As fever is one of the manifestations of many diseases, the causes of high fever vary and there is a significant proportion of patients with high fever who cannot find the cause of their fever. Different departments are consulted for different illnesses. Most patients with acute fever often see the appropriate specialist based on the main discomfort that accompanies it.
A significant number of patients with first-episode fever are seen in emergency or infection clinics and are referred to a specialist for further confirmation based on certain test results. For specific types of infection, isolation in a TB clinic or a designated hospital for infectious diseases is required.
