Mycoplasma pneumonia strikes, how to deal with it daily？

　　Reading tips

　　Mycoplasma pneumonia mostly occurs in autumn and winter, and there are sporadic cases in other seasons. At the initial stage of infection, the symptoms are similar to those of the common cold, which should be comprehensively judged according to the onset time, clinical symptoms, physical examination, imaging examination and pathogenic examination.

　　Recently, mycoplasma pneumonia has aroused concern, and most of the patients infected with mycoplasma pneumonia in hospitals across the country are children. The disease control departments in Beijing, Shanghai, Jiangsu, Shaanxi and other places all issued reminders, and there was a peak in pediatric clinics.

　　The reporter found that the number of outpatient and emergency departments in many hospitals in Beijing has increased to varying degrees. Most of the patients are children, but many adults have been recruited. Xu Baoping, director of the Department of Respiratory Medicine of Beijing Children’s Hospital, said that since September, the number of daily outpatients in the fever and cough clinic of Beijing Children’s Hospital has increased, and about 20% of the children tested positive for mycoplasma pneumoniae. In autumn, other pathogens such as respiratory syncytial virus, influenza virus, rhinovirus, adenovirus and other infections have also increased.

　　Mycoplasma pneumoniae can be repeatedly infected.

　　The reporter learned from Chaoyang Hospital in Beijing that mycoplasma pneumonia (MPP) refers to pulmonary inflammation caused by mycoplasma pneumoniae (MP) infection, which can involve bronchi, bronchioles, alveoli and interstitial lung. Mycoplasma pneumoniae pneumonia is the most important community-acquired pneumonia in children aged 5 and above in China.

　　Mycoplasma pneumonia mostly occurs in autumn and winter, and there are sporadic cases in other seasons. Some people think that the prevalence rate of children under 5 years old is low, but it is not uncommon for young children to be infected.

　　Mycoplasma pneumoniae is divided into many categories, with fever and cough as the main clinical manifestations, which may be accompanied by headache, runny nose, sore throat and earache. Fever is mainly moderate to high fever, and persistent high fever indicates serious illness. Cough is more severe, which can be similar to whooping cough. Some children have wheezing, especially infants. The early signs of the lungs may not be obvious, and with the progress of the disease, there may be a decrease in breathing sounds and dry and wet rales.

　　Mycoplasma pneumonia is contagious. It can be transmitted by droplets and direct contact, and it can be repeatedly infected. It is not always immune once. Experts remind that if there are two or more babies at home, they need to be isolated.

　　Because Mycoplasma pneumoniae can affect both upper and lower respiratory tract, when the upper respiratory tract is initially infected, there are symptoms similar to the common cold, such as stuffy nose, sore throat and fever. Whether you are infected with mycoplasma pneumoniae and whether the infection progresses to pneumonia needs to be comprehensively judged according to the onset time, clinical symptoms, physical examination, imaging examination and pathogenic examination.

　　Dong Xiaoyan, director of the respiratory department of Shanghai Children’s Hospital, said that if school-age children have symptoms of respiratory infection, persistent fever and aggravated cough during the epidemic season of mycoplasma pneumoniae, parents should be especially vigilant, and there may be mycoplasma pneumoniae infection. If the child is clearly infected with mycoplasma pneumoniae, and there are persistent high fever, listlessness, cough with vomiting, etc., it is necessary to seek medical attention in time.

　　There are more children with mycoplasma pneumoniae infection this year than in previous years.

　　Cao Ling, director of the Department of Respiratory Medicine of the Capital Institute of Pediatrics, said in response to the media that the high incidence of mycoplasma pneumoniae infection is from August to December every year in Beijing, and it usually reaches its peak around November every year. However, as far as this year’s situation is concerned, it is hard to say when the future summit of mycoplasma pneumoniae infection will occur. There are indeed more children infected with mycoplasma pneumoniae this year than in previous years, mainly concentrated in school-age children.

　　With the high incidence of mycoplasma pneumonia in children, there are more patients with mycoplasma pneumonia in adults. It is reported that a 32-year-old patient with mycoplasma pneumonia was admitted to the Department of Infectious Pulmonary Diseases of Ningbo Hospital of Traditional Chinese Medicine recently. While he was hospitalized, the children at home were also hospitalized, and a family of three people were recruited one after another.

　　Sun Minghuan, an attending Chinese physician in the Department of Infectious Pulmonary Diseases, reminded that Mycoplasma pneumoniae is contagious. When someone at home has symptoms such as fever and cough, he should see a doctor as soon as possible, and his family should be well protected to avoid infection.

　　Adults who stay with children infected with mycoplasma pneumoniae for a long time are still not to be underestimated. Dr. Sun Minghuan said that the susceptible population of mycoplasma pneumonia is children and adolescents, but recently, the number of adult patients with mycoplasma pneumonia admitted to them has also increased significantly compared with the past. Like mycoplasma pneumonia in children, mycoplasma pneumonia in adults is characterized by fever and cough, which may be accompanied by symptoms such as headache, runny nose, sore throat and earache. Cough is more severe and paroxysmal dry cough is more common.

　　How do parents deal with mycoplasma pneumonia?

　　Does mycoplasma pneumoniae positive mean that you have mycoplasma pneumonia? Zhang Yu, a researcher at China Center for Disease Control and Prevention, wrote that, in fact, mycoplasma pneumoniae positive and mycoplasma pneumonia are two different things.

　　The result of mycoplasma pneumoniae test is positive, suggesting that the pathogen may be infected, but the infection cannot be 100% confirmed. Detection methods of mycoplasma include PCR detection of nucleic acid and ELISA detection of antibody. Mycoplasma pneumoniae positive generally means antibody positive. There are two kinds of mycoplasma antibodies: IgM antibody and IgG antibody. If IgM antibody is positive, it indicates acute infection; If only IgG antibody is positive, it suggests that mycoplasma pneumoniae has been infected. In addition, any clinical detection method has a certain false positive rate. Therefore, a positive antibody test does not mean that you are infected with Mycoplasma pneumoniae.

　　Regarding whether mycoplasma pneumonia can cause "white lung", professionals said that mycoplasma pneumonia may bring mucus plugs to block the bronchi, which in turn will cause "atelectasis", that is, the air content of the lungs will be reduced, resulting in "white lung" in imaging. But this is two concepts with the "white lung" of diffuse lesions in both lungs.

　　By tapping the back to expel phlegm, eliminating phlegm with drugs, bronchoscopy and other means, the child can be cured in a short time, and basically will not cause life-threatening. Most children with mycoplasma pneumoniae infection have a good prognosis. Children with severe and refractory mycoplasma pneumoniae infection may leave lung structure or function damage, which requires long-term follow-up.

　　How to prevent mycoplasma pneumoniae infection? Experts say that in daily life, we should first ventilate more and gather less. At ordinary times, it is best to open the window and ventilate 2 to 3 times a day at home for 15 to 20 minutes each time. Avoid taking children to crowded and poorly ventilated public places in the near future. Secondly, we should maintain good personal hygiene habits, wash our hands and rinse our mouths frequently. Appropriate outdoor activities, pay attention to physical exercise, and ensure adequate rest time. In addition, clothing should be appropriate, and clothing should be increased or decreased in time when the climate changes, with warm hands and feet and no sweat.
