I don't like how these virus's aren't contained sooner, before it becomes a worldwide problem. The minute they seen people getting sick, they should have been quarantined immediately to find out just what they had. Then shut down travel...……...if they had, that flu never would have made it out of China and thousands would have been saved from catching & spreading it further. IMHO
I think your point about these viruses should be contained sooner is very interesting. Is it POSSIBLE? I mean, for some weeks, a few people get a pneumonia they shouldn't be getting, maybe, but that does happen. Finally, somebody looks at it under a microscope and YOW! it's a new one. In the meantime, the virus is travelling fast.
I guess I don't think we can stop new diseases, because we don't perceive them soon enough. But it's a good point for sure about known diseases, like the Ebola outbreak last summer. They got right in there, and it seems to be stopped. A terrible disease such as sm*llp*x (never say the Devils name or he comes) should be watched for and moved on fast. Polio. Maybe not cholera, as that's limited to a locale (the water). Typhoid.
