Lung Radiation Shows Promise for COVID-19 Pneumonia; Smoking Raises Risks

A low dose of radiation to the lungs of COVID-19 pneumonia patients can help them recover more quickly, a small study suggests. Doctors at Emory University in Atlanta treated 10 such patients with lung radiation and compared them to 10 patients of similar ages who received usual care, without radiation. With radiation, the average time to significant improvement was three days, compared to 12 days in the control group.

Other potential effects included a shorter average time to hospital discharge (12 days with radiation versus 20 days without it) and a lower risk of mechanical ventilation (10% with radiation versus 40% without it). But those two differences were too small to rule out the possibility they were due to chance, the researchers found.

Travelers From Four More States Added to N.Y.’s Mandatory Quarantine

Travelers coming from New Mexico, Minnesota, Wisconsin and Ohio will have to quarantine for two weeks when they arrive in the New York tri-state area, Gov. Andrew Cuomo announced on Tuesday.

They join a growing list that now totals 22 states from which travelers must self-quarantine when they arrive in New York, New Jersey or Connecticut or else face local penalties. The quarantine mandate came as new cases surge elsewhere in the U.S., including hotspots like Florida, Texas, Arizona and California. Delaware, which was briefly subject to the quarantine order, was taken off the list on Tuesday, Cuomo said.
