RESUMEN
OBJECTIVES: The objective of this study was to assess the population prevalence of SARS-CoV-2 and changes in the prevalence in the adult general population in Estonia during the 1st year of COVID-19 epidemic. STUDY DESIGN: This was a population-based nationwide sequential/consecutive cross-sectional study. METHODS: Using standardised methodology (population-based, random stratified sampling), 11 cross-sectional studies were conducted from April 2020 to February 2021. Data from nasopharyngeal testing and questionnaires were used to estimate the SARS-CoV-2 RNA prevalence and factors associated with test positivity. RESULTS: Between April 23, 2020, and February 2, 2021, results were available from 34,915 individuals and 27,870 samples from 11 consecutive studies. The percentage of people testing positive for SARS-CoV-2 decreased from 0.27% (95% confidence interval [CI] = 0.10%-0.59%) in April to 0.04% (95% CI = 0.00%-0.22%) by the end of May and remained very low (0.01%, 95% CI = 0.00%-0.17%) until the end of August, followed by an increase since November (0.37%, 95% CI = 0.18%-0.68%) that escalated to 2.69% (95% CI = 2.08%-2.69%) in January 2021. In addition to substantial change in time, an increasing number of household members (for one additional odds ratio [OR] = 1.15, 95% CI = 1.02-1.29), reporting current symptoms of COVID-19 (OR = 2.21, 95% CI = 1.59-3.09) and completing questionnaire in the Russian language (OR 1.85, 95% CI 1.15-2.99) were associated with increased odds for SARS-CoV-2 RNA positivity. CONCLUSIONS: SARS-CoV-2 population prevalence needs to be carefully monitored as vaccine programmes are rolled out to inform containment decisions.

OBJECTIVE: Assess hepatitis C virus (HCV) prevalence and incidence among person who began injecting drugs during the opioid epidemic in New York City (NYC) and identify possible new directions for reducing HCV infection among persons who inject drugs. METHODS: 846 persons who began injecting drugs between 2000 and 2017 were recruited from persons entering Mount Sinai Beth Israel substance use treatment programs. A structured interview was administered and HCV antibody testing conducted. Protective effects of non-injecting drug use were examined among persons who "reversed transitioned" to non-injecting drug use and persons who used non-injected heroin in addition to injecting. RESULTS: Participants were 79% male, 41% White, 15% African-American, 40% Latinx, with a mean age of 35. Of those who began injecting in 2000 or later, 97 persons (11%) "reverse transitioned" back to non-injecting drug use. Reverse transitioning was strongly associated with lower HCV seroprevalence (30% versus 47% among those who continued injecting, p < 0.005). Among those who continued injecting, HCV seropositivity was inversely associated with current non-injecting heroin use (AOR = 0.72, 95%CI 0.52-0.99). HCV incidence among persons continuing to inject was estimated as 13/100 person-years. HCV seropositive persons currently injecting cocaine were particularly likely to report behavior likely to transmit HCV. CONCLUSIONS: Similar to other locations in the US, NYC is experiencing high rates of HCV infection among persons who have begun injecting since 2000. New interventions that facilitate substitution of non-injecting for injecting drug use and that reduce transmission behavior among HCV seropositives may provide additional methods for reducing HCV transmission.

