WASHINGTON - The United States announced Thursday it will end enhanced screening of passengers for potential Ebola virus infection from West Africa after an epidemic that killed more than 11,000 people. On Friday, Guinea will be removed ‘from the list of nations affected by Ebola for which travelers are subject to enhanced US visa and port-of-entry screening,’ said the US Centers for Disease Control and Prevention. ‘Guinea will be the last of the affected countries in West Africa to be removed from enhanced entry screening measures.’
