Sneezing, fever, chills, vomiting, coughing — it’s not just one virus wreaking havoc this winter; it’s a combination of four major illnesses.

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.

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.

Over 160,000 people this season have landed in the hospital from flu complications, CDC estimates. More than 6,600 have died. Here are the symptoms.

Two-thirds of people with post-COVID-19 syndrome have persistent, objective symptoms—including reduced physical exercise capacity and reduced cognitive test performances—for a year or more, with no major changes in symptom clusters during the second year of their illness,

Known as human metapneumovirus (hMPV), this virus is one of the viruses that cause the common cold (upper respiratory infection). It belongs to the Pneumoviridae family of viruses, along with respiratory syncytial virus (RSV). It spreads just like other common cold.

Thousands of Oklahomans are sick with the flu. Symptoms of influenza include chills, fever, cough and body aches.

A pandemic is not inevitable, scientists say. But the outbreak has passed worrisome milestones in recent weeks, including cattle that may have been reinfected.

“Overall, female sex was associated with a 1.31-times higher risk of long COVID,” researchers said. “In age-stratified analyses, female sex was associated with the highest risk of long COVID among adults aged 40 to 54 years followed by those aged 55 years or older.”

The Health Department of Northwest Michigan is reporting an increase in respiratory illnesses across Antrim, Charlevoix, Emmet and Otsego counties this winter.

Compared with adults aged 65 and older, those aged 18 to 64 are more affected by long COVID neurologic symptoms.

The finding suggests the agency believes the totality of evidence makes a lab origin more likely than a natural origin, but the agency's assessment assigns a low degree of confidence to this conclusion.