This study used data from the International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) to estimate the quality of life (QoL) impact of fracture. Hip, vertebral, and distal forearm fractures incur substantial QoL losses. Hip and vertebral fracture results in markedly impaired QoL for at least 18 months. INTRODUCTION: The International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) is a multinational observational study that aims to describe costs and quality of life (QoL) consequences of osteoporotic fractures. To date, 11 countries have participated in the study: Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain, the UK, and the USA. The objective of this paper is to describe the QoL impact of hip, vertebral, and distal forearm fracture. METHODS: Data were collected at four time-points for five QoL point estimates: within 2 weeks after fracture (including pre-fracture recall) and at 4, 12, and 18 months after fracture. Quality of life was measured as health state utility values (HSUVs) derived from the EQ-5D-3L. Complete case analysis was conducted as the base case with available case and multiple imputation performed as sensitivity analyses. Multivariate analysis was performed to explore predictors of QoL impact of fracture. RESULTS: Among 5456 patients enrolled using convenience sampling, 3021 patients were eligible for the base case analysis (1415 hip, 1047 distal forearm, and 559 vertebral fractures). The mean (SD) difference between HSUV before and after fracture for hip, vertebral, and distal forearm fracture was estimated at 0.89 (0.40), 0.67 (0.45), and 0.48 (0.34), respectively (p < 0.001 for all fracture types). Eighteen months after fracture, mean HSUVs were lower than before the fracture in patients with hip fracture (0.66 vs. 0.77 p < 0.001) and vertebral fracture (0.70 vs. 0.83 p < 0.001). Hospitalization and higher recalled pre-fracture QoL were associated with increased QoL impact for all fracture types. CONCLUSIONS: Hip, vertebral, and distal forearm fractures incur substantial loss in QoL and for patients with hip or vertebral fracture, QoL is markedly impaired for at least 18 months.

UNLABELLED: We assessed the impact of hip fracture on health-related quality of life (HRQoL) and costs in Estonia. The mean 18-month HRQoL loss in quality adjusted life years (QALY) was estimated at 0.31, and the average cumulative cost from a societal perspective was 8146 euros per hip fracture patient. INTRODUCTION: The aim of this study is to estimate the impact of hip fracture on HRQoL, resource consumption, and cost over 18 months after the fracture among individuals aged over 50 in Estonia. METHODS: A cohort of 205 hip fracture patients ≥50 years was followed up for 18 months. HRQoL was estimated before fracture (recall), after fracture, and at 4, 12, and 18 months using the EQ-5D instrument. Health care utilization and costs were obtained from a public health insurance fund database; social, informal, and indirect costs were estimated using patient-reported data. RESULTS: Hip fracture resulted in the mean 18-month HRQoL loss of 0.31 QALYs. The mean 18-months cumulative cost of hip fracture from a societal perspective was estimated at 8146 (95 % CI 6236-10717) euros per patient. Most of the cost was related to health care (56 %) and informal care (33 %), while social care contributed only 5 %. Utilization of outpatient rehabilitation and nursing care was low (8 % of patients). CONCLUSIONS: The impact of hip fracture on HRQoL and cost was substantial. Despite appropriate inpatient care, utilization of rehabilitation, nursing care, and social care were low and potentially insufficient to meet the needs of patients with low HRQoL. The shortfall may partially explain a remarkably high use of informal care.

OBJECTIVES: To assess HIV/AIDS research productivity in the 27 countries of the European Union (EU), and the structural level factors associated with levels of HIV/AIDS research productivity. METHODS: A bibliometric analysis was conducted with systematic search methods used to locate HIV/AIDS research publications (period of 1 January 2002 to 31 December 2011; search databases: MEDLINE (Ovid, PubMed), EMBASE, ISI-Thomson Web of Science; no language restrictions). The publication rate (number of HIV/AIDS research publications per million population in 10â years) and the rate of articles published in HIV/AIDS journals and selected journals with moderate to very high (IF ≥3) 5-year impact factors were used as markers for HIV research productivity. A negative binomial regression model was fitted to assess the impact of structural level factors (sociodemographic, health, HIV prevalence and research/development indicators) associated with the variation in HIV research productivity. RESULTS: The total numbers of HIV/AIDS research publications in 2002-2011 by country ranged from 7 to 9128 (median 319). The median publication rate (per million population in 10â years) was 45 (range 5-150) for all publications. Across all countries, 16% of the HIV/AIDS research was published in HIV/AIDS journals and 7% in selected journals with IF ≥3. Indicators describing economic (gross domestic product), demographic (size of the population) and epidemiological (HIV prevalence) conditions as well as overall scientific activity (total research output) in a country were positively associated with HIV research productivity. CONCLUSIONS: HIV research productivity varies noticeably across EU countries, and this variation is associated with recognisable structural factors.

