[Note the date. As we open up, we need to keep an eye on the ball, and be prepared to respond again, if necessary. But let's all hope for the best. There's an overseas vacation calling to me!]Coronavirus infections are down across much of the United States. Hospitalizations, too. Deaths are finally dropping from their dismaying late-summer peak of more than 2,000 a day. Most people are vaccinated, and booster shots are gaining approval. Officials in the United States are hoping the worst of the pandemic is over.
But so much depends on the virus itself. It is not static. It mutates. Delta, the variant of SARS-CoV-2 now causing
virtually all infections in the United States, is more than twice as transmissible as the virus that emerged in Wuhan, China. The possibility of further significant mutations in the virus looms like a giant asterisk over any discussion of the trajectory of the pandemic.
In recent weeks, scientists who closely monitor the virus have said it still appears to have plenty of room to evolve.
