On-off social distancing may be needed until 2022: Harvard study

Publisher’s Platform: There Is No Premarket Approval for Food, Says the Senior Food Adviser at HHS. Ten Days Earlier His Own Secretary Called the...

A senior adviser at the Department of Health and Human Services spent this week posting three claims about food safety on X, each one preceded by a red exclamation point and the word FACT. As of Thursday, August 20, 2026, CDC counts 10,930 people sick in the federal Cyclospora outbreak, at least 454 of them hospitalized, two

Violence Against Healthcare Workers and Staffing Shortages Fuel Hospital Strikes

Nurse Crystal Dhooghe is used to dealing with blood and broken bones in the emergency room. But she didn’t expect to witness so much violence against her own colleagues. “I’ve seen nurses get shoved, pushed, scratched. The biggest one is bitten,” said Dhooghe, who works at Henry Ford Genesys Hospital in Grand Blanc, Michigan. The

You Want To Join a Clinical Trial. Here’s What To Know About the Hurdles.

Connecting people with clinical trials is complicated — even if people identify a promising match, there’s a slew of potentially thorny factors, including geographic incompatibility, and financial and time considerations. Simply finding an appropriate trial can present an enormous hurdle. In a recent online survey of more than 2,000 adults, 71% of patients with chronic

How Many Exercises You Actually Need to Do to Build Your Back

Peter Muller 5 min read FOR TOO MANY guys, back muscles like the lats and traps get short shrift in training. Not on purpose, of course—after all, who doesn’t want a back that turns heads from behind or fills out a t-shirt like it’s stretched over a Greek statue—but since you can’t see those muscles

The intermittent approach

The intermittent approach

A one-time lockdown won’t halt the novel coronavirus and repeated periods of social distancing may be required into 2022 to prevent hospitals from being overwhelmed, Harvard scientists who modeled the pandemic’s trajectory said. Their study comes as the US enters the peak of its COVID-19 caseload and states eye an eventual easing of tough lockdown measures.

The uncertainity!

The Harvard team’s computer simulation, which was published in a paper in the journal Science, assumed that COVID-19 will become seasonal, like closely related coronaviruses that cause the common cold, with higher transmission rates in colder months. But much remains unknown, including the level of immunity acquired by previous infection and how long it lasts, the authors said.

On-off social distancing

3/5

On-off social distancing

Widespread viral testing would be required in order to determine when the thresholds to re-trigger distancing are crossed, said the authors. The duration and intensity of lockdowns can be relaxed as treatments and vaccines become available. But in their absence, on and then off distancing would give hospitals time to increase critical care capacity to cater for the surge in cases that would occur when the measures are eased. Conversely, too much social distancing without respite can be a bad thing. Under one modeled scenario “the social distancing was so effective that virtually no population immunity is built,” the paper said, hence the need for an intermittent approach.

The drawback

The authors acknowledged a major drawback in their model is how little we currently know about how strong a previously infected person’s immunity is and how long it lasts. At present the best guesses based on closely-related coronaviruses are that it will confer some immunity, for up to about a year. There might also be some cross-protective immunity against COVID-19 if a person is infected by a common cold-causing betacoronavirus.

The virus is here to stay?

The virus is here to stay?

The team said it was highly unlikely that immunity will be strong enough and last long enough that COVID-19 will die out after an initial wave, as was the case with the SARS outbreak of 2002-2003. Antibody tests that have just entered the market and look for whether a person has been previously infected will be crucial in answering these vital questions about immunity, they argued, and a vaccine remains the ultimate weapon. Outside experts praised the paper even as they emphasized how much remained unknown.
