They found previous infection was highly protective against reinfection with alpha, beta and delta variants, but less so against omicron BA.1. To help determine the criteria for patient isolation, we evaluated the duration of shedding of Omicron variant virus isolated from upper respiratory samples collected from the reported case-patients in Japan. According to Chicago-area health departments, people should assume the test results are accurate and should isolate from others to reduce the risk of spreading the virus. People who are moderately or severely immunocompromised should isolate through at least day 20. The experience throughout the pandemic has been reinfection with the same variant (or even "similar" ones, like Alpha -> Delta reinfections) are not common, that infection usually produces a very good immune response, and while immunity wanes, new variants are the main driver of reinfections. Other studies in Europe have also suggested three days is the median incubation period. Omicron has a higher transmission rate and "you don't need four hoursto be exposed.". People with moderate or severe COVID-19 should isolate through at least day 10.
