Delta Variant Update

The B.1.617.2/Delta variant, first identified in India, has multiple mutations in its spike protein allowing it to be more transmissible than any other variant to date. According to the World Health Organization (WHO), it has spread to at least 85 countries since it was first identified; in the United States, it has been reported in all 50 states and Washington, D.C. The Delta variant is estimated to be up to 60% more transmissible than B.117/Alpha, which was already more transmissible than previous viral strains. As of June 19, the Delta variant accounted for at least 26% of new COVID-19 infections in the U.S. and has now become proportionally the most commonly sequenced strain Indiana. It is critical that Hoosiers get vaccinated when eligible and that providers encourage patients to get vaccinated.
