Notification of infectious diseases

If a vessel is on an international voyage and intends to enter a port, it is important that it is clear whether there is a patient with an infectious disease on board. When the master of the vessel suspects that there are one or more patients on board with an infectious disease, he must report this to the Harbour Coordination Centre (tel. +31 (0)10 252 1000) as well as the pilot as soon as possible. This is in accordance with the Public Health Act. The Harbour Coordination Centre will coordinate the steps to take.

In case the answer to any of these questions was 'yes', the master must inform the agent, pilot and the Harbour Coordination Centre. The master should mail the Maritime Declaration of Health to or fax it to number +31 (0)10 252 1600.

The completed form must be kept on board and at all times be available for presentation. The person responsible for medical care on board the vessel must be available to answer any additional questions.

Employees in the port of Rotterdam

In case a pilot, agent, employee of the customs, port police, military police or patrol vessels of the Harbour Master or any other employee in the port of Rotterdam, perceives signs that a patient with an infectious disease is on board of a vessel, he/she should ask the vessel to contact the Harbour Coordination Centre. In addition, the above-mentioned employees can also discuss signals regarding infectious diseases themselves with the HCC. The HCC will forward the question to the right partners within the Port Health Authority.

Physicians working in the port of Rotterdam

In addition to the general practitioners working in the port of Rotterdam, there are also many physicians working as company doctors for specific companies. These physicians are requested to notify the Harbour Coordination Centre in case of a suspected notifiable infectious disease. Moreover, according to the Dutch Public Health Act, these physicians are obliged to contact the Municipal Public Health Services Rotterdam-Rijnmond in case of a notifiable infectious disease.