UNLABELLED: The incidence of hip fractures among individuals aged over 50 in Estonia and trends over time were assessed for 2005-2012. The incidence among women is relatively low, with the declining trend, but the rate among men is among the highest in Eastern and Central Europe. INTRODUCTION: The aim of this study was to assess the incidence and trends of hip fractures among individuals over 50 years in Estonia in 2005-2012 and to increase understanding of the incidence of hip fractures in Eastern Europe. METHODS: We identified all patients aged 50 years or older with hip fracture (ICD-10 codes S72.0, S72.1 and S72.2) in 2005-2012 using medical claims data from the Estonian Health Insurance Fund. Crude and age-specific incidence rates were calculated for men and women using the population of Estonia in 2005-2012. To adjust for age differences in the population, standardized incidence rates (SIR) were estimated. RESULTS: The SIR per 100,000 for the entire observation period was 209.2 (95% CI 204.2 to 214.2) in women and 215.6 (95%CI 208.2 to 223.1) in men, resulting in a female to male rate ratio of 0.97 (95% CI 0.84 to 1.11). Over the period of 2005-2012 the estimated SIR/100,000 ranged from 211.5 (95% CI 196.8-226.3) in 2005 to 183.7 (95% CI 170.8-196.7) in 2012 in women, and from 238.5 (95% CI 215.4-261.7) in 2005 to 187.9 (95% CI 169.0-206.8) in 2012, in men. For women, the decrease in SIR for the study period approached statistical significance (p = 0.058), and for the period of 2009-2012, we observed an accelerated 16% decrease (p = 0.008). CONCLUSIONS: The incidence of hip fractures among Estonian women is relatively low, whereas the rate among men is among the highest in Eastern and Central Europe. In line with many countries, we found a recent decline in incidence among women.

We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.0255.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

After 30 years of extensive research on human immunodeficiency virus (HIV) among persons who inject drugs (PWID), we now have a good understanding of the critical issues involved. Following the discovery of HIV in 1981, epidemics among PWID were noted in many countries, and consensus recommendations for interventions for reducing injection related HIV transmission have been developed. While high-income countries have continued to develop and implement new Harm Reduction programs, most low-/middle-income countries have implemented Harm Reduction at very low levels. Modeling of combined prevention programming including needle exchange (NSP) and antiretroviral therapy (ARV) suggests that NSP be given the highest priority. Future HIV prevention programming should continue to provide Harm Reduction programs for PWID coupled with interventions aimed at reducing sexual transmission. As HIV continues to spread in low- and middle-income countries, it is important to achieve and maintain high coverage of Harm Reduction programs in these locations. As PWID almost always experience multiple health problems, it will be important to address these multiple problems within a comprehensive approach grounded in a human rights perspective.
RESUMEN
The HIV epidemic in Estonia, as with other eastern European countries, is currently concentrated among injection drug users (IDUs). Non-IDUs who have IDU sex partners could serve as a potential bridge in an expanding epidemic. We applied HIV transmission modelling to data collected from non-IDU/IDU heterosexual couples in Kohtla-Järve, Estonia to estimate HIV risk from IDUs to their sex partners based on self-reported sexual behaviors shared by the couple. IDUs and their current main non-injecting sex partners were recruited for an interviewer-administered survey and HIV testing. Bernoulli modelling techniques were applied to estimate the risk of HIV transmission (incidence) among HIV negative non-injecting female partners of male IDUs. The estimated HIV incidence in this population of non-injecting women with only main sexual partners in the last 6 months ranged from 3.24 to 4.94 HIV seroconversions per 100 person years depending on the value used in the models for the per act transmission rate during acute stage infection. Non-IDUs who have IDU sex partners are at high risk for HIV and could serve as a potential bridge to a more generalized epidemic. Whether this might lead to an expansion of the HIV epidemic beyond core groups in Estonia or other Eastern European countries warrants closer study.

