“Influenza-Like Illness as a Trigger for Ischemic Stroke”, reviewed 36,975 patients hospitalized for stroke. The study concluded acute “influenza-like illness” was a trigger for stroke; and the risk of acute illness triggering a stroke increased with each decade of age. The greatest risk for stroke was within 15 days after the acute illness, but the risk persisted for 60 days. Patients who had an acute “influenza-like illness” prior to a stroke had a higher number of co-morbid conditions, including cardiovascular disorders, rheumatoid arthritis, and depression.

The study also found a correlation between acute “influenza-like illness” in younger patients who suffered a stroke. Patients under age 45 had the highest risk of stroke within 15 days after an acute “influenza-like illness”. The risk of stroke was particularly high if the patient was hospitalized for an acute “influenza-like illness”.

The fact covid-19 can cause blood clots and strokes in patients with co-morbid conditions and in patients under 45 is not surprising, based on what is known about “Influenza-like” illnesses, and the development of blood clots and DIC in severe influenza and in covid-19.
