Virus Mythbusting
You CAN'T get AIDS from:
1. Kissing
At the moment, scientific opinion is pretty clear that you cannot become infected with HIV through kissing.
To become infected with HIV you must get a sufficient quantity of HIV into the bloodstream. Saliva does contain HIV, but the virus is only present in very small quantities and as such, cannot cause HIV infection.
Unless both partners have large open sores in their mouths, or severely bleeding gums, there is no transmission risk from mouth-to-mouth kissing.
2. Sneezing, coughing, sharing cups/glasses, or toilet seats
HIV is unable to reproduce outside its living host, except under very extreme laboratory conditions. HIV does not survive well in the open air, and this makes the possibility of this type of environmental transmission remote. In practice no environmental transmission has been seen.
This means that HIV cannot be transmitted through spitting, sneezing, sharing glasses or musical instruments.
You also can't be infected in swimming pools, showers or by sharing washing machines or toilet seats.
3. Insect bites
Studies conducted by many researchers have shown no evidence of HIV transmission through insects, even in areas where there are many cases of AIDS and large populations of insects such as mosquitoes. Lack of such outbreaks, despite considerable efforts to detect them, supports the conclusion that HIV is not transmitted by insects.
Also, HIV only lives for a short time and does not reproduce in an insect. So, even if the virus enters a mosquito or another sucking orbiting insect, the insect does not become infected and therefore cannot transmit HIV to the next human it feeds on or bites.
4. Injecting with sterile needles
Drug use with sterile works will not transmit HIV either, as long as clean works are used every time - this means needle, syringe and spoon,water and filters. There are still many other risks associated with injecting drug use. And, if you are on drugs, even alcohol, this may cloud your judgment and make you more likely to become involved in risky sexual behaviour - it's harder to make the effort to use a condom when you're off your head.
5. Protected Sex
Condoms, if used correctly and consistently, are highly effective at preventing HIV transmission. There are myths saying that 'some very small viruses can pass through latex' - this is not true.
Anal sex is not necessarily a risk if unbroken condoms are used and there is no blood-to-blood contact. You can't 'create' HIV by having anal sex.
