To analyze malaria situation and evaluate the effect of control program in Henan Province during 1990-2005.
Data were collected and analyzed on the measures and effects of malaria control, vector surveillance, blood examination for cases with fever and serological surveillance in the province during 1990-2005.
In the 16 years, a total of 802,700 people were given pre-transmission season treatment with chloroquine and primaquine for a radical cure of vivax malaria, chemoprophylaxis was given to 764,300 people at high risk during the transmission season, treatment or presumptive treatment was given to 43,891 cases. 11,216,100 cases with fever were tested and 11,213 (0.10%) were found positive accounting for 29.01% (11 213/338 654) of all malaria cases. A total of 1 332 800 bed nets were treated with insecticide and 1,999 300 people were protected in 1990-1992 and 1996-1999. 34,846 residents including pupils were tested with IFAT in 1990-2000 and 1149 (3.30%) were positive. The parasite rate amongst 71,234 local residents including pupils was 0.40% (286/71,234). The principal transmitting vectors were Anopheles sinensis and An. anthropophagus. The man-biting habit for An. sinensis and An. anthropophagus was 0.0608 and 0.3143 respectively, and the vectorial capacity of An. anthropophagus was 22.4 times higher than that of An. sinensis. In this period, 38,654 malaria cases were reported in the province and the annual malaria incidence was 2.62 per hundred thousand, the lowest annual incidence was in 1992 (0.37 per hundred thousand). 70.05% (27,076/38,654) of these malaria cases were from areas where An. anthropophagus was present.
In general, the malaria control activities have been effective and the epidemiological situation kept stable in Henan Province, although in some areas the situation is unstable and outbreak spots or focal epidemics occur.
分析1990 - 2005年河南省疟疾疫情状况并评价防治措施效果。
收集并分析1990 - 2005年河南省疟疾防治措施、效果、媒介监测、发热病人血检及血清学监测等资料。
16年间，全省共对80.27万人进行了间日疟根治的氯喹和伯氨喹啉传播季节前治疗，对76.43万高危人群进行了传播季节预防服药，对43891例病人进行了治疗或疑似治疗。共检测发热病人1121.61万例，阳性11213例（阳性率0.10%），占全部疟疾病例的29.01%（11213/338654）。1990 - 1992年及1996 - 1999年共处理蚊帐133.28万顶，保护人群199.93万人。1990 - 2000年共检测包括学生在内的居民34846人，IFA T法阳性1149人（阳性率3.30%）。包括学生在内的当地居民71234人，带虫率0.40%（286/71234）。主要传播媒介为中华按蚊和嗜人按蚊。中华按蚊和嗜人按蚊叮人习性分别为0.0608和0.3143，嗜人按蚊媒介能量为中华按蚊的22.4倍。此期间全省共报告疟疾病例38654例，年发病率为2.62/10万，发病率最低年份为1992年（0.37/10万）。其中70.05%（27076/38654）的病例来自嗜人按蚊分布区。
河南省疟疾防治工作总体效果显著，疫情稳定，但部分地区仍不稳定，时有暴发点或局部流行发生。
