As a rule, TB is not transmitted through breast milk. Tuberculosis is an infectious disease of the respiratory system that is transmitted mainly through droplet transmission. Therefore, if a mother with TB coughs or coughs up sputum while breastfeeding, there is a possibility that the TB bacillus may be passed to the baby through droplets, and the baby’s resistance is weak, which may then lead to the development of TB in the baby. However, tuberculosis is usually not transmitted through breast milk. It is recommended that if a mother with tuberculosis tries to stop breastfeeding because regular anti-tuberculosis treatment takes a long time and the side effects of anti-tuberculosis treatment are relatively high because of the combination of many kinds of drugs, which can also have some adverse effects on the baby.
