HIV infection is not transmitted by
1. giving blood by using disposable instruments
2. using toilets and urinals used by infected persons
3. travelling in the same taxi,auto or bus
4. shaking hands with infected persons
- only (1) and (2) are correct
- only (4) is correct
- All of the above are incorrect
- All of the above are correct
Option 2 is the right answer.
The HIV virus cannot be transmitted by casual contact, from a toilet seat, a doorknob, a fork, or a handshake, for that matter. The only known HIV transmission methods include unprotected sex, intravenous drug use, exposure to blood or bodily fluids from an infected person, from mother to child in pregnancy, and through blood transfusions if the blood came from an HIV infected person. Transmission of the virus did happen through blood transfusions or blood products in the 1980s before HIV testing became routine for all donated blood, but is highly unlikely to happen in a modern medical facility.
