The U.S. Department of State has issued a travel warning to U.S. citizens regarding travel to Nigeria.
“The Embassy is not able to offer medical treatment to travelers; however, it can provide a list of medical facilities that may be able to treat U.S. citizens with medical emergencies. In July 2014, the U.S. Embassy in Abuja reported confirmed cases of Ebola Virus Disease (EVD) in Nigeria. Since that time, new reports of deaths and confirmed and suspected cases of persons with EVD or Ebola-like symptoms have been reported. For further information on the Ebola virus, U.S. citizens should consult the Centers for Disease Control (CDC) and Prevention website and also visit the U.S. Embassy website to review Security Messages addressing the Ebola virus in Nigeria. On August 5, the CDC issued a Travel Notice advising enhanced health and hygiene precautions for travelers to Nigeria due to the Ebola virus. On July 31, the CDC issued Travel Notices warning against nonessential travel to Guinea, Liberia, and Sierra Leone due to the Ebola virus.”
