On the same day, WHO's Emergency Committee said Covid-19 remained a Public Health Emergency of International Concern — its highest level of alert, first declared on January 20, 2020 — amid rising cases, ongoing viral mutation and increasing pressure on already overstretched health systems. In a statement, the committee, which is made up of independent experts, highlighted challenges to the ongoing global Covid-19 response, including a drop-off in testing and spotty genome sequencing, raising the question of just how accurately any nation might reasonably be able to monitor BA.5.
Official data dramatically undercount the true number of infections in the US, epidemiologists say, leaving the nation with a critical blind spot as the most transmissible coronavirus variant yet takes hold. Some experts think there could be as many as 1 million new infections every day in the broader US population — 10 times higher than the official count.
How to manage the new wave
As for how to manage the new wave, Jha urged Americans aged 50 and older to get second booster shots. Adults who are up to date with vaccinations are less likely to be hospitalized than those who are unvaccinated. But only about one in four adults in the US over 50 have gotten their recommended second boosters, data collected by the CDC show.
US health officials are urgently working on a plan to allow second Covid-19 boosters for all adults, a senior White House official confirmed to CNN on Monday, amid fears that younger adults' immunity may be waning as Covid-19 cases rise with the dominance of BA.5.
