According to Acting School Administrator, Mark Phillips in a letter to Staff and Parents Friday, We have just received news that another Class 10 student is confirmed to have measles. We are informed that she caught it in the first week of the Term when she was at school with the original student.

Perth Waldorf School sent home 19 unvaccinated students.

Phillips  said the student has been kept in “tight quarantine” at home and her sibling has also been kept from attending school until she can no longer be infectious.

Last week, WA Health reported a case in an unvaccinated child who contracted measles while traveling in Europe.
