If blood splashes into my eye can I become infected with HIV?
Research suggests the risk of HIV infection in this way is extremely small. A very small number of people - usually in a healthcare setting - have become infected with HIV as a result of blood splashes in the eye.
Can I get HIV from a mosquito?
No, it is not possible to get HIV from mosquitoes. When taking blood from someone mosquitoes do not inject blood from any previous person. The only thing that a mosquito injects is saliva, which acts as a lubricant and enables it to feed more efficiently.

Does circumcision protect against HIV?
There is very strong evidence showing that circumcised men are about half as likely as uncircumcised men to acquire HIV through heterosexual sex. However, circumcision does not make a man immune to HIV infection, it just means that it's less likely to happen. Read more about HIV and circumcision.

Male circumcision involves removing the foreskin, a loose fold of skin that covers the head of the penis. Since the 1980s, scientists have suspected that this operation might reduce the chances of HIV transmission during sex. They observed that circumcised men are less likely to have HIV than uncircumcised men, and HIV is less common among populations that traditionally practise male circumcision than in communities where the procedure is rare. However, for a long time it was unclear to what extent this was an effect of circumcision itself, or whether other factors might also play a role.
To settle this issue, three trials were set up in sub-Saharan Africa, which together involved more than eleven thousand previously uncircumcised men. Each man was randomly assigned to one of two categories: one group had their foreskins removed at the start of the study period and the others remained intact. All of the men received extensive counselling on HIV prevention and risk reduction techniques. During the trials, researchers collected information about the men’s sexual behaviour to check whether it varied between the two groups; they found no large differences.
The results of the trials were as follows:
Location Participants Date of initial report Result in circumcised men
South Africa 3,274 July 2005 60% fewer infections 3
Kenya 2,784 December 2006 53% fewer infections 4
Uganda 4,996 December 2006 48% fewer infections 5
Taken together, these findings provide conclusive evidence that male circumcision, if performed safely in a medical environment, roughly halves the risk of a man becoming infected with HIV through heterosexual sex.
There are several possible reasons why circumcision has this effect. The foreskin creates a moist environment in which HIV can survive for longer in contact with the most delicate parts of the penis, and the inner surface of the foreskin contains cells that are especially vulnerable to infection by HIV. If the foreskin is removed then the skin on the head of the penis tends to become tougher and more resistant to infection. In addition, any small tears in the foreskin that occur during sex make it much easier for the virus to enter the body.
It is not clear whether circumcision also reduces the risk of HIV transmission from a man to a woman. A trial to investigate this is ongoing in Uganda.
