Question
A three-month-old baby is showing symptoms of coughing but has no fever. The parents inquire if it could be pneumonia and what the possible causes might be.
Answer
Considering the baby may have an upper respiratory infection, which is an acute inflammation of the nasal cavity, throat, or larynx, usually caused by a virus and occasionally by bacteria. It is recommended to get plenty of rest and, if accompanied by headache and fever, appropriate antipyretic and analgesic medications can be taken. It is suggested to visit a hospital for a routine blood test to understand the white blood cell count and determine the extent of the infection. In daily life, it is important to drink plenty of water and encourage the baby to engage in physical activities to enhance their constitution and boost immunity.
