The characteristics of fever due to mycoplasma infection, which often results from infections of the respiratory and reproductive tracts, typically manifest as mild to moderate fevers. In some infants and young children, due to imperfect temperature regulation, high fevers may occur. Blood tests generally show normal white blood cell counts. Imaging can reveal lung infections, and tests for mycoplasma pneumonia antibodies are positive. The cough commonly associated with mycoplasma infections is usually an irritating, dry cough, with little sputum production.
