Malaria prophylaxis is the preventive treatment of malaria. Several malaria vaccines are under development. ==Strategies== * Risk management * Bite prevention—clothes that cover as much skin as possible, insect repellent, insecticide-impregnated bed nets and indoor residual spraying * Chemoprophylaxis * Rapid diagnosis and treatment Recent improvements in malaria prevention strategies have further enhanced its effectiveness in combating areas highly infected with the malaria parasite. Additional bite prevention measures include mosquito and insect repellents that can be directly applied to skin. This form of mosquito repellent is slowly replacing indoor residual spraying, which is considered to have high levels of toxicity by WHO (World Health Organization). Further additions to preventive care are sanctions on blood transfusions. Once the malaria parasite enters the erythorocytic stage, it can adversely affect blood cells, making it possible to contract the parasite through infected blood. Chloroquine may be used where the parasite is still sensitive.〔 However, due to resistance one of three medications: mefloquine (''Lariam''), doxycycline (available generically), and the combination of atovaquone and proguanil hydrochloride (''Malarone'') is frequently needed.〔 Doxycycline and the atovaquone and proguanil combination are the best tolerated with mefloquine associated with higher rates of neurological and psychiatric symptoms. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Malaria prophylaxis」の詳細全文を読む スポンサード リンク
