2024 re-emergence of coxsackievirus A24 variant causing an outbreak of acute hemorrhagic conjunctivitis in the South West Indian Ocean

In early 2024, an outbreak of acute hemorrhagic conjunctivitis occurred in Mayotte and in Madagascar, two islands in the Indian Ocean. Real-time diagnosis and genotyping identified a different lineage of coxsackievirus A24 variant (CVA24v) from the current Asian outbreak. Although no recombination e...

Description
Summary:In early 2024, an outbreak of acute hemorrhagic conjunctivitis occurred in Mayotte and in Madagascar, two islands in the Indian Ocean. Real-time diagnosis and genotyping identified a different lineage of coxsackievirus A24 variant (CVA24v) from the current Asian outbreak. Although no recombination event had been detected in all previously reported CVA24v-associated outbreaks associated with the subgenotype IV, we characterized a putative recombinant strain by full-length genome sequencing.
