Abstract:

Objective To analyze the epidemic trend of Japanese encephalitis(JE) in 1991-2010 in Inner Mongolia, providing scientific theory for the prevention and control of JE. Methods JE surveillance data from 1991 to 2010 were analyzed by descriptive epidemiology. Results Two hundred and sixty-two cases of JE were reported with an average incidence of 0.059/105 from 1991 to 2010. Thirty-four cases died of the epidemic with an average death rate of 0.008/105 and an average mortality of 12.98%. JE cases came from 10 of all the 12 cities (leagues) of the Region, and Tongliao city, located in the east Inner Mongolia, saw 186 cases, which accounted for 70.99% of all the JE cases. 257 cases of JE were reported from July to December constituting 98.09% of the total. Children and young adults were affected most by JE, 106 cases being peasants accounting for 40.46%. Conclusion The strategy for the prevention and control of JE worked very well. It is suggested that adults be immunized with JE vaccine for the prevention of the epidemic.
