Study on the integrated monitoring program regarding mouse and main mouse-borne disease in Zhejiang province / 中华流行病学杂志

ABSTRACT

Objective To study the integrated monitoring program regarding mouse and plague, hemorrhagic fever of renal syndrome(HFRS)and leptospirosis. Methods Integrated monitoring plan was used. A designated office coordinated 5 departments' actions within the Zhejiang Provincial Center for Disease Control and Prevention(CDC). Cage-trapping method was conducted to monitor the density of mice from June to October, respectively. Results Lishui municipal CDC had finished the integrated monitoring program on mouse and mouse-borne disease while the Longyou CDC had finished the field investigation, using the integrated monitoring program.Specimens were sent to provincial CDC. The integrated monitoring program needed more number of personnel and better coordination. Lishui reported 3 leptospirosis cases and 58 HFRS cases in 2009,with the incidence rates as 0.13 and 2.44 per 100 000, respectively. Longyou reported 2 leptospirosis case and 1 HFRS cases in 2009, with the incidence rates as 0.49 and 0.25 per 100 000, respectively.Lishui and Longyou had no plague case. Lishui caught 91 mice in 2009 and the density was 4.17%.Longyou caught 37 mice in 2009, with the density as 1.18 percent. Most mice caught from Lishui were Apodemus agrarius and the next was Mus musculus. In Longyou the Rattus tanezumi ranked the first, followed by Apodemus agrarius. The positive rate of HFRS antigen in Lishui and Longyou were 10.42% and 4.59% respectively. The positive rate of HFRS antibody in Longyou was 3.70%. The culture positive rate of leptospirosis in mouse renal of Lishui and Longyou were 0 and 0.98%respectively. The culture positive rate of leptospirosis in pig renal, duck renal, frog renal and cattle urine of Longyou was 0. The culture positive rate of leptospirosis in duck blood of Longyou was 80%.Conclusion The integrated monitoring program on mouse and mouse-borne disease seemed to be feasible and could promote the integrated surveillance and control program on mouse and mouse-borne diseases in China.
