Coronavirus: Pangolins may have spread the disease to humans – Medical News Today

There are many questions about the novel Coronavirus that remain unanswered, such as how does the virus spread? and where did it originate? Now, Chinese-based researchers say they think the pangolin a scaly, otherwise harmless mammal that eats ants may have spread the virus to humans.

When coronaviruses spread to humans, it is usually via contact with an animal that carries the virus.

Medical News Today has recently published an extensive feature on the new virus, explaining that some of the most common carriers for coronaviruses are bats.

However, bats are unlikely to transmit the virus directly to humans, so, as with most similar viruses such as SARS and MERS an intermediary animal is usually the one responsible. For SARS, this was the civet cat, while dromedaries helped spread MERS.

When contacted by MNT a few days ago, The World Health Organization (WHO) said they did not yet know the specific source of the novel coronavirus.

Researchers in China are studying this but have not yet identified a source, they said at the time.

Only a few days later, researchers Shen Yongyi and Xiao Lihua of South China Agricultural University in Guangzhou announced in a press conference that they might have identified the pangolin as the source of the virus.

The announcement, Pangolin is found as a potential intermediate host of new coronavirus in South China, can be found on the universitys website.

Researchers had shown previously that the new coronavirus is most similar to two other bat viruses; in fact, its genomic similarity to these viruses is 88%, which led scientists to believe that bats carried the new virus.

Now, the two researchers used genomic sequencing to compare the DNA of the new coronavirus in humans with that in animals and found a 99% match with pangolins.

This is an extremely interesting observation. Although we need to see more details, it does make sense as there are now some other data emerging that pangolins carry viruses that are closely related to 2019-nCoV, Edward Holmes, an evolutionary virologist at the University of Sydney, Australia, told the prestigious journal Nature.

This latest discovery will be of great significance for the prevention and control of the origin of the new coronavirus, the Chinese university website states.

Liu Yahong, president of the South China Agricultural University, announced at the conference that they would publish the findings soon to help control the virus.

Pangolins a relative of the armadillo and anteaters are scaly mammals that feed on burrowing insects, such as termites and ants.

Pangolins are also an endangered species, and previous research has shown that the coronavirus is likely responsible for killing a large number of Malayan Pangolins.

In China, the countrys law protects the animals, and selling Pangolins can lead to 10 years in prison. However, the animal is a victim of illegal trafficking in fact, researchers describe it as the most poached and trafficked mammal in the world.

The Chinese use the animals scales to treat conditions such as arthritis, menstrual pain, and skin conditions. People also sell the animals meat and consider it a delicacy.

In their efforts to track down the source of the new coronavirus, researchers have suggested that the infection originated at a seafood and wild animal market in Wuhan, China.

Although officially, this market did not sell pangolins, people may have sold the animals there illegally.
