What We Know About Anal Sex
Anal sex is the riskiest type of sex for getting or transmitting HIV. Although receptive anal sex is much riskier for getting HIV than insertive anal sex, its possible for either partnerthe insertive or receptiveto get HIV.
An HIV-negative receptive partners risk of getting HIV is very high because the lining of the rectum is thin. HIV can enter the body through this lining during anal sex from body fluids that carry HIV, including semen or pre-seminal fluid .
On average, an HIV-negative receptive partner has about a 1 in 70 chance of getting HIV every time they have receptive anal sex with a partner who has HIV.
Being the receptive partner for anal sex is about 13 times more risky for getting HIV from a partner with HIV than being the insertive partner.
For women, anal sex is about 17 times more risky for getting HIV from a man with HIV than vaginal sex.
If the partner with HIV takes HIV medicine as prescribed, and gets and keeps an undetectable viral load , you have effectively no risk of getting HIV through sex with that partner.
An HIV-negative insertive partner is also at risk because HIV can enter the body through the opening at the tip of the penis the foreskin if the penis isnt circumcised or small cuts, scratches, or open sores anywhere on the penis. There is some evidence that circumcision decreases a mans risk of getting HIV during sex.
How Long Does Hiv Live Outside The Body In Blood
HIV in blood from something like a cut or nosebleed can be active for several days, even in dried blood. The amount of virus is small, though, and unable to easily transmit infection.
HIV survival time in fluid outside of the body can increase when a small amount is left in a syringe. After an injection in someone with high levels of HIV, enough blood stays in the syringe to transmit the virus. Since its inside a syringe, the blood isnt as exposed to air as it is on other surfaces.
According to the , when the temperature and other conditions are just right, HIV can live as long as 42 days in a syringe, but this typically involves refrigeration.
HIV lives the longest in a syringe at room temperature, but can still live up to
Can I Transmit Hiv To My Baby During Pregnancy Or Breastfeeding
An HIV-infected pregnant woman can pass the virus on to her unborn baby either before or during birth. HIV can also be passed on during breastfeeding. If a woman knows that she is infected with HIV, there are drugs she can take to greatly reduce the chances of her child becoming infected. Other ways to lower the risk include choosing to have a caesarean section delivery and not breastfeeding.

Blood Transfusions And Organ Donation
The risk of contracting HIV from a blood transfusion, other blood products, or organ donation is now extremely rare in the United States. All donated blood or blood products in the United States are for several types of bloodborne pathogens, including HIV.
Organ donations are also screened for HIV. Although very rare, its possible for HIV transmission to occur following an organ transplant.
However, testing of organ recipients after surgery can quickly detect transmission so that antiretroviral medications can be started promptly.
Other Health Problems That Affect Periods
- A missed period might mean that you are pregnant or that you are starting to go through the menopause.
- Abnormal bleeding or very heavy periods could be signs of a health problem and should always be reported to your doctor.
- Heavy periods can be caused by several factors, including fibroids . If left untreated, the blood loss from heavy periods could lead to anaemia .

Hiv Testing Outside Of A Health Care Setting Or Lab
If you are tested outside of a health care setting or lab you will likely receive a rapid HIV test
- If the test comes back negative, and you havent had a possible exposure during the previous 3 months, you can be confident you dont have HIV.
- If your test result is positive, you should go to a health care provider to get follow-up testing. Counselors providing the test should be able to answer questions and provide referrals for follow-up testing as well. You can use the HIV.gov locator to find a provider near you.
What Is Hiv And What Is Aids
HIV/AIDS are widely known as incurable sexually transmitted diseases, but you might not know the difference between these acronyms and what they stand for.
For simplicityâs sake, HIV is the virus that causes AIDS. HIV stands for the Human Immunodeficiency Virus.
If a person takes a blood test and receives a diagnosis of HIV, then they are HIV positiveâif a person does not have HIV, then they are HIV negative. HIV causes havoc in a personâs body by weakening their immune system . HIV progressively destroys the cellular part of the immune systemâparticularly types of white blood cells called CD4 cellsâwhich, over time, makes the person become immunodeficient .
As the HIV infection develops in the body, the person will become more and more immunodeficient until they reach a point where they are classified as having Acquired Immunodeficiency Syndrome . This is often the end stage of an HIV infection, where a personâs body is so immunodeficient that they develop infections, diseases, or cancers and are no longer able to mount a immune defense and fight them off .
There is no cure for HIV . But, if a person does become infected with HIV there are treatments available which can help keep a person healthy.

