The disease was found each mouth throughout the year, marked with summer peak[38.46%(20/52)]. Patients increased year after year in summer and spring seasons(r = 0.92, P ＜ 0.01) .The disease was most commonly found in 30 - 59 age group[69.23%(36/52)];men women incidence ratio was 1.67: 1.00;farmers accounting for 94.23%(49/52).
