Technologically and immunologically speaking, Americans should be well prepared to duel a new iteration of SARS-CoV-2, with two years of vaccines, testing, treatment, masking, ventilation, and distancing know-how in hand. Our immunity from BA.1 is also relatively fresh, and the weather’s rapidly warming. In theory, the nation could be poised to stem BA.2’s inbound tide, and make this variant’s cameo our least devastating to date.

But theory, at this point, seems unlikely to translate into practice. As national concern for COVID withers, the country’s capacity to track the coronavirus is on a decided downswing. Community test sites are closing, and even the enthusiasm for at-home tests seems to be on a serious wane; even though Senate Majority Leader Chuck Schumer announced a new deal on domestic pandemic funding, those patterns could stick. Testing and case reporting are now so “abysmal” that we’re losing sight of essential transmission trends, says Jessica Malaty Rivera, a research fellow at Boston Children’s Hospital. “It’s so bad that I could never look at the data and make any informed choice.” Testing is how individuals, communities, and experts stay on top of where the virus is and whom it’s impacting; it’s also one of the main bases of the CDC’s new guidance on when to mask up again. Without it, the nation’s ability to forecast whatever wave might come around next is bound to be clouded.