OBJECTIVES: HIV/AIDS risk is embodied within multiple levels including structural and social levels. The aim of this study was to assess the effects of neighbourhood characteristics on HIV prevalence among injection drug users (IDU) residing in the area of Tallinn, Estonia in 2007. METHODS: A cross-sectional, multilevel design collecting individual-level data--a behaviour survey including data on self-reported residency and HIV antibody testing among 350 IDU and neighbourhood-level data--aggregate measures on socio-demo-economic residential characteristics from the 2000 Estonian census. Geocoding and multilevel modelling analysis was employed. RESULTS: Among the 350 IDU recruited, earlier age at first injection, fentanyl as the main injection drug, receptive syringe sharing, main income source other than legal employment and ever attended a syringe exchange programme remained significantly associated with increased odds of anti-HIV positivity in the multivariable analysis involving individual effects with no predictors at the neighbourhood level. In the multilevel model, individual (earlier at IDU initiation AOR 1.86, 95% CI 1.01 to 3.44; injecting opioids AOR 4.43, 95% CI 2.74 to 7.18; receptive syringe sharing AOR 2.51, 95% CI 1.86 to 3.37; main income source other than work AOR 2.04, 95% CI 1.32 to 3.14; ever attended a syringe exchange programme AOR 2.58, 95% CI 1.83 to 3.61) and neighbourhood level (higher unemployment rate AOR 5.95, 95% CI 2.47 to 14.31; greater residential change AOR 1.89, 95% CI 1.09 to 3.26) emerged as significant predictors of individual HIV-positive status. CONCLUSIONS: Our results indicate that both individual-level and emergent neighbourhood-level factors contribute to HIV risk among IDU and are amenable for preventive interventions.

BACKGROUND: Sexually transmitted infections (STI) are a significant public health problem both worldwide and in Europe. This article reviews trends in the epidemiology of the major bacterial STI in eastern European countries, their key determinants, as well as challenges and opportunities for enhancing STI control in the region. SEARCH STRATEGY: Publications were sought through computerised searches in PubMed from 1995 to 2008 using using free text and relevant medical subject headings with no language restrictions. Conference abstracts and other unpublished manuscripts were excluded. RESULTS: The reported rates of STI in many eastern European countries have either decreased (syphilis and gonorrhoea in the eastern/Russian regions, gonorrhoea throughout eastern Europe) or been relatively stable (syphilis in the southeastern region, chlamydia throughout eastern Europe), in the past decade, but are still significantly higher than in western Europe. There is a significant east-west geopolitical gradient in reported STI rates throughout eastern Europe (STI rates: Russia/eastern region>>southeastern region>central region). Challenges for STI control include: the need to strengthen public health components of control; improvements in surveillance and improvement, as well as quality assurance, in diagnostic strategies. Gains in STI control may be achieved through greater collaboration and harmonisation of practicss at the European level.

We used the findings from two, cross-sectional studies of HIV serostatus and risk behaviours to assess the effects of knowledge of HIV serostatus and risk behaviours (relating to sex and injection drug use) among injecting drug users (IDUs). Respondent-driven sampling was used simultaneously at two sites in Estonia (the capital Tallinn, and the second-largest city of Ida-Virumaa County, Kohtla-Jarve). The research tool was an interviewer-administered survey. Biological samples were collected for HIV testing. Participants were categorised into three groups based on HIV testing results and self-report on HIV serostatus: HIV-negative (n=133); HIV-positive unaware of their serostatus (n=75); and HIV-positive aware of their serostatus (n=168). In total, 65% of the participants tested positive for HIV. Of those 69% were aware of their positive serostatus. HIV-positive IDUs aware of their serostatus exhibited more risk behaviours than their HIV-positive counterparts unaware of their serostatus or HIV-negative IDUs. Effective prevention of HIV among IDUs should therefore, include programmes to reduce high-risk sexual and drug use behaviours at the public health scale and enhanced prevention efforts focusing on HIV-infected individuals.

