The time it takes for an infant to fully recover from pneumonia without coughing depends on the severity of the disease and the individual’s physical condition, ranging from 1 to 2 weeks for short periods of time to 1 to 2 months for long periods of time. If the infant is a full-term baby, the physical condition is good. And simple, caused by viral, bacterial infection of bronchopneumonia, in giving symptomatic anti-inflammatory, anti-viral drugs, as well as nebulized inhalation after coughing symptoms may be rapidly reduced and improve, basically in about 1 ~ 2 weeks can be cured without coughing. However, if the baby is born prematurely, and there are congenital heart disease, pulmonary dysplasia and other underlying diseases, and there are allergies and other factors that make the cough symptoms more serious, and the duration of the disease is longer. This kind of prolonged cough needs to be treated according to the cause of the disease, and cannot be treated simply by anti-inflammatory and anti-viral treatment, cough and phlegm relief. In some cases, the duration of the disease can last for about 1~2 months. Therefore, the recovery time for pneumonia in infants and young children usually varies according to individual differences and the severity of the disease, and cannot be generalized.
