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.

COVID-19 may increase the risk of cardiovascular problems, including heart attack, stroke, pulmonary embolism, atrial fibrillation, and heart failure, up to a year after the infection. But vaccination appears to lower these risks. Getting just one dose of a COVID vaccine may halve the risk of myocarditis, a rare condition that causes inflammation of the heart muscle that can arise after viral infections.

While the COVID pandemic changed how many people approached their health, the experience offers a teachable moment about how people can maintain new and improved healthy habits. Four areas that were most affected by COVID and enabled people to create positive changes are exercise, diet, medical check-ups, and social connections.

A 2023 study suggests that women who practice many aspects of a healthy lifestyle are about half as likely as women who don't to experience persistent symptoms after a COVID-19 infection.

While Lyme disease is the most commonly reported tick-borne illness in the United States, a report from the CDC shows that ticks that cause babesiosis are appearing in more parts of the Northeast and Midwest.

Nail-biting can introduce germs into people's mouths that can cause a range of illnesses, including colds or salmonella. The habit also creates tiny fissures in skin that can become infected. People who bite their nails should occupy their mouth and hands with other tasks.

While shortness of breath can be caused by several ailments, the most common are a lung issue, a heart problem, anemia (low red blood cell count), or deconditioning. Even if the cause remains unclear, a doctor can create a treatment plan to improve symptoms.

There’s no evidence that maintaining a healthy lifestyle will suddenly boost the immune system. However, it’s clear that healthy lifestyle habits contribute to overall health, supporting the body’s ability to fight infections instead of creating new problems. Healthy habits that help maintain a robust immune system include getting seven to nine hours of sleep per night, exercising, reducing stress, eating a healthy diet, not smoking, drinking alcohol only in moderation, maintaining a healthy weight, and getting underlying conditions under control.

Many COVID-19 symptoms — such as fever, cough, or muscle aches — overlap with the symptoms of other respiratory conditions, such as influenza, a common cold, or asthma. But there are differences among the conditions. For example, a bout of the flu or a cold will not cause shortness of breath the way COVID-19 will. And while asthma can cause shortness of breath, it won't cause a fever or body aches the way COVID-19 will. A person who's experiencing concerning symptoms of respiratory illness should report them to a doctor.

Although uncommon, heart infections may trigger inflammation that can damage the heart. People should be aware of the risks and symptoms of the three main types: pericarditis (swelling and irritation of the protective, double-layered membrane that surrounds the heart, called the pericardium), myocarditis (inflammation in the middle, muscular layer of the heart), and endocarditis (inflammation that affects the heart’s inner lining or one or more of the heart’s valves).
