We now believe that incubation period for the SARS-CoV-2 virus varies from person to person between 1-14 days1, and that many individuals have asymptomatic or very mild infections2. We have preliminary estimates for how long someone is infectious3, but it’s still too early to say what the average incubation period is (as with most diseases, there’s a range). Let’s assume everyone infected with this virus is infectious for 10 days, starting three days before they show any symptoms. 4) Explain what would happen to the R0 value in the following three situations (You may want to use numbers to work through your explanation, based on the 1-14 day incubation and the 10-day infectious period)
a. Every single person on the planet stayed home for 10 days.
b. Every single person on the planet stayed home for 30 days.
c. Every single person on the planet went back to their normal life immediately.
