One of the hallmarks of a COVID-19 infection has been a lost sense of smell after the infection ends.

In a new study, researchers blame an ongoing immune assault on the olfactory nerve cells — cells found at the top of the nasal cavity — and a decline in the number of those cells. The study was led by a team at Duke Health in Durham, N.C.

Public health experts have been warning of a “tripledemic” of respiratory viruses this fall and winter, so the American Lung Association has some tips for breathing easier this holiday season.

Flu, respiratory syncytial virus (RSV) and COVID-19 are all spreading throughout the United States, overwhelming health care systems.

One way to make holiday or seasonal gatherings safer ...

A nationwide group of infection control experts recommends U.S. health care facilities stop testing patients for COVID-19 before hospital admission or scheduled surgeries if they have no virus symptoms.

The Society for Healthcare Epidemiology of America (SHEA) statement says facilities should rely instead on enhanced layers of infection prevention.

“The small benefits that could c...

Researchers think they've figured out why people can become reinfected with COVID-19, despite immunity gained from either vaccination or a previous infection.

It turns out that antibodies produced in the nose — the first line of defense against respiratory viruses like COVID — decline faster than antibodies found in the bloodstream, British scientists say.

Nasal antibodies tend ...

Doctors and patients should consider COVID-19 history when planning surgery, according to a new study.

For patients who've had a COVID-19 diagnosis, researchers found significant postoperative problems diminish gradually over time, but risks persist more than a year after the illness.

Researchers may have sniffed out why colds are more likely in wintertime: The answer may lie within the nose.

A previously unidentified immune response inside the nose is responsible for fighting off the viruses that cause upper respiratory infections, according to researchers at Massachusetts Eye and Ear and Northeastern University in Boston.

Unfortunately, cold weather inhibits th...

COVID-19 may harm the liver, a small study suggests.

The virus appears to increase liver stiffness, a sign of potential long-term injury, but it's too early to tell if that portends serious liver disease, the researchers said.

"COVID infections have been observed to cause inflammation and damage to a number of different organ systems like the brain, the intestines and the liver...
