Child has a cold, fever and cough. What cold medicine works fastest?

Patient's question:

No

Doctor's answer:

The following can be used for chest X-ray to determine the lesions of the bronchi and lungs. If there are no special conditions, please use anti-infection treatment (e.g., cefdinir, take it for three consecutive days to see if it is effective. If it is not effective, there may be an infection of other special bacteria. Sputum culture and drug sensitivity test can be performed to determine the effective antibiotic). Symptomatic treatment (if there is cough, take cough medicine such as dextromethorphan; if there is phlegm, use expectorant such as ambroxol).
