History of malaria fever with quinine, the effects of both syphilis and malaria could be minimized. While about 15% of patients died from malaria, this was preferable to the almost-certain death from syphilis. Therapeutic malaria opened up a wide field of chemotherapeutic research and was practised until 1950. Wagner-Jauregg was awarded the 1927 Nobel Prize in Physiology or Medicine for his discovery of the therapeutic value of malaria inoculation in the treatment of dementia paralytica. Henry Heimlich advocated malariotherapy as a treatment for AIDS, and some studies of malariotherapy for HIV infection have been performed in China. The United States Centers for Disease
Malaria in pregnant women and infants, and in preschool children where transmission is seasonal. There are a number of medications that can help prevent or interrupt malaria in travelers to places where infection is common. Many of these medications are also used in treatment. In places where "Plasmodium" is resistant to one or more medications, three medications—mefloquine, doxycycline , or the combination of atovaquone/proguanil ("Malarone")—are frequently used for prevention. Doxycycline and the atovaquone/proguanil are better tolerated while mefloquine is taken once a week. Areas of the world with chloroquine sensitive malaria are uncommon. The protective effect does not begin immediately, and
