From March 28, 2022, pursuant to the provisions of the Regulation of the Council of Ministers, all pandemic restrictions regarding travel to Poland are lifted, which means that there is no longer any obligation to present vaccination certificates when crossing the border, make SARS-CoV-2 tests or undergo entry quarantine. Link to the regulation in question (Polish version only):  https://dziennikustaw.gov.pl/DU/2022/679

Lifting of the obligation to wear facemasks
From March 28, 2022, covering the mouth and nose is not obligatory, but we still recommend using facemasks.  
Exception
It is still mandatory to wear a mask in pharmacies, hospitals and other health care facilities.

Airplanes
The rules for wearing masks on board airplanes will be regulated independently of the regulation by the airlines. Due to the changing sanitary conditions and regulations, both at home and abroad, we advise you to verify the currently applicable restrictions before each flight (on the day of departure).

Conference venue
We recommend not to participate in the conference if:
  • you  have been within the last 7 days infected with SARS-COV-2 coronavirus or suspects such infection;
  • you are in quarantine or under epidemiological surveillance.
  • during the conference you have symptoms of infection that may indicate the likelihood of infection with SARS-COV-2 virus (elevated temperature, flu-like symptoms, e.g. fever, sore throat, headache, runny nose, cough, shortness of breath and breathing problems, etc.).
We recommend you:
  • wear a mask to protect the mouth and nose at all times while in the conference venue, except when giving presentations and eating meals.
  • to keep a distance between participants.
  • to use hand sanitizer each time they enter the congress/event venue.

Departure
If you  have  to make a test before departure for your country, you can do it  at the airport. We recommend to register for a test  on-line. Registration speeds up the entire process and reduces the waiting time.
