there are periodic ob's of hiv in the porn industry. when that occurs, they don't allow anyone who's been with that person or anyone who was with someone that person was with to be in films until enough time has passed for full and more accurate testing.
any particular reason for your question?

Thanks for your answer! But what if HIV developes in less than 28 days?
I have read that before engaging in uprotected sex you should do the test and 3 moths after another one and no barebacking in the meantime.
Most pornstars do contracted the most common stds in the industry but they do get tested every month for HIV and other serious stds. A standard antibody tested at 28 days or more is effective in detecting 85-90% of antibodies but they also use PCR RNA testing as well although it may not be reliable at time. Before a shoot, they always make sure the performers are checked and screened.
