Wuhan, China, more than 100 million people have been infected with corona in one year and one month after the first coronavirus confirmed.

We are hoping that the number of confirmed cases will decrease with vaccination, but there is another homework to be solved: mutant virus.

World O Meter, a statistics aggregation site, reported that the cumulative corona 19 confirmed cases around the world exceeded 100 million.



It has been almost a year and a month since the first confirmed cases were confirmed in Wuhan, China at the end of December 2019.



The United States recorded the largest number of confirmed cases, close to 26 million, followed by 1,670,000 in India, and 8.85 million in Brazil.



There were 3 million confirmed cases in Russia, England and France.



The cumulative number of deaths worldwide exceeded 2.14 million.



Vaccinations have started in the UK and the US since the end of last year, but the mutant virus alerts are getting louder.



With the mutant virus spreading to more than 80 countries, a case of mutant virus originating from Brazil was first confirmed in Italy.



Modena Pharmaceuticals said its vaccines were also effective against mutant viruses from the UK and South Africa.



However, it has been found that the South African mutant virus only produces a neutralizing antibody at the level of one-sixth of that of the general coronavirus, resulting in a lower prevention effect.
