People who were raised around chickens, pigeons, and other birds in large
numbers often have a good resistance to histo as a result of being continuously
inoculated. Most of them never knew they were sick as the doses and reactions
were small but cumulative enough render them nominally immune to future
exposure. Carrizal has long been known as a histo habitat. There was a faded,
rusty sign posted on a building near the entrances--and that was 50 years ago.
My daddy raised chickens and pheasants when I was a kid and I've been in
Carrizal a dozen or more times without mask protection or obvious infection.
But we know from experience that not everybody can do that--they have gotten
sick. --Ediger

Gill thank you.
The situation is this.. The Secretary of Tourism create a project to use the
cave for tourism, they tender a project of ecotourism and sustainability in the
cave. A constructor win the tender.
The cave have an incident in the month of march, 25 people (teachers and
students scouts) are sick all of them. But the woman of SECTUR said she visit
there and not have fungus... They ask me if I can make a test, I said yes. the
Dr. Biologist from UANL Javier Banda and Sergi Gomez they will help me to do
this test.. The next week I will visit the cave with a security level 3 (is
high) to take some samples of soil and air, to send a laboratory.
With the result of that test, we can close the cave, if we don´t do that. They
can open the cave for tourism an is a bad idea.

Moni--I would suggest that you not visit Cueva de Carrizal and not take or send
anyone else there. There have been sufficient incidents of people getting
histoplasmosis to warn them there is a danger of contacting a lung fungus. Only
people with a known or demonstrated resistance to histo should visit that cave.
