Leading figures in the fight against Covid-19 have warned that the UAE could face a "second wave" of coronavirus cases.
In a television interview on Sunday, Obaid Al Shamsi, director general of the National Emergency Crisis and Disaster Management Authority, spoke of an urgent need for people to be vigilant to avoid a second wave of Covid-19 cases.
"We need to be aware that the UAE strategy is a balance between the health sector and the economy," he said.
"People think that by opening the economy, the pandemic is over. It is not over. And if we neglect it, then we will face a second wave."
The Ministry of Education this week that schools would temporarily close if two or more cases were identified.
The authority announced new guidelines for the safe return of staff and pupils to classrooms from Sunday.
Using a calculation based on the number of new cases in the community to determine the threat to schools, the guidelines set out four levels of risk: low, moderate, high and extreme levels.
In the event of an 'extreme risk' to safety, which is is reached when there are at least 36 cases per 100,000 population in seven days, in-class lessons will be halted, with a return to full-time distance learning.
