Recently, many hospitals across the country have seen more patients infected with Mycoplasma pneumoniae, mostly children.

What is mycoplasma? What age children are easy to get? Will adults also get it? Now let's take you to reveal the secrets of Mycoplasma pneumoniae one by one!

What is mycoplasma pneumoniae?

Mycoplasma pneumoniae is a kind of microbe between bacteria and virus, which is the smallest microorganism known to exist independently in the world. Mycoplasma pneumoniae has no cell wall structure, like bacteria without "coat". 75% alcohol and chlorine containing disinfectant (such as 84 disinfectant) can kill mycoplasma pneumoniae.

Mycoplasma pneumoniae is an important pathogen of acute respiratory infection in Beijing. Mycoplasma pneumoniae can be divided into two subtypes, type I and type II. At present, the main prevalent subtype in Beijing is type I.

The population is generally susceptible to Mycoplasma pneumoniae, but it mainly occurs in children and adolescents over 5 years old.

Mycoplasma pneumoniae infection can occur throughout the year. The high incidence period of Mycoplasma pneumoniae infection in Beijing is from August to December every year, and it usually reaches its peak in November every year.

How is mycoplasma pneumoniae transmitted?

Mycoplasma pneumoniae infected patients and asymptomatic infected persons are the main source of infection. The incubation period is 1-3 weeks, and the infectious disease can be found from the incubation period to several weeks of symptom relief.

Mycoplasma pneumoniae is mainly transmitted through droplets, and can be carried in the secretion when coughing, sneezing, and running nose.

What are the symptoms of mycoplasma pneumoniae infection?

The main symptoms of mycoplasma pneumoniae infection are fever, cough, etc. The cough is usually severe, and may continue for 1-2 weeks after the fever subsides.

Mycoplasma pneumoniae infection can cause upper respiratory tract infection, lower respiratory tract infection such as pneumonia, and extrapulmonary complications such as autoimmune hemolytic anemia.

Mycoplasma pneumoniae is one of the main pathogens causing the high incidence of pneumonia in autumn and winter in Beijing. Mycoplasma pneumoniae pneumonia generally belongs to interstitial pneumonia, so the clinical signs are often lighter than the results of imaging examination, and after the clinical symptoms disappear, lung imaging examination may also have inflammatory manifestations.

Since Mycoplasma pneumoniae has no cell wall, the familiar penicillin and cephalosporin antibiotics all target the cell wall, so they are completely ineffective against Mycoplasma pneumoniae.

Macrolide antibiotics, such as roxithromycin and azithromycin, are currently the first choice for treatment of mycoplasma pneumoniae infection.

Therefore, if a citizen friend has fever accompanied by severe cough, he or she should seek medical advice in a timely manner, find out the cause of the disease as soon as possible, standardize treatment, and never use drugs blindly.
