2 year old half child has a fever 3 days still do not retreat how to do

Suggestion: Family members need to actively check the baby's temperature during fever, or take him to the hospital for examination to determine the cause of fever. Usually family members need to actively control the baby's temperature through physical or drug control. If the fever is caused by bacterial infection, actively use antibiotics. If the fever is caused by viral infection, the child needs oral antiviral treatment.
