Dave, what did Ake do but state that multiple partners was a factor?
He has certainly not stated it was the only factor.

Musket, remember about 22000 people have undiagnosed HIV.
That is what I was referring to.

Instead of me looking up a definition of "epidemic," how about you asking all those public health bodies why they call it an epidemic?
Are you saying that all those health professionals "should know better" like what you do?
