[To investigate the relationship of airborne fungi and allergic disease of respiration system in the city of Wuhan region].

Objective: To investigate the relationship between the prevalent species and the seasonal drift law of airborne fungi and respiratory allergic disease in the city of Wuhan.
Method: Airborne fungi was investigated by exposed sides from 2007 to 2008, and 1674 patients with respiratory allergic disease that were used to do allergens skin test simultaneously, in order to analyze the simultaneous.
Result: Airborne fungi could be detected in air all over the year. In 2007, the exposed films collected 26 734 fungi spores, and 686 other fungi (hypha and not well known fungi), to the sum of 27420. Otherwise, in 2008, the exposed films collected 26 531 fungi spores, and 730 other fungi, to the sum of 27 261. In the survey, 17 types of species of the collected fungi spores were identified, and the predominant species were alternaria sp, ustilaginales, deightoniella sp, uredinales, and the quantity of Fungi alternaria was most of all . And the peak period mainly concentrated from April to June, and from September to October. Otherwise, the positive rate of fungi skin test in patients with respiratory allergic disease was 10.48% in 2007, but 10.07% in 2008. The main period of onset of respiratory allergic disease was from April to June, and from September to October, similar as the seasonal drift law of airborne fungi.
Conclusion: The period of onset of respiratory allergic disease was consistent with the seasonal drift law of airborne fungi.
