. According to the World Health Organisation, the coronavirus mutation that was first observed in Britain has now spread to 50 other countries, whereas a related South African-identified strain has now been detected in 20 countries.
The Agency also announced that the third recent “variant of concern” coronavirus discovered in Japan may affect the immune response and needs further study.
The further the SARS-CoV-2 virus spreads, the more possibilities it has to adapt.
High levels of dissemination could actually mean that we should predict the emergence of more variants, “The more the SARS-CoV-2 virus spreads, the more the chances it has to change. High transmission levels mean that we can foresee the appearance of more models,
The virus that triggers COVID-19 disease is SARS-CoV-2.
The British-identified version VOC 202012/01 has been detected in 50 nations, regions, and areas since it was first confirmed to the WHO on December 14, the agency said.
The WHO also revealed that test findings indicated that the distribution of age and sex was close to that of other circulating variants, although touch tracing details showed “higher transmissibility (secondary attack rates) where the variant strain has the index case”.
In 20 countries, territories and regions, the South African-identified variant 501Y.V2, first recorded on December 18, has now been observed.
The Agency further reported that a new form found in four travelers arriving from Brazil had been alerted by Japan on 9 January. In two adults and two infants, the variant was observed.
“This version has 12 spike protein mutations, including three related mutations common to VOC 202012/01 and 501Y.V2, which may affect transmissibility and the immune response of the host,” it said.”
In addition, the WHO said researchers in Brazil have confirmed the appearance of a related version.
WHO said at a Tuesday meeting of 1,750 foreign scientists that important knowledge gaps and study goals for new variants were discussed.
