The symptoms of fever and wheezing are often associated with infections of the lower respiratory tract, such as bronchitis or pneumonia, which are often serious. The first thing you need to do is to take your temperature and have a chest radiograph, and preferably a routine blood test and a test for mycoplasma antibodies. If there is an increase in white blood cells in the routine blood test, it means that it is a bacterial infection that causes bronchitis or pneumonia, which can be treated with intravenous medication, such as ceftriaxone. If the infection is viral, it can be treated with intravenous Xiyampin. If the infection is mycoplasma and there is a positive result for mycoplasma antibodies, treatment with azithromycin is required. In addition, for the symptoms of coarse wheezing, it is best to relieve the symptoms with nebulized inhalation medications, such as budesonide and terbutaline. If the body temperature is high, above 38.5°C, antipyretic medications, such as ibuprofen suspension, are also needed to relieve symptoms.
