HIV/AIDS - pregnancy and infants
Human immunodeficiency virus (HIV) is the virus that causes AIDS. When a person becomes infected with HIV, the virus attacks and weakens the immune system. As the immune system weakens, the person is at risk of getting life-threatening infections and cancers. When that happens, the illness is called AIDS.
HIV can be transmitted to the fetus or the newborn during pregnancy, during labor or delivery, or by breastfeeding.
This article is about HIV/AIDS in pregnant women and infants.

Most children with HIV get the virus when it passes from an HIV-positive mother to the child. This can occur during pregnancy, childbirth, or when breastfeeding.
Only blood, semen, vaginal fluids, and breast milk have been shown to transmit infection to others.
The virus is NOT spread to infants by:
Most infants born to HIV-positive women in the United States do NOT become HIV-positive if the mother and infant have good prenatal and postpartum care.
Infants who are infected with HIV often have no symptoms for the first 2 to 3 months. Once symptoms develop, they can vary. Early symptoms may include:
Early treatment often prevents the HIV infection from progressing.
Without treatment, a child's immune system weakens over time, and infections that are uncommon in healthy children develop. These are severe infections in the body. They can be caused by bacteria, viruses, fungi, or protozoa. At this point, the illness has become full-blown AIDS.
Exams and Tests
Here are the tests a pregnant mother and her baby may have to diagnose HIV:
TESTS TO DIAGNOSE HIV IN PREGNANT WOMEN
All pregnant women should have a screening test for HIV along with other prenatal tests. Women at high risk should be screened a second time during the third trimester.
Mothers who have not been tested can receive a rapid HIV test during labor.
Woman known to be HIV positive during pregnancy will have regular blood tests, including:
TESTS TO DIAGNOSE HIV IN BABIES AND INFANTS
Infants born to women infected with HIV should be tested for HIV infection. This test looks for how much of the HIV virus is in the body. In infants born to HIV positive mothers, HIV testing is done:
If the result of 2 tests is negative, the infant does NOT have an HIV infection. If the results of any test is positive, the baby has HIV.
HIV/AIDS is treated with antiretroviral therapy (ART). These medicines stop the virus from multiplying.
TREATING PREGNANT WOMEN
Treating pregnant women with HIV prevents children from becoming infected.
TREATING BABIES AND INFANTS
Infants born to infected mothers start receiving ART within 6 to 12 hours after birth. One or more antiretroviral drugs should be continued for at least 6 weeks after birth.
HIV-positive women should not breastfeed. This holds true even for women who are taking HIV medicines. Doing so may pass HIV to the baby through breast milk.
The challenges of being a caretaker of a child with HIV/AIDS can often be helped by joining a support group. In these groups, members share common experiences and problems.
The risk of a mother transmitting HIV during pregnancy or during labor is low for mothers identified and treated early in pregnancy. When treated, the chance of her baby being infected is less than 1%. Because of early testing and treatment, there are fewer than 200 babies born with HIV in the United States per year.
If a woman's HIV status is not found until the time of labor, proper treatment can reduce the rate of infection in infants to about 10%.
Children with HIV/AIDS will need to take ART for the rest of their life. The treatment does not cure the infection. The medicines only work as long as they are taken every day. With proper treatment, children with HIV/AIDS can live a nearly normal lifespan.
When to Contact a Medical Professional
Call your health care provider if you have HIV or are at risk for HIV, AND you become pregnant or are thinking of becoming pregnant.
HIV-positive women who might become pregnant should talk to their provider about the risk to their unborn child. They should also discuss methods to prevent their baby from becoming infected, such as taking ARV during pregnancy. The earlier the woman starts medicines, the lower the chance of infection in the child.
Women with HIV should not breastfeed their baby. This will help prevent passing HIV to the infant through breast milk.
