Fever in Adults (cont.)

Is Follow-Up Necessary After Treatment of a Fever?

Most fevers will go away in a few days with the appropriate treatment. It is important to follow up with a health care professional to be sure the cause of the fever is treated correctly. This may be done in a few days to weeks after the initial visit, depending on the cause.

If symptoms worsen, if the fever continues for more than three days despite treatment, or if the fever lasts longer than a week without treatment, see a doctor immediately.

Follow-up is very important especially for people with fevers due to cancer, drug-induced fevers, infectious causes like tuberculosis, FUOs, or hormone problems, since these people may experience relapses and repeated treatments. In some cases, hospitalization may be required.

Is It Possible to Prevent Fever in Adults?

Most fevers come from an infection. Individuals can help prevent the spread of infection and thus prevent fever.

  • The best way to prevent the spread of infection is to wash the hands frequently and avoid touching the face or mouth as much as possible.
  • Keep the home and work environment clean.
  • Avoid direct contact with sick people.
  • Do not share cups or utensils, towels or clothing, especially if they are not clean.
  • Wear appropriate protective clothing and equipment when working with animals.
  • Make sure immunizations are current and get the appropriate preventive medication and immunizations when necessary if traveling to another country.
  • Do not use illegal drugs.
  • During strenuous exercise, stay well hydrated, wear cool clothing, take frequent breaks, and cool down after the workout. Avoid use of alcohol and drugs that can alter behavior and judgment, and don't prevent a person from seeking shelter from the heat.
