LONDON/GENEVA—The chief scientist of the World Health Organization said on Nov. 15 she was leaving the agency, the first of a series of high-profile departures expected at the global health body as it prepares for a post-pandemic future.
The exit of Soumya Swaminathan, an Indian pediatrician, announced on Twitter, comes as Director-General Tedros Adhanom Ghebreyesus’s second term as leader of the 74-year-old U.N. agency gets underway. Swaminathan did not give a reason.
