Hungary will close its borders to non-residents from Tuesday to try and curb the increasing number of coronavirus cases, the government said on Friday.
The move comes as several European countries implement stricter COVID-19 measures.
"From September 1, foreign citizens will no longer be allowed to enter the territory of Hungary," Gergely Gulyás, the prime minister Viktor Orbán’s cabinet chief said during a press briefing.
"There is a risk of introducing the virus and most of the new infections are of foreign origin," he said, adding "Hungary is green, all other countries are now turning red," in reference to the traffic light system.
He said Hungarian citizens returning from abroad must quarantine for 14 days or must present two negative tests, which they must pay for themselves.
Hungary's government indicated that the border closure will stay in place for a month.
The country, which has a population of around 10 million, has around 5,500 COVID-19 cases. More than 600 people have died in Hungary due to the virus.
The move comes amid an uptick in coronavirus cases and as countries implement new precautions.
