Introduction According to World Health Organization (WHO), approximately 40% of the world's population, mostly those living in the world's poorest countries, is at risk of malaria. The disease was once more widespread but it was successfully eliminated from many countries with temperate climates during the mid 20th century. Today malaria is found throughout the tropical and sub-tropical regions of the world and causes more than 300 million acute illnesses and at least one million deaths annually, including Latin America. This is in part due to the development of unacceptable levels of resistance to one drug after another in the malaria parasites, especially Plasmodium falciparum. Additionally, many insecticides are no longer useful against mosquitoes transmitting the disease. All this represents a public health threat, even in those areas where malaria is not endemic, or where P. falciparum is not present; due to migration, travels and other people mobilizations, which could spread resistant strains. * This case was previously presented in part at the 19th Sucre Malariology Meeting, Sucre, Venezuela, May 2003..
