The Society for Healthcare Epidemiology of America (SHEA) wants to emphasize the importance of global partnerships in addressing health threats that impact all of us, as Americans and global citizens. We urge President Trump to reconsider the decision to terminate the U.S. relationship with the World Health Organization (WHO). The most effective way to address emerging health threats is through collaborative efforts with international partners. Eliminating U.S. involvement in the WHO would leave our country—and the world—more vulnerable to infectious diseases and less prepared to manage pandemics, fight emerging health threats, respond to chronic diseases, and improve infection prevention resources.
