Delta surge among unvaccinated will worsen, warn experts amid record US cases

With the United States witnessing a resurgence of coronavirus disease (Covid-19) cases, health experts have warned that the spike is going to worsen, especially in the southern states where the number of unvaccinated people remains high. The US recorded the highest new Covid-19 cases worldwide over the past week as the Delta variant of coronavirus, first detected in India, is wreaking havoc across the globe.

On Friday, the US reported nearly 100,000 new infections, of which southern states contributed the most. Authorities in Florida and Georgia have been urging the residents to get vaccinated as the Southeastern states have reported a worrying surge in Covid-19 cases. While cases in Florida jumped by 50% over the last week, the infection rate in Georgia more than tripled over the last two weeks.

People who are unvaccinated or skip their second dose of vaccine are targets for infection. 

Meanwhile, the US Centers for Disease Control and Prevention has changed its mask guidance for fully vaccinated people, marking a reversal in policy. US President Joe Biden said "in all possibility" new restrictions would be imposed in the US.
