COVID-19 infections may raise the risk of developing diabetes, because the virus can damage insulin-producing cells in the pancreas.

It is possible to get shingles more than once. But getting vaccinated with the Shingrix vaccine may help prevent this from occurring.

A rapid heart rate—tachycardia—is a key feature of postural orthostatic tachycardia syndrome, or POTS, a mysterious condition that involves the nervous system and can cause a constellation of symptoms, including fatigue, shortness of breath, headaches, and brain fog, as well as pain in the chest, extremities, or elsewhere in the body. At least half of all cases of POTS are thought to be triggered by an infection (such as mononucleosis), which then spurs inflammation or an autoimmune response. Treatment includes drinking lots of water, eating lots of salt, and graded exercise training.

Evidence suggests that people who've had COVID-19 may have some natural protection against the virus, but will have a much stronger immune response if they also get the vaccine.

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.

Last winter's flu season was mild, partly due to record high rates of flu vaccination and steps people were already taking to protect themselves from COVID-19. But don't let that fool you — some flu seasons are severe, so it it's wise to get a flu shot and take other precautions that can help you stay healthy this winter.

Evidence suggests that people who recover from COVID-19 have an increased risk for developing new health problems, including heart attacks, high blood pressure, diabetes, high cholesterol, muscle inflammation, blood clots that travel to the lungs, strokes from clots or hemorrhages, or psychosis. This is in addition to permanent damage that can result from having COVID, including damage to the lungs, heart, kidneys, brain, or other organs; and debilitating fatigue, difficulty thinking, and other symptoms that make it hard to function normally at work or at home.

Scientists are testing potential vaccines that aim to prevent urinary tract infections (UTIs). Until then, strategies that may help ward off UTIs include drinking lots of water each day, emptying the bladder after sexual intercourse, using vaginal estrogen creams (for women), wiping front to back after gong to the bathroom (for women), taking a daily long-term, low-dose antibiotic, taking a single dose of an antibiotic after sex (if recurrent UTIs often follow sexual intercourse), or taking cranberry supplements.
