Abstract

Since 1963, reported malaria transmission in Haiti has been restricted to Plasmodium falciparum. However, screening of Haitian refugees in Jamaica in 2004, by microscopic examination, identified P. falciparum, P. vivax, and P. malariae. PCR confirmed the P. malariae and P. falciparum but not P. vivax infections. DNA sequencing and rRNA gene sequences showed transmission of P. malariae. This report confirms that P. malariae is still being transmitted in Haiti.

Highlights

  • Malaria remains an important disease in Latin America and the Caribbean, where 30.4% (264 million) of the 869 million persons live in areas where ecologic conditions have been propitious for the transmission of malaria [1]

  • Our results provide conclusive evidence that P. malariae is still being transmitted on the island of Hispaniola, which contains the countries of Haiti and the Dominican Republic

  • P. malariae and P. brasilianum have been reported in both human and simian hosts in the continental South American states of Suriname, French Guiana, and Brazil [8,12,13], which are located on the northeastern coast of the continent, facing Hispaniola
