SA athletes top Africa doping tablepublished at 09:30 British Summer Time 4 April 2017
More than 1,900 athletes were sanctioned for doping in 2015, new World Anti-Doping Agency figures show.
The 1,929 punishments for failed drug tests were an increase of 14% on the previous year, when 1,693 doping offences were carried out.
Wada says increased focus on investigations, intelligence gathering and whistleblowing are behind the rise.
South Africa had the sixth highest number of violations, with 59, the most of any African country.
