How long does it take to be treated for a weak positive for Mycoplasma pneumoniae in children

Weak positive Mycoplasma pneumoniae in children generally requires treatment for 1~2 weeks. If Mycoplasma pneumoniae infection is weakly positive, it means that the child's degree of infection is not particularly high. Even if the expression is weakly positive, it is necessary to retest, and if the antibody test for Mycoplasma pneumoniae is retested after a week, the test result changes from a weak positive to a positive, or even a strong positive, in such a case, it is necessary to increase the course of treatment appropriately. If the result of the retest shows that the weak positive antibody test disappears after a week, it means that the treatment effect of anti-mycoplasma has made good progress, and the course of anti-mycoplasma treatment at this time can be appropriately shortened. Mycoplasma is susceptible to tetracyclines and macrolide antibiotics, with erythromycin as the preferred drug at a dose of 30 mg/kg 61 days orally three times a day, which improves clinical symptoms, reduces lung opacity, and shortens the duration of the disease. Erythromycin treatment is 2~3 weeks. In addition, mecarmycin, rifampicin and acetylspiramycin are also effective. Adrenocorticosteroids may be added to severely ill children.
