Methods Data of disease and population were analyzed by descriptive epidemiological methods. Results From 2001 to 2007,380 cases of ECM were reported,including 18 deaths with the annual incidence of 1. 01/100 000 and case fatality of 4.74%. The annual mortality was 0. 048/100 000. The area with the highest incidence was rural, and the second was city and the third was pasture. Most of cases occurred from February to April （64. 21% ） . The three age groups with higher incidence were 5 -9 years （2.24/100 000） ,0 -4 years （ 1.76/100 000） ,10 - 14 years （ 1.00/100 000）. Most of the patients were students （59.11%）. Conclusion ECM in Qinghai province was highly sporadic with obvious seasonal variation. Majority of the cases were under age of 15 years. The occurrence of Nm A was the main prevalence strain.
