This commentary calls on health care providers, social media platforms, professional bodies, and the public to identify and combat the spread of misinformation.

A global infodemic (an epidemic of misinformation) is spreading rapidly through social media and other outlets, creating serious obstacles to public health interventions. This misinformation is creating fear, confusion, and stigmatization, which may lead people to engage in dangerous practices. The World Health Organization is working to control the spread of misinformation, but it needs help from social media companies, health care providers, and others to be successful. Updated information must be disseminated from credible sources, and fact-checking must occur before sharing any information.
