The space all around us contains HIV.
It travels all over the earth with dust.
If it doesn’t please provide evidence of this. All discussions that claim that it cannot travel by air or it “dies” are absurd.
Viruses are not living things and can be blown around easier than dust, they are a billion times lighter.
There is no latching mechanism on them either that would make it so they only attach themselves to humans.
Here is a NASA public domain image of dust all over the Earth.
