A virus rapidly spreading in China is also circulating in the United States, causing concern among health experts.

"This is about the time of year when we would expect to see an increase in COVID, flu, RSV, and also norovirus," said Robbie Goldstein, commissioner of the Massachusetts Department of Public Health.

In the midst of pandemic upheaval, researchers have gained fundamental insights about how the body fends off infections.

A little more than 35% of people with persistent long Covid reported that they experienced post-exertional malaise even in the second year.

That’s according to a study published in the Journal of General Internal Medicine earlier this month, which found that 4.5% of people infected with SARS-CoV-2, the virus that causes COVID, developed chronic fatigue. In comparison, only 0.6% of study participants who did not have COVID developed the second condition.

A notice shared via the U.S. Citizenship and Immigration Services website notes immigrants will no longer be asked to show evidence of having received the vaccine. Applications that do not report a COVID vaccination status will not be denied under the change, according to the notice.

With a recent surge in influenza, COVID-19, norovirus, respiratory syncytial virus (RSV), and other respiratory viruses, it's critical to pay close attention to your heart and symptoms—especially if you have heart disease or the risk factors for it.

It's that time of year: highly contagious illnesses like the flu, COVID-19 and Norovirus are spreading in the Tampa Bay area just in time for Saturday's Gasparilla Pirate Fest.

A study suggests that catching COVID-19 significantly raises the risk of developing ME/CFS (formerly called "chronic fatigue syndrome"), a typically lifelong condition that can be debilitating.

Risk of long COVID is higher in women and a link between SARS-CoV-2 infection and development of ME/CFS is shown, according to new studies.

Friday marked five years since a suburban hospital announced it was treating the first confirmed COVID-19 patient in Illinois. At the time, it was only the second COVID case in the United States.

New research emphasizes the need for ongoing COVID-19 protection for people with weakened immune systems, with scalable tests helping identify those most at risk to enable tailored strategies.
