What should I do if my child has a high fever?

What should the baby do if he often has a fever and does not return? If the baby has a fever repeatedly, the common cause is fever caused by infection. The common causes of fever caused by infection are virus, bacteria, mycoplasma, chlamydia, rickettsia, mold or other parasitic infections, which can cause the baby to continue to have fever. At this time, we must find out the reason in time. In addition, other non-infectious factors, such as blood system diseases, leukemia, connective tissue diseases, rheumatic fever and other malignant tumors, can also cause the baby to continue to have fever, which is relatively rare. Infectious factors are common. At this time, it is necessary to observe whether there are other complications when the baby has a fever, such as cough, diarrhea and urine color change. Go to the hospital for examination in time, and go to the hospital for examination to make clear the cause and diagnosis. Give the baby a simple blood routine and mycoplasma anti-inflammatory antibody test. If the baby is complicated with other symptoms and cough, you can do the corresponding chest X-ray examination. In addition, if the baby is complicated with diarrhea, it may be a fever caused by intestinal infection, and routine examination can be done. In short, there must be a reason why the baby doesn't have a fever. It is best to go to the hospital in time for corresponding examination and take appropriate treatment.
