Consult the “Mexico and Central America” page of the U.S. Centers for Disease Control (CDC) website for up-to-date health recommendations and advice (www.cdc.gov ) or call their International Travelers Hotline (U.S. tel. 404/332-4559 or 877/394-8747). You can also contact the Nicaraguan embassy in your country.
