SCHOOLS have been contacting students who travelled to flu-affected countries during the June break to remind them not to attend holiday classes and activities within a week of returning home.

At least one, Ping Yi Secondary School, has even cancelled non-essential activities, such as camps. It will also have its security guard check at the school entrance if students have been to any of the listed countries.

A check with 17 primary and secondary schools and junior colleges found them busy telephoning, e-mailing or sending text messages to staff and students who have been to countries with sustained community transmissions, such as Thailand, Canada and the United States.
