The World Health Organization's international list of diseases is getting an update. In its revised International Classification of Diseases released Monday, the WHO removed transgender identity as a mental health disorder and added gaming disorder to the list. Recategorizing transgender as a sexual health condition is aimed at cutting stigma and improving quality of care, says the WHO. The WHO first considered declassifying "gender incongruence" in July 2016, The New York Times reports, but didn't make the change officially until the Monday release of the ICD-11, the WHO's first revision to its list of diseases in 28 years.
