HIV can not spread in a river

Even if an infected person had a cut, the blood in the pool water wouldn’t last long and therefore would not cause you to become infected with the virus.

The virus is unable to survive in pool water and is therefore there have been no reported cases of HIV transmission from pools or hot tubs or rivers.

Chlorine instantly kills any virus (HIV, Ebola, Rhino…) that it contacts, in addition to the fact that these viruses cannot survive outside of the human body.
