these r some important things about HIV * HIV (virus) requires *ONLY* *Blood or Semen* as medium to transmit from one body to another * HIV *can not* transmit even through *Saliva* (mucous) i.e. even if HIV-infected patient coughs or smooches and another person is exposed to his sputum (cough) or saliva, the virus still can not transmit because concentration of virus particles in sputum is almost NIL & exposure to air anyway kills virus in fraction of seconds * In case HIV-infected person got an injury (like the cut in below mentioned story) and he is bleeding, the virus can transmit to another person only if another person has a cut/wound in his body & that too when *blood from both person comes in contact with each other* (this is also very very rare unless bleeding is very high) and not otherwise * HIV can *never survive in any other liquid* medium also other than blood or semen (& please for God sake ... never in Pani Puri wala pani) * Even if one drinks an HIV infected blood (or semen) of someone (ingest through Gastro Intestinal track), the virus *can not survive in the acidic pH of stomach*. Highest extent of acidity is 0 (practically not possible) so imagine 1 as pH which is in our stomach. (This pH can bun your own finger in less than a second if you dip in that acid). so spread this message & remove t fear among th people.
