Neonatal pneumonia can be mild or severe. Severe pneumonia is mainly characterized by cough, shortness of breath, significant tracheal tug signs, and some babies may have cyanosis around the lips, which indicates hypoxia. This type of pneumonia is serious and requires timely medical attention at a hospital. Common manifestations of mild pneumonia include slight shortness of breath, occasional white foam from the mouth, or some babies having phlegm sound in the throat. Chest X-rays show imaging changes in mild cases. Even with mild pneumonia, it is important to seek timely medical care and intervention to shorten the recovery time. Severe pneumonia, however, requires a longer recovery time.
