According to the
CDC on 3/27:
Much laboratory work continues here at CDC and in a WHO-supported network of laboratories working worldwide, to continue to try to sort out the cause of this illness. The evidence in favor of this illness being caused by a previously unrecognized virus in the group of viruses known as corona viruses continues to mount. I'm not prepared that we're ready to say it's definitive evidence yet. Much work remains to be done. But the preponderance of the evidence as it evolves here and in other laboratories around the world is consistent with a previously unrecognized corona virus playing an important role.

Considering the rate of prescription for antibiotic and immunosuppressant drugs (Prednisone, anyone? Cures whatever ails ya! Just ask your doctor!), along with the overuse of anti-bacterial soaps, it's no wonder viruses are mutating into new resistant strains.
What I'd like to know is what's up in Asia that these killer bugs almost always originate there? I heard someone on the news call this Hong Kong Flu -- which I remember from like 30 years ago or so!
