“The biggest risk to the world at the moment is simply Delta,” said microbiologist Sharon Peacock, who runs Britain’s efforts to sequence the genomes of coronavirus variants, calling it the “Fittest and fastest variant yet.”
Evidence is also mounting that it is capable of infecting fully vaccinated people at a greater rate than previous versions, and concerns have been raised that they may even spread the virus, these experts said.
Viruses constantly evolve through mutation, with new variants arising. Sometimes these are more dangerous than the original.
The major worry about the Delta variant , first identified in India , is not that it makes people sicker, but that it spreads far more easily from person to person, increasing infections and hospitalization among the unvaccinated.
