Cardiac evaluation: Cardiac disease, angina and pulmonary hypertension should be excluded. COVID 19 or past COVID 19 should be considered. Please see a physician right away to determine whether you require a hospital stay. A baseline EKG 12 lead and pulse oximetry is recommended. Past COVID 19 infection may increase the risk for heart disease, and acute COVID 19 may present in variable ways, but most cases/fever.

Cold, common: If you had your flu shot not likely that. Been hunkered down? Not likely COVID-19. Not hunkered down or masked? Check local guidelines for testing. Otherwise most likely common cold. No flu shot maybe flu Depends on what is going around in your part of the world? Check with local health care folks.
