When will a second wave of the coronavirus hit and what will it look like?
Even before the first horrific phase of the COVID-19 pandemic has run its course, scientists are worried about the second wave of the disease.
That’s good news because so many people have contracted COVID-19 from SARS-CoV-2, the virus that causes the disease. Many more probably have had it asymptomatically and didn’t know. Both groups likely have some immunity.What percentage of the population is immune is impossible to know because the United States doesn’t yet have widespread testing, experts say. An answer is likely months away.
“This outbreak has predominantly been on the two coasts. Wave 2 will be in the interior of the county where there are a lot of susceptible people,” he said.Will the coronavirus go away in the summer?Another factor is whether the virus survives longer in cooler, drier weather. That’s why the flu is more common in winter, its virus survives longer and people are more likely to be indoors in close contact.
To prevent that, wide-scale testing will need to be available, and contact tracing must be in place to find everyone who has been exposed and get them to self-isolate for at least 14 days. As states begin to ease restrictions, the United States will effectively become a massive series of experiments. Epidemiologists will be watching carefully, Lipsitch said.
“No one can say when the coast is clear,” said William Hanage, a professor of epidemiology at Harvard’s Chan School of Public Health.
