AlHijjah 30, 1435, Oct 24, 2014, SPA -- Doctors Without Borders insisted Friday, after one of its doctors who worked in Guinea came down with Ebola in New York City, that self-quarantines are not necessary when there are no symptoms of the disease, according to AP. Craig Spencer arrived back in New York about a week ago, reported a fever on Thursday and is now being treated at a New York hospital. Some countries have banned travelers from the three main Ebola countries" Guinea, Liberia and Sierra Leone and the U.S. started health screening of travelers arriving from there. In a statement sent to The Associated Press from Dakar, Senegal, Doctors Without Borders said that having its staffers quarantine themselves after leaving a country with Ebola is going too far if no symptoms are evident. A person infected with Ebola is not contagious until he or she starts showing symptoms. -- SPA 19:30 LOCAL TIME 16:30 GMT تغريد
