Migrant Health Epidemiological Data in Greece Hellenic Center for Disease Control and Prevention 2012
Migration and Health-key issues • Migration is a global phenomenon • 3% of the world’s population resides permanently or temporarily outside their country of origin (World Bank, 2009) • Economic development and labor, urbanization, climate change, war and ethnic conflict are the main drivers
Migration and Health-key issues • Migrants may have more complex health needs than the native born population influenced by: • the burden of disease and living conditions in their country of origin • experiences during migration, • access to health and labor • factors relating to ethnicity and cultural practices • burden of diseases in the country of reception • Mobility itselfdoesn’t cause ill health • Migration should be considered a social determinant of health
Epidemiological data interpretation Factors that influence increases or decreases in infectious disease cases reported • Changes in the epidemiology of an infectious disease in a migrant’s country of origin. • Changes in migration patterns. • Pre/post entry screening practices. • Standard of living conditions in host country and associated risks of onward transmission. • Access to healthcare • Level of case finding/diagnosis amongst different migrant groups • Reporting practices and changes to surveillance systems
Migration and Health-main global health issues • Tuberculosis • HIV/AIDS • STIs • Hepatitis B and C • Malaria • Enteric fevers • Chagas disease • Chronic diseases?
Hellenic Centre for Disease Control and Prevention • Greek public health agency • Major operating component of the Ministry of Health HCDCP works with partners to: • monitor health • detect and investigate health problems • support research • implement prevention strategies • advocate sound public health policies
HIV/AIDS reporting system • Initiation of AIDS reporting: 1984 • Initiation of HIV reporting: 1998 • First AIDS diagnosis: 1981 • Number of reported HIV+ cases: 11,340 • Number of AIDS diagnoses: 3,235 • Number of deaths: 2,152 • HIV+ patients under treatment: 5,500
HIV cases by year of report and probable route of HIV transmission
Number of HIV infected IDUs in 2011 by nationality and year of report
Conclusions: HIV/AIDS Greece Steady increase in the reported numbers of new HIV cases during the last decade, both in native and non-native individuals 1/3 of new cases yearly occur in MSM HIV outbreak among IDUs in 2011 Paraskevis et al.: HIV-1 outbreak among injecting drug users in Greece,2011: a preliminary report, Euro Surveill. 2011;16(36):pii=19962
Sexually transmitted infections-STIs • The epidemiological surveillance of STIs is a task of KEELPNO’s office for HIV/AIDS and STIs. • The new surveillance system for STIs established in 2009 collects actively data (case-based and aggregated) on cases of gonorrhoea, syphilis, chlamydia and LGV. • Data is collected from clinicians/hospitals/laboratories in public and private sector. • Notification is mandatory by law • EU-2008 case definitions are used. • Significant underreporting from the private health sector
Sexually transmitted infections-STIs • Pilot program of enhanced epidemiologic surveillance for STIs “Andreas Syngros Dermatology and Venereal University Hospital, 2003-2009, sponsored by KEELPNO • 67.590visits for possible venereal disease • 3.288syphilis, gonorrhea, genital herpes and HIV diagnoses in total • 6.445diagnoses of HPV infection (condyloma acuminata)

Tuberculosis- issues to consider in the present and future • Underreporting • Review of current reporting form and reporting system • Surveillance of MTB resistance • Surveillance of the disease/therapy outcome • Implementation of the National Action Plan for Tuberculosis • Network of coordinators for the assessment of the implementation of the National Action Plan in peripheral level
Hepatitis B and C • Greece has been traditionally considered as a region of intermediate endemicity for HBV infection and estimated prevalence rates for HBsAg range from 3-5 % reaching 24% in certain rural areas. • First community based study in the general population of Greece, with a methodological approach based on multi-staged random sampling, was by Prof. Gogos et al. in EurJ Epidem 2003 • Rates: 2.1% rate of chronic HBV carriers, 0.5% antibodies to HCV
total of 130 immigrants (81 men and 49 women), agedbetween 18 and 69 • hepatitis B virus surface antigen(HBsAg), the hepatitis B virus core antibody (anti-HBc) andthe hepatitis C virus antibody (anti-HCV) were detected with ELISA method • the prevalence of HBsAg and anti-HBc was extremely high (15.4 % and 53.1 %, respectively), similar to that reported in countries of high endemicity for HBV infection • The prevalence of anti-HCV in the population of non-natives was relatively low (2.3 %) and no differences among various nationalities were found
Hepatitis B and C • HEPNET - GREECE (Hepatitis Network - Greece)for hepatitis B and C, is a multicenter nationwide retrospective-prospectivestudy, initiated in 2003 • sponsored by the Greek government, approved and conducted through the Hellenic Center for Disease Control and Prevention • Evaluation of the epidemiology and course ofchronic hepatitis B and C infection in Greece • 20 hepatology centers in Greece
Hepatitis B • HEPNET study for chronic hepatitis B (Journal of Viral Hepatitis, 2008) evaluated the epidemiological features ofHBV infection in a sample of 3480 patients followed upduring the years 1997–2006 • Baseline demographics, clinical and virological characteristics at their initial presentation at a hepatology centre • Evaluation of the characteristics of the disease amongst immigrants and Greek patients
The study populationconsisted of 3353 (93.4%) adultsat firstvisit and 127 (3.6%) children The majority of non-natives were born in Albania (71.0%) followed by Eastern European (19.4%) and Asian countries (3.2%) The majority of patients was of male gender, with an average age of 45 years, born in urban areas Immigrants were more frequently born in rural areas, were younger and with lower BMI compared to Greeks Adult immigrants had more frequently positive HBeAg compared to the Greek adults (10.6% vs 6.7%, P = 0.003 Hepatitis B
HEPNET study for chronic hepatitis BConclusions • Immigrants represented a considerable proportion (18.6%) of the total study population (and 56.6% of the children) • They were of younger age both at first visit (30.3 ± 14.2) and at first diagnosis of infection (28.4 ± 13.7) • Although aware of their disease before their first visit to the centre, did not seek medical advice due to ignorance about the seriousness of their disease • Patients from Albania were found to be the core immigrant population (13.7% out of 18.6%) • Most of adult natives and immigrants had similarly no known source of infection with intrafamilial spread accounting for 16.7% and 18.7% of the HBV transmission routes
