If your baby has a whistling nose during a fever, you should go to a pediatrician or otolaryngologist to see if there are any specific lesions in the nasal cavity, and specific treatment is needed for the type of lesion. In most cases, fever and nasal whine are caused by inflammation of the nasal cavity, and anti-inflammatory treatment is often more effective. First of all, observe the color of the nasal discharge. If the nasal discharge is clear, the effect is often better with cold medicines and antiviral drugs, and the child can be treated with aminophenol pseudo-lax dispersible tablets, pediatric aminophenol xanthamine pellets, and pudilan anti-inflammatory oral solution. If there is yellow and sticky nasal mucus, most of the time bacterial infections cause nose whistling and fever, the effect of antibiotic treatment is often better.
