International consultant providing technical assistance for estimation of the drug users’ population size

Closing date

A. General description

In the Republic of Moldova the overall rate of newly diagnosed cases of HIV infection has continued to grow rapidly over the decade and is now the fourth highest of all countries in the region. By the end of 2020, the total number of new HIV cases registered in the country (including Transnistria) reached the figure of 14,380, ranging from about 700 (2009) to about 900 (2019) of new HIV cases registered annually. Information on the way of transmission was missing for 33% of newly diagnosed cases. Heterosexual transmission is reported to be the main way of transmission, with 90.3% of new cases reported in 2020, while transmission in case of injectable drugs use accounted for 3.1%, mother-to-child transmission - for 2.4% and cases of men having sex with men accounted for 4.2% of new cases.

The new National Program for HIV/AIDS and STIs Prevention and Control for the years 2021-2025 (NPM) which is in the process of approval by the Government of the Republic of Moldova provides for priority interventions within the national response to HIV/AIDS. Prevention of HIV infection, especially in key populations for achieving the UNAIDS 90-90-90 targets and effective management of the national program by coordinating the activities of all sectors and actors using effective monitoring and evaluation systems are among the main priorities of the national program. The effects of preliminary programmatic interventions, identification of the main priority preventive interventions in key populations, identification of risk groups can be done only on the basis of evidence collected during research and studies.

According to the Integrated Bio-Behavioral Survey (IBBS) of 2019/2020, the estimated HIV prevalence among IDUs was 11.4%; the estimated HIV prevalence among sex workers (SW) was 2.7%; the estimated HIV prevalence among men who have sex with men was 11.4%. According to the programmatic data, the indicators for covering the program with prevention services focused on IDUs were not achieved due to the changes on the drug market, transition to non-injectable use and massive appearance of new psychoactive substances (NPS). According to the IBBS 2019-2020 survey, in Chisinau municipality the most used drugs within the last 6 months were new psychoactive substances in the form of powder, crystals or pills mentioned by 55.4% of respondents and 33.5% of respondents from Balti municipality. Following the results of a study on the use of new psychoactive substances in Moldova and Belarus, the proportion of clients who switched from opium and amphetamines to the use of new psychoactive substances (NPS) by smoking or inhalation is increasing. For harm reduction programs, the main difficulty in working with consumers of non-injectable NPS is the impossibility of registering them as beneficiaries of the program, because, according to the regulations, injectable use is an essential criterion for their inclusion into the program. The absence of information on the extent of the drug use phenomenon, not just injectable drugs, and the absence of information on harm reduction services provided in case of non-injectable drugs use, including NSP, requires a number of activities regarding the estimation of the size of the drug users group based on existing sources or justification for conducting a research, which would help to improve the data set used for this purpose. The current NP involves activities aimed at a more detailed study and solution to this problem.
