Cold & Flu Archive

The flu virus triggers bodywide aches and pain by causing inflammation. People can ease flu aches by staying hydrated; taking warm showers; and using over-the-counter anti-inflammatory drugs such as ibuprofen (Advil, Motrin) or naproxen (Aleve).

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don't change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

Learn which vaccines can help protect you against serious illness and hospitalization from RSV, COVID, and the flu this fall.

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.

Experts say many over-the-counter cough medicines are ineffective, and that those suffering from a cold-related cough should take an antihistamine with a nasal decongestant.

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.

Because aging makes it harder to fight off infections, it's especially important for people to stay up to date on vaccinations as they get older. Important vaccinations include those that ward off COVID-19; tetanus, diphtheria, and pertussis; shingles; and pneumococcal diseases. Flu vaccinations are also important and are needed yearly. There are a few different types of flu shots. Doctors advise getting whatever flu vaccine is readily available. If there's a choice, the latest recommendation in 2022 for people 65 or older is to have the high-dose flu shot rather than the regular-dose version.

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.

Sinusitis occurs when blocked sinuses cannot drain and the backed-up mucus gets infected. The simplest and often most effective treatment is daily nasal irrigation. It can also help to drink a lot of water, inhale steam, and sleep with the head elevated.
