Advocacy groups are accusing the government of embezzling millions of dollars in corrupt drug tenders and thus depriving patients of vital treatment.
Ukraine has one of Europe's biggest AIDS epidemics with about 1 percent of the adult population infected with HIV.
Ukraine is a leading recipient of aid from The Global Fund to Fight AIDS, Tuberculosis and Malaria, which covers about 10 percent of the country's needs, the rest coming from state coffers.
Of the estimated 450,000 Ukrainians who are HIV-positive, 70,000 require urgent treatment today. But only 28,000 are receiving it, leaving over 40,000 of patients without anti-retroviral therapy, which could greatly prolong their lives, according to WHO.
