INERELA+ joins the International HIV/AIDS Alliance in noting its concern at the occupation and annexation of the Ukrainian territory of Crimea by Russia, and the subsequent announcement by Russian authorities that it intends to cease the opioid substitution therapy (OST) programme introduced in Crimea by the Ukraine government. Ukraine’s OST programme has been credited with a decrease in HIV incidence since 2007 among people who inject drugs. Russia’s sudden termination of Crimea’s OST programme will place hundreds of substance users in that region at risk of drug withdrawal and at increased risk of HIV infection. INERELA+ pledges its solidarity with the International HIV/AIDS Alliance in Ukraine (Alliance Ukraine) in calling for the Russian government to reconsider its stance on OST in Crimea.
