So far.
So far we don’t even know how Miss Pham contracted.
Yes so far.
People do not realize how uninformed science is about this disease.
It was discovered in the mid seventies. The outbreaks have been pretty sparse, until now.
There are a lot of things, like the dog issue, that the scientists just don’t know.
It is such a horrible disease to get that they (the scientists) don’t do a lot of experimentation on it. Its just too risky.
