HIV living with treatment in infants
Informed by recognized medical guidance
Overview
HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. In infants, it is usually passed from mother to baby during pregnancy, birth, or breastfeeding. With proper treatment, infants with HIV can grow up healthy and strong. Treatment involves taking medicines every day to keep the virus under control and protect the immune system.
Key facts
- Babies can get HIV from their mothers during pregnancy, childbirth, or breastfeeding.
- Early testing and treatment are crucial for healthy development.
- With daily antiretroviral therapy (ART), most infants can live long, healthy lives.
- HIV treatment reduces the virus to undetectable levels, preventing transmission to others.
- Children on effective treatment usually have normal growth and development.
HIV in infants is now rare in countries with good prenatal care and prevention programs, but it still occurs in many parts of the world. With proper prevention, the chance of mother-to-child transmission can be less than 2%.
Infants born to mothers living with HIV. It can affect any baby if the mother's HIV is not well managed before or during pregnancy.
Symptoms
- Difficulty breathing or rapid breathing.
- Seizures or convulsions.
- Unconsciousness or very sleepy and hard to wake.
- Signs of severe dehydration (dry mouth, no tears, sunken eyes, minimal urine).
- High fever (above 38°C / 100.4°F) in an infant under 3 months.
- ⚠Persistent high fever not responding to usual care.
- ⚠Severe diarrhea or vomiting leading to dehydration signs.
- ⚠Any new rash with fever (may be sign of serious infection).
- ⚠Weight loss or failure to gain weight over several weeks.
- ⚠Breathing faster than normal or wheezing.
Common symptoms
- Some infected infants may have no symptoms for months or years.
- Poor weight gain or failure to thrive.
- Frequent infections (ear infections, pneumonia, thrush).
- Swollen lymph nodes (glands) in the neck, armpits, or groin.
- Diarrhea that does not go away.
- Fever lasting more than a few days.
Symptoms in children
- Delayed growth or development (slower to sit, crawl, walk).
- Recurring skin rashes or infections.
- Enlarged liver or spleen.
- Chronic cough or breathing problems.
Causes
Main causes
- HIV is caused by the human immunodeficiency virus. In infants, it is almost always transmitted from an HIV-positive mother during pregnancy, labor and delivery, or through breastfeeding.
Risk factors
- Mother living with HIV who is not on effective treatment during pregnancy.
- Mother's HIV viral load is high near delivery.
- Mother develops a new HIV infection during pregnancy or breastfeeding.
- Prolonged labor or premature rupture of membranes.
- Breastfeeding when the mother has an uncontrolled HIV infection.
When to see a doctor
See a doctor urgently if:
- If your baby shows any emergency symptoms listed above.
- If your baby has a fever and you know or suspect HIV exposure.
- If your baby has trouble feeding or shows signs of dehydration.
Book a routine appointment if:
- All pregnant women should be tested for HIV early in pregnancy. If positive, the baby should be tested within the first few weeks of life.
- If your baby was exposed to HIV, follow the doctor's schedule for testing and check-ups.
- Bring your baby for all routine well-child visits, even if they seem healthy.
Diagnosis
HIV in infants is diagnosed using a special blood test that looks for the virus itself (called a virologic test). This is different from standard antibody tests used in older children and adults. It can be done from birth to 18 months.
Tests that may be done
- HIV DNA or RNA polymerase chain reaction (PCR) test: This detects the virus in the baby's blood.
- Repeat testing is usually done at a few weeks and again at 4–6 months to confirm results.
- If the baby is older than 18 months, an antibody test may be used.
What to expect at your appointment
Testing is simple: a small blood sample is taken. Results usually come back within a few days to two weeks. Your doctor will explain the results and what they mean. A positive result means the baby has HIV. A negative result means the baby does not have HIV (if testing is done correctly and at the right times).
