Yeah a billion Chinese are in forced isolation and 4 more countries are close to being cut off from international travel ( including Japan)
And the virus is airborne, as infectious as the common cold, and healthcare can offer no cure, just supportive care
But we must be cautious about calling this a pandemic
It is on every continent. It is pandemic. Due to the fact one can be contagious before symptoms of disease is what makes it most difficult. People have been cleared to travel because they seemed disease free though they were contagious.
This disease will burn itself out over time as past diseases. Once most have been exposed and the vast majority of these will not die we have what is called "herd immunity." If the herd has had the disease and recovered they are immune and no longer a vector for the disease and the disease thus "burns itself out" for lack of vectors.
I hope I am wrong but this disease has the potential of killing 3 percent or more of the world population.
Today those diagnosed die at about 2% with advanced medical care. If this becomes truly pandemic it will overwhelm our medical facilities to give advanced care and thus the death rate will be much higher.
I pray I am wrong.
