What we are learning from universities that are opening their campuses for in-person schooling? Are rapid COVID tests as accurate as PCR tests? Can asymptomatic people experience heart and lung damage and other long-term health issues? If only some people are being tested, what does the positivity rate really tell us about community spread? If a student is symptomatic, should the entire class be quarantined? Can trick-or-treating or holiday caroling be done safely this year?
