The WHO Laboratory Biosafety Manual (4th edition) is a global reference for best practices in biosafety, widely adopted by clinical, public health, and biomedical laboratories. This edition emphasizes a risk-based approach, introduced in the previous edition, to ensure that biosafety measures match actual risks. The manual aims to help countries implement national codes of practice for handling biological agents safely. It promotes optimized resource use, sustainable biosafety and biosecurity policies, and equitable access to laboratory testing and research without compromising safety.
