Dermatologist Dr. Allison Truong, from Cedars-Sinai Medical Group in Los Angeles, said that she is seeing many patients with this problem.

Patients are complaining of thre...

Since the pandemic began, it's been known that the severity of coronavirus illness varies widely between people. Could the common cold be the reason why?

It's still just a theory, but researchers in California suspect that if you've recently had a cold -- many of which are also caused by coronaviruses -- your immune system's T-cells might recognize SARS-CoV-2 and help fight it.

In the midst of a pandemic, many Americans still view face mask mandates as an assault on their personal freedoms, rather than a means of protecting themselves and others from COVID-19.

But a group of researchers out of Duke University say the mask backlash can be turned around -- as long as efforts to do so are grounded in empathy, not judgment.

As coronavirus cases in the...

A lab-created virus that's similar to but not as dangerous as the new coronavirus could aid efforts to create COVID-19 treatments and vaccines, according to scientists who created it.

Airborne and potentially deadly, the SARS-CoV-2 virus that causes COVID-19 must be studied under strict safety conditions. Precautions include full-body biohazard suits with pressurized respirators, and ...

Facing opposition from President Donald Trump and others, the U.S. Centers for Disease Control and Prevention has issued a document supporting a reopening of the nation's schools this fall.

In a small study from France, an immune-dampening drug used by people battling rheumatoid arthritis showed promise in patients hospitalized with severe COVID-19.

The drug, called anakinra, targets pro-inflammatory responses that kick into high gear in advanced COVID-19 -- the so-called "cytokine storm."

A team led by Dr. Gilles Kaplanski, of the Public Assistance Hospital in...

The steroid medication dexamethasone has been proven to help people severely ill with COVID-19. Now a new study hints that other drugs in the same class may also work -- in the right patients.

The findings are from a review of one hospital's experience, not a clinical trial. So researchers said the results should be interpreted with some caution.

But the study suggests that ...
