Mycoplasma infections in children tend to have a long course and are usually cured in about 2 weeks if detected promptly and treated effectively. Mycoplasma is a class of minimal prokaryotic microorganisms that lack cell walls and can grow and reproduce in inanimate media, as distinct from bacteria and viruses. The average incubation period for mycoplasma infection is about 1-3 weeks, and there are no obvious clinical symptoms during the incubation period. Once a child is infected with mycoplasma, due to their poor resistance, there may be recurrent episodes, often with a runny nose, fever, colds and other manifestations, if not treated in a timely manner, it will become more serious, and the course of the disease is long and difficult to be suppressed in a short period of time. Mycoplasma infections do not work with ordinary anti-inflammatory drugs, so it is necessary to go to the pediatrician or emergency department in time to take targeted medication according to the child’s age, weight and condition. During the treatment period, the child should maintain a light diet, avoid seafood and meat, avoid greasy, spicy food, so as not to cause indigestion and other problems, so that the disease continues to worsen.
