The most recent cases were travel related, returning from the Philippines in early April, said AHSmedical officer of healthDr. Judy MacDonald. Theyre linked to one another that way.

Brenda Land, president of the Henry Wise Wood High Schoolparent council, said her 16-year-old son Eaon found out Monday morning in biology class.

"Very surprisingly he texted me today to let me know that the school had a confirmed case of the measles outbreak and that students were being asked to go home if they'd not been immunized or had the measles. And apparently this is affecting some of the teachers as well."

At Henry Wise Wood High School, 80 students and staff have been told to stay home because they have not been immunized or their records can't be found.

At Sherwood School in southeast Calgary, whichhasstudents from grades 5 to 9, about 30 students and staff have been told to stay home. Theymay have been exposed on April 7.

Some students told to stay home

Public health and school authorities postednotices about measles on both schools' websites Monday.

Letters from the schools' principals says somestudents will need to remain at home from April 12 to April29 to prevent spreading the disease.

"Wewill be providing the instructional support that students need during, and after, the exclusion period to maintaintheir studies," one letter states.

Parents who had their children immunized in other jurisdictions can bring immunization records to public health officials, saidMacDonald.

If they make that decision [not to vaccinate], they also need to know they have responsibilities. And one of those is when their child is exposed to measles and they are not immunized, their child will be excluded from school.

Twice this year,Alberta Health Services has also warned of possible measles exposure atWestern Canada High School.
