We need to double-check this result by taking another blood sample from you. It is very unlikely that this result will be any different.
Here you will find information about:
There is a lot of information available so you may want to read it one section at a time over the next few days.
Your HIV-positive result means that at some time you have been infected with the HIV virus (there is information included later about how you can catch HIV).
HIV is a virus that attacks the immune system (the body’s defence system). Over time, usually many years, the immune system becomes weaker, meaning that the body becomes less able to protect itself against serious illnesses.
There is very effective treatment available which means you can expect to live as long as anyone else.
Knowing you have the infection means that you can be monitored (that is, have special health checks and blood tests), supported by a specialist team and receive treatment when you need it. This can improve your health.
HIV can be passed from mother to child. This means that without any treatment (or special steps being taken), there is a chance that you could pass the virus to your baby. This could happen during pregnancy, when you give birth or when you breastfeed.
The benefit of knowing you are HIV-positive is that, by taking the steps listed later in this information there is a very good chance you can prevent passing the virus to your baby. This will reduce the chance of HIV being passed to your baby to less than one in 100. Without taking these steps, the chance of passing the virus to your baby is much higher.
HIV can be passed on in the following ways.
HIV is not passed to other people through everyday social contact, for example, going shopping, being with friends and family, eating meals together or kissing.
We will offer you an appointment at a specialist clinic for a full health check-up and assessment (or review) of the stage of your HIV infection. The HIV specialist will be able to answer your questions about HIV and give you support. They will continue to see you regularly, during pregnancy and after your baby is born.
Your midwife will also help you to plan your care and discuss your choices with you.
A number of blood tests are used to check the HIV infection. Two in particular help to decide when treatment is necessary. These are:
These tests will be arranged, as well as any others that are needed, and the results explained to you.
You will be recommended treatment at some time during your pregnancy and when you give birth. This is to:
Anti-HIV drug therapy (or treatment) is sometimes known as ART – Antiretroviral Therapy. The drugs do not kill the virus and will not cure HIV. However, they can prevent the growth of the virus so they reduce the amount in your bloodstream (the viral load). A blood test measures the viral load. People with undetectable viral loads stay healthier longer. They are also less likely to pass HIV infection to others.
When you are offered treatment with ART during your pregnancy, it will be discussed with you. The drugs will be tailored to your needs. After starting treatment, you will be monitored closely using blood tests and you will have regular appointments to make sure that the drugs are suitable for you. If you have any side effects, they can be dealt with. It usually depends which side effects you have, but they can often be treated with a short course of medication or by changing the times you take your ART.
If you have any worries, it is important that you discuss them with the HIV specialist team as they may be able to help. Remember that there is always help and support for you.
Stopping ART after your baby is born is not recommended. After your baby is born you will still need to be monitored and supported by the HIV specialist team.
If you did not know that you have HIV, you will not have been able to take steps to try to stop the virus passing to your baby. Without steps being taken, about one in four to six babies born to HIV-positive women will be infected.
If you take the steps listed below, the chance of your baby becoming infected with HIV is less than one in 100.
There are four important steps that we will discuss with you.
You will be recommended treatment at some time during your pregnancy and when you give birth.
If your HIV is well controlled near the date your baby is due, it may be possible to plan for a normal vaginal delivery. If you have any medical problems, a planned Caesarean section may be suggested. Your midwife and obstetrician will discuss this with you.
HIV can be passed to your baby in breast milk. Breastfeeding is not recommended to women who are
HIV-positive in the UK because there are safe alternatives available. It is advised that you give your baby formula milk. You can discuss this with your specialist team and your midwife.
It is recommended that free formula milk is available to women who are HIV-positive in Wales. You should give your baby formula milk until they are about 12 months old.
Anti-HIV medicine will be prescribed for your baby up to the first four weeks after birth. This medicine will give your baby extra protection against HIV infection. Your baby may also be prescribed antibiotics.
As part of your care during pregnancy you will normally be offered an appointment at a paediatric (children’s) clinic that has special skills in managing HIV. The specialist nurse or doctor will discuss tests and treatment for your baby with you.
If your baby has tested negative to the blood tests done soon after birth, and at six weeks of age and 12 weeks of age, and you are not breastfeeding, your baby should be free of HIV. But the doctors cannot say for certain that babies are not infected until they are 18 months old. This is because your baby may carry your antibodies to HIV until they are this age. An HIV test cannot tell the difference between your antibodies (passed to your baby before birth) and antibodies produced by your child because they have HIV infection.
For you and your baby to have the best care, it is necessary for you to receive care from a number of specialists – for example, the HIV clinic team, obstetrician (hospital doctor) and paediatrician (baby and child doctor). Your midwife will ask you if they can share information about you with the specialists directly involved in caring for you and your baby. We will not share information with others without your permission.
We will ask you whether you want us to tell your general practitioner (GP) that you have HIV. If you prefer that your GP does not know, we will respect your wishes. However, your GP will be aware of other health issues you may have and medicines you take. If they know that you have HIV, this can avoid interactions between HIV medication and other drugs they may prescribe.
If you are in a relationship, you may want to ask your HIV specialist about how to explain your positive test results to your partner. If your partner does not know whether they are infected, you should use condoms for sex to prevent you from passing the virus to your partner. Your partner should consider getting tested for HIV.
