Which animals could have passed Covid-19 to humans?
PARIS: First it was snakes, then the endangered pangolin before badgers were put in the quay.
Scientists scrutinized a Noah's ark of animals to find out if – and how – the coronavirus was transmitted from bats to humans, shifting the prime suspect from one study to another.
Cats, dogs, badgers, lions and tigers have also been in the spotlight – not to mention minks, which have been culled into the millions.
After AFP published the findings of an expert report convened by the World Health Organization (WHO) on Monday, here is a summary of the suspects.
Scientists were quick to accuse the bat of being the origin from the time the virus emerged in China in late 2019.
A study sponsored by the Chinese Academy of Sciences in January 2020 found that Covid-19 was closely related to a species found in bats, which is said to be the “native host”.
Bats are hosts to many other types of coronavirus.
But the scientists say Covid-19 must have passed through another species yet to be identified known as an "intermediate host."
A second study published shortly afterwards in the Journal of Medical Virology identified snakes as a possible culprit.
The report was immediately pushed aside by other experts who said the culprit was likely a mammal, as was the case with SARS, which came from the civet, a small nocturnal animal prized in China for its meat.
Researchers at South China Agricultural University said in February 2020 that the endangered pangolin, a mammal whose scales are used in Chinese medicine, could be the "missing link" between bats and humans.
This anteater was one of the wild animals sold in the Huanan Market in the central Chinese city of Wuhan, to which most of the earliest known cases of Covid-19 were associated.
But whether the pangolin is the culprit is not known at this stage.
A dog was quarantined in Hong Kong later that same month after testing "weak positive" for the virus when its owner was infected.
Cases were then reported in cats.
Ferrets and hamsters have also tested positive, as have tigers and lions in captivity.
Scientists have stressed that pets are vulnerable to the virus, but cannot infect humans.
Suspicion has also fallen on mink, which is bred for their valuable fur.
In June, the WHO said Dutch workers apparently infected with the coronavirus by mink could be the first known cases of animal-to-human transmission.
Cases of Covid in mink farms were subsequently discovered in several other countries of the European Union, including Denmark, France, Greece, Italy, Lithuania, Spain, and Sweden, as well as the United States.
In July, tens of thousands of minks were culled in the Netherlands, and hundreds of thousands more followed a month later when the government introduced a total ban on the industry until the end of the year.
Denmark – which had three times more minks than humans – ordered the culling of all 15 to 17 million minks from the country in November.
Copenhagen warned that the mink mutation called "Cluster 5" could threaten the effectiveness of any future vaccine.
A mission of WHO international experts visiting Wuhan found no shortage of suspects, from badgers to raccoons to civets.
Their highly anticipated report, obtained by AFP Monday, said it was "likely to very likely" that the virus jumped from bats to humans through an intermediate host, but they were unable to say what that missing link might be.
In fact, it was also "possible" that the virus jumped directly from bats, they added.
