Delta Variant Predicted to Dominate in the USA

The beta coronavirus that causes COVID-19 is constantly changing through mutation, leading to new variants, including some classified as variants of concern (VOCs), stated the US Centers for Disease Control and Prevention (CDC) on June 25, 2021.

A recent CDC study published on June 11th found that the circulation of SARS-CoV-2 variants in the USA changed rapidly from December 2020 to May 2021, demonstrating how quickly a new variant can emerge.

Currently, several variants are found around the world.

On June 15, 2021, the B.1.617.2 (Delta) variant was classified as a VOC because it spreads from person to person more easily than other variants. Delta has been reported in 77 countries, and in the United Kingdom, it has become the main variant identified in COVID-19 cases.

In the USA, the proportion of Delta variants is predicted to increase to about 20% nationally in late June 2021. Compared with the highest peak in January 2021, the current 7-day average in the USA decreased 95%.

Furthermore, the 7-day average of percent positivity from tests is now 1.7%
