WHO - Guidance on regulations for the transport of infectious substances, 2023-2024
applicable as from 1 October 2023
The safe transport of infectious substances is a critical component of global health security, requiring rigorous application of international regulations to prevent exposure risks to people and the environment. This guidance document provides a comprehensive and periodically updated framework to support compliance with regulatory requirements applicable as of 1 October 2023, drawing on international, regional and national instruments governing the transport of dangerous goods.
It outlines the processes for identifying, classifying and preparing infectious substances for transport, including distinctions between categories of risk and corresponding packaging, marking, labelling and documentation requirements. The document describes the roles and responsibilities of key stakeholders—such as shippers, carriers, packaging suppliers and receivers—and emphasizes the importance of training and coordination across the transport chain. It also aims to facilitate regulatory harmonization across jurisdictions by reflecting internationally recognized standards and modal agreements. In addition, it examines regulatory variations across transport modes, as well as procedures for managing incidents, ensuring security, and complying with customs and border controls. Intended for professionals involved in shipping infectious materials, this guidance supports the consistent and safe movement of biological substances across borders.
