Prevalence of cutaneous reactions to the pine processionary moth (Thaumetopoea pityocampa) in an adult population.

Background: Thaumetopoea pityocampa [pine processionary moth (PPM)] is one of the most important lepidopteran agents causing urticant cutaneous reactions in humans in Mediterranean countries. This species is also expanding northwards, because of global warming.

Objectives: To investigate the prevalence, distribution by habitat group and possible risk factors of PPM cutaneous reactions in adults.
