Is there a link between contagious infections and ischemic stroke?

There are some contagious infections such as cytomegalovirus or herpes simplex that can narrow the arteries or cause inflammation that triggers a stroke. Having had an infection within a week of the onset of a stroke is one of the risk factors for an ischemic stroke, also called a cerebral infarction. The best way to reduce your risk of this common type of stroke is to exercise, eat a healthy diet, stop smoking, and control blood sugar, high blood pressure, and cholesterol.
