There are so many active threads, subthreads, and sub-sub-threads of conversation in the medical community surrounding the COVID-19 pandemic. In this Hippo Education Short, Drs. Tom Robertson and Steve Biederman of Primary Care RAP’s Paper Chase take 4 hot topics in COVID-19 and examine the literature behind them. They look into the epidemiology of the outbreak in the U.S. and lessons learned, the sensitivity and specificity of SARS-CoV-2 testing, the rates of co-infection with other respiratory viruses, and convalescent plasma as a potential therapy.
