Mycoplasma pneumoniae infection is usually endemic every 3-7 years, and the incidence of mycoplasma pneumonia can be as high as 30%-50% in peak epidemic years, with epidemics typically lasting 1-2 years. From the surveillance situation, the epidemic trend of Mycoplasma pneumoniae infection is expected to last from the end of 2015 to the beginning of 2017, and a high epidemic of Mycoplasma pneumoniae needs to be prevented in 2016. Persistent cough is the main manifestation of Mycoplasma pneumoniae Mycoplasma pneumoniae is one of the important causative agents of respiratory infections in children. The characteristics of Mycoplasma pneumoniae infection are not obvious, the clinical symptoms are mild, persistent somewhat like whooping cough, which lasts longer, and older children will have chest pain, etc., and some other sexual manifestations, such as joint pain, rash and other symptoms that parents can see. Severe infections can cause neurological and cardiovascular multi-system complications and can lead to death in severe cases. For children with respiratory infections, laboratory tests such as Mycoplasma pneumoniae specific pathogen, antibody and nucleic acid monitoring, and genetic tests can be done to confirm the diagnosis. Confirmatory tests can be done if there are 2-3 respiratory infections in a month. Frequent hand washing helps prevent Mycoplasma pneumoniae infections Currently, azithromycin and clarithromycin are used to treat Mycoplasma pneumoniae infections. If the treatment is not complete, the infection will recur. In terms of home prevention, Sun Hongmei suggests: as Mycoplasma pneumoniae is mainly droplet transmission, diligent hand washing has a better preventive effect on Mycoplasma pneumoniae. Pay attention to air circulation and don’t stay with infected children. In daily life, try to: 1, reduce contact, less take children to crowded occasions, if you go, it is recommended to wear a mask; 2, diligent hand washing with soap, go out and come back, according to the correct washing method hand washing; 3, while washing exposed parts, such as rinsing the mouth, washing the nasal cavity, eyes, etc., to reduce the chances of infection. When a child has recurrent respiratory infections within two to three months, he or she should go to the hospital immediately for Mycoplasma pneumoniae testing. 2, when the diagnosis of Mycoplasma pneumoniae infection is confirmed, complete the treatment course under the guidance of the doctor, do not take the principle of “stopping the medication when the child’s fever goes down and the cough gets better”, as it is easy for the infection to recur. If children experience gastrointestinal reactions, such as nausea, vomiting, or mild abdominal pain, during the medication period, no special treatment is needed.
