Breastfeeding is perfectly acceptable in mothers that are affected by gastroenteritis, as long as their clinical condition permits it (Lawrence 2016 p.776-791, Appendix D: Precautions and Breastfeeding Recommendations for Selected Maternal Infections). Medication used in the few diarrhea ailments that require specific pharmacological treatment are compatible with breastfeeding. The germs, viruses or bacteria that cause gastroentercolitis are not transmitted by milk. Standard preventive measures (hand washing, use of gloves, meticulous hygiene) and for contact (use of clothes to avoid direct contact with cutaneous areas that may be contaminated) are required to prevent the transmission from mother to child (Lawrence 2016 p.408 -409). Breast milk contains immunoglobulin A (IgA) and other defensive elements (Coppa 2016) against various infectious diseases, so there is a greater risk of transmission if the mother affected by gastroenteritis interrupts breastfeeding.Numerous studies have shown the benefits of breastfeeding in preventing morbidity and mortality from gastroenteritis and other infections in communities from poor and developing countries, as well as in industrialized countries (Paris 2006).
