COVID-19 Archive

Infections and deaths from COVID-19 are still occurring every day in the US, although many people are acting like the pandemic is over. So is it over, or not?

Life expectancy is one measure of the general health of a population. In the US, life expectancy had been climbing for more than a century — until the pandemic. After dropping in 2020, it dropped again in 2021, and some population groups fared worse than others.

Autumn is when infectious respiratory diseases start to spread more readily. That's why October is the ideal time to boost your immunity against the viruses that cause flu and COVID-19.

Everyone experiences acute (short-term) diarrhea at some time. The unpleasant experience often resolves on its own in a few days, but there are situations that require medical attention. Examples include bloody diarrhea, severe abdominal pain, a high fever, and episodes that continue for a week or longer. A medical consultation can help determine if diarrhea is related to a specific bacterium or parasite, a medication side effect, a food intolerance, or an inflammatory bowel disease.

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.

A yearly influenza vaccine may help lower the risk of serious cardiovascular complications, especially among people who've had a recent heart attack. Pneumonia and shingles vaccines also help reduce heart attack and stroke risks. Early fall is a good time to get back on track with these vaccines. Several different types of flu shots are available; experts advise getting whichever one is most readily available. For those ages 65 and older who have a choice, three vaccines (Fluzone High-Dose Quadrivalent, Flublock Quadrivalent recombinant, and Fluad Quadrivalent adjuvanted) may offer slightly better protection than the regular-dose shot and are the preferred choice.

Hair loss is common in the months after recovering from COVID-19 infection. It can also happen in people with long COVID or because of mental stress from the pandemic. COVID-related hair loss is a form of telogen effluvium, a condition in which normal hair shedding ramps up after intense physical or mental trauma. Hair regrowth usually takes six to 12 months. People can speed and support hair regrowth by avoiding harsh hair habits, checking nutrient levels, and applying minoxidil (Rogaine) to the scalp.

Few cases of monkeypox have occurred in children during this outbreak, and while the illness is usually mild, it's important for parents to know how to recognize and prevent this virus.

A 2022 study found that survivors of severe COVID-19 infections can develop cognitive problems, such as brain fog or trouble finding words, equivalent to the loss of 10 IQ points or 20 years of aging.

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.
