The Histoplasmosis Caves Page
caves known or suspected of having transmitted Histoplasmosis to cavers
Caving remains among the safest of the adventurous avocations.
The dangers, including the biohazards, need to be taught
throughout the caving community. The medical profession needs instruction.
However the dangers need to be kept in perspective.
The listing of these caves does not mean that they are
inherently dangerous! It means that cavers visiting them should be aware of the
potential danger and consider protective equipment and their own susceptibility
to Histoplasmosis, and that of any caving companions. Anyone in the party who is
unfamiliar with Histo or the potential to contract it in these caves should be
informed before entering.

Histo Caves are divided into 3 totally arbitrary categories in this list:
Possibly Histo Contaminated - rumored cases
Probably Histo Contaminated - a few reported cases
Definitely Histo Contaminated - too many to have any
We are perfectly willing to accept changes to the status of any
of these caves.
