Good point RustyJ....
Klein is still confusing people with his responses. He seems to suggest that the 3-7% have somehow shaken off the disease - 'they have signs of prior infection'. Wrong! They have signs of current infection. A retrovirus does not leave the body. Those people are a walking time bomb. His confusing message seems to deliberately mask this message. Is this part of the campaign to minimise any public alarm? Clumsy attempt if it is.
