HIV

  • What is HIV?

    HIV stands for Human Immunodeficiency Virus. Once someone is infected with HIV the virus will remain in their body for the rest of their life. There is currently no cure for HIV and no vaccine to prevent people from becoming infected. However, drug treatments can help most people with HIV to live much longer and feel well.

    HIV can be transmitted in a number of ways.

  • What causes HIV?

    HIV is a virus. When someone becomes infected with HIV the virus weakens and damages their body’s defence system (the immune system) so that it cannot fight off infections.
    Someone who has HIV is diagnosed as having AIDS only when tests show their immune system cannot cope and they develop one or more particular illnesses. The term AIDS is not used very often now. Late stage or advanced HIV is used instead.

  • How is HIV passed on?

    HIV can be passed from one person o another through sexual contact, and in a number of other ways. Both men and women can have HIV, and can pass it on. You don’t need to have lots of sexual partner to get HIV or pass it on.

    HIV can be passed on through heterosexual (straight) or homosexual (gay, lesbian) sex. In women who only ever have sex with women the risk of HIV being passed on is very low. Circumcised and uncircumcised men can get HIV and pass it on. Circumcision is when the foreskin is removed from the penis. Research is looking into whether circumcised men may have less risk of becoming infected with HIV.

    Most people with HIV will look and feel healthy, so you cannot tell who has the virus and you can pass on HIV without knowing you have it. HIV can be passed on even if someone is taking anti-HIV drugs.
    HIV is passed from one person to another when the blood, semen, pre-ejaculated (precum), vaginal fluids or breast milk of an infected person enters the body of an uninfected person by:

        Having unprotected vaginal, anal or oral sex
        Sharing sex toys
        Using a needle or syringe (works) which has already been used by someone who is infected with HIV.
        A woman with HIV can pass the virus to her baby before or during birth, or by breastfeeding.
        The risk of catching HIV from unprotected oral sex is low but it can happen. You are more at risk if:
        You throat or mouth is inflamed or you have cuts, sores, abrasions or any unhealed piercing in your mouth
        You partner ejaculates in your mouth
        You have just brushed or flossed your teeth
        You are giving oral sex to a woman who is having her period

    Having another sexually transmitted infection increases the risk of getting HIV or passing HIV on if you already have it.
    Although tests can detect HIV in urine and saliva, the level of virus in these fluids is thought to be too low to be infectious.
    You cannot get HIV from hugging, kissing, sneezes, coughs, sharing baths or towels, from swimming pools, toilet seats or from sharing cups, plates or cutlery. You cannot get HIV from any animals or insects, including mosquitoes.

  • Can HIV be passed on when receiving healthcare in the UK?

    It is now extremely rare to become infected with HIV when receiving healthcare in the UK. In the UK all health professionals – such as dentists, doctors, midwives and nurses, are required to follow infection control procedures when caring for any patient.

    Organ donors and blood from blood donors are also tested in the UK to reduce the risk of HIV being transmitted through infected blood, blood products or donated organs.
    Some countries do not have the same standards of medical and dental care as the UK, so there may be a risk of getting HIV from infected blood products or unsterile medical equipment if you receive healthcare in another country.

  • What are the signs and symptoms of HIV?

    Many people infected with HIV have no signs and symptoms at all. About half of people who become infected with HIV experience flu-like symptoms within a few weeks after injection. These may include fever, a rash, swollen glands, a sore throat, mouth or throat ulcers and aching muscles or joints. These symptoms are sometimes called sero-conversion illness and usually last for about 1-4 weeks.

    Some people are first diagnosed with HIV when they become ill due to their immune system becoming weakened.

  • How will I know if I have HIV?

    You can only be certain you have HIV if you have a test. If you or a partner think you might have HIV it is important that you don’t delay seeking advice and getting a test. Even if you don’t have symptoms you may wish to be tested, particularly if:

        You have recently had unprotected sex with a new partner
        A sexual partner tells you they have HIV
        You have shared drug injecting equipment
        You, or our partner, have had unprotected sex with other partners
        You, or your partner, have another sexually transmitted infection
        You are pregnant or planning a pregnancy

  • How soon after sex can I have a test?

    It is important not to delay getting a test if you think you might have HIV. You can have a test even if you do not have any signs or symptoms. You will usually be offered a HIV test when you go to the clinic.

    It can take up to three months after coming into contact with HIV before it is detectable in the blood – this is known as the window period. HIV can still be passed on during the window period even though it can’t be detected. As HIV may not show up on the test straightaway you may be asked to go back for a test three months after you had the sex that put you at risk of HIV.

  • What is a HIV test?

    A HIV test checks your blood for antibodies to HIV. When HIV enters your body, your immune system tries to fight off the infection by producing antibodies to the virus. It can take between three weeks and three months after you have been infected with HIV for there to be enough antibodies in your blood to show up on a HIV test.

    Newer types of HIV tests look for part of the HIV  virus known as the p24 antigen as well as looking for HIV antibodies. P24 antigen is a protein that is part of HIV which is produced in large quantities when you are first infected with HIV. This can be detected in the blood sooner than HIV antibodies. Tests that look for both antibodies and p24 antigen are known as combined antibody/antigen tests.
    HIV antibody testing can also be done by taking a sample of saliva but this test is not routinely recommended in the UK.

    Cervical screening test, routine blood test and swabs do not detect HIV. If you are not sure whether you have been tested for HIV, just ask.

  • What do they test results mean?

    If the result is HIV negative this means that no HIV antibodies or p24 antigen were found in your blood. If the test has been done at least three months after the time of your possible risk of infection, then you do not have HIV. If it was less than three months since the last time you could have been exposed to HIV, the test will be repeated at a later appointment.

