The SARS-CoV-2 virus is likely from a zoonotic source. Transmissibility between humans occurs primarily through droplets and surface contacts. Persons with the virus may shed it while symptomatic or asymptomatic. Although incubation period is up to 12 days, median duration of viral shedding can be up to 20 days. Clinical symptoms vary widely and may be mild (80%), moderate (15%), or severe (5%).
