Totally 64 178 malaria cases and 52 082 suspected cases with 38 deaths were reported by the annual case reporting system in 917 counties of 23 Provinces/Municipality/Autonomous Regions （P/M/A） in 2006, and the annual incidence was 0.50/10 000. Through the internet reporting system 60 382 malaria cases were reported from 1 097 counties of 30 P/M/A. The number of malaria cases and the rank of P/M/A were basically in concordance in the two systems.
Among the 917 counties with reported malaria cases, 29 counties with an incidence more than 10/10 000 distributed in Yunnan （15 counties）, Hainan （6）, Anhui （7）, Henan （1）. There were 76 counties in which the malaria incidence was between 1/10 000 and 10/10 000.
3 469 Plasmodium falciparum malaria cases accounted for 5.4% of the total cases, of which 60.4% （2 097） were imported cases in 206 counties/cities of 17 P/M/A. Indigenous falciparum malaria was found in 38 counties/cities of Yunnan and Hainan Provinces, of which 26 counties/cities were in Yunnan, and 12 counties/cities were in Hainan, decreased by 5 and 4 respectively in comparison to that of 2005.
Focal outbreaks occurred in 183 villages of 16 counties in Yunnan, Anhui, Henan and Guizhou Provinces. 3 058 malaria cases from the outbreaks accounted for 4.8% of the total reported cases.
Although a considerable decrease in malaria incidence was contributed to the implementation of the Global Fund Programme, Yunnan and Hainan Provinces were still relatively high transmission areas. Yunnan ranked No.2 in the country in terms of the number of cases, while Hainan ranked down to No.2 by malaria incidence for the first time after ranking No.1 for years. 19 385 malaria cases were reported from the two provinces in 2006, accounting for 30.2% of the total reported cases in the country. There were 15 532 cases with 32 deaths reported from Yunnan, the incidence was 3.89/ 10000, a decrease of 21.4% than that in the last year. Among the reported cases, 3 090 were falciparum malaria with 60.4% imported
