Global Prevalence of Injection Drug Use-Related HIV

"Injecting drug use is estimated to account for approximately 10 per cent of HIV infections worldwide and 30 per cent of all HIV cases outside Africa,113 while in the eastern countries of the WHO European Region114 more than 80 per cent of all HIV infections occur among PWID.115 PWID are estimated to be 22 times more likely than people in the general population to be living with HIV.116

"The 2018 joint UNODC/WHO/UNAIDS/World Bank estimate of the global prevalence of HIV among PWID is 12.6 per cent, amounting to 1.4 million PWID living with HIV. This estimate is based on reporting of the prevalence of HIV among PWID by 121 countries, covering 96 per cent of the estimated global number of PWID. Data on HIV prevalence were available for all PWID in North America, South-West Asia, South Asia, Eastern Europe and South-Eastern Europe, but only for 33 and 32 per cent of all PWID in Central America and the Caribbean, respectively. Of all the countries that provided details of the methodology used to collect their data and estimate the prevalence of HIV, almost three quarters (reports from 89 countries) could be graded as “class A methodology” (seroprevalence study).117 In 2018, new or updated estimates of HIV among PWID were available for a total of 40 countries."
