In addition to measuring the child’s temperature, the following should be noted. First, pay attention to the mental condition of the child If the child is in good spirits, it suggests that the infection is mild. If the child’s spirit is good, the infection is mild. If the child is in poor spirits, lethargic, and has a yellowish or dark complexion, the infection is usually serious. For example, in toxic dysentery, the main manifestation of the child is a bad color, poor spirit, may only have nausea and vomiting symptoms, not diarrhea, but the condition is serious, it is easy to combine with toxic shock. Second, the face, trunk with or without rash and bleeding points Many viral infections will appear in the early stage of the rash, such as chickenpox, rubella. The rashes that appear during fever are scarlet fever, measles and so on. If bleeding spots appear in the early stage of fever, we should except epidemic meningitis. Third, the presence of diarrhea and urine If the child has diarrhea, ask whether the diarrhea occurs before the fever or after the fever. Appear before the fever or fever appeared within 1 day, suggesting that the child intestinal infection; if the fever appeared a few days after the fever, it may be a comorbidity or an adverse reaction to drugs. For fever with obvious diarrhea, especially mucus, pus and blood stools, suggesting intestinal bacterial infection, it is best to use a cardboard box or plastic bag to collect stool samples with pus and blood or mucus when going to the hospital, so as to facilitate laboratory tests. Stool in the diaper cannot be used as a specimen for examination. At the same time, we should also pay attention to the child’s urine has no abnormal color, if the fever at the same time soy sauce-colored urine, it means that the child has the appearance of hemolysis, suggesting that the condition is serious. Fourth, whether accompanied by obvious abdominal pain for abdominal pain is obvious, especially can not walk straight back, or abdominal pain does not allow rubbing the stomach, we should consider appendicitis. Because the symptoms of appendicitis in children are sometimes atypical, easy to perforate and combined abdominal infection. Pay attention to the epidemiological situation Note whether there are similar diseases around, especially during the epidemic of some infectious diseases, such as hand, foot and mouth disease. If a child is surrounded by children with the disease, and the child has a rash or blisters on the mouth, throat or hands and feet, even if the symptoms are atypical, it is important to consider hand, foot and mouth disease.