Hiv Testing Types And Lab Technologies
This chapter provides information regarding available testing technologies, approaches to testing and interpretation of results. There are many different types of HIV screening tests that are licensed for use in Canada and can vary by jurisdiction. For questions or information specific to your province or territory please contact your local Public Health laboratory.
Is There Any Treatment Of A Cure For Hiv/aids
Currently, there is no cure for HIV/AIDS. People living with HIV will need lifelong treatment. The best treatments right now are combinations of prescription drugs. These medications include antiviral treatment, protease inhibitors and other drugs that help people who are living with HIV stay healthy. People living with HIV also can stay healthy by doing things like eating properly, exercising and getting enough sleep.

While research suggests that high concentrations of HIV can sometimes be detected in precum, it is difficult to judge whether HIV is present in sufficient quantities for infection to occur. To guard against the possibility of infection with HIV or any other STI it is best to practice safer sex by using condoms.

Can Hiv Be Transmitted Via Contact With Menstrual Blood
Menstrual blood touching intact skin poses no HIV transmission risk. If it comes into contact with broken skin or is swallowed, then HIV transmission is possible but still unlikely. Due to the effectiveness of HIV treatment, the menstrual blood of someone living with HIV who is adherent to their antiretroviral medication could well have no detectable virus . The small number of case reports documenting HIV transmission via exposure to blood involved a significant amount of blood from the HIV-positive person, as well as open wounds in the other persons skin.
Are Women At Greater Risk Of Hiv During Menstruation
The menstrual bleeding during a period itself does not increase the risk of acquiring HIV. However, hormonal changes during menstrual cycles are believed to place women at greater risk than at other times. The biology of the vagina and cervix mean that women, especially adolescents and older women, are in general more vulnerable to HIV and sexually transmitted infections than men.
A 2015 study in monkeys concluded that immune protection is at its lowest mid-cycle, providing a window of opportunity for infections to enter. In addition, researchers following a group of 37 HIV-negative female sex workers in Nairobi, Kenya found an association between the first stage of the menstrual cycle and factors that could mean increased susceptibility to HIV infection. The authors concluded that a better understanding of the natural hormonal cycle on the vaginal immune environment is required to identify exactly how it influences HIV sexual transmission in women.
Since more research is needed to establish clarity on when women are most at risk, women should always consider using barrier methods such as male and female condoms to provide the best protection from STIs including HIV, regardless of the stage of their menstrual cycle.

A Word About Window Periods
The window period refers to the time it takes for HIV to show up in an HIV test. The length of the window period will depend on the type of test you take.
If you feel like you may be at risk of HIV, do not wait, speak to a healthcare professional as soon as possible. The most important thing is to test.
If you test negative but think you may have been exposed to HIV more recently, you can take another test once the window period has passed.
The picture below shows the window periods for different HIV tests. Some tests can give you an accurate result within four weeks, while others can take three months to be accurate .
A healthcare worker will be able to explain how long the window period is for the test you are taking, and will tell you if they think youll need to test for HIV again.
Hiv Is Detected With A Blood Test
Blood tests are the most common and reliable tests for HIV. The virus is detected by taking a sample of your blood either with a conventional blood test or a rapid test .There is a short period of time between exposure to HIV and the ability for tests to detect HIV or its antibodies. This is often referred to as the ‘window period’ between 2 and 12 weeks.
Most tests used in Australia can detect HIV as early as 2 to 4 weeks after infection.
If your blood test shows that HIV or its antibodies are present, you are HIV-positive.
If you have no antibodies in your blood you are HIV-negative. Sometimes negative results might also mean you are in the window period, so you might need a follow-up blood test to make sure.

Can Hiv Be Transmitted Through Oral Sex
Yes, but the risk is relatively low.
HIV is transmitted through seminal and vaginal fluids, including menstrual fluids. The virus can enter the body through the bloodstream or by passing through delicate mucous membranes, such as inside the vagina, rectum or urethra.
If a person gives fellatio and has bleeding gums, a cut, or an ulcer inside their mouth, HIV could enter their bloodstream through infected fluid. This could also happen if infected fluid from a woman gets into the mouth of her partner during oral sex.
Using a condom during sex, including oral and anal sex, is the best way to prevent sexually transmitted infections , including HIV. Avoid using an oil-based lubricant, such as Vaseline or baby oil, because they can weaken the condom and increase the risk of it splitting.
You can use a dental dam to cover the anus or female genitals during oral sex. A dental dam is a latex or polyurethane square, measuring about 15cm by 15cm. It acts as a barrier to help stop STIs passing from one person to another.
How You Become Infected
There is HIV virus in body fluids like vaginal secretions and semen. If those fluids are present, they can enter the bloodstream of someone who doesn’t have HIV through an opening such as a mouth sore or a genital ulcer.
Your chances are higher of getting HIV if you:

