Can You Catch Hiv from Oral Sex?

The virus responsible for HIV or acquired human immunodeficiency syndrome is part of the retrovirus family and contains two sub-categories: HIV-1 and HIV-2.

According to statistics, the World Health Organization reported that in 2008, 33.4 million people were known to be infected, of which 15.7 million were female, and 2.1 million were young people under the age of 15.

When the virus enters into the body, it will attack a cell of the essential immune system that is known by the name of lymphocyte giving rise to the disease.

Forms of HIV Transmission

This disease is transmitted frequently and in three significant ways:

  • Through sexual contact, this being what gave it the name of the sexually transmitted disease.
  • This the blood during transfusions.
  • During childbirth, during pregnancy, and lactation.

As regards transmission by blood, this can also be transmitted by the sharing of syringes between infected and non-infected persons or by their re-use.

HIV Risk Factors

About sexual contact, any sex, such as oral, vaginal and anal sex can be a dangerous practice.

Factors such as: may permit transmission of this potential virus upon sexual contact

  • A vaginal or anal penetration without a condom.
  • Its presence of other sexually transmitted diseases, especially those that cause the appearance of genital wounds.
  • Injuries caused by intercourse.
  • It is a large number of sexual partners and unprotected sex.
  • Its presence of a high viral load in a person who has sex.
  • The presence of hemorrhoids.
  • Injection drug use.
  • Lack of knowledge.

Oral Sex and HIV

Oral sex is a sexual activity practiced by the sexual partners and where the stimuli of the genitals occur with the mouth or the tongue. When a woman makes it to a man, it is called fellatio, and when a man makes it to a woman, it is called cunnilingus.

During this practice, there may be the ingestion or absorption of semen or vaginal secretion. In this way, the risk of transmission of HIV or other infectious causes, such as human papillomavirus, may occur.

It can be stated that any contact of the mucosa with mucosa irrespective of any, there is a danger of HIV infection if the sexual secretion is present, such as the vaginal fluid, the sperm or the liquid that precedes the sperm.

Faced with this fact the transmission of this virus also happens through oral sex and not only when people have mouth sores as it was thought for many years. This transmission occurs because the mucous membranes have a high capacity of absorption.

For such infection not to be transmitted through oral sex, it is best to practice safe sex with the use of condoms, which in the case of oral sex is sometimes not very practical, but it is vital.


If HIV infection is so omnipresent, is it essential to completely give up sex? Of course, there is no need for such radical decisions. HIV prevention comes down to one thing – a conscious approach to sexuality. To avoid HIV, you need to follow simple rules:

  • Do not allow casual sexual intercourse; you can not remain entirely sure in the absence of genital infections in a random partner.
  • Always use condoms during any sex. Remember that even your regular partner may not also be aware of their HIV-positive status.
  • To enhance the sensations with oral sex, use thin and flavored condoms, as well as individual latex wipes for cunnilingus.
  • Do not practice oral sex in the presence of bleeding and sores in the mouth.

If you follow these rules, the risk of infection is reduced to nothing. Remember that a conscious approach to sex – is the key to your health.

Risk of contracting other infections

Other STDs that can be transmitted through oral sex include syphilis, herpes, gonorrhea, and chlamydia. With the practice of anilingus can also spread hepatitis A and B, intestinal parasites (such as Giardia ) and bacteria (such as E. coli).

Reduce the risk

People can further reduce the already low risk of HIV transmission during oral sex by preventing their male sexual partners from ejaculating in their mouths. It can be achieved by removing the mouth from the penis before ejaculation or by using a condom.

The use of a barrier during oral sex (such as a condom or a dental dam) can further reduce the risk of transmitting HIV, other STDs, and hepatitis. Dental dikes are square, thin sheets of latex or silicone that are placed over the vagina or anus during oral sex. Latex condoms can also be used as dental dikes by cutting them lengthwise.

The risk of HIV transmission through oral sex is even lower if the partner who is HIV negative takes medication to prevent HIV (pre-exposure prophylaxis or PrEP) or if the HIV-positive partner takes medication to treat HIV ( antiretroviral therapy or ART) and has viral inhibition.
