Rotary brings together a global network of volunteer leaders dedicated to tackling the world's most pressing humanitarian challenges. Rotary connects 1.2 million members of more than 34,000 Rotary clubs in over 200 countries and geographical areas. Their work improves lives at both the local and international levels, from helping families in need in their own communities to working toward a polio-free world. In 1988, Rotary was joined by the WHO, UNICEF and the CDC to launch the Global Polio Eradication Initiative.
