How long has mycoplasma pneumonia been contagious?

Mycoplasma pneumoniae cannot become infected if cured.

Halfway between bacteria and viruses, Mycoplasma pneumoniae is a facultative anaerobe, the smallest microorganism capable of surviving on its own, mainly through the respiratory tract. Healthy people inhale oral and nasal secretions from patients while coughing and sneezing, resulting in sporadic respiratory infections or mild epidemics. Mycoplasma pneumoniae is predominantly found in children and adolescents, and can be found in respiratory secretions from 2 to 3 days before the onset of illness to several weeks after recovery, so the infection period is still relatively prolonged.The main period of infection should still be 2 to 3 days before the onset of illness, as well as the febrile period. The contagiousness during this period should be strong, and it will be much weaker in the later stage, and it is itself a sporadic respiratory infection or a mild epidemic, and when the body's resistance is good enough, the probability of infection is not particularly high. Wearing a mask is key to preventing transmission from people living with Mycoplasma pneumoniae in the household.

Treatment of Mycoplasma pneumoniae includes anti-infective and symptomatic treatment. Because Mycoplasma pneumoniae does not have a cell wall, it is not susceptible to penicillin and cephalosporins. Its anti-infective therapy is focused on macrolides, tetracyclines, and fluoroquinolones. Azithromycin, doxycycline, levofloxacin and moxifloxacin are commonly used in clinical practice, and the course of treatment is generally 10~14 days, and in severe cases, it can be appropriately extended to about 3 weeks.

Symptomatic treatment mainly includes cough, expectorant, antipyretic, and treatment of complications. The prognosis for mycoplasma pneumonia is generally good, but the prognosis is worse in older patients and those with certain chronic diseases or central nervous system infections.Because Mycoplasma pneumoniae is somewhat contagious, it is necessary to isolate the respiratory tract to prevent infection of the surrounding population.

When a patient has a fever, if the temperature is not high, choose to use an antipyretic cream to help the patient reduce the fever. Antipyretic creams help patients dissipate heat but are not recommended for patients who are too young as this may causeHypothermia
