Why COVID boosters werent tweaked to better match variants Fauci says COVID-19 deaths will soon start to go down A new sub-lineage of the highly contagious Delta variant that is.

. A variant is a viral genome genetic code that may contain one or more mutations. Delta has become the dominant strain in some countries such. Vaccines continue to reduce a persons risk of contracting the virus that causes COVID-19 including this variant.

1 the variant is no longer circulating 2 the variant has been circulating for a long time without any impact on the overall epidemiological situation 3 scientific evidence demonstrates that the variant is not associated with any concerning properties. A variant of interest is a coronavirus variant that compared to earlier forms of the virus has genetic characteristics that predict greater transmissibility evasion of immunity or diagnostic testing or more severe disease. Currently one variant of the virus SARS-CoV-2 that causes coronavirus disease 2019 COVID-19 is creating concern in the US.

I wouldnt be incredibly surprised if something else came along thats even more transmissible Eric Vail director of molecular pathology at Cedars-Sinai Medical Center told Newsweek. Multiple scientists told Newsweek back in August that there was a potential doomsday COVID variant that could be worse than the delta variant which has proven to be highly transmissible. COVID-19 may well continue to evolve into new widely spreading variants but theres reason to think that none of them are likely to routinely blow.

By David McKenzie and Ghazi Balkiz CNN. The Covid delta variant that was originally discovered in India is now spreading around the world. The Delta variant causes more infections and spreads faster than earlier forms of the virus that causes COVID-19.
