The following measures can be used to deal with a 2-week-old baby who has been running a fever. First of all, a puncture and bloodletting can have a good antipyretic effect, especially on the tips of the child’s fingers or on the tips of the ears, especially for fevers caused by heat toxicity. Secondly, children can be treated with cephalosporins. If the fever is caused by bacterial infection, cephalosporins should be used to fight the infection. If the fever is caused by Kawasaki disease, the fever will persist and will subside soon after the application of gammaglobulin.
