There have been other global plagues over the centuries. If it is carried in the air, then it will be transmitted by air currents around the planet. There is very little we can do about that.The scariest thing about Coronavirus is that now they're saying that people are getting the virus even if they have not been to China or been exposed to infected people. I have a gut feeling that the virus is spreading much faster and they're not telling us the truth to avoid panic. I'm sure glad I'm a semi-recluse and not having lots of contact with people, like at work or other crowded places.
