  • 3 years ago
US Covid-19 cases are up around 11% over the previous week, almost entirely among people who have not been vaccinated, officials said on Thursday, as the highly infectious Delta variant becomes the dominant Covid-19 strain in the country.

Around 93% of Covid-19 cases in recent days have occurred in counties with vaccination rates of less than 40%, US Centers for Disease Control and Prevention director Rochelle Walensky told a media briefing.

Preliminary data from recent months suggest 99.5% of Covid-19 deaths have occurred in unvaccinated people, she added.
