Why the study?
HFMD is not commonly reported in India, and the study aimed to identify the enterovirus types associated with a large outbreak during the COVID-19 pandemic in 2022.
Highlights the emergence of CVA6 alongside CVA16 as causative agents for HFMD outbreaks in India following the easing of COVID-19 non-pharmaceutical interventions.
Heightened vigilance for CVA6-driven HFMD is warranted in India; leaves open pandemic-related drivers of emergence.
Outbreaks of HFMD in children aged <5 years have been reported worldwide and the major causative agents are Coxsackievirus (CV) A16, enterovirus (EV)-A71 and recently CVA6. In India, HFMD is a disease that is not commonly reported. The purpose of the study was to identify the enterovirus type(s) associated with large outbreak of Hand, foot, and mouth disease during COVID-19 pandemic in 2022. Four hundred and twenty five clinical samples from 196-suspected cases were collected from different parts of the country. This finding indicated the emergence of CVA6 in HFMD along with CVA16, soon after the gradual easing of non-pharmaceutical interventions during-pandemic COVID-19 and the relevance of continued surveillance of circulating enterovirus types in the post-COVID pandemic era.
