Question:

Answer: 

Hello,

Thank you for your inquiry. From what we gather from the question, you were asking about the risk of acquiring HIV from receiving oral sex. From the information given, this scenario is determined to be of Negligible Risk (There are no evidence or no documented cases of transmission. However, there is a theoretical possibility of transmission under certain extenuating circumstances).

Although saliva can contain trace amounts of HIV, there is not enough of the virus for sufficient transmission. Saliva contains enzymes that breakdown the virus within the mouth, thus is a protective factor against HIV. The risk of HIV transmission through oral sex is extremely low, several factors may increase that risk, including sores in the mouth or vagina or on the penis, bleeding gums, oral contact with menstrual blood, and the presence of other sexually transmitted diseases (STDs). However, using a barrier like a condom or dental dam during oral sex can further reduce the risk of transmitting HIV, and other STDs.

In regard to your concern about the incubation period for HIV from your partners previous partner. Signs and symptoms of seroconversion appear to occur from between 40-60 days after transmission has taken place (1). Yet, seroconversion has known to occur starting at two weeks after HIV transmission has taken place. During this incubation period, HIV is characterized by the high viral load in the body of the newly positive individual, making HIV highly transmittable.

In the scenario you have provided above, there appears to be less than a 10 day incubation period in which the theoretical presence of HIV would have little time to increase the viral load to highly infectious levels.

For these reasons, this scenario is determined to be of Negligible Risk to you.

Recommendation: There is no evidence or documented cases of transmission. Refer to a healthcare professional for more personalized answers.
