Many children have had mycoplasma infections and often appear positive for antibodies to Mycoplasma pneumoniae. The parents are worried about this repeatedly, why this disease can not go to the root? In fact, mycoplasma pneumoniae infection is tested for antibodies to mycoplasma pneumoniae, not the pathogen itself, and antibodies generally last three to six months in the body, that is, if you have had a mycoplasma pneumoniae infection, after six months or so, in time without mycoplasma infection, the test may also be positive. The current expert consensus is that mycoplasma infections can heal on their own, provided there is sufficient time, effective care, and no complications. Therefore, when a child is tested positive for Mycoplasma pneumoniae antibodies for the second time, it is only recommended to use medication according to the severity of the child’s specific symptoms, rather than long-term oral or intravenous macrolide use.
