What I understand: - This author has a lot of alarmist material... and this one's warranted. :I - H5N1 is the avian flu that is an analog for past disease spread, but not related to Coronavirus. Both H5N1 and Coronavirus are spread first through animals - much like Swine Flu (H1N1), Ebola, and Zika (latter two esp. through bugs). - MERS and SARS are related to Coronavirus. The strain we are hearing about on the news is COVID-19. What I don't understand: - So what is SARS-CoV-2? Is that even MORE specific to the strain on the news?And coronaviruses could present a particular challenge in that at their core they are, like influenza viruses, a single strand of RNA. This viral class is likely to mutate, and vaccines may need to be in constant development, as with the flu.
