- Fever of Unknown Origin

- ------------------------------------------------------------------------------

- QUESTION: We have a man working in our office who has been absent a lot
- recently because of a strange fever that defies diagnosis. We are all curious
- as to the nature of the disease, and more important, if there are any health
- risks for us. Do you have any advice for us, or clues to the nature of such a
- disease? you could help a lot of people by answering this question in your
- column.

- ANSWER: Occasionally the root cause of an illness can go undetected,
- especially if the diagnostic clues present are overlooked or misinterpreted.
- Fevers of unknown origin, or FUOs, are usually traced back to lymphomas,
- leukemias, or less frequently nowadays, internal infections within the body.
- Occasionally, interactions between medications can produce a FUO. In some
- cases, occupational causes are at the root of FUOs. Farmers or livestock
- workers can develop salmonellosis or similar infections, while fans of sushi
- and raw shellfish may acquire a fever-causing parasite from indulging their
- appetites.
- A very careful examination can help pinpoint the causes of almost all of
- these fevers. Subtle changes in skin condition often reveal important clues
- to a patient's health, as can inflammations or masses beneath its surface. A
- heart murmur can be an indication of endocarditis, particularly when the
- patient has had artificial valves implanted. Tuberculosis is a leading cause
- of FUOs, and tuberculin skin tests often reveal this condition. New imaging
- technologies such as computed tomography can reveal internal abscesses that
- would go undetected in the past; tissue biopsies generally confirm diagnoses
- first developed through such visual methods. The possibility of co-workers
- being at risk depends upon the exact diagnosis, of course, but overall I would
- consider your risks, as well of those of your co-workers, to be quite low.
