Even if someone has never gotten the flu or COVID-or at least hasn't gotten very sick from them-there still are good reasons to get vaccines that protect against the viruses. Both the flu and COVID viruses can injure the body, making it vulnerable to new major illnesses such as heart, lung, gastrointestinal, or brain disease. But recent solid evidence has shown that vaccines not only reduce the risk of getting the flu and COVID, but also reduce the risk of developing the serious diseases associated with COVID or flu.

Children get sore throats all the time - and most of the time they are nothing to worry about. But it is important for parents to know the common causes of sore throats, and to be aware that that certain instances are serious and should be seen by a doctor immediately.

Cold symptoms can worsen at night for several reasons. Immune cells become more active at night, creating inflammation that aggravates respiratory symptoms. Lower cortisol levels also fuel symptoms, and lying down allows mucus to pool at the back of the throat.

If you hear your child start coughing, it's natural to wonder: could this be the flu, or is it another virus like COVID or RSV, or even a common cold? Here's what to know about similarities between these illnesses and what to do if your child does have the flu.

Millions of Americans get sinusitis each year. The key to a quick recovery is proper drainage, which is best achieved by staying hydrated, inhaling steam several times daily, taking decongestants, and sleeping with the head elevated.

Influenza vaccines that contain higher doses and extra ingredients (adjuvants) to boost their effectiveness can provide better protection than the standard flu vaccine for adults ages 65 and older, according to the CDC, and are recommended for the upcoming flu season.

For some people, the effects of the influenza (flu) virus can lead to a heart attack or cardiac arrest (sudden death). These people typically have reduced blood flow to the heart due to atherosclerosis (narrowed arteries). Because the flu can cause blood oxygen levels to drop to dangerously low levels, it can further reduce the supply of oxygen to the heart, causing a heart attack or cardiac arrest. Fortunately, getting an annual flu shot is associated with reduced risks of a heart attack and related cardiac events.
