Origin

Both the outbreaks of SARS and Wuhan started in China— and both are thought to have originated from the wild animal markets. In China, scientists compared the Wuhan corona virus genetic code to other corona viruses and found it to be most similar to two samples of bat corona virus.

The animal species that caused it to spread to humans have not yet been verified by experts but they have some guesses. Scientists believe that the corona virus causing SARS
emerged from a reservoir in bats, which then spread to the civet cat, a wild animal considered a delicacy in parts of southern China, then human.

In the case of this new outbreak, it was traced to the now-shuttered Huanan Seafood Wholesale Market in Wuhan, where a number of wild animals, including raccoon dogs and snakes, were for sale. Experts believe the corona virus was carried by animals— likely snakes— and then transmitted to humans, perhaps from bats again. That's because further genetic analysis found that the snakes closely resembled the genetic building blocks of the Wuhan corona virus. So the researchers believe a bats population could have contaminated rats, which transmitted the virus to humans as they were being sold at the Wuhan Huanan Wholesale Seafood Market. Amid SARS, China has banned civet cats from slaughter and consumption. China has gone a step further this time; the government announced its banning all sales of wild animals across the world.

Nonetheless, another study that contradicts the idea that the virus originated in the Huanan wet market has recently been released. According to Science, which cited a report published in The Lancet medical journal, Chinese scientists found that the first reported case of the Wuhan corona virus since December had no connection to the wet market. Moreover, 13 of the 41 cases they investigated for corona virus had no connection to the Huanan marketplace, the researchers said. The only way to be sure where the virus came from is to take samples of DNA from animals that were sold on that market and from wild snakes and bats in that area.
