"Let's postpone these trips if we can," Rolanda Lingiene, the director of the National Public Health Center's Vilnius Department, told reporters, noting that it would take "a miracle" to prevent the quarantine requirement for returnees from Poland to be imposed as of Monday.

"Not only from Poland; there are several more candidates (for blacklisting)," she added.

Two-week quarantine is mandatory for travelers returning from countries with 16 new COVID-19 cases per 100,000 people over the last two weeks.

Poland is currently not on the "blacklist" that is updated by Lithuanian Health Minister Aurelijus Veryga every Friday.

The neighboring country has reported 640 new coronavirus cases and another 18 deaths over the past 24 hours.

This brings its total coronavirus infection count to 48,789 and its total death toll to 1,756.

Poland had 17.9 cases per 100,000 as of Monday, according to the European Center for Disease Prevention and Control.
