Primary HIV infection is the first stage of HIV disease, when the virus first establishes itself in the body. Some researchers use the term acute HIV infection to describe the period of time between when a person is first infected with HIV and when antibodies against the virus are produced by the body (usually 6- 12 weeks).
Some people newly infected with HIV will experience some "flu-like" symptoms. These symptoms, which usually last no more than a few days, might include fevers, chills, night sweats and rashes (not cold-like symptoms). Other people either do not experience "acute infection," or have symptoms so mild that they may not notice them.
Given the general character of the symptoms of acute infection, they can easily have causes other than HIV, such as a flu infection. For example, if you had some risk for HIV a few days ago and are now experiencing flu-like symptoms, it might be possible that HIV is responsible for the symptoms, but it is also possible that you have some other viral infection.

What are the Symptoms of AIDS?
There are no common symptoms for individuals diagnosed with AIDS. When immune system damage is more severe, people may experience opportunistic infections (called opportunistic because they are caused by organisms which cannot induce disease in people with normal immune systems, but take the "opportunity" to flourish in people with HIV). Most of these more severe infections, diseases and symptoms fall under the Centers for Disease Control's definition of full-blown "AIDS." The median time to receive an AIDS diagnosis among those infected with HIV is 7-10 years. (Source: Centers for Disease Control - CDC)
How is HIV Transmitted?
HIV can be transmitted from an infected person to another through:
- Blood (including menstrual blood)
- Semen
- Vaginal secretions
- Breast milk
* Activities That Allow HIV Transmission
- Unprotected sexual contact
- Direct blood contact, including injection drug needles, blood transfusions, accidents in health care settings or certain blood products
- Mother to baby (before or during birth, or through breast milk)
Oral sex (mouth-penis, mouth-vagina): The mouth is an inhospitable environment for HIV (in semen, vaginal fluid or blood), meaning the risk of HIV transmission through the throat, gums, and oral membranes is lower than through vaginal or anal membranes. There are however, documented cases where HIV was transmitted orally, so we can't say that getting HIV-infected semen, vaginal fluid or blood in the mouth is without risk. However, oral sex is considered a low risk practice.
Sharing injection needles: An injection needle can pass blood directly from one person's bloodstream to another. It is a very efficient way to transmit a blood-borne virus. Sharing needles is considered a high-risk practice.
Mother to Child: It is possible for an HIV-infected mother to pass the virus directly before or during birth, or through breast milk. Breast milk contains HIV, and while small amounts of breast milk do not pose significant threat of infection to adults, it is a viable means of transmission to infants.
The following "bodily fluids" are NOT infectious:
- Saliva
- Tears
- Sweat
- Feces
- Urine
Can I get HIV from oral sex?
There is considerable debate within the HIV/AIDS prevention community regarding the risk of transmission of HIV through oral sex. What is currently known is that there is some risk associated with performing oral sex without protection; (there have been a few documented cases of HIV transmission through oral sex). While no one knows exactly what that risk is, cumulative evidence indicates that the risk is less than that of unprotected anal or vaginal sex. The risk from receiving oral sex, for both a man and a woman, is considered to be very low.
Currently, risk reduction options when performing oral sex on a man (fellatio) include the use of latex condoms, but also include withdrawal before ejaculation without a condom (avoiding semen in the mouth) and/or refraining from this activity when cuts or sores are present in the mouth.
When performing oral sex on a woman (cunnilingus), moisture barriers such as a dam (sheet of latex), a cut-open and flattened condom, or household plastic wrap can reduce the risk of exposure to vaginal secretions and/or blood.
If you have other questions about oral sex and HIV, call the CDC National AIDS Hotline at 1-800-342-2437 (English), 1-800-344-7432 (Spanish), or 1-800-243-7889 (TTY). (Source: Centers for Disease Control - CDC)
Can I get HIV from kissing?
Casual contact through closed-mouth or "social" kissing is not a risk for transmission of HIV. Because of the potential for contact with blood during "French" or open-mouth, wet kissing, CDC recommends against engaging in this activity with a person known to be infected. However, the risk of acquiring HIV during open-mouth kissing is believed to be very low. CDC has investigated only one case of HIV infection that may be attributed to contact with blood during open-mouth kissing. In this case both partners had extensive dental problems including gingivitis (inflammation of the gums). It is likely that there was blood present in both partners' mouths making direct blood to blood contact a possibility. (Source: Centers for Disease Control - CDC)
Can I get HIV from casual contact (shaking hands, hugging, using a toilet, drinking from the same glass, or the sneezing and coughing of an infected person)?
No. HIV is not transmitted by day to day contact in the home, the workplace, schools, or social settings. HIV is not transmitted through shaking hands, hugging or a casual kiss. You cannot become infected from a toilet seat, a drinking fountain, a doorknob, dishes, drinking glasses, food, or pets.
HIV is a fragile virus that does not live long outside the body. HIV is not an airborne or food borne virus. HIV is present in the blood, semen or vaginal secretions of an infected person and can be transmitted through unprotected vaginal, oral or anal sex or through sharing injection drug needles. (Source: Centers for Disease Control - CDC)
Can a woman give HIV to a man during vaginal intercourse?
Yes. If the woman is infected, HIV is present in vaginal and cervical secretions (the wetness in a woman's vagina) and can enter the penis through the urethra (the hole at the tip) or through cuts or abrasions on the skin of the penis. The presence of other STDs can increase the risk of transmission. The correct and consistent use of a latex condom or female condom can reduce the risk of transmitting HIV during vaginal intercourse. For more information, call the CDC National AIDS Hotline at 1-800-342-2437 (English), 1-800-344-7432 (Spanish), or 1-800-243-7889 (TTY). (Source: Centers for Disease Control - CDC)
How effective are latex condoms in preventing HIV?
Several studies have demonstrated that latex condoms are highly effective in preventing HIV transmission when used correctly and consistently. These studies looked at uninfected people considered to be at very high risk of infection because they were involved in sexual relationships with HIV-infected persons. The studies found that even with repeated sexual contact, 98-100% of those people who used latex condoms consistently and correctly remained uninfected. For more on these studies, including free written information, call the CDC National AIDS Hotline at 1-800-342-2437 (English), 1-800-344-7432 (Spanish), or 1-800-243-7889 (TTY).

