SARS made people very sick very fast so it was easy to identify and quarantine patients. With extensive contact tracking it was able to be contained.
With covid19 many patients are able to continue their lives and infect others without being obviously sick themselves. This limited the ability to contain outbreaks without extensive testing.
- darkwater 7y agoSo, silly question: why the basic reproduction number R0 doesn't take this into account?
- Mary-Jane 7y agoR0 is what it is, but I agree, it seems like there should be a more meaningful measure that takes factors like incubation period into account.
- watwut 7y agoA lot depends on whether you mean: * R0 when the disease appears first time and people dont know about it * R0 when people learned about disease and changed behavior. Assuming disease is new, one person sick with SARS will infect more people then one person sick with COVID. Due to stronger symptoms and shorter time to symptoms, we learn SARS is issue, change our behavior and quickly close small area. SARS will spread less. In covid, by the time we figure area is infected, a lot of people are infected elsewhere. It takes us more time to react.
- superfx 7y agoDoesn't that mean the effective R0 value for COVID-19 should be higher then?
