Common viruses sharply raise heart attack and stroke risk, major global review shows

In the largest synthesis to date, researchers reviewed 155 studies linking viral infections, including influenza, SARS-CoV-2, HIV, hepatitis C, and shingles, to increased risks of coronary heart disease, stroke, and heart failure. The findings highlight viral infection prevention and vaccination as underappreciated strategies for cardiovascular protection.
