The Nova Scotia Health Authority's public health division is warning anyone who visited Halifax Infirmary's emergency department on April 17 that they may have been exposed to measles. On Saturday, officials in Nova Scotia confirmed that same person was travelling through Halifax. On April 17, they visited the emergency department on Robie Street for symptoms unrelated to measles. Patients and visitors to the Halifax Infirmary emergency department on April 17 from 12 a.m. to 12:30 p.m. may have been exposed and may develop symptoms between now and May 8. People in Nova Scotia born after 1970 are eligible to receive two free doses of the measles vaccine through the province's immunization program.
