Malaysia was moved to this list as it was expanding the scope of its entry ban from parts of Korea to the entire country, effective from Friday. Guatemala, Montenegro in the Balkans and Moldova in Eastern Europe also joined the list, with some exceptions applied to foreigners with residential permits.

Serbia now bars the entry of travelers from Korea's Daegu city and North Gyeongsang Province -- two epicenters of the COVID-19 outbreaks -- putting the number of countries and territories imposing such restrictions at six.

Eighteen countries and territories, including 21 Chinese provinces, were enforcing stricter quarantine programs on people from Korea and other virus-affected nations.

The number of countries and territories imposing stricter immigration controls and requiring or recommending isolation for travelers from Korea came to 52, joined by the Czech Republic and Niger in West Africa.

The Czech Republic requires visitors from Korea to report their arrival to health authorities and strongly recommends a 14-day self-quarantine.
