There is a constant range of body temperature in the human body, of which infants and children are no exception. The normal body temperature is below 37.3 degrees Celsius, using the axillary temperature as a method of detection. When your child’s body temperature exceeds this value, you should consider that your child has a fever. Of course, you need to pay attention to some methods when measuring, for example, mercury thermometer is more accurate, but you must pay attention to safety. The temperature of the ear thermometer is often affected by the ambient temperature and requires repeated measurements and a stable room temperature, etc. The first thing to consider is whether there is an inflammatory infection. Since children’s resistance is weak, they are susceptible to viral invasion that can lead to inflammatory infections, and inflammatory infections are prone to give children a low fever when they appear. Some children have a low fever, parents feel that it is not serious, and even think that “the fever is not high will not burn”, and delayed for a long time not to consult, in fact, the child low fever is not less important than a high fever, low fever may also be bacterial infection requires antibiotic treatment, delayed low fever may even be a serious disease. Therefore, as long as your child’s temperature exceeds this value, or always hovers around this value, whether it is a low fever or a high fever, it is recommended to help your child find the cause of the low fever and take timely measures to treat it.
