Croatia has found itself on the Dutch orange list of countries since Tuesday due to an increase in Covid-19 cases, and Dutch citizens are "strongly recommended" to have a 14-day self-isolation upon their return to the country, the authorities there announced.

"Travel warnings for Bulgaria, Romania, Sweden and Croatia will remain orange for a while. This is due to the epidemiological situation in those countries. If you still decide to travel there, it is strongly recommended that you go into 14-day self-isolation immediately upon returning to the Netherlands," reads the website of the Dutch government.

"Currently, the coronavirus infection rate in Croatia has increased. Therefore, the country from yellow has been placed on the orange list of countries," the government said.
The Dutch government also warns citizens that the situation with any country can change abruptly and that they keep this in mind when making travel plans.
