Uncomplicated fever

Very low urgency
Very common-

Body temperature higher than 38 °C that doesn't entail any risk for the organism.

Generally, it is secondary to an infection, although there are non-infectious causes that increase body temperature.

Fever is the main symptom, but sometimes it goes along with chills, feeling thirsty and general malaise.

It is diagnosed by ruling out other fever related causes.

Treatment consists solely of antipyretic medication and promoting the loss of body heat with physical measures (removing the clothing, wet cloths, a fan, etc.).
