As BA.5 spreads, the White House warns that Covid is not over.

President Biden’s coronavirus response team warned Americans on Tuesday that they must do more to protect themselves against Covid-19, as the highly transmissible Omicron subvariant known as BA.5 fuels a new wave of infections, re-infections and hospitalizations across the country.

But their new strategy to combat the threat sounded a lot like the old one, couched as advice that they hope more people will follow: Get vaccinated or boosted even if you have already been infected; test if you feel sick; seek out therapeutics if you test positive and wear masks in crowded indoor spaces.

“Variants will continue to emerge if the virus circulates globally and in this country,” Dr. Anthony S. Fauci, Mr. Biden’s chief medical adviser for the pandemic, said at a White House news briefing. “We should not let it disrupt our lives. But we cannot deny that it is a reality that we need to deal with.”
