As the BA.5 variant spreads, the risk of coronavirus reinfection grows
July 11, 2022
America has decided the pandemic is over. The coronavirus has other ideas.
The latest omicron offshoot, BA.5, has quickly become dominant in the United States, and thanks to its elusiveness when encountering the human immune system, is driving a wave of cases across the country.
The size of that wave is unclear because most people are testing at home or not testing at all. The Centers for Disease Control and Prevention in the past week has reported a little more than 100,000 new cases a day on average. But infectious-disease experts know that wildly underestimates the true number, which may be as many as a million, said Eric Topol, a professor at Scripps Research who closely tracks pandemic trends.
