The symptoms of COVID-19 — fever, cough, shortness of breath, chills, muscle pain — are widely reported via the media and public health organizations. Less publicized, however, is the fact that a sizable number of people with COVID-19 do not experience symptoms at all. Even the U.S. Centers for Disease Control and Prevention (CDC), in their about-face regarding the usage of masks to slow the spread of COVID-19, stated, "We now know from recent studies that a significant portion of individuals with coronavirus lack symptoms ("asymptomatic") …"1 One of those studies found that in a family of three who had all tested positive, only one — a 35-year-old man — had symptoms. The other two family members, a 33-year-old woman and 3-year-old boy, were asymptomatic.2 Since widespread testing hasn't been done in the U.S., and most of those who have been tested had symptoms, it's largely unknown how many people may have already had, and recovered from, COVID-19 but didn't know it because they didn't have symptoms. The few studies that have been done toward this end, however, are providing revealing data showing that 87.9% of one group that tested positive had no symptoms.
