Connecticut has placed six West Africans who recently arrived in the United States under quarantine for possible Ebola exposure, a move that comes as the U.S. imposes new restrictions on those coming from countries hardest hit by the virus. The family of West Africans, who are planning to live in the U.S., will be watched for 21 days. State officials have not yet said where exactly the family came from. The Obama administration has been under pressure to halt travel to the U.S. by people from Liberia, Guinea and Sierra Leone, but has opted for tougher controls instead. A New York doctor who treated Ebola patients in West Africa has been diagnosed with the disease.
