Prävention und Management von COVID-19-Ausbrüchen auf Handelsschiffen: Technische, organisatorische und persönliche Schutzmaßnahmen zur Risikominimierung in einem besonderen Arbeitsumfeld

BACKGROUND: A pandemic is a particular medical challenge for seafarers traveling without a physician on board. At the same time the global fight against the coronavirus disease 2019 (COVID-19) pandemic has to rely on resilient merchant shipping in order to maintain the flow of goods. For infection prevention and management on board, those responsible need a portfolio of protective measures that can be used on ships. RESEARCH QUESTIONS: The overview examines the question of which technical, organizational and personal protective measures can be used on a merchant ship in order to prevent or cope with COVID-19 outbreaks on board. MATERIAL AND METHODS: Guidelines, information and occupational health and safety standards from the maritime setting, but also from many other work areas, were examined in order to facilitate a variable use by those responsible (e.g. according to ship size, equipment, weather, operating status, work requirements, contact with external persons, medical problems). RESULTS: A handout was compiled that contains specific technical, organizational and personal protective measures for crews, explaining their use in a maritime context. Possible safety barriers, options to combine them and an appropriate timing are explained in a target group-oriented manner. CONCLUSION: A great variety of protective measures derived from occupational medical literature and the experience of the port medical service in Hamburg can also be implemented on the high seas. In pandemic times, merchant ships should be equipped with foresight (e.g. with rapid diagnostic tests) and those responsible should be authorized to use effective infection control measures adapted to the situation on board. Seafarers should receive priority vaccination offers regardless of their national origin.
