A 12-year-old boy with fever can take oral aminocarbophosphate capsules. If the body temperature is relatively high, over 38.5°C, you can take oral ibuprofen suspension for symptomatic treatment, while drinking more water, taking vitamin C supplements, and paying attention to rest to prevent cross-infection and complications. Physical cooling can also be used, such as swabbing the forehead, armpits and groin with warm water to maintain a good surrounding environment. If it is caused by a virus, symptomatic treatment with antiviral drugs, such as ribavirin pellets, is usually given. If it is caused by an epidemic virus, oseltamivir phosphate can be given as symptomatic treatment. If it is caused by bacteria, antibiotics can be given to treat symptomatically, such as penicillin and cephalosporins. If the cold is caused by wind-cold, give Jing Fang Da Xie Tang plus or minus; if the cold is caused by wind-heat, give Yin Qiao San plus or minus. If the child is in a worse condition with coughing symptoms, it is recommended to consult a pediatrician.
