How sick can orchid growing make us?

[Miamiheat]

Hi,
Absolute beginner here but i picked up your thread and read it with great interest. I am already experiencing the worries and joys of the hobby. My job has been very stressful this year and i found in the orchids an incredible relief: i get home and i am in a different world (a jungle like my girlfriend says). Anyways as a beginner i ignore most of the dangers you experienced growers might have faced. I had no idea it was possible to contract fungal infections from the plants so I am very curious and would like to suggest that a thread or sticky be put in the beginner section regarding those risks as I am sure a lot of the beginners are totally unaware of such things.
thank you for the information.
