Investigation on knowledge of malaria prevention and control in residents of Suining County / 中国血吸虫病防治杂志

Objective To understand the status of knowledge of malaria prevention and control in residents of Suining Coun-ty,so as to provide the reference for improving the implementation of malaria elimination. Methods Nine villages in 3 townships (3 villages per township)were randomly selected as the study areas,and 200 residents aged above 15 years of each village were in-vestigated with questionnaire for the knowledge of malaria prevention and control. Results The awareness rates of“malaria trans-mission way”,“main symptoms of malaria”,“life-threatening of falciparum malaria”,“how to treat malaria”,and“how to pre-vent malaria”were 96.27%,95.01%,81.46%,98.19%and 96.27%,respectively. There were no significant differences between the different genders and among the different areas (all P>0.05),but there were significant differences among different age groups(all P<0.05). Conclusion The awareness of malaria prevention and control in residents of Suining County is relatively high,which means the health education is effective.

Analysis of malaria prevalence in national malaria surveillance sites of Jiangsu Province / 中国血吸虫病防治杂志

Objective To understand the current status of malaria prevalence,its impacts and malaria transmission trends in Jiangsu Province.MethodsThe malaria incidence,and its symptoms,mosquito preventive measures,Anopheles density,mosquito biting rates and related factors were investigated in malaria epidemic villages as surveillance sites such as Guanshan Town of Suining County,Tangzhang Town of Tongshan County,Tianganghu town of Sihong County,Qiuji Town of Xuyi County and Zhangzhu Twon of Yixing City.ResultsIn 2006,the bednet coverage was 20.29% and bednet-using rate was 34.32% in 27903 residents of 7921 households of 15 administrative villages.In 2005,750 Anopheles sinensi were captured from 50 bednets in the early morning,the human biting ratio was 0.17/person per night,and in 2006,1927 Anopheles sinensi were captured from 50 bednets in the early morning,human biting ratio was 0.38/person per night.The average blood smear checking rate was 2.72%(6089 people)and the average positive rate was 0.48%(29 plasmodium positive individuals).ConclusionThe lower blood smear microscopy testing,few positive rates of febrile patients and increased Anopheles sinensis density were the main factors of malaria relapses in the area of the North Huaihe River in Jiangsu Province.
