The map shows the distribution of Plasmodium falciparun (Pf) malaria in China at the province level. Pf is one form of plasmodium infection which often presents with a feverish disease, the severe form of which can be fatal. The average number of reported Pf cases for the year 2004/2005 is presented in the map. Evidently the total number of known cases of malaria is very low across the country. The disease is largely limited to Yunnan and Hainan Provinces, which contain the most seriously affected areas. In other parts of the country, including Hong Kong, isolated cases of malaria are reported, which are normally imported. Data for the map were obtained from CDC China.

地圖顯示2004-05年惡性瘧在中國各省的年均病例數。惡性瘧是其中一種瘧原蟲引起的熱病,嚴重可以致命。全國瘧疾報告數很低,而雲南和海南省為惡性瘧本地流行的两個省份。香港和其它省份一樣,偶然發生瘧疾個案,但一般因外游感染。地圖數據源自中國疾病預防及控制中心。

Malaria 瘧疾

Malaria is caused by a parasite called plasmodium, which is transmitted via the bites of infected anopheles mosquitoes. Plasmodium is a single-celled protozoan parasite with a larger size than bacteria. It is widespread in tropical and subtropical regions. Each year, there are approximately 350-500 million cases of malaria, killing between one and three million people worldwide. Four types of the plasmodium parasite can infect humans; the most serious forms of the disease are caused by Plasmodium falciparum (Pf). The main means of malaria control include the use of insecticidal nets, treatment intervention, and mosquito control.

瘧疾是由瘧原蟲引起,通過蚊蟲叮咬傳播的寄生蟲病。瘧原蟲是單細胞寄生蟲,體積比一般細菌為大。瘧疾廣泛分布于熱帶和亞熱帶地區。每年全球大約有3.5-5億人感染瘧疾,有100-300萬人死于該病。四種瘧疾原蟲可以導致人類瘧疾,其中最嚴重的是惡性瘧。控制瘧疾的主要方法有:使用驅蚊帳、藥物治療和控制蚊蟲滋生。
