I have a sore throat and a bit of a cough. this morning i coughed up mucus with what look like blood. is this a sign of covid 19?

Source of bleeding: There are many causes of the small amount of blood in your sputum. You may have a nasal or upper airway source. Strep infection, influenza are possible causes. COVID-19 typically is associated with fever, dry cough and/or shortness of breath.. Please contact your PCP for an evaluation, possible chest image and evaluation of the source of the bleeding.
