If a child has a fever and then gets red dots on his face, it is likely that the fever is caused by an emergency rash in younger children. Often the red dots are not particularly severe, with mild itching or no itching, and usually appear after 3-5 days of fever when the body temperature suddenly drops and the red dots appear. If there are no serious complications, such as viral encephalitis or impairment of lung function, the dots may dissipate on their own after 2-3 days. They can be treated with certain antiviral drugs such as interferon and ribavirin. Generally the fever is also heavy, in most cases it will exceed 39 degrees, or even 40 degrees, you must take antipyretic drugs to lower the body temperature, otherwise for the child, it is easy to lead to hyperthermia convulsions, it is recommended to take oral acetaminophen granules or ibuprofen suspension.
