There's been a recent jump in U.S. malaria cases.

FOX News Radio's Paul Stevens has details:

U.S. malaria cases at their highest point in four years. That jump thanks mainly to Americans bringing the disease home after foreign travel. Malaria still not a big problem in the U.S. with just over 1,900 cases in 2011 and five deaths. But that case total jumping 14% from 2010 with the biggest total since 1971. 60% of infections taking place in Africa. Malaria spreads through infected mosquitoes.
