Key interventions to prevent and control infections among people who inject drugs

Injecting drug use remains a crucial risk factor for acquiring blood-borne viruses such as hepatitis B and C, and HIV, but also other infectious diseases, such as sexually transmitted infections (STIs) and tuberculosis (TB). While for STIs and TB, injecting drugs does not directly cause infection, factors such as living conditions or higher-risk sexual practices place some people who inject drugs at a greater risk.

In new public health guidance released today, the European Centre for Disease Prevention and Control (ECDC) and the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) have joined forces to identify key interventions to address infectious diseases in this population. Reflecting on new evidence, infectious disease treatments, and public health concepts, this guidance updates the 2011 edition.

This joint guidance reinforces the need for a comprehensive and coordinated approach to addressing the persistent public health challenge of drug-related infections in EU/EEA countries. Ultimately, it aims to improve the well-being and health outcomes of individuals affected by these issues.

The guidance aims to support policy-makers and public health/social programme planners by providing an evidence base for developing national strategies, policies, and programmes for preventing and controlling infections and infectious diseases among people who inject drugs. It also provides practice considerations and aims to inform the monitoring and evaluation of prevention and control strategies, policies, and programmes.

The six key intervention areas and recommendations proposed in the guidance range from the provision of sterile injection equipment, testing, and vaccination, to the treatment of infections and drug dependence. They are:

  • Sterile injection equipment – provide sterile needles and syringes and other drug preparation equipment (cookers, filters and water for injection), including in prisons and through pharmacies.
  • Drug dependence treatment – provide opioid agonist treatment (OAT), including in prisons, for people who are dependent on opioids. OAT should be offered in conjunction with sterile injecting equipment and information, education, and counselling.
  • Vaccination – offer vaccinations against hepatitis A and B, respiratory infections and tetanus, as well as the pneumococcal and the human papillomavirus vaccines for people living with HIV who inject drugs.
  • Testing – routinely offer voluntary and confidential infectious disease testing and link all people with a positive test result to care.
  • Infectious disease treatment – offer infectious disease treatment according to national and international guidelines, ensure there is good cooperation and links between service providers dedicated to people who inject drugs and infectious disease care; involve peer mentors to strengthen adherence to treatment.
  • Drug consumption rooms – provide supervised injecting facilities to reduce injecting risk behaviour among people who inject drugs, which could as a consequence contribute to the prevention of HCV and HIV transmission.

Expert update on drug-related infectious diseases

The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) gathered the Drug-related infectious diseases (DRID) expert network to share the latest developments on drug-related infectious diseases in Europe and to identify steps needed to improve the production, availability and use of public health-oriented information at the European level.

The DRID network brings together national experts nominated by national focal points of the EU Member States, Norway and Turkey, as well as institutional partners (ECDC, WHO, Correlation). The meeting also welcomed experts from the Western Balkans (IPA7 project), the European Neighbourhood Policy countries (EU4MD project), Georgia, the United Kingdom, Australia and the United States. Participating experts come from ministries of health, public health institutes, drugs agencies, health services, universities, research institutes and civil society.

The group held an online meeting on 26-27 October 2021, focusing on:

  • The direct impact of COVID-19 on people who use drugs and the COVID‑19 vaccination campaign among this group;
  • A review of recent HIV trends and outbreaks, as well as infectious endocarditis linked to injecting drug use with a focus on risk factors and control measures in place;
  • Country experiences in the elimination of viral hepatitis as a public health threat among people who inject drugs (PWID) and related EMCDDA projects, with a focus on harm reduction and the continuum of care.

The report section on Outbreaks includes some interesting information from South East Europe.

In 2011, an HIV outbreak among PWID was detected in Athens, Greece (Paraskevis et al., 2011). After a combination of prevention and ‘seek-test-treat’ interventions were implemented (including scaled-up NSP, testing, linkage to AOT and antiretroviral treatment (ART), HIV incidence declined (Sypsa et al., 2017) from 7.8/100 person-years in 2012 to 1.7/100 person-years in 2013. However, preliminary data from the latest round of the ARISTOTLE study, conducted in 2018-20 (Roussos et al., 2021) among 681 PWID who were included in previous rounds, suggest that HIV prevalence increased from 14.2 % (2012-13) to 22 % (2018-20). While incidence estimates never returned to their 2011-12 levels, they ranged from 1.52 to 2.04/100 person-years, indicating ongoing transmission. The prevalence of homelessness (25.6 %) and cocaine injecting (28.1 %) had increased over the period. Predictors of seroconversion included lower education, larger network size and daily drug use. The authors concluded that the current level of prevention and treatment services was below levels that would be required to bring transmission down to pre-outbreak levels. They also noted that the COVID‑19 pandemic has severely impacted HIV prevention services for PWID, which could increase the risk of HIV transmission in this population. The study team conducted a similar study in Thessaloniki, the second-largest city in the country, where 1 101 PWID were recruited during 2019-20. They found high HIV incidence among the study population, suggesting that an outbreak was occurring at a time when COVID‑19 controls measures were in place. The authors highlighted that immediate interventions were required to control transmission.

