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 630 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 percent
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 one 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 the trade in wild animals 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 2002-03 also has been traced to wild animals, with
scientists saying it likely originated in bats, later reaching humans
via civets.
