Around 11:20 a.m., police shut the Mass. Ave. Orange Line stop, stopped train service and blocked traffic on Mass. Ave. after somebody started vomiting on the platform.
The station and street were re-opened about 15 minutes later - and the person transported to a local hospital - after first responders determined she did not have Ebola.
Boston EMS Incidents reports EMTs rushed to the station on a report of "an external hemorrhage."
Boston Magazine has more: The situation started when somebody called 911 to report "a Liberian woman" with Ebola. In fact, she was a Haitian woman.
