A recent study found that those with COVID-19 were twice as likely to develop hypertension as those with the flu.
According to new research published on August 21, 2023 in the American Heart Association (AHA) journal Hypertension, contracting COVID-19 is associated with developing high blood pressure within six months of having the infection, especially in people with a preexisting heart condition, or those who are older than 40, Black, or male.

Researchers showed that those with COVID-19 had a greater than twofold increased risk of developing hypertension when compared to those with the flu, another respiratory virus.
