Further, a protocol compliant patient who has sex with thousands of men cannot get 'new' HIV or extra HIV or become infectious. If the person is less than three months poz, a new strain can supplant the original that is drug resistant there are two cases of this. After that, any new virus is immediately inhibited by the meds and attacked by the immune system. Injection drugs don't give you HIV either when you have it already. Non compliance can cause viral load to spike. Party lifestyle is not necessarily supportive of compliance but its important to say drug addicts are good at taking drugs. If a person is undetectable they cannot transmit. HIV is being spread by people who don't know their status. Not poz folks on meds.
