Document: Contact tracing has identified asymptomatic infections, but studies of their frequency and transmissibility have been limited. Many of those infected are health care workers in whom these questions could be systematically studied. Relatively little is known about the natural history of human asymptomatic infections. Further studies of virus shedding, seroconversion, and transmission in asymptomatic infections are needed. Some evidence suggests that secondary cases have lower average CFRs and that subsequent links in the chain of MERS-CoV infection may decrease in severity.
