Breastfeeding can be a supported choice when ART is taken consistently and viral load has stayed below 50 copies/mL for at least three months before delivery. Current U.S. guidance calls for shared decision-making and continued care during breastfeeding. With sustained suppression, breast-milk transmission risk is below 1%, but not zero. Properly prepared formula or pasteurized banked donor milk eliminates HIV transmission through breast milk.[2]
What changed, and when
On January 31, 2023, NIH's Office of AIDS Research announced that HHS HIV clinical practice guidelines now support shared decision-making on infant feeding, and quantified the risk of HIV transmission through breastfeeding for people who are virally suppressed as less than 1%. In the guidelines' own account of what preceded it: because of the potential for HIV transmission in human milk, previous U.S. clinical guidelines did not recommend breastfeeding for individuals with HIV[1].
The HHS Panel was explicit about why it changed. It balanced the low risk of transmission with strong community desire to breastfeed, acknowledged community concerns and the desire for bodily autonomy, and promoted a greater focus on shared decision-making. It also noted that restricting breastfeeding may increase inequities that already exist for many women with HIV — including health risks and access to safe water and formula — and that breastfeeding is congruent with many community norms and cultural traditions[1]. In other words, the change came partly from science and partly from listening.
Is this still current in 2026? Yes. The HHS Perinatal Guidelines section Preventing HIV Transmission During Infant Feeding carries "Updated: June 25, 2026 / Reviewed: June 25, 2026" and still centers shared decision-making[3], and the Perinatal Guidelines "What's New" page likewise carries 2026 dates[4].
What the current guidance actually says
Counseling comes first. When there is potential for perinatal transmission, the guidelines call for evidence-based, patient-centered counseling to support shared decision-making about infant feeding — beginning before conception or as early as possible in pregnancy, reviewed throughout pregnancy, and revisited after delivery[2].
The core numbers and thresholds:
- Zero-risk option: replacement feeding with properly prepared formula or pasteurized donor human milk from a milk bank eliminates the risk of postnatal HIV transmission through breastfeeding[2].
- Breastfeeding with suppression: achieving and maintaining viral suppression (under 50 copies/mL) through ART during pregnancy and postpartum decreases breastfeeding transmission risk to less than 1%, but not zero[2].
- When breastfeeding is supported: if ART is taken consistently and the viral load is maintained under 50 copies/mL for at least 3 months before delivery, counseling should cover formula, banked donor milk, and breastfeeding — and those who choose to breastfeed should be supported in that decision[2].
- When replacement feeding is recommended: when ART is not being taken or viral suppression has not been achieved during pregnancy (at minimum through the third trimester) and at delivery, formula or banked pasteurized donor human milk is recommended[2].
Choosing formula is equally supported, not a fallback: if formula feeding is chosen, providers should support that decision, ask about potential barriers, and explore ways to address them[2].
For parents who choose breastfeeding with sustained suppression, NIH recommends exclusive breastfeeding for the first six months, then complementary foods with continued breastfeeding if desired. There is no evidence that necessary formula supplementation increases infant HIV risk when ART and viral suppression are maintained. The care plan includes support for adherence, infant preventive medicines as appropriate and ongoing HIV testing.[2]
If viral load becomes detectable at 50 copies/mL or higher, temporarily stop or discontinue breastfeeding and use replacement feeding while the result is rechecked and the care team assesses next steps. Most experts recommend permanently stopping breastfeeding at 200 copies/mL or higher. If a repeat result is below 50, resuming is a shared decision. Planned weaning over two to four weeks may be safer, but a new detectable viral load requires prompt clinical assessment.[2]
Mastitis, bleeding nipples or infant thrush need prompt assessment. For a problem in one breast, NIH describes expressing and discarding or appropriately treating milk from the affected side while feeding or pumping from the unaffected side, with the clinical team’s guidance.[2]
Infant HIV testing continues during breastfeeding and afterward: NIH recommends virologic tests at four to six weeks and three months after breastfeeding ends. Testing must also account for when infant preventive ARVs stop; an additional test two to six weeks afterward may be needed. The pediatric team should set the complete schedule.[11][2][4]
The evidence behind "less than 1%, but not zero"
Start with the baseline this guidance replaced. Without maternal ART or infant preventive antiretrovirals, the risk of an infant acquiring HIV through breastfeeding is 15% to 20% over 2 years[3]. Everything below is what treatment does to that number.
- PROMISE (more than 2,400 women with CD4 counts of 350 cells/mm³ or higher), comparing extended infant nevirapine with maternal ART: estimated transmission of 0.3% at 6 months and 0.6% at 12 months, the same in both arms[3]. In the maternal-ART arm (1,220 mother–infant pairs) there were 7 transmissions; in 2 of those, maternal plasma HIV RNA was undetectable or under 40 copies/mL at the infant's first positive sample — and in both, maternal HIV RNA had been detectable at delivery[5].[12]
- 2017 systematic review and meta-analysis (6 studies, ART started in pregnancy and continued at least 6 months postpartum): pooled postnatal transmission at 6 months of 1.1% (95% CI 0.32%–1.85%), with individual study rates from 0.2% to 3.1%[3].
- 2025 systematic review and meta-analysis (13 studies): monthly postnatal transmission risk while breastfeeding of 0.1% (95% CI 0.0–0.2) with a recent maternal viral load under 50 copies/mL, versus 0.3% (95% CI 0.0–1.8) at 50 copies/mL or higher[3].
