About one-fourth of US Peace Corps volunteers serving in malaria-endemic regions of Africa don’t take the prescribed antimalarial medications that the agency requires, according to a recent survey.
In addition to insecticide-treated bed nets and mosquito repellents, preventive medications are recommended for long-term travelers to regions where malaria is endemic. The 3 that are available in Africa are mefloquine, doxycycline, and atovaquone-proguanil.
Concerns about increasing cases of severe malaria among Peace Corps volunteers prompted the survey. Since 1961, 7 volunteers have died of malaria contracted during their service. From 2009 to 2012, however, malaria case rates among volunteers went as high as 18 cases per 100 volunteer-years.
