How long does it generally take to treat pediatric bronchopneumonia with intravenous fluids and atomization?

Patient's question:

Cough with phlegm, low-grade fever, have been sick for several months, caused by a cold

Doctor's answer:

Hello, your baby's condition should be checked for mycoplasma. If there is mycoplasma infection, using your current medication is ineffective. You should switch to azithromycin, which is more effective. It usually takes about ten days to recover.
