45,482.

That is the number of rape survivors treated by Dr. Denis Mukwege and his associates at Panzi Hospital between 1999 and 2015. Some 35,000 of those survivors, who range in age from toddlers to seniors, suffered complex gynecological injuries, inflicted by members of rebel groups and the Congolese military.
