How long is mycoplasma infection contagious?

Mycoplasma monycoplasma polydactylum infection, which is contagious, is most contagious in the initial 4-6 days of the disease, and the duration varies according to the length of the disease in each patient, generally disappearing after 3-5 weeks.

Mycoplasma pneumoniae is mainly transmitted through respiratory droplets, but it can also be transmitted through aerosols, and it is possible to become infected with prolonged close contact. After infection with Mycoplasma pneumoniae, the transmission through droplets is mainly 3-5 weeks after the illness, during which it is necessary to pay attention to isolation and protection, and avoid face-to-face unprotected communication, which can reduce the risk of infection. The population is generally susceptible to Mycoplasma pneumoniae and can occur in people of any age, with the highest incidence in people aged 5-20 years. Most patients with Mycoplasma pneumoniae infection present with tracheitis or bronchitis, some patients may have no symptoms, the infection is occult, and only a small percentage of patients present with symptoms of pneumonia. The clinical manifestations are fever, fatigue, sore throat, nasal congestion, runny nose, and muscle aches, which are characterized by intractable severe dry cough with no or small sputum, and some patients will have blood in the sputum.

Most patients with Mycoplasma pneumoniae infection have a good prognosis, but a small number of patients may develop pneumothorax, bronchiectasis, lung abscess, and even acute respiratory distress syndrome, which can be life-threatening. After the diagnosis is confirmed, patients need to be isolated for at least 3 weeks, especially if they are immunocompromised and children.
