Echoing much of the existing data and research on the subject, SF-based Color released data today showing that based on its own testing program, most individuals who test positive for COVID-19 display either mild or no symptoms, including even running a fever. The results, taken from Color’s own testing of over 30,000 people to date across its California testing stations, shows that despite continuing efforts underway across the U.S. to reopen local and state economies, widespread testing is still key to any true recovery program.

Color notes that 1.3% of the people who it has tested have received positive results for COVID-19, and says that among those, 78% reported only mild symptoms or said they were asymptomatic — meaning they displayed no observable symptoms whatsoever. What’s more, only 12% had a fever  over 100 degrees, which is bad news for efforts to contain potential transmission of cases through measures like temperature checks at workplaces and shared use facilities.
