Novel coronavirus is mainly spread through respiratory droplet transmission and contact transmission. If a confirmed patient breastfeeds her baby, she will infect her baby with the new coronavirus. If the mother is healthy and does not have suspected symptoms such as cough or fever, breastfeeding the baby will not cause the new coronavirus infection. If the mother is a close contact and has suspected symptoms, breastfeeding the baby during home isolation may cause the baby to become infected. In this case, the mother should not only follow the home isolation norms, but also wear a medical mask when she is near her baby and wash her hands carefully before close contact with her baby, so as to reduce the risk of her baby getting infected.