    If the result is HIV positive this means that the test have detected HIV antibodies or P24 antigen in your blood. The test will be repeated to confirm the positive result. If both tests are positive this means you have HIV.

  • What does the test involve?

    The HIV test involves taking a sample of blood (either from your arm or from a finger prick) and looking for HIV antibodies, or antibodies and p24 antigen.

    A HIV test should only be done with your permission. You should understand what is involved in the test and how it might affect you. Before any testing takes place a doctor, nurse or health adviser should discuss with you:

        Why you think you might be at risk of HIV
        The benefits of testing
        How the result (negative or positive) might affect you and aspects of your life
        How and when the HIV test can be done
        Where the information about the test result will be recorded
        How the result will be given to you

    They may also give you a leaflet to explain some of the things you have discussed. Don’t be frightened to ask questions about anything you are not sure about.
    Before you decide to have a test you may wish to talk to someone about the implications that this could have on all aspects of your life and about who might have access to the HIV test result. The doctor, nurse, health adviser or a HIV organisation can help you with this. Some people feel sure that they would like to know whether they have HIV or not, but may not want to discuss it at first. You should choose the approach that suits you best.

  • How soon will I know the result of the test?

    This will vary depending on where you had the test done. The doctor, nurse or health adviser will talk to you about when the result will be available.

    At most services the result should be available within ten days. Some clinics offer same day testing. Not all clinics provide this services and an appointment is usually required.

    There are also a small number of clinics that offer rapid testing. This is when you have a HIV antibody test and are given the result in a short space of time (usually one hour). If the result is positive another test will be done to check that the result is correct.

  • How accurate are the tests?

    No test are 100 per accurate, but HIV tests should pick up almost all HIV infections if they are done at the right time. All positive HIV tests are repeated to confirm the result.

  • What happens if HIV isn’t treated?

    Once you are infected with HIV you will remain infected with the virus for the rest of your life, and will be able to pass it to someone else. There is currently no way of curing the virus or removing it from the body.

    Every individual will react differently to HIV. If the HIV isn’t monitored carefully and treatment given when necessary, it will cause long-term damage, and this will develop into late stage HIV infection (which can cause death).

  • Will I know now long I’ve had HIV?

    The HIV antibody test cannot tell you how long you have had the virus. If you have had more than one sexual partner it can be difficult to know which partner you got HIV from. If you feel upset or angry about having HIV and find it difficult to talk to your partner, family or friends, don’t be afraid to discuss how you feel with the staff at the clinic or general practice, or at a support organisation.

  • Should I tell my partner?

    If the test shows that you have HIV then it is very important that your current sexual partner(s) and any other recent partners are also tested. The staff at the clinic or general practice can help you with this, and discuss with you which of your sexual partners may need to be tested.

    You may be given a ‘contact slip’ to send or give to your partner(s) or, with your permission, the clinic can do this for you. The slip explains that they may have been exposed to a sexually transmitted infection and suggests that they go for a check-up. It may or may not say what the infection is. It will not have your name on it, so you confidentiality is protected. This is called partner notification. You are strongly advised to tell your partner(s).

  • Does anyone else need to know that I have had an HIV test?

    Information about your HIV test (whatever the result) should only be passed to someone else with your permission. You may be worried that other people may find out that you have HIV when you don’t want them to. Talk to your doctor or nurse if are concerned about the confidentialilty of your results.

    There are some circumstances when you might be asked if you have ever had a test, for example when applying for certain jobs, insurance or a mortage. Nowadays it is more common only to be asked if you have had a positive HIV test or are having treatment for HIV. It is important to understand how the answers to these questions might affect you.

  • Does HIV affect fertility?

    Many women with HIV are able to become pregnant, and men with HIV can father children. HIV positive men and women who are planning a pregnancy can get information and advice from an HIV organisation or their doctor or specialist on how to minimise the risk of infecting an HIV negative partner or the baby.

  • What happens if I am pregnant and I have HIV?

    If you have HIV and you are pregnant it is possible for HIV to pass to the baby while you are pregnant, during birth and when you breastfed. During your antenatal care you will be recommended to have an HIV antibody test. If you are HIV positive then you can discuss with the doctor or midwife:

        The benefits of antiretroviral therapy (drug treatment) to you and your baby
        Whether a caesarean birth is recommended
        If breastfeeding should be avoided

  • How can I help protect myself from sexually transmitted infections, including HIV?

    The following measures will help protect you from sexually transmitted infections and will also help prevent you from passing them on.

        Use condoms (male or female) every time you have vaginal or anal sex. If you can, avoid using condoms or spermicides containing Nonoxinol 9. This does not protect against HIV and may even increase the risk of infection. Evidence shows that standard strength condoms offer just as good protection as extra strong condoms. Water-based lubricant should be used with condoms for anal sex.
        If you have oral sex, cover the penis with a condom or the female genitals and male or female anus with latex or polyurethane (soft plastic) square. If you do not want to do this, try to avoid:
        Ejaculation into the mouth
        Giving oral sex to a women during her period
        Oral sex if your throat or mouth is inflamed or you have cuts, sores or abrasions in your mouth or on your gums
        Brushing or flossing your teeth before or after oral sex. These may increase your chances of passing on or getting HIV.
        If you are a woman and rub your vulva against your female partner’s vulva one of you should cover the genitals with latex or polyurethane (soft plastic) square.
        Avoid sharing sex toys. If you do share them, wash them or cover them with a new condom before anyone else uses them.
