How Long Can Hiv Survive Outside The Body
Once outside the body, HIV usually cant survive for very long. Coming into contact with blood or semen that has been outside the body doesnt generally pose a risk for HIV transmission.
Similarly, the risk of passing on HIV to someone else if you have a detectable viral load and cut yourself is also very low. Wash away any blood with soap and hot water and cover the wound with a sticking plaster or dressing.
Types Of Condomless Sex And Risk Of Hiv
During condomless sex, HIV in the bodily fluids of one person may be transmitted to the body of another person through the mucous membranes of the penis, vagina, and anus. In very rare cases, HIV could potentially be transmitted through a cut or sore in the mouth during oral sex.
Out of any type of condomless sex, HIV can most easily be transmitted during anal sex. This is because the lining of the anus is delicate and prone to damage, which may provide entry points for HIV. Receptive anal sex, often called bottoming, poses more risk for contracting HIV than insertive anal sex, or topping.
HIV can also be transmitted during vaginal sex without a condom, although the vaginal lining is not as susceptible to rips and tears as the anus.
The risk of getting HIV from oral sex without using a condom or dental dam is very low. It would be possible for HIV to be transmitted if the person giving oral sex has mouth sores or bleeding gums, or if the person receiving oral sex has recently contracted HIV.
In addition to HIV, anal, vaginal, or oral sex without a condom or dental dam can also lead to transmission of other STIs.
Letting Partners Know You Have Hiv
If you have just been diagnosed with HIV, it will likely be a difficult time. You might still be struggling to come to terms with diagnosis.
During this time, it is important to let any sexual or injecting partners know they may have been exposed to HIV as soon as you can, so they can be tested and offered PEP if appropriate.
You do not have to do this alone. Your doctor or the Department of Health and Human Services Partner Notification Officers can help you through this process and ensure your identity is not revealed.. Both groups can provide information, support, and guidance for people living with HIV.

Does Hiv Viral Load Affect Getting Or Transmitting Hiv
Yes. Viral load is the amount of HIV in the blood of someone who has HIV. Taking HIV medicine daily as prescribed can make the viral load very lowso low that a test cant detect it .
People with HIV who take HIV medicine daily as prescribed and get and keep an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
HIV medicine is a powerful tool for preventing sexual transmission of HIV. But it works only as long as the HIV-positive partner gets and keeps an undetectable viral load. Not everyone taking HIV medicine has an undetectable viral load. To stay undetectable, people with HIV must take HIV medicine every day as prescribed and visit their healthcare provider regularly to get a viral load test. Learn more.
What Is The Treatment For Hiv
Individuals who are HIV positive will likely need to see a specialist. As with many other conditions, early detection offers more options for treatment. Today, there are medical treatments that can slow down the rate at which HIV weakens the immune system. However, there are other treatments that can prevent or cure the conditions associated with HIV. Anti-retroviral drug therapy may be given to a pregnant woman, which has proven to greatly reduce the chance of an infant developing HIV. A cesarean section may be recommended to reduce infant transmission from the birth canal. In the U.S., where other feeding options are available, an infected mother should be discouraged from breastfeeding her infant. Consult your child’s doctor for more information regarding various drug therapies.

Reducing The Risk Of Hiv Transmission
The most effective way to prevent HIV transmission during sex is to use a condom. Get a condom ready before any sexual contact occurs, since HIV can be transmitted through pre-ejaculate, vaginal fluid, and from the anus.
Lubricants can also help reduce the risk of HIV transmission by helping to prevent anal or vaginal tears. The right lubricants also help prevent condoms from breaking. Only water-based lubricants should be used with condoms, because oil-based lube can weaken latex and sometimes cause condoms to break.
The use of a dental dam, a small plastic or latex sheet that prevents direct contact between the mouth and the vagina or anus during oral sex, is also effective at reducing the risk of HIV transmission.
For people who may have a higher risk for contracting HIV, preventive medication is an option. Pre-exposure prophylaxis medication is a daily antiretroviral treatment.
Everyone at increased risk of HIV should begin a PrEP regimen, according to a recent recommendation from the US Preventive Services Task Force. This includes anyone who is sexually active with more than one partner, or is in an ongoing relationship with someone whose HIV status is either positive or unknown.
Although PrEP does provide a high level of protection against HIV, its still best to use condoms as well. PrEP provides no protection against STIs other than HIV.
Viral Load & Medications
If someone has HIV, this does not mean that they are restricted to celibacy. Many people with HIV still continue to have safe, enjoyable sex lives without spreading the virus. Always using a condom or barrier method is an important first step to prevent the sharing of HIV containing fluids.
Antiretroviral therapy : Another way to help decrease the risk of spreading HIV is to lower a personâs viral loadâthe amount of HIV in a personâs blood. Viral loads can be lowered using medications called antiretroviral therapy . These medications can lower the HIV viral load so much that HIV may not even be detectable on a blood testâthis is called an undetectable viral load . When a person’s viral load in undetectable, they have effectively no risk of transmitting the HIV virus to a non-infected partner . Taking these medication will help keep a person with HIV healthy while also helping prevent the spread of HIV to another person. This is not a cure, however. If medication is taken incorrectly or stopped, HIV viral loads will increase again and transmission can occur. Condoms and other barrier methods should still always be used during sex .

