YOU can get HIV if you have unprotected oral sex, health experts warned this
week, even though the latest study has found no cases of infection resulting
from oral sex.

The study, by Kimberly Page Shafer and her colleagues from the University of
California at San Francisco, is ongoing. So far, the HIV infection rate from
oral sex in the 198 participants is zero, Shafer told the National HIV
Prevention Conference in Atlanta this week.

However, several cases have been reported which suggest that oral sex can
result in HIV transmission, so the latest findings must be interpreted
cautiously, experts say. 鈥淟ow risk is not the same as no risk,鈥� says Ronald
Valdiserri, deputy director of the US National Center for HIV, STD and TB
Prevention. 鈥淲e do know that it is possible to become infected with HIV after
oral sex.鈥�

Shafer herself says the results should be treated with caution and that
infection may occur. 鈥淭he results are based on a relatively small sample,鈥� she
says. In addition, various other sexually transmitted diseases, such as
gonorrhoea, chlamydia and syphilis, are transmitted orally, so there are other
good reasons to refrain from having unprotected oral sex.

The 198 participants, mostly gay males, came from HIV testing and counselling
sites in San Francisco. They had no anal or vaginal sex and did not inject drugs
in the six months prior to the study. On average, each participant has had
roughly two partners with whom they had oral sex, and 98 per cent said it had
been unprotected. Twenty per cent of these encounters were with an HIV-positive
partner.
