Global Influenza Surveillance and Response System

The Global Influenza Surveillance and Response System (GISRS) is an international network of laboratories and organizations that monitor flu activity worldwide. It collects and analyzes samples of the flu virus to detect new strains and track their spread. This information helps public health officials understand how the flu is changing, develop effective vaccines each year, and coordinate responses to prevent or control outbreaks. By sharing data globally, GISRS plays a crucial role in reducing the health impact of flu and preparing for potential pandemics.
