IMHO The biggest difference btw this year vs 2009 is Twitter. Sure they had it back then.. but it is no where near the beast it has become today in the global pandemic scenario. Social media platforms have become an extremely powerful tool to form public opinion and to set the course for what is right and what is wrong.. and most importantly.. it provides a shaming platform for those that don't conform.
2009 (US): Deaths: 18,449 (lab-confirmed deaths)... Cases: 1,632,710 (lab confirmed). it is a close second.. and probably a lot closer than those number indicate given the difference in the total overall number of tets that have been performed (mainly as a tool for postmortem analysis).
In otherwords, it was probably very easy to miss a Swine Flu death in 2009... however, you are not gonna miss a Corona Virus death in 2020.
