Facts about ?HIV?

HIV (virus) requires *ONLY* *Blood or Semen* as medium to transmit from one body to another

HIV *cannot* transmit even through *Saliva* (mucous) i.e. even if HIV-infected patient coughs and another person is exposed to his sputum (cough), the virus still cannot 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 rare unless bleeding is very high) and not otherwise
