Are you unclear how researchers from abroad planning to come to the Czech Republic should proceed? Please find below at least basic instructions:
Effective from September 21st, 2020 all persons travelling from countries that are not on the list of the countries with a low risk of contagion have the obligation to contact the regional hygienic station according to the place of stay before their arrival. Electronic form is available here. This form has to be submitted also during the border control or the controls during the stay in the territory. More information on the Form is here.
Since Friday February 5th, 2021 there is a new category of so-called dark red (high-risk) countries with the strictest epidemiologic measures applicable to journeys from this category. This means that there is the obligation to submit a first PCR test done 72 hours or less prior to the departure, followed by a second PCR test undergone in the Czech Republic at the earliest the 5th day from the entry. The self-isolation is obligatory until the second negative test result is submitted.
In case of journeys from orange and red countries, there is the obligation to submit an antigen test done 24 hours or less prior to the departure or PCR test done 72 hours or less prior to the departure. In case of red countries, a person must likewise undergo a second PCR test in the Czech Republic (this can be undergone also earlier than the 5th day from the entry). The self-isolation is obligatory until the second negative test result is submitted.