Following the DRID meeting, national experts from three additional EU countries have reported signals of increased HIV transmission among people who use drugs. In Sofia, Bulgaria, reports indicate that the pandemic seems to have worsened a situation that was already deteriorating with respect to harm reduction funding. According to data from the laboratory at the State Psychiatric Hospital for Treatment of Drug Addiction and Alcoholism in Sofia, reported by the national expert, the positivity rate for HIV infection among PWID in the capital of Bulgaria was significantly higher in 2019-20 (12.8-14.5 %) than in the previous years (when positivity rates were between 3-6 %). A parallel increase in HBV positivity (HBsAg) was also noted from 2019 (5.9 %) to 2020 (7.6 %). This comes after the Global Fund ended its financial support to harm reduction services in 2017. It consequently led to a disruption in needle and syringe programmes, and a reduction by more than half in the number of PWID being tested annually. The National Centre of Public Health and Analysis is organising a meeting with stakeholders and decision-makers to initiate legal changes in order to ensure sustainable financial support for harm reduction services.

The national expert from Slovenia reported that, by November 2021, four new HIV diagnoses among PWID were reported to the National Institute of Public Health among a total number of 28 reported new HIV diagnoses during 2021. This raised concerns that HIV infections might have started to spread more during the COVID‑19 pandemic among PWID in the country. Since 1986, when HIV reporting became mandatory in Slovenia, a total of 29 HIV infections among PWID have been reported, and such a high number of cases (four) were reported only once before, in 1996. The importance of reaching a good coverage of harm reduction services for PWID was re-emphasised.

Drug-related infectious diseases in Europe

Excerpts from the EMCDDA press release

Testing for drug-related infectious diseases among people who inject drugs (PWID) is crucial if international health targets are to be met. This is among the conclusions of a new EMCDDA report Drug-related infectious diseases in Europe. The update, from the agency’s drug-related infectious disease network, stresses that early diagnosis through testing, and improving links to treatment and care, are crucial steps towards reaching global health goals.

Launched during European Testing Week (15–22 May), the report offers an overview of drug-related infectious diseases among PWID in Europe, including the prevalence and incidence of HIV and viral hepatitis. It also tracks progress on health targets and showcases successfully implemented evidence-based interventions. It underlines the need to ramp up prevention and testing and signals that European countries are lagging behind when it comes to treating hepatitis C virus (HCV) and HIV among PWID.

HIV and chronic viral hepatitis are highly prevalent among people who inject drugs, being transmitted through the sharing of injecting equipment, such as needles and syringes. Addressing the needs of this group is critical to achieve the UN Sustainable Development Goal of Good Health and Well-being (SDG 3), which calls for ending the AIDS epidemic and combatting viral hepatitis as a public health threat by 2030 (SDG 3.3).

Besides data which include SEE countries which are EU members, there is a small update from neighbouring countries within the Instrument for Pre-accession Assistance 7 and EU4Monitoring Drugs project:

The Instrument for Pre-accession Assistance (IPA) 7 technical cooperation project comprises six beneficiary countries: Albania, Bosnia and Herzegovina, Kosovo (1), Montenegro, North Macedonia and Serbia. Data on PWID and other key populations in the region are available from RDS seroprevalence studies: Albania, Kosovo and North Macedonia have conducted such surveys in the past 3 years; Bosnia and Herzegovina, Montenegro and Serbia are planning to collect data in 2020. There were no HIV-positive cases among PWID in recent surveys conducted in Kosovo or North Macedonia (Mikikj, 2017); older HIV prevalence estimates among PWID ranged between 0 % in Bosnia and Herzegovina in 2015 (Skocibusic et al., 2016) to 2 % in Serbia in 2013 (IPH Serbia, 2013). Most recent HCV infection prevalence estimates ranged from 23.8 % in Kosovo to 72 % in North Macedonia. All six beneficiaries are signatories of the Dublin Declaration.
