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).

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.

Hives are red, itchy welts that crop up on the skin. Allergic reactions and stress, among other triggers, can cause episodes of hives, which typically last several days to a couple of weeks. Cases that last six weeks or longer may be autoimmune hives.

COVID-19 can damage the brain in many ways. Initially, it can cause brain inflammation that causes confusion, difficulty concentrating, and memory problems. COVID also can cause new psychological disorders such as depression or anxiety. It can even cause people to see and hear things that aren't there and to believe things that aren't true. COVID often damages the brain's autonomic nervous system, leading to abnormalities in heart rate and blood pressure. Additionally, the virus that causes COVID can infect and injure the lining of blood vessels and make blood clot more easily, which can lead to strokes and heart attacks.

People who have had shingles have a 30% increased risk for heart disease and stroke, says a new Harvard study. Learn more about the risk.

Getting at least one dose of a COVID vaccine lowers the risk of developing long COVID even among people who were previously unvaccinated and recovered from COVID.

A 2022 observational study that included more than 200,000 people found that those who'd had shingles at some point had a 30% higher long-term risk for a major cardiovascular event, compared with people who didn't have shingles.

Several drugs originally developed to treat type 2 diabetes can help people shed as much as 20% of their body weight—far more than other anti-obesity drugs. Known as incretin mimetics, they also improve blood pressure and cholesterol levels. Up to half of all new-onset diabetes cases in this country are linked to obesity, a disease that now affects more than 40% of Americans. Both conditions are closely linked to cardiovascular disease.

Lifestyle changes like regular exercise, a healthy diet, and sufficient sleep are cornerstones of self-care for people with type 2 diabetes. But can mind-body practices help people manage or even treat type 2 diabetes? An analysis of multiple studies suggests they might.
