Objective To analyze the results of malaria surveillance in Huai’an District in the recent 5 years,so as to pro-vide the evidences for the establishment of suitable control strategy in the district. Methods The febrile patients among perma-nent and floating populations in Huai’an District from 2009 to 2013 were examined by immunity and etiology methods and the mos-quito vector in this district were investigated. Results In recent 5 years,a total of 48 203 person-times among permanent popula-tion were examined,and no positives ones were found,and totally 360 person-times among floating population were examined, and 53 cases of malaria were detected,including 2 vivax malaria cases,48 falciparum malaria cases and 2 undifferentiated cases, and the positive rate of the floating population was 14.72%. All the cases were exported workers infected in Africa and Southeast Asia. A total of 1 048 Anopheles sinensis mosquitoes were captured in 2003,no other Anopheles mosquitoes were found. Conclu-sions In recent 5 years,no local malaria cases have been found in Huai’an District,but the imported cases increase,and more-over,the mosquito vector and the transmission condition of malaria still exist.

Objective To understand the awareness status on malaria control knowledge of residents,primary and middle school students in Huai’an District,Huai’an City,so as to provide the evidences for promoting the malaria elimination process in this district. Methods Three towns in Huai’an District were selected randomly,and one village,one primary school and one junior middle school in each town were chosen as the investigation sites. The residents over 18 years old,the primary school students in Grade 4 to 6,and the junior middle students in the investigation sites were investigated by questionnaires to under?stand their awareness status on knowledge of malaria control. Results Totally 305 residents and 618 students were investigated. The awareness rate of students was 89.97%,and the rates of the junior middle school students and primary school students were 85.94%and 94.10%,respectively,the difference between them was statistically significant(P<0.01). The awareness rate of the residents was 80.98%,which was lower than that of the students(P<0.05). For the students,the awareness rate on“pre?caution of malaria”(96.74%)was the highest,while that on“drug of malaria”(68.93%)was the lowest. For the residents,the rate on“transmission route of malaria”(95.08%)was the highest,that on“4·26 is Malaria Day”(64.26%)was the lowest. Ex?pect the items of“transmission route of malaria”and“precaution of malaria”(both P>0.05),the differences of the awareness rates on all the other items between the students and residents were statistically significant (all P<0.01). Conclusions Al?though the awareness rates of malaria control knowledge in the population of Huai’an District,Huai’an City have achieved the goal of the relevant requirement,the health education on malaria control still should be strengthened,especially for the primary students,female residents and exported labor service personnel.