How Long Does It Take For Hiv To Progress To Aids
How long does it take for HIV to progress to AIDS? In all but a few rare cases, if left untreated, HIV will progress to a stage of infection called AIDS. This is when the immune defenses have been compromised, and the body is less able to defend itself against potentially life-threatening infections.
I Am Hiv Positive How Can I Prevent Passing Hiv To Others
Take HIV medicines daily. Treatment with HIV medicines helps people with HIV live longer, healthier lives. ART can’t cure HIV, but it can reduce the amount of HIV in the body . One of the main goals of ART is to reduce a person’s viral load to an undetectable level. An undetectable viral load means that the level of HIV in the blood is too low to be detected by a viral load test. People with HIV who maintain an undetectable viral load have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
Here are some other steps you can take to prevent HIV transmission:
- Use condoms correctly every time you have sex.
- Talk to your partner about taking PrEP.
- If you inject drugs, don’t share your needles, syringes, or other drug equipment with your partner.

Why Do People With Recent Hiv Infection Account For A Disproportionate Number Of Transmissions
Higher infectiousness
The elevated viral load of someone recently infected with HIV is the main biological reason that they are more likely to transmit HIV to others at this time. The higher the viral load, the greater the risk is of transmitting HIV to others through unprotected sex. Researchers estimate that the risk of transmitting HIV to another person from one act of unprotected sex is 26 times higher during the first three months after infection than during the months and years that follow.“10”,11
More high-risk behaviour
A high viral load alone is not enough to transmit HIV to another person a recently infected individual also needs to be engaging in activities that can lead to the transmission of HIV, such as unprotected sex. Unfortunately, a person who has recently been infected with HIV is more likely to be engaging in high-risk behaviours than a person who has been infected for a longer period of time.12,13,14,15 There are two possible explanations for this. First, a recently infected individual is more likely to be engaging in high-risk behaviours because this is what led to their HIV infection. Second, many recently infected individuals are unaware of their HIV status and therefore may not realize the importance of having safer sex.
How Soon Do Sti Symptoms Show Up
If you’ve had sex with a new partner, you may become aware of every little ache down below or spot on your skin, and worry that it could be a symptom of an STI.
Many STIs won’t give you any symptoms at all, but if they do it’s good to know how soon after sex they develop. The period of time between getting infected and developing symptoms is known as the incubation period. Here you will find information about the incubation period of the most common types of STIs.

Who Should Get Tested For Hiv
Roughly one in seven Americans who have HIV dont know they do. The U.S. Centers for Disease Control recommends that everyone between the ages of 13 and 65 get tested at least once. If you are in a higher risk group, you should consider more frequent testing.
Even if you tested negative, you should get tested if you can answer yes to any of these questions about your activity since that test. Have you:
- Had sex with another man ?
- Had anal or vaginal sex with someone who is HIV-positive?
- Had more than one sex partner?
- Injected drugs with a shared needle?
- Received another STI diagnosis?
- Had sex with someone who could answer yes to any of these questions?
If you believe you may have had HIV exposure within the last 72 hours, talk to your healthcare provider. You may be able to get post-exposure prophylaxis — ie, medication. A PEP can prevent HIV when administered correctly. The sooner you begin to take it, the better, although it isnt 100% effective.
Reducing The Number Of Transmissions From Recently Infected Individuals: Challenges And Solutions
Because recently infected individuals account for a large number of HIV transmissions, identifying these individuals and helping them reduce their risk of passing HIV to others is critical to HIV prevention. Research shows that when people become aware of their HIV infection and are provided with access to prevention and care services, most take measures to reduce their risk of transmitting HIV to others.“12”
There are two major challenges to identifying recently infected individuals:
As a consequence, many people who have recently become infected are unaware of their infection, as are their partners. Those who are recently infected may therefore continue to engage in high-risk behaviours until they are diagnosed with HIV.
Your organization may be able to play a role in overcoming these challenges, identifying these individuals, and reducing their risk of transmitting HIV to others.
Challenge: Low levels of HIV testing
It is estimated that 26% of people who are HIV-positive in Canada do not know that they are infected16 and many do not learn of their HIV status until they have been infected for several years.17,18 The low levels of HIV testing in Canada means that most recently infected people probably pass through the brief stage of HIV infection when their viral load is elevated without getting tested for HIV.

