One of the common expressions apart for flu symptoms, cough and breathing difficulty, in a group of patients in any age group, is the tendency to of the blood to clot anywhere in the blood vessels secondary to being Covid19 positive. The exact mechanism is being investigated. But this tendency results in strokes, heart attacks, and various other complications caused by Blood Clots in the blood vessels - Dr. Leela

Known as large vessel occlusions, or LVOs, they can obliterate large parts of the brain responsible for movement, speech and decision-making in one blow because they are in the main blood-supplying arteries.
Many researchers suspect strokes in covid-19 patients may be a direct consequence of blood problems that are producing clots all over some people’s bodies.
Clots that form on vessel walls fly upward. One that started in the calves might migrate to the lungs, causing a blockage called a pulmonary embolism that arrests breathing — a known cause of death in covid-19 patients. Clots in or near the heart might lead to a heart attack, another common cause of death. Anything above that would probably go to the brain, leading to a stroke."
