This is a great outline of how the outbreak could end (from best to worst-case scenario): 1. Public health interventions control the 2019 n-CoV 2. The virus burns itself out (I love this analogy of viruses to fires) like the Spanish flu 3. It becomes a common virus like ex-pandemic H1N1 (swine) flu.
The World Health Organization has declared the growing coronavirus outbreak in China to be a global health emergency. It’s a recognition that the outbreak — now with nearly 10,000 cases — may continue to spread beyond China, and that the nations of the world should lend their assistance and be prepared.
