Is it true that some people have taken zidovudine (AZT) after an exposure and still become infected?
In the world, there are now less than 20 published cases of health care workers who took antiretroviral drugs after exposure and still got HIV infection. We do not know how many people exposed to HIV initiated ARV therapy and did NOT get infected. Although ARV therapy does not always work, it is still likely to lower the chance of infection.
