According to the tweet:
"Students and workers in all educational facilities (governmental and private) and those coming from travel will not be allowed to enter educational facilities before making sure that they are free of illness."
Officials gave no details how tests will be conducted, or the level of the testing. A simple temperature test, for example, has long been conducted at entry points to Singapore's schools for any student or visitor, while staff at Singapore's schools have temperature readings taken twice a day.
Earlier last week, the Ministry announced that all schools in the country would be closed for four weeks to boost efforts to contain the spread of the virus. A sterilisation programme for all educational facilities is being carried out in all schools, buses and universities over the next fortnight.
On Thursday 5th March, the Ministry of Health called on citizens and residents to avoid travelling due to the coronavirus.
It said in its statement revealed that if travel is a must, preventive measures will be taken upon their return to the country.
Measures taken will be in the form of medical checks at the airport and then home quarantine if the traveller is showing signs of illness. In case of actual infection with the virus, procedures will be applied for sanitary isolation in health facilities.
For students and school staff however, measures may be stricter.
A tweet from the Ministry of Education, sent late afternoon on Thursday 5th April, suggested a 14 day period of quarantine for students and school staff, no matter where they had been, to ensure they are healthy before they return to school.
