United States President Joe Biden on Thursday will present a six-pronged strategy aimed at fighting the spread of the highly contagious coronavirus Delta variant and increasing US Covid-19 vaccinations, a White House official said.

The US is struggling to combat a wave of infections driven by the variant even as officials urge unvaccinated Americans to get the shots. Rising caseloads have raised concerns as children return to school, rattled investors and upended many companies' return-to-office plans.

The official, speaking on condition of anonymity, said Biden “will lay out a six-pronged strategy [...] working across the public and private sectors.”

Nearly 650,000 people in the United States have died from Covid-19 since the pandemic began, according to a Reuters report.
