@hamster the restrictions, lockdown, mask wearing and social distancing virtually eradicated flu last winter... this is a great way to highlight just how infectious covid is as only the most stringent/all of the above has been able to bring covid case rates down to manageable levels. It's often said that covid is about twice as infectious as flu but the reality is starker than that. This is from a recent guardian article:
Sars-CoV-2 is more infectious than seasonal flu. We’re used to hearing about the reproduction number R, the average number of people whom someone with the virus will infect. In a population without immunity and policies such as social distancing, R for Sars-CoV-2 is now estimated to be around 3. New mutations have raised R further.
In comparison, reproduction numbers for seasonal flu are about 1.3, varying yearly. In the 1918 Spanish flu pandemic, R was higher, at roughly 1.8. That explains why the distancing and other measures being taken, which can bring R for Sars-CoV-2 from 3 to below 1, are enough to almost eliminate seasonal flu.