Sex Toys Fingering Fisting And Hiv
Sex toys, such as dildos, come into direct contact with rectal/vaginal fluids and mucous membranes. This means sharing an uncleaned dildo or other toy can pass on HIV. Using sex toys on your own has no risk.
There is no direct risk of HIV from fingering or fisting , but be aware of being rough. Damage to anal/vaginal tissues, especially if there is any bleeding, will increase risk of HIV transmission if you then have anal, vaginal or oral sex later.
How Soon After Exposure To Hiv Can Tests Detect I Have The Virus
The window of time between exposure to HIV and when a test will show you have the virus varies from person to person and by the type of test:
- Nucleic acid test : The NAT test can detect HIV infection the earliest. It can tell if you have HIV infection 10 to 33 days after exposure.
- Antigen/antibody test: The antigen/antibody test can detect infection 18 to 45 days after exposure when performed by a lab using blood from a vein. If the sample is from a finger prick, the window is 18 to 90 days after exposure.
- Antibody test: Antibody tests can detect infection 23 to 90 days after exposure.
If your initial test is negative, get a second test after the window of time has passed. The second test can confirm your negative result in case you got tested before the infection was active in your body.
Remember, post-exposure prophylaxis can help prevent infection, but you must start it within 72 hours of possible infection. Talk to your healthcare provider about how to start PEP.

How Do You Get Hiv
HIV infection can occur in the following ways:
- Unprotected sexual intercourse, especially receptive anal intercourse
- Multiple sexual partners
- Sexually transmitted diseases: Chlamydia and gonorrhea infections increase the HIV transmission risk by three times syphilis raises the transmission risk by seven times and genital herpes raises the infection risk by 25 times during an outbreak
- Sharing IV needles or injections
- Receiving HIV infected blood products
- Needle-stick injuries
- Maternal HIV infection : The risk of transmission can be reduced at birth by practices like cesarean delivery and prenatal antiretroviral therapy in the mother, and antiretroviral therapy in the newborn immediately after birth
How Is Hiv Transmitted
The person-to-person spread of HIV is called HIV transmission. People can get or transmit HIV only through specific activities, such as through sex or injection drug use. HIV can be transmitted only in certain body fluids from a person who has HIV:
- Blood
- Vaginal fluids
- Breast milk
HIV transmission is only possible if these fluids come in contact with a mucous membrane or damaged tissue or are directly injected into the bloodstream . Mucous membranes are found inside the rectum, the vagina, the opening of the penis, and the mouth.
In the United States, HIV is spread mainly by:
- Having anal or vaginal sex with someone who has HIV without using a condom or taking medicines to prevent or treat HIV
- Sharing injection drug equipment , such as needles, with someone who has HIV
HIV can also spread from a woman with HIV to her child during pregnancy, childbirth , or breastfeeding. This is called mother-to-child transmission of HIV.
You can’t get HIV from casual contact with a person who has HIV, such as a handshake, a hug, or a closed-mouth kiss. And you can’t get HIV from contact with objects such as toilet seats, doorknobs, or dishes used by a person who has HIV.

What Happens If The Test Is Positive
If you receive a positive result, you will want to work with your healthcare provider on a treatment plan. Your healthcare provider will determine how far HIV has progressed and recommend medicines to help you manage it.
You will also want to talk about your diagnosis with your sexual partner. If you and your partner have had unprotected sex, you could have transmitted the virus to them. They should get tested, too.
What Types Of Tests Diagnose Hiv
To diagnose HIV, healthcare providers can order any of three tests:
- Nucleic acid test: The NAT test looks for the virus in your blood. It is a thorough laboratory test but can be costly. The results can take several days to receive.
- Antigen/antibody test: This test looks for antibodies and antigens to HIV in your blood. Your immune system forms antibodies when it comes in contact with viruses, such as HIV. Antigens, however, are foreign substances that activate your immune system. HIV has a particular antigen that this test can find. This rapid test uses a drop of blood from a finger prick and can give you results in roughly 30 minutes.
- HIV antibody test: This test is similar to the antigen/antibody test, but it only looks for the antibody. Just like the antigen/antibody test, this test produces results in around 30 minutes. It uses either a drop of blood from a finger prick or a swab of saliva.
Some states allow for home testing. There are two types of home tests:
- Rapid self-test: The only rapid self-test available in the United States uses a saliva sample to check for infection. After you receive your kit, you swab your gums and use the test kit to get results.
- Mail-in self-test: This test uses a blood sample from a simple finger prick. All of the supplies are in the kit to help you take the sample, package it and send it to the lab. A healthcare provider will tell you the results.
