In Akron Ohio, the city pool was drained because a dead man with AIDS was found in it. The city scrubbed the pool and refilled it. I don't know if the person bled out into the pool or what the situation was, but it was rather odd, with the Health Authorities saying you couldn't get AIDS this way or that way, or whatever, then the City drains the pool...this occurred in the 1990's. People were still phobic about AIDS then and an infected person's life span was much shorter than it is now, with antiviral drugs and all. Maybe the WTBTS didn't want a mutiny of brothers refusing to baptise anyone for fear of contracting AIDS.
Has there been an official update since then? People in general seem to be less afraid of contracting AIDS than they were in the 1980 and 1990s.
