Paxlovid Is Super Promising. One review of studies concluded that the odds of indoor transmission is almost 19 times higher than outdoor transmission. Index patients and household contacts participated in voluntary telephone interviews to retrospectively collect information on demographic characteristics, SARS-CoV-2 testing, symptoms, COVID-19 vaccination history, previous SARS-CoV-2 infection, index patient isolation practices (defined as always or sometimes isolating in a room by oneself at any point during their potentially infectious period), and index patient mask use practices (defined as ever wearing a mask at home during their potentially infectious period). . 1.
