Pakistan, one of the last two endemic countries for wild polio, is closer than ever before to ending this devastating disease for good. However, many experts say Pakistan is among the countries most vulnerable to the climate crisis. As the world becomes hotter, more frequent and severe heatwaves, intense droughts, and devastating floods, threaten the incredible progress that has been made against polio.   

Just last year, from May to October 2022, a historic heat wave was followed by heavy monsoon rains and melting Himalayan glaciers, causing the worst floods in Pakistan’s history—almost one-third of the country was under water at its peak. One in seven people in the country were affected by these floods and close to eight million people were displaced, including thousands of polio workers themselves.
