Objective To analyze the surveillance situation of epidemic encephalitis B from 2010 to 2014 in Heze city. Providing scientific basis for treatment and control of epidemic encephalitis B. Methods The data for analysis is based on epidemic encephalitis B management system,epidemiological case study and laboratory diagnosis. Results A total of 62 epidemic encephalitis B cases were reported during 2010 to 2014. The incidence of epidemic encephalitis B from 2010 to 2014 was 0. 49 /100000,0. 034 /100000,0. 065 /100000,0. 098 /100000 and 0. 009 /100000 respectively and showed obvious decreasing trend. 62 epidemic encephalitis B cases were distributed in 61 administrative villages of 49 towns among 9 counties in Heze city,relatively concentrated and highly sporadic appearance. The case timely investigation rate and timely follow- up rate were both 100%. The collected rate of serum samples and Ig M positive rate of serum was 80. 65%,96. 00%respectively; the collected rate of cerebrospinal fluid specimens and Ig M positive rate of cerebrospinal fluid was48. 39%,90. 00% respectively; serum specimens collected rate was 61. 29%,positive rate was 84. 21%. laboratory diagnosis rate was 77. 42%. Conclusions Work of treatment and control of epidemic encephalitis B of Heze city has made a great progress,but still has shortcomings. Vaccination and monitoring of epidemic encephalitis B still should be strengthened and efforts are still needed for treatment and control of epidemic encephalitis B.
