According to the UNEP full report:

 "Ecological tourism and human settlements near caves and forested
areas, particularly those with poor housing conditions, can increase
human-wildlife contacts and human exposure to insects, ticks and other vectors of wildlife pathogens. "

I think ecotourism may need some guideline to decrease (not completely prevent) such risk of tourists and guides (In japan, mite's SFTS and bear attack are concerned).
