BUDAPEST, Hungary — The Hungarian government said Sunday that it will reimpose restrictions, such as mandatory two-week quarantines or bans, on people arriving from countries where the rate of coronavirus infections is considered to be moderate or high.

“We see worrisome signs about an increase in the number of cases in the neighboring countries, Europe and the whole world,” said Gergely Gulyas, Prime Minister Viktor Orban’s chief of staff.

Gulyas said only Hungarian citizens will be allowed to enter from countries in the “red” category — those with a high rate of infections — including Albania, Ukraine, Belarus and practically all of Asia, Africa and South and Central America. They will have to stay in quarantine for two weeks, but will be allowed out earlier if they get two negative test results 48 hours apart.

Both Hungarians and foreigners arriving from countries in the “yellow” category — which includes, among others, Bulgaria, Portugal, Romania and Sweden, as well as Britain, Russia, Serbia, Japan, China and the United States — will have to quarantine for two weeks, but will be allowed out if they test negative for the virus: once in the case of Hungarians, or two negative tests 48 hours apart in the case of foreigners.

Gulyas said the new measures, which will take effect Wednesday, will be reviewed at least once a week

Hungary registered five new coronavirus cases in the past 24 hours, with no new deaths linked to the pandemic. In total, Hungary has registered 4,234 cases, including 595 deaths.
