One concentration of jump zones includes a region of mountains and lakes about 175 km southeast of the Wuhan market. These areas, termed “ jump zones” by the news agency, combine factors including tree loss, precipitation and bat species to create conditions where spillovers are most likely.īetween 20, the data show, jump zones in the country expanded by 54%, an increase of nearly 150,000 sq km, an area larger than Nepal.

REUTERS/Stringer/Thomas PeterĪ Reuters data analysis found that human encroachment on bat habitats in recent decades has turned parts of China into an epidemiological minefield. TWO THEORIES: A person in protective gear outside the market in Wuhan, China, where some scientists say the COVID-19 virus likely leapt from animals into humans. Chinese court records are replete with cases of poachers taking wildlife from risky areas, and scientists from the Wuhan lab have collected bat samples there. Though it remains a mystery how the virus got to Wuhan, spillover risk has been increasing dramatically in China, including several regions within 400 km of the market. The specific basis for the assessments hasn’t been publicly disclosed.

agencies that have studied the matter lean toward natural spillover, although also inconclusively.

Department of Energy, with “low confidence,” in a report said that a lab leak was likely.

Others suspect the pathogen somehow leaked from a Wuhan laboratory, 27 km from the market, where researchers study bat viruses. The idea gained more traction earlier this year when the U.S. The animals, known to be susceptible to bat viruses, included raccoon dogs, bamboo rats and porcupines.Īlthough not conclusive, some scientists said the data add evidence to the theory that the virus jumped from animals to humans through what is known as “zoonotic spillover,” a source of many infectious diseases in humans. The previously undisclosed data indicated the presence of wild animals in the same section of the market where the team had found SARS-CoV-2. But in the three years since COVID-19 emerged, researchers have been unable to determine how it infected its first victim, triggering a pandemic that has since killed almost 7 million people, according to an official count by the World Health Organization, and many more if the tally included deaths caused by unreported infections.ĭebate intensified recently after a Chinese research team uploaded DNA evidence, swabbed from the market during the outbreak, to an international gene sequence database.