Challenges In Hiv Testing
4.3.1 HIV Testing in the “window period”
The window period is the time after acquisition of HIV infection when the individual is highly infectious but tests negative on HIV antibody screening because antibodies are not immediately produced. As shown in Figure 4, the timelines associated with the window period have changed with the evolution of more sensitive antibody screening tests. While 1st generation tests detected HIV antibody an average of 60 days following exposure the 4th generation combination tests permit detection of acute HIV infection during the viremic phase. This reduces the window period to approximately 15 to 20 days. Making the diagnosis as early as possible can help prevent onward transmission of the virus, since the person is most infectious during this period. Some jurisdictions provide NAAT testing for high-risk clients , in an effort to identify very early HIV infection.
4.3.2 Indeterminate results during the window period
4.3.3 Confirmatory Testing
The Western Blot assay is not as sensitive as the 3rd and 4th generation screening tests and may yield indeterminate results during the window period. New algorithms employing NAAT as a confirmatory test are currently being evaluated.

Figure 5 is a detailed diagram showing the days elapsed, from zero to 360, since the start of HIV infection. The diagram is divided into a sliding scale of four time periods:

Myths About Period Sex
Having sex during your partners menstrual period may not be your cup of tea, but then if youve never tried it, how would you know? There are countless religious and cultural taboos that forbid intercourse during that time of the month and youll have to make up your own mind about exactly how you feel about those. But there are also some pretty silly misconception and myths about period sex, especially among guys, that need to be cleared up.
1. Its gross
Look, theres no doubt that period sex has the potential of being a fair bit more messy than sex during the rest of the month, but with a little planning its not gross at all. A towel or an extra sheet spread on your bed will do a discreet mop-up job if necessary. Alternatively, why not do the deed in the shower or the bath tub. Theres nothing like a change of scenery to keep things interesting and any messiness is easily washed away at the turn of a tab.
As another option, you partner may want to try wearing a diaphragm, or a menstrual cap shaped like one, or even a female condom all of which will capture any blood while allowing penetration. If you use a dental dam even oral sex during her period doesnt have to freak you out some guys actually develop a particular, erm… taste for it.
2. Its unhealthy
3. You cant get AIDS or STDs
4. It wont be fun
5. She cant fall pregnant
6. Itll make her period worse

What We Know About Oral Sex
The chance an HIV-negative person will get HIV from oral sex with an HIV-positive partner is extremely low. However, its hard to know the exact risk because a lot of people who have oral sex also have anal or vaginal sex. The risk is even lower if the HIV-negative partner is taking medicine to prevent HIV . If the partner with HIV is taking HIV medicine as prescribed and keeps an undetectable viral load , they have effectively no risk of transmitting HIV through sex, including oral sex.
But you can get other sexually transmitted diseases from oral sex. And, if you get feces in your mouth during anilingus, you can get hepatitis A and B, parasites like Giardia, and other bacteria like Shigella, Salmonella, Campylobacter, and E. coli.
Is Unprotected Anal Intercourse More Of An Hiv Risk Than Vaginal Or Oral Sex
Unprotected anal intercourse does carry a higher risk than most other forms of sexual activity. The lining of the rectum has fewer cells than that of the vagina, and therefore can be damaged more easily, causing bleeding during intercourse. This can then be a route into the bloodstream for infected sexual fluids or blood. There is also a risk to the insertive partner during anal intercourse, though this is lower than the risk to the receptive partner.

Does Menstruation Raise The Risk Of Hiv Transmission To Sexual Partners In Other Ways
If a person living with HIV is not taking antiretroviral treatment, levels of HIV in their vaginal fluid are likely to be higher during menstruation. Several studies have shown that viral load in the female genital tract can vary during the menstrual cycle, including a 2004 study which found that viral load levels in cervico-vaginal fluid tended to peak at the time of menstruation and fall to the lowest level just prior to ovulation, usually midway through the cycle. This would raise the risk of HIV transmission if preventative methods werent being used.
However, due to the effectiveness of HIV treatment, the bodily fluids of someone living with HIV are likely to have no detectable virus . Levels of HIV in blood and cervico-vaginal fluid are usually correlated, although viral load in vaginal secretions may fall more slowly than in blood so may not be undetectable for a few months after viral load has become undetectable in blood.
Measurement of the amount of virus in a blood sample, reported as number of HIV RNA copies per milliliter of blood plasma. Viral load is an important indicator of HIV progression and of how well treatment is working.
If unsure, condoms, dental dams and PrEP are all options that reduce the risk of HIV infection during sex with a person living with HIV who is menstruating.
