Via the Ottawa Citizen: Public health officials search for 200 families exposed to measles virus. Excerpt:
Ottawa Public Health officials are trying to track down 200 families that may have been exposed to a child with measles over four days in late February.
The unidentified child, a student at St. Stephen School in Stittsville, has been released from hospital and is out of medical danger, but others who may have been exposed to the highly contagious disease remain at risk.
Among those at risk are St. Stephen students who have not been immunized.
Ottawa Public Health officials have identified a dozen St. Stephen students who have not submitted the required immunization records. Those students were issued school suspension letters Thursday by the city’s public health agency, which has the power to suspend students without up-to-date immunization records for 20 days.
“If they come forward with immunization records then they will be removed from that suspension list,” said Dr. Rosamund Lewis, Ottawa’s associate medical officer of health.
Infants and adults who have not been immunized are at greatest risk of developing a severe case of measles.
Those exposed may not know they’re infected since the incubation period for measles is about 10 days, according to the Public Health Agency of Canada. The rash commonly associated with the disease usually appears two weeks after exposure.
Ottawa Public Health has not yet found any sign that the virus has spread to new patients.
The city’s public health officials have identified three potential exposure points in addition to St. Stephen School: the Med-Team Clinic on Kakulu Road in Kanata (between 8:45 a.m. and noon on Feb. 25); the Active Care Clinic on Klondike Road in Kanata (between 9:30 a.m. and 1 p.m. on Feb. 27); and CHEO’s emergency department (between noon and 2:20 p.m. on Feb. 28).
The infected child was not diagnosed with measles until a third medical visit.
