WHO : Delta variant to become dominant strain in coming months
The World Health Organisation has said the Delta variant of COVID-19 is now present in nearly 100 countries as per conservative estimates, and warned that in the coming months the highly transmissible strain will become the dominant variant of the coronavirus globally.
In its COVID-19 Weekly Epidemiological Update, the WHO said as of June 29, 2021, “96 countries have reported cases of the Delta variant, though this is likely an underestimate as sequencing capacities needed to identify variants are limited. A number of these countries are attributing surges in infections and hospitalisations to this variant.”
Top US infectious disease expert Dr Anthony Fauci on Wednesday warned about the potential emergence of “two Americas” amid the spread of the Delta variant of Sars-CoV-2. Fauci highlighted the disparity in vaccination rates in different regions of the United States to express his concern over the spike in coronavirus disease (Covid-19) cases.
According to the US Centers for Disease Control and Prevention, the ‘variant of concern’ B.1.617.2, first detected in India, accounts for more than one-fourth of the total active Covid-19 cases in the country and has reached nearly every state. The United States has administered at least one dose of the Covid-19 vaccine to over 53% of its population and aims to achieve herd immunity through vaccination as soon as possible.
As per latest figures, cases of the Alpha variant have been reported in 172 countries, territories or areas, Beta in 120 countries (one new country), Gamma in 72 countries (one new country) and Delta in 96 countries (11 new countries).
