The State Department has issued a revised Haiti travel advisory, warning Americans planning to travel to the Caribbean island nation about robbery, lawlessness, infectious disease and poor medical facilities, The Associated Press reported. "U.S. citizens have been victims of violent crime, including murder and kidnapping, predominantly in the Port-au-Prince area. No one is safe from kidnapping, regardless of occupation, nationality, race, gender, or age," the department said. The new travel warning was released Friday to replace a less strongly worded advisory issued in June. In recent months, travelers arriving in Port-au-Prince, the capital and largest city, on flights from the United States have been attacked and robbed after leaving the airport. This year, at least two U.S. citizens were shot and killed in robbery and kidnapping incidents, the State Department said. The State Department also noted that while the incidents of cholera have declined, the disease persists in many areas of Haiti. Medical facilities, including ambulance services, are particularly weak.
