SARS-related coronaviruses infect around 66,000 people a year in SE Asia

About 66,000 people in Southeast Asia are infected each year with SARS-related coronaviruses, and nearly 500 million people live near habitats where bat hosts of those viruses are found, according to a study released on Wednesday.
The research, published by Nature Communications, said viral transmission from bats to humans may have been “substantially underestimated”, adding that its mapping of bat species in the region could aid efforts to determine the origins of COVID-19.
The researchers focused on 26 species of bat known to host SARS-like coronaviruses in a region of 5.1 million square kilometres, stretching from China to Southeast and South Asia. They then incorporated data on antibody levels among people who have reported bat contact.
Southern China, northeastern Myanmar, Laos and northern Vietnam were identified as the regions with the highest diversity of bat species that host SARS-like coronaviruses (SARSr-CoVs).
