Jbog,
It is a different time now and social media is much more widespread. Testing methods may be quicker now so easier to track infections. Besides, that was a variant of influenza whereas this is different. SARS and MERS were more deadly but it appears much harder to spread, which makes COVID-19 more worrisome. Add in the long incubation period and the 14 day or more quarantine is novel and potentially more disruptive to the economy. Even more worrisome is there is an incompetent pathological liar in the Oval Office. You can't trust a single thing he or his administration says and they are trying to control information by not letting Dr. Fauci or other virologists speak on news shows.
