Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

We anticipate that SARS-CoV-2 will then circulate seasonally with winter peaks in subsequent years
...
Treatments or vaccines for SARS-CoV-2 would reduce the duration and intensity of social
distancing required to maintain control of the epidemic. Treatments could reduce the proportion
of infections that require critical care and could reduce the duration of infectiousness, which
would both directly and indirectly (through a reduction in R0) reduce the demand for critical care
resources. A vaccine would accelerate the accumulation of immunity in the population, reducing
the overall length of the epidemic and averting infections that might have resulted in a need for
critical care. Still, the development and widespread adoption of pharmaceutical interventions will
take months at best, so a period of sustained or intermittent social distancing will almost
certainly be necessary.

New therapeutics, vaccines, or other interventions such as aggressive contact tracing and quarantine – impractical now in many places but more practical once case numbers have been reduced and testing scaled up (20) – could alleviate the need for stringent social distancing to maintain control of the epidemic. In the absence of such interventions, surveillance and intermittent distancing may need to be maintained into 2022, which would present a substantial social and economic burden.
