Closing schools for 2 weeks does not happen every year as a result of Flu. Even the bird flu each year at this time for the last 4 years has not shut school doors as a result.
Normal schools ie govt schools only close next thursday which means schools have closed a week ahead of the easter holidays and not 2 days. Perhaps other ESF/INTL schools have differrent holidays but the masses are at Govt schools.
Secondary schools may close from monday which is still ahead of the holidays with temperature monitoring at all schools compulsory as of today.
