The Education Bureau has announced in April that all schools in Hong Kong would gradually resume their classes in phases and orderly manner, with half-day classes in principle. Students must complete a rapid antigen test before returning to school each day, and can only return to school with a negative result. Schools are also required to collect student data every day and report it to the Centre for Health Protection. Parents are requested to assist their children to complete the quick check and fill in the ” Health Declaration Form” before returning to school every day. If the test result is positive, students are not allowed to return to school, and please notify the school as soon as possible and stay home. Parents of the students are also required to report to the Department of Health through the “Declaration System for individuals tested positive for COVID-19 using Rapid Antigen Test” (http://www.chp.gov.hk/ratp) within 24 hours.
