The endangered pangolin may be the link that facilitated the spread of the novel coronavirus across China, Chinese scientists said Friday.
At least 31,000 people have been infected and 636 killed by the virus, which has spread to two dozen countries.
Researchers at the South China Agricultural University have identified the scaly mammal as a "potential intermediate host," the university said in a statement, without providing further details.
The new virus, which emerged at a live animal market in central China's Wuhan city late last year, is believed to have originated in bats, but researchers have suggested there could have been an "intermediate host" in the transmission to humans.
After testing more than 1,000 samples from wild animals, scientists from the university found the genome sequences of viruses found on pangolins to be 99% identical to those on coronavirus patients, the official Xinhua news agency reported Friday.
The pangolin is considered the most trafficked animal on the planet and over 1 million have been snatched from Asian and African forests in the past decade, according to the International Union for Conservation of Nature (IUCN).
They are destined for markets in China and Vietnam, where their scales are used in traditional medicine – despite having no medical benefits – and their meat is bought on the black market.
China in January ordered a temporary ban on wild animal trade until the epidemic is under control.
The country has long been accused by conservationists of tolerating a shadowy trade in endangered animals for food or as ingredients in traditional medicines.
The SARS (Severe Acute Respiratory Syndrome) virus that killed hundreds of people in China and Hong Kong in 2002 and 2003 also has been traced to wild animals, with scientists saying it likely originated in bats, later reaching humans via civets.
