Most of the fevers caused by mycoplasma infections in children generally have the following patterns. First, the temperature of the fever is high, because mycoplasma infection causes mycoplasmaemia, which causes a high fever, mostly above 39°C in the armpits of children. Secondly, the fever lasts longer because mycoplasma infection not only causes mycoplasmaemia, but also causes a strong immune response, which causes the fever to last longer. For fever caused by mycoplasma infection in children, it is necessary to apply erythromycin and other medications in a timely manner.
