GENPAR, or the Gender in Infectious Disease Epidemic Preparedness And Response Toolkit, is a set of benchmarks and tools to integrate gender into select core capacities of the International Health Regulations (IHR) 2005. GENPAR provides a set of actions (WHAT to do) as well as a range of tools (HOW to do it) to achieve each benchmark in integrating gender into the preparedness and response capacities covered by the toolkit. Using GENPAR, gender can be integrated into selected capacities step-by-step.
