As scientists discover more animal coronaviruses, they can recognize more parts of SARS-CoV-2 that spread among them. Researchers can recognize which SARS-CoV-2 is. It was also possible to reconstruct what has evolved like this. Evolved To potential human pathogens while still infecting animals.
This pattern is probably followed by many viruses that are now a major burden on human health. For example, HIV is most likely to occur in the early 1900s when West African hunters were infected with a virus that infects chimpanzees and other primates.
However, some scientists thought it was too early to conclude that the same thing happened with SARS-CoV-2. After all, the coronavirus first came to light in Wuhan, the home of the Wuhan Institute for Viral Science, where researchers study dozens of coronavirus strains collected in caves in southern China.
Still, it’s very likely a coincidence that the top laboratories studying this family of viruses are in the same city where the epidemic occurred. Wuhan is a bigger city than New York. It is the center of the city and is constantly receiving visitors from other parts of China. There are also many large markets for wildlife brought in from all over China. When placed in densely populated areas of wildlife, the virus can move from species to species, sometimes causing dangerous recombination leading to new diseases.
Research at the institute began after another coronavirus led to the SARS outbreak in 2002. Researchers soon sold a closely related species of the virus, called SARS-CoV, to bats and the Chinese market. Found in a civet cat that is. With this discovery, scientists have turned to all animal coronaviruses that may initiate a new pandemic across species boundaries.
Virologists can take a variety of steps to reduce the risk of getting the virus they are studying. However, over the years, several accidents have occurred. Researchers got sick and infected others with an experimental virus.
2004For example, researchers at the National Institute of Virology in Beijing were infected with the coronavirus that causes SARS. She gave it to others, including her mother, who died of an infection.
