A total of 117 deaths were recorded,resulting in an average annual mortality rate of 0.60/100 000 population. The highest average incidence was observed for other infectious diarrheal diseases（282.34/100 000）,followed by hand-foot-mouth disease（211.16/100 000）,hepatitis B（200.32/100 000）,tuberculosis（43.57/100 000） and influenza（43.30/100 000）.
