Malaria ( 瘧疾 ) Group 8 Pinky Yu, Venky Chow, Jasmine Chong, Shadow Cheung

Causes and Spread  Protozoan( 原生動物的 ) parasites of the genus Plasmodium( 瘧原蟲 )  Spread by some kinds of mosquito  Also infect birds, reptiles, monkeys, chimpanzees etc.  Most serious place : Africa A Plasmodium sporozoite

Symptoms  Fever  Shivering ( 發抖 )  arthralgia ( 關節痛 )  vomiting ( 嘔吐 )  anemia ( 貧血 )  hemoglobinuria ( 血紅素尿 )  retinal damage ( 視網膜受損 )  convulsions ( 抽筋 )

Treatment  Antimalarial drugs ( 抗瘧藥 ) Chloroquine  Cheap and effective  But resistance of Malaria to it spread recently  Ineffective against the most dangerous Plasmodium strain in many affected regions

Prevention  Vector ( 帶菌者 ) control The use of the pesticide DDT  Prophylactic ( 預防 ) drugs e.g. Quinine  Indoor residual spraying Spraying insecticides on the interior walls of homes in malaria affected areas  Mosquito nets and bedclothes Keep mosquitoes away from people
