Turn out the lights for a good night of sleep: this seems like common sense, but many Americans don't actually follow it. New research shows it doesn't take much light at night to hurt our health.

Though findings are preliminary, many studies suggest that vaccinated people have good protection against the condition, although just how much is still up for debate.

Many who are vaccinated against COVID-19 are worried an infection may lead to long COVID. The latest research shows that can happen, but the chance is much lower among those who're vaccinated.

New CDC guidance puts most of the U.S. at low risk of COVID-19. But what does that actually mean? Experts says the CDC metrics aren't necessarily the best way to gauge your individual risk.

After recovering from their initial illness, COVID-19 patients can sometimes suffer serious complications such as heart attacks and strokes — even up to a year later. New research quantifies the risk.

The Centers for Disease Control and Prevention says many Americans can now shed their facemasks. But if you aren't ready do that, one-way masking still offers protection — if you do it right.

Doctors and health researchers are looking to testing rates, case rates – and intuition – to determine when they'll feel comfortable mingling maskless indoors.

Even as the CDC endorses the end of mask mandates in many areas, some folks still want to wear a mask in public places to reduce the risk of a coronavirus infection. Here's a guide to one-way masking.

After recovering from the initial illness, some COVID-19 patients suffer serious complications such as heart attacks and strokes. A study has quantified the risks up to a year later.

The omicron surge precipitated a critical blood shortage — the worst in over a decade. It is threatening access to treatments for patients with cancer and other medical conditions.

When cancer survivor Katie Ripley got pneumonia, the 25-bed hospital in her small town didn't have the specialized care she needed. But with omicron surging, there was no ICU bed to transfer her to.

The omicron surge has clogged up the health care system, from the ICU to the ER. The consequences are huge for smaller hospitals and, in some cases, it has led to irreparable harm.

More than 900,000 people in the U.S. have now died from COVID-19, but that figure doesn't capture the full impact of the disease.

Slammed by COVID-19, many U.S. hospitals have put off essential procedures. Delays are leading to consequences like heart attacks and sending people to emergency rooms to get care.

The omicron surge is derailing medical care for all kinds of patients. While it's hard to quantify, doctors say many patients are suffering because of canceled surgeries and clogged hospitals.

People who get infected with omicron are less likely to go to the hospital, go on a ventilator or die. But with the current huge volume of patients, hospitals are still struggling to treat them all.

This latest coronavirus surge has set back a return to "normal." COVID is never going away -– and that has implications for hospitals, schools and public health officials.

Omicron has pushed U.S. hospitalizations to record levels, but what does an omicron illness actually look like? And who is getting very sick? Doctors around the country describe what they are seeing.

A Seattle hospital confronts the omicron surge. While COVID-19 patients aren't as sick compared to earlier waves, there is a record number of patients overall, and not enough staff to care for them.

Omicron may cause milder disease, but the sheer number of patients makes this wave far worse for the health care system. With packed emergency rooms, patients can wait days to get moved to a bed.
