That is all true - but only if the person with HIV (measures as HIV+) has a detectable viral load (different test). Properly treated HIV get the viral load down to become undetectable - the correctly treated person is no longer infectious. At the same time, getting treated always means the person also gets much more aware of the need for adherence to the regime of daily pills, and living a healthier lifestyle. Kisses, scratches, condoms etc are not important. Testing <<<<, treating and having an undetectable viral load are the key here.