The aim of this study was to estimate the prevalence of Chlamydia trachomatis infection among Estonian men and women by a cross-sectional study based on the screening of a probability sample of the residents of Tartu using participant-collected, mail-delivered testing for C. trachomatis complemented with the self-administered questionnaire. Full participation as defined by returning both the questionnaire and specimen was 34% (n = 479; 95% confidence interval [CI] 32-37%). Study participation was 40% (n = 560; 95% CI 37-43%) for subjects returning either or both the study questionnaire and specimen. After weighing the population distribution, the prevalence estimate for the age group of 18-35 years was 5.4% (95% CI 3.0-7.5%), 6.9% (95% CI 3.6-10.3%) among women and 2.7% (95% CI 0.3-5.0%) among men. The number of sexual partners in the past 12 months was the strongest predictor of infection.

INTRODUCTION: Estonia is confronted by a dramatic expansion of the initially injection drug use-driven HIV epidemic. Little is known about HIV occurrence in population groups at high risk other than injection drug users. OBJECTIVE: To obtain data on the prevalence of HIV and hepatitis C virus (HCV) among female sex workers (FSW) in Tallinn. DESIGN: An unlinked, anonymous, cross-sectional survey of FSW recruited in Tallinn from October 2005 to May 2006. METHODS: 227 FSW were recruited for the survey and biological sample collection (HIV, HCV antibodies detection) using a combination of time-location, community and respondent-driven sampling. RESULTS: Among 227 women the HIV and HCV prevalences were 7.6% (95% CI 4.6% to 12.5%) and 7.9% (95% CI 4.5% to 12.6%), respectively. HIV prevalence was higher among FSW working in the street (odds ratio (OR) 6.4; 95% CI 1.1 to 35.6) and at the brothels and apartments supervised by the organised sex industry (OR 5.0; 95% CI 1.3 to 18.4). The duration of sex work was negatively associated with HIV prevalence (OR 0.78; 95% CI 0.63 to 0.97). CONCLUSIONS: Prevention needs of FSW in this area include increasing rates of HIV testing and putting in place effective programmes that can help extend HIV prevention behaviours across a range of sexual and drug use risk behaviours.

OBJECTIVE: This qualitative study assesses knowledge about sexually transmitted infections (STI), identifies perceived barriers to STI testing, and recommends strategies to optimise participation in a home based STI testing programme. METHODS: Five focus groups composed of 29 total participants were recruited using convenience sampling methods based on age (18-40 years), gender (male and female), and residency (Tartu region, Estonia). RESULTS: The focus groups revealed significant knowledge deficits and a widespread attitude of denial. However, participants acknowledged that STIs are a serious problem and recommended strategies for increasing participation in an STI testing and treatment programme. Successful STI prevention programmes must address a number of challenges, including disease stigmatisation and privacy protection. CONCLUSION: The fear of enforced disease control methods coupled with the current stigmatisation of STIs creates a serious challenge for Estonian STI prevention and treatment efforts. This qualitative study provides a good contextual reference for STI control programmes in eastern Europe.

BACKGROUND: It is important to describe and understand the underlying patterns and dynamics that govern sex work in societies undergoing rapid political and social changes, its heterogeneity across populations, and its evolution through time in order to inform future research, sound policy formation, and programme delivery. OBJECTIVES: To describe the socioeconomic and cultural determinants, organisational structure, distinct categories, and spatial patterning of sex work in Tallinn, Estonia, and identify recent temporal changes in sex work patterns. METHODS: In-depth interviews with key informants; naturalistic observations of sex work and drug use venues, geo-mapping of sex work sites, review of media, public policy, and commissioned reports, and analyses of existing data. RESULTS: Sex work takes place in a hierarchy of locations in Tallinn ranging from elite brothels and "love flats" to truck stops. These sites vary in terms of their public health importance and social organisation. There are full time, part time, and intermittent male and female sex workers. Among others, the taxi driver, madam and the bartender are central roles in the organisation of sex work in Tallinn. Cell phone and internet technology enable sex work to be highly dispersed and spatially mobile. CONCLUSION: Future research and programmatic service delivery or outreach efforts should respond to the changing profile of sex work in Tallinn and its implications for STD/HIV epidemiology.