- Mma Bana (Botswana) provides another example of why the risk is not called zero: two lactational transmissions occurred despite maternal plasma and breast-milk RNA below 50 copies/mL at one and three months postpartum. In one case viral load was elevated at delivery; in the other, adherence concerns were reported. A suppressed measurement near detection of infant HIV does not establish uninterrupted suppression throughout exposure.[3]
- A BAN secondary analysis associated better maternal ART adherence with lower plasma and breast-milk viral loads; no infant acquisitions occurred while maternal plasma viral load remained below 100 copies/mL. A 2023 review also described small high-income-country case series with no reported transmissions when ART began before pregnancy or in the first trimester. Those limited observations do not establish zero risk.[3][5]
How this sits with U=U. For sex, the evidence is settled: people with HIV who take ART as prescribed and maintain a viral load below 200 copies/mL will not transmit HIV to their sex partners[2]. Breastfeeding is where the language stops at "very low" rather than "zero" — federal guidance uses a stricter threshold (sustained under 50 copies/mL), quantifies the residual risk as less than 1% but not zero, and documents the handful of transmissions that occurred despite suppression at the time of testing[3]. That gap is exactly why the guidelines chose shared decision-making instead of either a prohibition or a blanket reassurance[1].[13]
Where CDC and the AAP stand
CDC supports patient-centered counseling and shared decision-making about infant feeding before pregnancy or as early as possible, continuing after delivery. Properly prepared formula or pasteurized donor milk eliminates transmission through breast milk. Maintained viral suppression on ART reduces breastfeeding transmission to less than 1%, but does not eliminate it.[6]
The American Academy of Pediatrics takes the same shape. In its 2024 clinical report, AAP states that avoidance of breastfeeding is the only infant feeding option with 0% risk of HIV transmission — and that pediatricians should be prepared to offer a family-centered, nonjudgmental, harm-reduction approach to support people with HIV on ART with sustained viral suppression below 50 copies/mL who want to breastfeed. For people not on ART or without viral suppression, clinicians should recommend against breastfeeding[7].
AAP put it in plainer words for its own members: while many pediatricians were taught that breastfeeding is contraindicated for people with HIV, this is no longer the case, and people on ART maintaining a viral load under 50 copies/mL should be supported to choose the feeding option that best suits their needs — their own milk, formula, or certified banked donor milk. AAP names mastitis, cracked nipples, and infant thrush as complications that can theoretically increase transmission risk, and recommends a multidisciplinary team[8].
The choice should be discussed with a care team that understands HIV and infant feeding. Formula and pasteurized donor milk eliminate the breast-milk transmission route. Breastfeeding with sustained suppression is a supported option with a small residual risk and a plan for treatment, monitoring and feeding changes when needed.[6][7]
Your rights, and where to get help
One line in the guidelines deserves to be read out loud, because it is the answer to a fear many parents carry: engaging Child Protective Services or similar agencies is not an appropriate response to infant feeding choices impacted by HIV[2]. NIH states the same thing in its own words — it is inappropriate to engage CPS or similar services in response to the infant feeding choices of people with HIV[1]. If a provider raises that threat, they are out of step with federal guidance, and you can say so.
Your clinician can obtain free, round-the-clock specialist consultation through the National Perinatal HIV/AIDS Hotline at 844-275-6222. This is a clinical consultation service; bring the number to your HIV, obstetric or pediatric team if they need help planning your care.[2][8][14]
Start the feeding conversation before conception or early in pregnancy and revisit it as results and circumstances change. You should receive respectful, nonjudgmental care whichever option you choose; the medical recommendation depends on treatment, sustained suppression and your individual circumstances.[2]
Florida: pregnancy care and support
Florida’s TOPWA program helps underserved pregnant people with HIV or at risk of HIV and substance use connect to medical and social services. DOH lists funded programs in Broward, Duval, Hillsborough, Miami-Dade, Orange, Palm Beach, Pinellas and St. Lucie counties. Services include help accessing prenatal care, HIV testing, family planning, ADAP or Medicaid and prevention education. The state also lists Ryan White Part D providers and Baby RxPress. Ask about current eligibility and local availability.[9]
Florida’s 2023 surveillance report recorded 409 infants born that year with perinatal HIV exposure; one was diagnosed with HIV and none with AIDS at the report’s data cutoff. This birth-cohort measure should not be compared directly with the eight perinatally acquired HIV diagnoses reported in the calendar year 2022, which is a different measure. A Part D clinic or TOPWA worker can help eligible families connect to care.[10]
Related questions
Can I breastfeed if I have HIV in the United States?
It can be a supported choice when ART is taken consistently and viral load has stayed below 50 copies/mL for at least three months before delivery. NIH’s June 2026 guidance supports discussing breastfeeding, formula and banked donor milk, with a plan for continued treatment, monitoring and infant care.[2]
What is the actual risk of passing HIV through breast milk?
NIH describes the risk during breastfeeding with sustained viral suppression on ART as less than 1%, but not zero. Studies differ in when treatment began, adherence, infant prophylaxis and length of follow-up, so their monthly and cumulative percentages are not interchangeable estimates of your individual risk.[2][3]
Is formula still recommended?
Properly prepared formula and pasteurized banked donor milk eliminate HIV transmission through breast milk. Breastfeeding with sustained suppression is a supported alternative with a small residual risk. If you choose formula, your team should support that decision and help address access barriers.[2][6][7]
Can someone call child protective services over my feeding choice?
Federal clinical guidance says that involving Child Protective Services solely in response to infant-feeding choices impacted by HIV is inappropriate. That is a clinical recommendation, not a guarantee about every legal situation. Your care team can request specialist advice from the National Perinatal HIV/AIDS Hotline at 844-275-6222.[1][2][14]
