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
HIV can *never survive in any other liquid* medium also other than blood or semen.
Even if one drinks an HIV infected blood (or semen) of someone (ingest through Gastro Intestinal track), the virus *cannot 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 burn your own finger in less than a second if you dip in that acid).
Exposure of less than 1 second in AIR KILLS the HIV virus* (story of needle pricks in Cinema theatres goes down the drain).
Even if blood from a wound (of infected person) dries up (*blood clot*), *the virus dies* and cannot infect anyone else
HIV transmission is *ONLY* an *INFECTION* i.e. entrance of virus in one’s body. It *DOES NOT MEAN AIDS*.
An HIV-infected person (after entrance of virus) can progress to condition of AIDS only after *8 to 10 YEARS *(not in 15 days as in the mentioned story)
It is *not HIV (virus) that kills a human*
The virus attacks immune cells (cells that fight against foreign pathogens/antigens) and hence a person’s ability to fight against infections & diseases slowly diminishes and person ultimately dies of a disease which could be as simple as TB
Most importantly, HIV is no longer dreadful disease … it is “*CHRONIC MANAGEABLE DISEASE *” just like Diabetes or Hypertension. If there is anything you need to be careful from to prevent HIV is *UnsafeSex*, *Blood transfusion* (check before taking) / Blood donation (use sterilized needles only) and any *blood contact during an accident *or so where amount of bleeding is very high.
