Positive mycoplasma in children indicates the presence of a mycoplasma infection, which usually requires 3 to 14 days of intermittent azithromycin, but the duration of administration may vary depending on the individual’s constitution and condition, etc. Mycoplasma positive children may have Mycoplasma pneumonia or just an upper respiratory tract infection. If the child’s condition is mild and usually in good health, then the body resistance is strong and may only need to consume azithromycin for 3 to 5 days to get relief. However, if the child’s condition is more serious or the body’s immunity is poorer, then it may need to intermittently take 7~14 days or even longer to be cured. Azithromycin is a macrolide antibiotic, children may have gastrointestinal reactions such as nausea and vomiting after taking it, and it should be noted that azithromycin needs to be dosed according to the child’s weight, and should not be taken casually. Azithromycin is contraindicated in children who are allergic to it. Children with mycoplasma positive should be under the guidance of a doctor if they need to use medication, do not blindly use medication. In addition, if any abnormal symptoms occur in the process of medication, you need to consult a doctor in time to avoid accidents.
