as part of the EU-funded project “Healthy Sailing”


What is this project about, and do I have to take part?

This study aims to inform cruise ship company infection prevention, preparedness and outbreak response measures, including policies, interventions and communications. The information collected through this survey is important to support the implementation of specific interventions before, during and after the cruise. Participation is open to people aged 18 or over, taking part in this cruise voyage and is entirely voluntary.

What are the benefits and risks of taking part?

You may benefit from taking part in the survey by being motivated to look up information about the respective infectious disease prevention measures. We will provide you with reliable and trusted resources at the end of the study. There are no foreseeable risks for you when taking part in the survey, other than time spent on the survey and potential discomfort. Should you feel uncomfortable and want to leave the study, you are free to do so without any consequences.

What will you ask and what will happen to the information I give you?

You will be asked questions about yourself, your knowledge and attitudes about infectious diseases that may occur before, during or after cruise travel, and actions you would likely take to protect yourself and prevent infection spread. As a rule, we will attempt to exclusively collect anonymous data about you. However, due to current and future technological developments, it might be possible for some of your data to be identifiable in the future. For that reason, we will treat all the data included in your survey responses as pseudonymized personal data. You may find detailed information about the processing of your personal data below (chapter “personal data protection information”).

Your data will be collected by the University of Thessaly and analyzed by the Laboratory of Hygiene and Epidemiology, Faculty of Medicine.  As a result of the scientific analysis, completely anonymous study results and aggregated data will be produced. The anonymous study results and statistics will be shared with relevant researchers and government agencies to assist in the development of infection prevention, preparedness, and outbreak response measures on ships.

Personal Data Protection Information

As mentioned before, the study surveys will be collected anonymously. We have taken measures to ensure that the collected data is minimized, and we do not need to identify you personally to achieve the study results. However, due to current and future technological developments, it might be possible for some of your data to be identifiable in the future. For this reason, we take measures to treat all the information which you will provide us through the survey as personal data and protect them accordingly.

This section will provide you with information regarding the processing of your personal data in the context of your participation to this study.
