Low-Level #Zoonotic #Transmission of Clade C #MERS-CoV in #Africa: Insights from Scoping Review and Cohort Studies in #Hospital and Community Settings

Abstract Human outbreaks of Middle East respiratory syndrome coronavirus (MERS-CoV) are more common in Middle Eastern and Asian human populations , associated with clades A and B . In Africa , where clade C is dominant in camels , human cases are minimal. We reviewed 16 studies (n = 6198) published across seven African countries between 2012 and 2024 to assess human MERS-CoV cases. We also analyzed data from four cohort studies conducted in camel-keeping communities between 2018 and 2024 involving camel keepers, camel slaughterhouse workers , and hospital patients with acute respiratory illness (ARI). The analysis showed a pooled MERS-CoV prevalence of 2.4% (IQR: 0.6, 11.4) from 16 publications and 1.14% from 4 cohort studies (n = 2353). Symptomatic cases were rarely reported, with most individuals reporting camel contact, and only 12% had travel history to the Middle East. There was one travel-associated reported death , resulting in a mortality rate of 0.013%. The findings suggest a ...

Molecular #diagnosis and phylogenetic #analysis of a #MERS #coronavirus #human case in #Jordan

Abstract Middle East respiratory syndrome coronavirus (MERS-CoV) is an important zoonotic pathogen . The aim of this paper is to report one polymerase chain reaction (PCR)-positive case of MERS-CoV in a 27-year-old man who was involved in a nationwide longitudinal surveillance study of certain zoonotic diseases in Jordan including MERS-CoV. Whole-blood and nasal swab samples were collected from the man and five camels in the vicinity of his living area. The samples were subjected to enzyme-linked immunosorbent assay (ELISA) and real-time reverse-transcription PCR (RT-PCR) to detect MERS-CoV- specific antibodies and MERS-CoV genetic material , respectively. Genomic sequencing and phylogenetic analysis were also performed to detect similarities with known strains of the virus in the region. In January 2021 , an ongoing surveillance study detected a MERS-CoV-positive nasal swab sample from an asymptomatic male and camels using RT-PCR. Phylogenetically, the MERS-CoV isolated in this case b...
