Rules and recommendations
Do you plan to travel abroad and do not know what conditions associated with measures against COVID-19 apply to you and what are your obligations after returning to the Czech Republic? Take a look at the website of the Ministry of Foreign Affairs in the so-called Traveler Map.
There you can find the country you plan to visit and see if you need to take a test before leaving, or go to the mandatory quarantine, etc. on this map. This map also contains information on the obligations arising from returning from that country. Those can include, for example, the obligation to take the COVID-19 test and have negative results, a completed arrival form, etc.
The Ministry of Foreign Affairs of the Czech Republic recommends that you secure travel insurance before your trip, including medical expenses in the event of COVID-19.
Example from the Traveler's Map Austria: As of October 31st, 2020, Austria has included the Czech Republic among the risk areas in terms of the occurrence of COVID-19. This means that from October 31st, 2020, persons arriving from the Czech Republic are obliged to submit a medically confirmed COVID-19 negative test (negative PCR test) upon entering Austria, which must not be older than 72 hours. If travelers do not have it, they must isolate themselves in suitable accommodation (at their own expense) and request a COVID-19 test within 48 hours. In case of a negative test result, the quarantine will be terminated. Exceptions are made for commuters, commuting students, or regular family visits.