BACKGROUND: The association between herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) and the development of HSV vaccines have increased interest in the study of HSV epidemiology. OBJECTIVES: To estimate the age and sex specific seroprevalence of HSV-1 and HSV-2 infections in selected populations in Brazil, Estonia, India, Morocco, and Sri Lanka. METHODS: Serum samples were collected from various populations including children, antenatal clinic attenders, blood donors, hospital inpatients, and HIV sentinel surveillance groups. STD clinic attenders were enrolled in Sri Lanka, male military personnel in Morocco. Sera were tested using a common algorithm by type specific HSV-1 and HSV-2 antibody assay. RESULTS: 13,986 samples were tested, 45.0% from adult females, 32.7% from adult males, and 22.3% from children. The prevalence of HSV-1 varied by site ranging from 78.5%-93.6% in adult males and from 75.5%-97.8% in adult females. In all countries HSV-1 seroprevalence increased significantly with age (p<0.001) in both men and women. The prevalence of HSV-2 infection varied between sites. Brazil had the highest age specific rates of infection for both men and women, followed by Sri Lanka for men and Estonia for women, the lowest rates being found in Estonia for men and India for women. In all countries, HSV-2 seroprevalence increased significantly with age (p<0.01) and adult females had higher rates of infection than adult males by age of infection. CONCLUSIONS: HSV-1 and HSV-2 seroprevalence was consistently higher in women than men, particularly for HSV-2. Population based data on HSV-1 and HSV-2 will be useful for designing potential HSV-2 vaccination strategies and for focusing prevention efforts for HSV-1 and HSV-2 infection.

BACKGROUND: Epidemiologic data document rapidly increasing sexually transmitted disease (STD) rates throughout Eastern Europe. GOAL: This case-control study was designed to delineate factors contributing to the STD epidemic in Estonia. STUDY DESIGN: For this study, 189 study participants and 112 control subjects completed a behavioral questionnaire and underwent testing for Neisseria gonorrhoeae, Chlamydia trachomatis, and Treponema pallidum. RESULTS: The prevalence of STDs among the control subjects was 32%. Although the participants believed that condoms prevent STDs, only 17% reported consistent use. Methods believed to prevent transmission included washing the genitals (65%), urinating (26%), douching (35%), and using oral contraceptives (19%). An interaction between sex and travel outside Estonia (odds ratio, 0.1; 95% CI, 0-0.7) reflects the fact that males with STDs were more likely to report travel (46% of participants and 45.5% of control subjects with STD) than were those without STD (16.1% of controls without STD). CONCLUSIONS: STD rates are related to high-risk sexual behavior among males traveling outside of Estonia. Intervention is needed to promote understanding of disease transmission dynamics in this area, and to decrease sexual risk behavior, particularly in the context of travel.

Sexually transmitted infections (STIs) are considered a major public health problem, globally. In particular, increasing STI rates have been documented throughout eastern Europe and central Asia. The Russian Federation and adjacent countries have, traditionally, managed STIs on an aetiological basis. This approach is expensive in terms of laboratory costs and it may lead to delayed diagnosis and treatment. To overcome the limitations of the aetiological management of STIs, the World Health Organization (WHO) has placed an increased emphasis on integrated care using syndromic management at the primary care level, especially in developing countries. This article reviews the current aetiology of STIs in Estonia, an eastern European country bordering the Baltic Sea and formerly a part of the Soviet Union, with the aim of defining whether infection with Trichomonas vaginalis is common enough to include its management in a syndromic management protocol. The use of syndromic management, in general, is also discussed.
