Ebola outbreak: US will not enforce quarantine US health officials will actively monitor colleagues who have treated Ebola patients in West Africa, under new rules. Updated guidelines issued yesterday will require most medics to be checked for symptoms for 21 days but will not require quarantine or isolation. The announcement comes after a nurse who complained about her quarantine in New Jersey was allowed to return home. Defying the new guidelines, New Jersey Governor Chris Christie defended the mandatory isolation. His stance conflicts with UN Secretary General Ban Ki-moon, who earlier said those seeking to help in affected areas, should not be subjected to restrictions that are not based on science. BBC
