Why isn’t HIV airborne like other diseases ? or at least transmit it through saliva ?

Aren’t organisms trying to find the most hosts so it can have more chances to survive ? sure it would kill all its hosts in short time but organisms don’t rationalize like we do, so why won’t it seek to become way more transmissible ?

Evolution favors viruses that will keep its host alive long enough to pass the virus and not necessarily a particular method of transmission. Some viruses live in your mucus (airborne when you sneeze/cough), some in your blood, some in your genital mucosa, some locally on your skin (herpes/hpv).
