Ships cross borders every day, connecting countries and serving as a backbone of the global economy. However, outbreaks onboard can disrupt maritime traffic, leading to significant economic and operational negative consequences. Without strong public health capacities to detect, prevent, and respond to public health risks on board ships, maritime travel can also become a pathway for the spread of infectious diseases.
To support countries in strengthening these capacities, the World Health Organization (WHO) convened a two-day webinar on 11–12 February, bringing together more than 700 ship inspectors, port health officers, and public health authorities, primarily from the African, Eastern Mediterranean, and European Regions.
The webinar came at a pivotal time. With the amended International Health Regulations entering into force on 19 September 2025, the need to focus on public health preparedness has never been greater. Strengthening public health capacities at borders, including onboard conveyances, is a cornerstone of global health security and central to the amended IHR.
“The high level of attendance and active participation throughout the two days of the webinar highlighted the growing demand for technical guidance and capacity-building support in ship inspection and issuance of ship sanitation certificates”, said Dr Ninglan Wang, Head of the Borders, Mass Gatherings and Health Protection Measures (BMM) Unit at the Health Emergency Preparedness Department at WHO headquarters. “The dynamic interactions among experts and countries underscored the value of continued cross-border collaboration in the maritime sector and knowledge exchange in this area”.
Conducting regular public health inspections on board ships for the issuance of ship sanitation certificates (SSCs) in accordance with the IHR requirements is crucial for ensuring that ships meet specific health standards, thereby minimizing the risk of the international spread of diseases via maritime traffic. These certificates, mandated by the IHR, require ports to have trained personnel who can identify and control public health risks on board vessels and apply recommended control measures. This standardized global procedure not only ensures compliance with the IHR but also promotes consistency in health practices across ports worldwide.
SSCs are the globally-recognized tool used to prevent and control known public health risks on ships, providing a common way to register and communicate public health events and measures taken on board between all stakeholders involved in this process, including public health authorities in ports and ship operators. Only SSCs issued by ports authorized by national authorities to issue such certificates are considered valid. As per the IHR, all States Parties are required to send to WHO their list of authorized ports (available here) and to keep it updated.
However, many Member States continue to face practical challenges, such as limited resources, high staff turnover, and competing priorities. These realities underscore the value of platforms such as this webinar, which foster collective learning, peer-to-peer exchange, and practical solutions to help countries build and sustain the capacities required under the IHR.
Over the two days, participants engaged in presentations and discussions covering a wide range of technical and operational topics, such as the overarching international legal framework governing ship sanitation; considerations for pre-inspection planning; risk assessment factors by type of vessel; the completion and issuance of SSCs and evidence report forms; or practical insights on the inspection of various technical areas, such as food safety, medical facilities, water systems, or vector control, among others.
In addition, public health authorities from the Netherlands, Morocco, and Tanzania shared case studies to showcase their practical application of these IHR requirements in their respective countries.
Given its success, WHO plans to replicate similar sessions in the future to reach additional time zones and regions and cover other pressing border health-related topics, ensuring that Member States can continue benefiting from these opportunities to share knowledge and expertise.
