Expert: Corona Virus Spread to the Corners of the World at the End of 2019


LONDON – genetic Analysis on a sample of more the 7,500 people infected Covid-19 showed the virus was spreading rapidly around the world by the end of 2019 and adapt in the human host.

Studies by experts in Genetics Institute University College London (UCL) found nearly 200 genetic mutations recurring of the virus corona new (SARS-CoV-2), which showed how the virus evolved when spread on human.

“The results that show large proportions of the genetic diversity of the global virus that is found in all countries that have the most victims,” said Professor Francois Balloux at UCL who led the research.

It indicates the virus has spread out into the corners of the world since the beginning of the epidemic. “All viruses mutate naturally. The mutation itself is not a bad thing and no one shows SARS-CoV-2 mutate faster or slower than expected,” he said.

“So far, we can’t state whether SARS-CoV-2 to be more or less deadly and contagious,” he said.

Balloux stated his team has identified 198 mutations or genetic changes are small on the virus. These findings help researchers to develop drugs and vaccines.

“If we focus our efforts on the part of the virus that is less able to mutate, we have better odds of developing a drug that will be effective in the long term,” said Balloux.

A second study released by a team of researchers at the University of Glasgow, Uk, who analysed a sample of the virus. They stated there are only two types of the virus circulating. These findings contrast with early studies of researchers in China in March stating there are two strains of the virus circulating and one of them is aggressive.

More than 3.68 million people have been infected with corona virus and 256,000 gain people died. Infection occurs in more than 210 countries and territories since it first appeared in China in December 2019.

The UCL team to confirm the virus that appear at the end of 2019 before it quickly spread to all corners of the world. (Also read: WHO Push All the State to Investigate Cases Covid-19 the Earliest)
