FAQs About HIV Transmission
Q: What bodily fluids transmit HIV from one person to another?
A: HIV is transmitted through blood, semen, pre-semen (pre-ejaculate), vaginal fluids, and breast milk. These fluids need to enter the bloodstream. Saliva is not generally considered risky, but cuts, sores, or blisters in the mouth increase the likelihood of transmission (i.e., HIV infection). Other bodily fluids such as sweat, tears, or urine are not risky.

Q: If I'm negative and my partner is negative, do we need to practice safer sex?
A: If both partners are truly HIV negative, there is no risk for HIV transmission. However, other sexually transmitted diseases should be considered such as herpes, venereal warts (HPV), gonorrhea, chlamydia, and syphilis. The issue of trust needs to be carefully addressed and discussed if a decision to not use condoms is being considered.

Q: If I'm positive and my partner is positive, do we need to practice safer sex?
A: Researchers are concerned that re-infection with HIV may be possible and could cause the disease to progress more rapidly. Also, there is a possibility that a virus that is resistant to certain medications can be transmitted to another person with HIV, which means future treatment options may be limited.

Q: Do all condoms prevent the spread of HIV?
A: Condoms made from latex or polyurethane, when used correctly, can prevent transmission of HIV, other sexually transmitted diseases, and pregnancy. Female condoms are available as well as the more common ones for men. Condoms made from animal skin, such as sheepskin, have tiny pores (holes) and are not good protection against HIV and other sexually transmitted diseases. When condoms fail, it is usually from human error. Be sure to squeeze the tip before putting the condom on a fully erect penis, and roll the condom completely on. Water-based lubricants help to prevent breakage. Oil-based lubricants, such as petroleum jelly and hand lotion, can cause condoms to break.

Q: Am I at risk if I have anal sex and I'm the insertive partner (top)?
A: Although the receptive partner (bottom) is at greater risk of acquiring HIV, the virus can also be transmitted to the insertive partner (top). HIV can enter through the urethra, if blood is transmitted from the anus. HIV transmission is also more likely if either partner has already contracted another sexually transmitted disease.

Q: I'm negative and my partner is positive, but has an undetectable viral load. Do we need to use condoms?
A: Having an undetectable viral load (amount of virus in the blood) probably decreases the risk of transmission. However, measurable amounts of virus may be in semen or vaginal secretions. There is still a risk if condoms are not used.

Q: Am I at risk if I am heterosexual?
A: For several years, the numbers of heterosexuals acquiring HIV through sex has been increasing. HIV can be transmitted from a man to a woman and vice versa. Latex condoms can prevent the spread of HIV.

Q: Is oral sex risky?
Oral sex is considered "low-risk", but it is not risk free. Oral sex is less risky than anal or vaginal intercourse. Research on oral transmission of HIV is limited. Many anecdotal cases, and some documented cases, have been reported from people who most likely acquired HIV through oral sex. The person receiving oral sex (the person not using his or her mouth) is at minimal risk with this activity.

Here are some things to keep in mind:

  • HIV is transmitted through bodily fluids. If semen or vaginal secretions are transmitted, there is some degree of risk of acquiring HIV.
  • A higher viral load probably increases the likelihood of transmission.
  • Condoms, dental dams, and avoiding the 'head' of the penis will prevent transmission.
  • Cuts, sores, and blisters in the mouth increase the likelihood of transmission.

Q: Is kissing risky?
Kissing does not pose a risk of acquiring HIV. However, it is generally good practice to avoid deep kissing if either partner has cuts, sores, or blisters in the mouth.

Q: Aren't the treatments today good? Do I really have anything to worry about?
A: It is true that research has come a long way and HIV medications have increased the quality and length of life for people living with HIV. That doesn't mean living with HIV is easy. Here are some things you may not realize:

  • HIV medications have side effects, ranging from chronic nuisances to more serious conditions, such as pancreatitis and fat abnormalities.
  • Dosing schedules are usually complicated and often require unwanted lifestyle changes. At present, these drugs need to be taken for life.
  • Most of the medications available today have only been approved since about 1995. We do not know the longer-term effects of these medications.
  • The number of different medications are limited. Many people are currently resistant to the drugs. People are still getting sick and dying from AIDS.
  • Consider disclosure. How would you deal with telling your family and friends? How would this disease affect your relationships, dating, and sex?
  • IT IS BETTER TO STAY UNINFECTED!

Q: Besides sex, what are other ways that HIV is transmitted?
A: HIV is also transmitted through needle sharing and perinatally (from mother to baby). Accidental needle sticks account for a small number of HIV cases. Blood transfusions are no longer a threat since screening for HIV is routine. Casual contact, drinking fountains, swimming pools, and insect bites do not transmit HIV.

Q: Where can I go for more information about HIV transmission and prevention?
The AIDS Foundation San Francisco has a great Web site with information on HIV transmission, safer sex, and prevention. Check it out.
