COVID-19 measures


As you will certainly understand, CERN cannot predict the spread of the virus or the evolution of event or travel restrictions, airline polices or flight/public transport cancellations. Your participation in the School is at your own risk and, in particular, CERN, University of Split and MEDILS are not responsible for any costs associated with early departure from or termination of the School, travel, quarantine, medical treatment or any other consequences resulting from being infected or a close contact during or in connection with participation in the School. Please ensure you have the necessary travel and medical insurance in place to cover your attendance.


This is a detailed COVID-19 prevention plan for the School, based on MEDILS instructions and current Croatian rules, and taking into account specific requirements of the School.

It’s important to note that the national or local rules might change as the situation evolves; in which case the following School sanitary measures will be adapted accordingly.


It is participants' individual responsibility to ensure that they fulfil all the requirements to travel to Croatia. Depending on the country of residence, participants may need to present a valid EU Digital COVID-19 Certificate, or equivalent - more details are available at https://entercroatia.mup.hr/


MEDILS institute requires all school participants to provide a negative result of a PCR test (not older than 72 hours) or rapid antigen test (not older than 48 hours) by email to Mrs. Irena Rajic (irena.rajic@medils.hr), who is MEDILS coordinator responsible for COVID measures. We recommend to take the test before the travel to Croatia. 

Participants with COVID-19 symptoms (including fever, cough or respiratory problems) are asked not to travel to Split, and will not be allowed to enter MEDILS and to attend the School.

COVID-19 self-testing

COVID-19 self tests will be available on a voluntary basis to all participants. The goal is to reassure participants and personnel, as well as to identify any infected persons as quickly as possible.

In specific cases, taking a COVID-19 test and presenting a negative result may be required by the School organiser, by the hosting institute or by the local authorities.

Sanitary measures

During the School, we will all be required to follow standard COVID-19 sanitary measures that are in line with national and local regulations.

For the safety of all participants and personnel at the School, an individual participant’s failure to comply with the required sanitary measures will result in their expulsion from the site.

  • Physical distancing: The big conference room used for all classes will be prepared to seat School participants while respecting the recommended distance of at least 1.5m between them. Similarly, the outdoor space where meals are taken will be arranged to limit the number of people per table, and increase the distance between them. Finally, the participants will be encouraged to limit close contacts especially if indoors and/or during prolonged periods.
  • Masks: Wearing surgical masks (type 1, 2 or 2-R / EN 14683) will be required in the following situations:
    • while queueing for the buffet meals at MEDILS, and getting the food/drinks;
    • when discussing directly with the lecturers or other participants during the hands-on exercise sessions;
    • in buses, taxis or other shared transport.
  • In additional to these rules, the School organizers encourage wearing masks in all situations (other than meals) when participants interact in close proximity (less that 1.5 m), especially if indoors and/or during prolonged periods. Surgical masks will be made available at MEDILS.
  • Hand hygiene (washing and disinfection): Hand sanitizers are available at various locations in MEDILS. Disinfecting hands will be mandatory before taking food at the buffet-style meals, and in other occasions which require touching or handling share items. Finally, participants are strongly encouraged to wash their hands regularly.

Additional measures will be implemented by the School organisers:

  • Ventilation of the common spaces:
    • The big conference room used for all classes has windows on both sides, which will be kept open during the classes to allow constant ventilation with fresh outside air.
    • The meals at MEDILS take place in the outdoor space. This space will also be used for social activities and gatherings.
  • Disinfection and housekeeping: Common spaces in MEDILS and in the hotel, and in particular the elements that are often touched (such as door handles, lift buttons etc.) will be regularly disinfected. Similarly, rooms where School participants are accommodated are cleaned regularly.

Quarantine / medical isolation

We cannot exclude the possibility that, even with all the above measures in place, one, a group, or all participants and personnel attending the School may be required to quarantine or isolate, even if they are vaccinated.

If allowed by the local epidemiological authorities, the affected person(s) can quarantine directly at the School accommodation (but only for the duration of the School – i.e. until Saturday June 25th morning). In that case, the cost of the accommodation and food for quarantining during the School is already covered by the participant’s registration fee.

However, any other costs of self-isolation or quarantine outside of the School accommodation, and/or after the end of the School, will be under the sole logistical and financial responsibility of the individual participant(s) concerned, and cannot be covered or arranged by the School organizers or MEDILS.
