COVID-19 cases are increasing again in the United Kingdom, potentially signaling a future surge in infections in the United States and other countries.
But there’s good news amid the bad. While cases are going up in the U.K., hospitalizations and deaths are increasing more slowly or even declining so far. “This could mean higher transmissible variants, BA.4 or 5, are in play, [and] these variants are much less severe,” Edwin Michael, an epidemiologist at the Center for Global Health Infectious Disease Research at the University of South Florida, told The Daily Beast.
Eric Bortz, a University of Alaska-Anchorage virologist and public-health expert, described BA.4 and BA.5 as “immunologically distinct sublineages.” In other words, they interact with our antibodies in surprising new ways. “There’s a disconnect between the actuality of how infections are happening… and how people are deciding not to take very many precautions,” John Swartzberg, a professor emeritus of infectious diseases and vaccinology at the University of California-Berkeley's School of Public Health, told The Daily Beast. He described it as “COVID fatigue… 100 percent of the world’s population must have it by now.
But it’s possible it won’t. Yes, BA.4 and BA.5 are more transmissible, owing to that mutated spike protein. But that doesn’t mean they’re going to kill a lot of people. Despite their unusual qualities, it could be that BA.4 and BA.5 aren’t actually more dangerous than previous subvariants. Tens of millions of U.K. residents have natural antibodies from past infection. 87 percent of the population is fully vaccinated. 68 percent is boosted. All those antibodies might not prevent breakthrough infections, but they do tend to preventHow bad the current surge in cases gets depends to a great extent on the durability of those antibodies. Immunity, whether from past infection or vaccines, tends to wane over time. But how fast it wanes, and to what effect, is unpredictable.
