What we can definitively say is that by 6 months, more than 99 percent of infected persons will show positive on the antibody tests. Studies looking at the window period for HIV infection generally refer to the average window period, the usual window period, and the maximal window period. This is an average, so not all people will test positive by this point in time. This is as accurate as any test in medicine could ever be. If an infected person gets tested before the 6 month waiting period, the test may show a positive result, a negative result, or it may come up with an indeterminate result.
Prostitution is only legal in licensed brothels, and only in the rural counties.
It is NOT legal in Las Vegas, Reno, Lake Tahoe, Laughlin, and Carson City. Because HIV is a reportable disease in Nevada, if a prostitute were to test positive for HIV, the State Health Division would be notified. However, because of their HIV status, they are prohibited from working in the brothels for life, and have never worked in the legal brothels. We do know however that there are illegal prostitutes who have tested positive for HIV, but these prostitutes are working illegally, and NOT in the licensed brothels. Legal brothel workers are tested for Chlamydia, Gonorrhea, Syphilis, and HIV prior to employment.
