Usually, when we talk about mycoplasma infection, we are mainly referring to mycoplasma pneumonia, an inflammation caused by the infection of the lung tissue and bronchi by mycoplasma. This condition is collectively known as mycoplasma pneumonia. Mycoplasma pneumonia often starts slowly. Some people may experience an irritating cough, producing a small amount of white, sticky phlegm, along with fever, headaches, and even muscle soreness throughout the body in some cases. In most cases, mycoplasma pneumonia can be cured; the body’s immune system can overcome it. However, the severity may increase when the body’s immune functions are impaired. Moreover, mycoplasma pneumonia is contagious. If an infection is confirmed, isolation is necessary, and attention should be given to ventilating and disinfecting the room.
