HIV man claims 300 sexual partners

A man who told US authorities he had sexual contact with as many 300 people after being diagnosed with HIV has pleaded not guilty to infecting another man with the virus, and prosecutors said more charges are expected.

David Mangum entered the plea after being charged with recklessly infecting another with HIV, which in Missouri – where penalties for such crimes are among the nation’s harshest – carries a maximum sentence of life in prison.
