The fever that occurs in children with mycoplasma infection usually occurs for 1-3 weeks, with most around 2 weeks. The degree of fever varies, with some children having a high fever, some having a moderate fever, and some having a low fever. At the beginning of mycoplasma infection, the child will show some signs of discomfort, such as general weakness, headache, or other uncomfortable signs. Therefore, it is important to take regular treatment for mycoplasma infections. If the temperature remains high, or if there are other clinical symptoms, such as increased cough, dyspnea, chest pain, etc., care must be taken to avoid the development of severe mycoplasma pneumonia. For fever, it is important to observe temperature changes and the presence of clinical comorbidities. Parents should pay high attention to this because mycoplasma infection can cause a certain epidemic. If the symptoms of fever appear and the child is still bent on going to school, it will affect other children, so it is important to seek early medical attention.