Treatment
The main treatment for HIV is antiretroviral therapy (ART). This is a combination of medicines that stop the virus from multiplying. For infants, ART is given as a liquid or syrup, usually once or twice a day. Treatment is lifelong. With consistent treatment, the virus can become undetectable in the blood, which means it stays under control and the baby stays healthy.
Self-care at home
- Give the medicine exactly as prescribed, at the same times each day.
- Keep a diary or set alarms to help remember doses.
- Store medicines correctly (some need refrigeration).
- Do not stop or change the dose without talking to the doctor.
- If you miss a dose, give it as soon as you remember, but do not double the dose. Ask your pharmacist or doctor for advice.
Medical treatments
Infants with HIV are treated with a combination of at least three antiretroviral drugs. These are specially formulated for babies (often as a liquid). The specific drugs are chosen based on the baby's weight, age, and the mother's treatment history. Treatment is started as soon as possible after diagnosis, often within the first few weeks of life. Regular blood tests monitor the virus level (viral load) and the baby's immune cells (CD4 count) to make sure treatment is working.
When is surgery considered?
Surgery is not used to treat HIV itself. However, HIV-positive infants may need surgery for other conditions. Before surgery, the medical team will take extra precautions to protect the baby's immune system. Always tell the surgeon that the baby has HIV.
Living with this condition
Living with HIV means taking daily medication, keeping regular doctor visits, and monitoring blood tests. With treatment, the baby can have a normal childhood – go to daycare, play with friends, and get all routine vaccinations. The only extra care is giving the medicine and watching for any signs of infection.
Lifestyle tips
- Keep all medical appointments and blood test schedules.
- Follow the immunization schedule – most vaccines are safe and important for HIV-positive children.
- Practice good hygiene to reduce infection risk (handwashing, clean bottles and pacifiers).
- Avoid exposing the baby to people with active infections like chickenpox or flu when possible.
Diet and exercise
Breastfeeding is generally not recommended for mothers with HIV unless they are on effective treatment and have an undetectable viral load (follow local guidelines). For bottle-feeding, use formula. As the baby grows, offer a healthy, balanced diet with plenty of fruits, vegetables, and proteins. Exercise is normal for the child's age – crawling, walking, and playing are all encouraged.
Mental health and emotional wellbeing
Having a baby with HIV can be stressful for parents. It is normal to feel worried, sad, or overwhelmed. Talk to your doctor or a counselor if you need support. As the child grows, they may face stigma or questions about their condition. Teaching them that HIV is just a part of their life – not their whole identity – can help. Family-based counseling can be very helpful.
Prevention
Yes, mother-to-child transmission of HIV can be prevented in most cases. All pregnant women should be tested for HIV. If a mother is HIV-positive, she can take antiretroviral medicines during pregnancy, labor, and after birth, which greatly reduces the risk to the baby. The baby may also receive preventive ART for a few weeks after birth. Avoiding breastfeeding (or using ART with undetectable viral load) further lowers the risk.
Vaccines
Routine childhood vaccines are safe for infants with HIV. However, some live vaccines (like the rotavirus vaccine or BCG for tuberculosis) may need special consideration. Talk to your child's doctor about the best vaccine schedule.
Screening programmes
All pregnant women should be screened for HIV early in pregnancy. If a woman is at high risk (e.g., living in a region with high HIV rates or having a partner with HIV), repeat screening in the third trimester may be recommended. Newborns of HIV-positive mothers should have virologic testing within the first few weeks of life.
Complications
If left untreated
- Severe immune system damage leading to frequent, serious infections.
- Failure to thrive (poor weight gain and growth).
- Developmental delays (slower to learn, talk, or move).
- Organ damage (liver, heart, brain).
- Increased risk of some cancers.
- Progression to AIDS (the most advanced stage of HIV) within a few years.
Long-term outlook
With early diagnosis and consistent antiretroviral treatment, the outlook for infants with HIV is excellent. Most children can achieve undetectable viral loads, have normal growth and development, and live into adulthood with a good quality of life. HIV is now a manageable chronic condition, not a death sentence. The key is to start treatment early and stick with it.
