Endangered pangolin identified as potential link for coronavirus spread
The endangered pangolin may be the link that facilitated the spread of the novel coronavirus across China, Chinese scientists said on February 7.
Researchers have long suspected that the virus, which has now killed more than 630 people and infected some 31,000, was passed down from an animal to a human at a market in the central Chinese city of Wuhan late last year.
Researchers at the South China Agricultural University have identified the scaly mammal as a “potential intermediate host”, without providing further details.
The new virus is believed to have originated among bats, though 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.
The pangolin is considered the most trafficked animal on the planet and more than 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.
Experts on Friday called for the Chinese scientists to release more data from their research.
Simply reporting the similarity between the genome sequences of viruses is “not sufficient,” said James Wood, a veterinary medicine professor at the University of Cambridge.
