Overview: Arrivals from countries designated as high-risk travellers – nationals of China, Korea, Iran and Italy, in addition to Macau and Hong Kong – must have a medical certificate confirming they are not infected with COVID-19.
If not, air operators are to refrain from issuing a boarding pass.
Where nationals of the four countries satisfy this first requirement, they may travel. A mandatory quarantine period upon arrival is expected thereafter.
