What is the Delta Variant?

The Delta Variant is a mutation of the coronavirus, COVID-19, which has been found in more than 80 countries.

The World Health Organization names notable variants after letters in the Greek alphabet. The Delta Variant was named so, after scientists discovered the Alpha, Beta and Gamma variants.

According to the Center for Disease Control, the variants are described as thus: “B.1.1.7 (Alpha): This variant was first detected in the United States in December 2020. It was initially detected in the United Kingdom. B.1.351 (Beta): This variant was first detected in the United States at the end of January 2021. It was initially detected in South Africa in December 2020.

P.1 (Gamma): This variant was first detected in the United States in January 2021. P.1 was initially identified in travelers from Brazil, who were tested during routine screening at an airport in Japan, in early January.

B.1.617.2 (Delta): This variant was first detected in the United States in March 2021. It was initially identified in India in December 2020.This variant was first detected in the United States in March 2021. It was initially identified in India in December 2020. These variants seem to spread more easily and quickly than other variants, which may lead to more cases of COVID-19. An increase in the number of cases will put more strain on healthcare resources, lead to more hospitalizations, and potentially more deaths. So far, studies suggest that the current authorized vaccines work on the circulating variants. Scientists will continue to study these and other variants.

CDC tracks multiple variants circulating in the United States and provides an estimate of how common they are in the nation and at the regional level. This data can change over time as more information is available.

Based on current data, variant B.1.1.7 is the most common variant across the country.”

The variant is responsible now for 90 per cent of all new infections, as cases begin to surge.

Studies have shown that the current vaccines have been effective against these variants.
