The World Heatlh Organization (WHO) voted today to adopt the International Statistical Classification of Diseases and Related Health Problems (ICD-11), an update to what the WHO views as a serious diseases that includes a new entry called "Gaming disorder."
Gaming disorders are now part of a pair of "Disroders due to addictive behaviors" that also includes gambling disorders. While the WHO previously recognized gaming disorders as a disease back in June, today's vote officially adopts the ICD-11, making it the standard members of the WHO (which includes the United States along with much of the world) must use when making their own decisions about healthcare, treatment, prevention, and more going forward. Member nations must begin reporting health data using the ICD-11 by January 2022.
For reference, here is the official entry on gaming disorder in the ICD-11.
Also last June, the ESA responded to the WHO's recognition of gaming disorders as a disease with a statement opposing it, citing that "its inclusion remains highly contested an inconclusive."
