Thank you both for the replies. The lack of replies was kind of strange, since it seemed like an important issue that was becoming relevant to our daily life in the near future. I did keep in mind that hardly anybody reads or posts in this section of the message board.
The fact that both nurses recovered easily is very encouraging. It appears it's mostly only contagious in the final stage with severe symptoms. It seems like the only way it would become a serious problem here in the U.S. is if a massive amount of people were entering our country and overwhelming the hospitals and CDC, but an occasional traveler here and there does not appear to be much of an issue. If it mutated to a longer incubation period that seems like it could spread through a few individuals, but I'm not a virus expert. The experts do think it's highly unlikely that it would mutate to become fully airborne like the flu or cold.