What if I test HIV positive?
If you test positive, the sooner you take steps to protect your health, the better. Early medical treatment, a healthy lifestyle and a positive attitude can help you stay well. Prompt medical care may delay the onset of AIDS and prevent some life-threatening conditions. It is important to know that a positive HIV test should always be confirmed, to be sure that it is a true positive. If your test result is positive, there are a number of important steps you can take immediately to protect your health:
- See a doctor, even if you don't feel sick. Try to find a doctor who has experience treating HIV. There are now many new drugs to treat HIV infection. There are important tests, immunizations and drug treatments that can help you maintain good health. It is never too early to start thinking about treatment possibilities.
- Have a tuberculosis (TB) test done. You may be infected with TB and not know it. Undetected TB can cause serious illness. TB can be treated successfully if detected early.
- Recreational drugs, alcoholic beverages and smoking can weaken your immune system. There are programs available to help you stop.
- Consider joining a support group for people with HIV infection or finding out about other resources available in your area, such as HIV/AIDS-knowledgeable counselors for one on one therapy. There are also many newsletters available for people living with HIV and AIDS.
- There is much you can do to stay healthy. Learning as much as you can is a step in the right direction. Local and/or national resources may be available. Many HIV/AIDS organizations provide services free or on a sliding scale, based on ability to pay.
- Call the CDC National AIDS Hotline for more information and referrals at 1-800-342-2437 (English), 1-800-344-7432, (Spanish), or 1-800-243-7889 (TTY).
How long after a possible exposure should I be tested for HIV??
The time it takes for a person who has been infected with HIV to seroconvert (test positive) for HIV antibodies is commonly called the "Window Period."
The California Office of AIDS, published in 1998, says about the window period: "When a person is infected with the HIV virus, statistics show that 95-97% (perhaps higher) of all infected individuals develop antibodies within 12 weeks (3-months)."
The National CDC has said that in some rare cases, it may take up to six months for one to seroconvert (test positive). At this point the results would be 99.9% accurate.
* What does this mean for you?
The three-month window period is normal for approximately 95% of the population. If you feel any anxiety about relying on the 3-month result, by all means you should have another test at 6 months. (Source: San Francisco AIDS Foundation)
When do you know for sure that you are not infected with HIV?
The tests commonly used to determine HIV infection actually look for antibodies produced by the body to fight HIV. According to the Centers for Disease Control and Prevention (CDC), most people will develop detectable antibodies within 3 months after infection. In rare cases, it can take up to six months. Therefore, the CDC recommends testing at 6 months after the last possible exposure. (unprotected vaginal, anal or oral sex or sharing injecting drug needles). It would be extremely rare to take longer than six months to develop detectable antibodies. It is important, during the six months between exposure and the 6-month test, to protect yourself and others from further exposures to HIV. The CDC National AIDS Hotline can provide more information and referrals to testing sites in your area. The hotline can be reached at 1-800-342-2437 (English), 1-800-344-7432 (Spanish), or 1-800-243-7889 (TTY).

Where can I get tested for HIV infection?
Many places provide testing for HIV infection. It is important to seek testing at a location that also provides counseling about HIV and AIDS. Common locations include local health departments, private physicians, hospitals, and test sites specifically set up for HIV testing.
In addition to traditional testing procedures, there are other options. For those who prefer not to have blood drawn, many sites now offer oral fluids testing, which involves testing of a sample of fluid taken from inside the mouth with a cotton swab. The OraSure Test is currently only available through a health care provider or clinic. Some clinics may also offer urine testing as an alternative to blood tests.
There is also testing which can be performed anonymously in the privacy of your own home. There are many home tests advertised through the internet, but only the Home Access Test has been approved by the FDA. The Home Access test kit can be found at most local pharmacies. The testing procedure involves pricking your finger with a special device, placing a drop of blood on a specially treated card, then mailing the card in for testing. You are given an identification number to use when you phone in for the test results-- 3 days or 2 weeks later, depending on the test kit purchased.
The CDC National AIDS Hotline can answer questions about testing and can refer you to testing sites in your area. The hotline numbers are 1-800-342-2437 (English), 1-800-344-7432, (Spanish), or 1-800-243-7889 (TTY).
