Independent studies have arrived at almost identical estimates of the human costs of HIV/AIDS denialism in South Africa. According to a paper written by researchers from the Harvard School of Public Health, between 2000 and 2005, more than 330,000 deaths and an estimated 35,000 infant HIV infections occurred "because of a failure to accept the use of available drugs to prevent and treat HIV/AIDS in a timely manner." Nicoli Nattrass of the University of Cape Town estimates that 343,000 excess AIDS-related deaths and 171,000 infections resulted from the Mbeki administration's policies, an outcome she refers to in the words of Peter Mandelson as "genocide by sloth".
