Emily Oster, an economics professor at Brown University, and Galit Alter, a professor of medicine at Harvard Medical School, created a database of COVID-19 cases from selectively reporting child-care facilities and summer camps at their website, Covid Explained.

All you will read about are asymptomatic cases, sore throats, and mild fevers.
According to the CDC, out of the 260 who tested positive, 136 cases had available documented symptom data.
Among them 26% reported no symptoms, while 74% did report symptoms but "those most commonly reported were subjective or documented fever (65%), headache (61%), and sore throat (46%)."
