  • A new study suggests that SARS-related coronaviruses similar to COVID-19 infect about 66,000 people each year in Southeast Asia.
  • 2
  • The study also found that nearly 500 million people live near environments where bat carriers of the coronaviruses are found.
  • 3
  • Scientists involved in the research say bats often carry viruses in the same family as SARS-CoV-2, which causes COVID-19.
  • 4
  • The study - recently published in Nature Communications - also suggested that viral infections jumping from bats to humans may have been "substantially underestimated."
  • 5
  • The researchers said their mapping of bat species in Southeast Asia could aid efforts to find the origins of COVID-19.
  • 6
  • The researchers centered on 26 species of bat known to host SARS-like coronaviruses in an area covering 5.1 million square kilometers.
  • 7
  • They then added in data on antibody levels among people who had reported contact with bats.
  • 8
  • Southern China, northeastern Myanmar, Laos and northern Vietnam were identified as the areas with the greatest number of bat species that host SARS-like coronaviruses.
  • 9
  • The researchers said their estimate of 66,000 people becoming infected with SARS-related viruses yearly in Southeast Asia suggests bat-to-human transmissions are common.
  • 10
  • But they noted that such transmissions are usually not identified by current data collecting efforts.
  • 11
  • Meriadeg Le Gouil is a virologist at the University of Caen Normandy in France. He told Nature that while the research is a good starting point, "nature is far more complex than a model."
  • 12
  • Peter Daszak was among the study writers.
  • 13
  • He served on the World Health Organization (WHO) team that investigated the origins of COVID-19.
  • 14
  • The team visited Wuhan, China early last year, where the pandemic was first identified at the end of 2019.
  • 15
  • The WHO said in June that the lack of data from China made it difficult to find out when and how the coronavirus first crossed over into the human population.
  • 16
  • A study published by the journal Science at the end of July suggested that live wildlife trade was still the best explanation for the origins of COVID-19.
