Top 3 in the World: The Origin of the Corona Virus in Wuhan, Kamala Harris Acting President

TEMPO.CO, Jakarta – The world’s top 3 news, starting with Covid-19 sufferers, were not from the Wuhan lab. Researchers say the virus originated from traders at the Wuhan Market.

The second news of the world’s top 3 is that scientists found that mice injected with inactivated Covid-19 were more effective at preventing the virus from becoming virulent and deadly. The latest news is that Kamala Harris was appointed acting US president for 85 minutes. Here’s the full news:

1. Researchers Call the First Sufferers of Covid-19 Wuhan Traders, Viruses Not from Labs?

University of Arizona researcher, US, Michael Worobey, stated that the first known Covid-19 case was a market trader in the city of Wuhan, not an accountant who appeared to have no ties to the market but his case contributed to speculation that the virus could have leaked from the laboratory.

The origin of the SARS-CoV-2 virus that causes Covid-19 remains a mystery and a major source of tension between China and the United States. The new analysis by the researcher does not provide a definitive answer to that question.

A joint study by China and the World Health Organization (WHO) this year ruled out the theory that Covid-19 originated in a laboratory, saying the most likely hypothesis is that the virus infects humans naturally, perhaps through the wildlife trade.

The WHO-led team of experts spent four weeks in and around the central city of Wuhan with Chinese scientists and said in a joint report in March that the SARS-CoV-2 virus may have been transmitted from bats to humans via other animals.

The accountant who is widely considered to be the first person with Covid-19, when interviewed, said his first symptoms appeared on December 16, 2019, several days later than reported, said Michael Worobey, head of ecology and evolutionary biology at the University of Arizona, in the comments section. in the journal Science, Thursday, November 18, 2021.

“The onset of symptoms followed several cases in workers at Huanan Market, making a female seafood vendor there the earliest known case, with symptoms of illness starting on December 11,” Worobey said in the article.

He said most of the early symptomatic cases were market-linked, particularly to the west where the raccoons are locked up, providing strong evidence of the pandemic coming from live animal markets.

Worobey is among 18 scientists who have written to Science in May 2021 which called for an investigation into whether the source of the virus could be a laboratory accident.

The WHO last month proposed a new panel of experts to investigate the source of the coronavirus.
