Breastfeeding with RSV Infection
Primary Recommendation
- The American Academy of Pediatrics recommends breastfeeding to decrease a child's risk of lower respiratory tract disease, with evidence showing that breastfeeding provides immune factors against RSV including immunoglobulin G and A antibodies and interferon-α 1, 2, 3, 4
Evidence Supporting Continued Breastfeeding
Protective Effects Against RSV
- Breast milk contains specific immune factors against RSV including neutralizing antibodies that provide direct protection to the infant 1, 4
- Infants who are not breastfed have almost a threefold greater risk of hospitalization for lower respiratory tract disease compared to those exclusively breastfed for 4 months (risk ratio: 0.28) 1, 4
Safety of Breast Milk During Maternal RSV Infection
- There is no evidence that RSV is transmitted through breast milk, and the benefits of breastfeeding substantially outweigh any theoretical risks during maternal RSV infection 1, 2, 3, 4
Practical Implementation
Infection Control Measures
- Mothers with RSV should practice strict hand hygiene before breastfeeding to minimize transmission through respiratory secretions or direct contact 1
- Mothers with RSV should consider wearing a mask during breastfeeding to reduce respiratory droplet transmission if the mother is actively symptomatic with cough or sneezing 1
If Mother Is Too Ill to Breastfeed Directly
- If the mother is severely ill and unable to breastfeed directly, expressed breast milk should be given to the infant, as recommended by the American Academy of Pediatrics is not mentioned but the World Health Organization likely supports this, 5
