The Center for Disease Control of the United States has discontinued their recommendation to take antimalarial drugs to travelers to the La Altagracia province, including the resorts at Punta Cana and Bavaro. The outbreak notice is lifted after no new malaria cases in travelers have been reported from the area since January, after 20 cases were reorted from 3 November 2004 to 10 January 2005.
