Note that until this past week, officially, the symptoms had to be the first three defined by CDC, not the eight or so CDC have expanded now: fever, cough, shortness of breath, chills, repeated shaking, muscle pain, headache, sore throat and new loss of taste or smell, could all appear between two and 14 days after exposure. In the field it appears many/most of the less severe cases don’t exhibit the initial set they had defined, so patients experienced illness written off as not COVID-19. From what I’ve heard from the field, a careful patient history finds there was typically a bout of unusual “but it can’t be COVID” illness with a set of the expanded set of symptoms in almost every “asymptomatic” patient. It’s further speculated these variations may have to do with level of exposure and path of infection, along with the earlier noted lung health and comorbidities.
