OC43, 229E and HKU-1) in the causal pathway to death amongst children under five in low- and middle-income countries: findings from the Child Health and Mortality Prevention Surveillance (CHAMPS)

Post-mortem investigation of role of endemic human coronaviruses in fatal acute respiratory infections in children in Kenya. SSRN. https://doi.org/10.2139/ssrn.5195408
Abstract Background: Endemic human coronaviruses (HCoV-229E, HKU1, NL63, and OC43) are common causes of mild or asymptomatic respiratory infections in children but are considered rare causes of death. Methods: We evaluated paediatric deaths from January 2017 to December 2022. A panel of experts determined the cause of death (CoD) by…

Postmortem point-of care hemoglobin testing is feasible and potentially accurate among children in South Africa

PLOS Global Public Health, 5(2), e0003997. https://doi.org/10.1371/journal.pgph.0003997
Anemia is an important cause of child morbidity and mortality. Postmortem point-of-care hemoglobin testing is a potential method for assessing anemia at death, but its reliability has not been extensively studied. We aimed to assess the feasibility and validity of postmortem point-of-care hemoglobin assessment using HemoCue in the setting of…

Clinical Infectious Diseases, ciaf098. https://doi.org/10.1093/cid/ciaf098
Background There is paucity of information on the role of cytomegalovirus (CMV) infection as a cause of stillbirths or childhood deaths in low-and middle-income countries (LMICs). We investigated attribution of CMV-disease in the causal pathway to stillbirths and deaths in children <5 years of age in seven LMICs participating in…

Background Listeria monocytogenes is a foodborne pathogen that can lead to severe pregnancy outcomes. This study reports the clinical and genomic characteristics of a Listeria-mediated stillbirth identified in January 2022 through the Child Health and Mortality Prevention Surveillance (CHAMPS) project in Bangladesh. The Lm-BD-CHAMPS-01 isolate was recovered from the blood and cerebrospinal fluid…

Measles deaths highlight immunization program gaps. In the Child Health and Mortality Prevention Surveillance study in Mali, we observed a rise in under-5 measles-related deaths in 2022 that corresponded with increased measles cases at the same time and a decline in measles vaccine coverage in Mali in 2020.
