The Dubai government did not impose any travel restrictions for any passengers arriving in Dubai including tourists and returning OFWs from the Philippines.
As of this writing, anyone from other countries are allowed to enter and leave Dubai legally.
However, mandatory thermal screening and medical swab will be done in Dubai airports to monitor passengers with coronavirus. Only those with symptoms off the disease will be sent to the hospital for treatment and possible quarantine.
It is not also true that Dubai is imposing mandatory quarantine for all people who enter the emirate. Only those people showing symptoms are required to see medical practitioners and go for quarantine.
Debunking a notorious fake news on flights from Dubai to the Philippines, Dubai did not cancel flights coming to and from the Philippines or other countries.
