A Covid-19 variant that likely wreaked havoc during India’s second wave has now spread to 80 countries. The Delta variant, or B.1.617.2, which was first identified in India in October 2020, has now become the dominant strain within the UK, currently accounting for quite 90% of cases there. In the US, too, the amount of Delta variant cases are rapidly rising, up from 10% of the entire Covid-19 cases last week to twenty in the week. consistent with a Financial Times analysis, the delta variant accounts for quite a 3rd of the latest cases every day within the US.
This surge has led Dr. Anthony Fauci, chief medical advisor to the White House, to label the variant because the “greatest threat” to the country’s plan to eradicate Covid-19. Both the united kingdom and the US have high vaccination rates, and it remains to be seen whether their populations are protected against this strain. But in much of the remainder of the planet, where Covid-19 vaccines haven't been administered at an equivalent level, the concerns are even greater.
