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.
