Open letter to the WHO to put #TBontheList – “WHO: When you make a mistake, fix it,” former CDC head Dr. Tom Frieden tweeted last week, after TB research and response advocates reacted to the World Health Organization’s omission of tuberculosis from its a list of “priority pathogens” demanding urgent research and development efforts. Now the “dismay” expressed by the Stop TB Partnership the day the list was released has turned to demand, with a letter signed by 39 organizations and more than 250 TB leaders, clinicians, patients and advocates to WHO leaders calling for an immediate review and amendment to the list.
