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:
1. the burden of disease and living conditions in their country of origin 2. experiences during migration, 3. access to health and labor4. factors relating to ethnicity and cultural practices5. burden of diseases in the country of reception Mobility itself doesn’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
1. Changes in the epidemiology of an infectious disease in a migrant’s country of origin.
2. Changes in migration patterns.3. Pre/post entry screening practices.4. Standard of living conditions in host country and associated risks of
onward transmission.5. Access to healthcare6. Level of case finding/diagnosis amongst different migrant groups 7. Reporting practices and changes to surveillance systems

STIs
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

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), aged between 18 and 69 hepatitis B virus surface antigen (HBsAg), the hepatitis B virus core antibody (anti-HBc)
and the 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-prospective study, 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 of chronic 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 of HBV infection in a sample of 3480 patients followed up during 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
Hepatitis B The study population consisted of
3353 (93.4%) adults at first visit 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 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
Migrant Health Care Project
‘Implementation of health care and psychosocial support activities for third-country nationals that may require international protection in the area of Evros-Greece’
Assessment visit to the Greek-Turkish border, ESCAIDE 2011 41
Background: Increased migration to the Greek-Turkish border
before 2009: 3,500
2009: 8,800
2010: > 47,000
2010: > 47,000
Background:Detention and Health Care
Greek law: persons without valid entry papers are detained in closed centres until ID verification
Prior to March 2011, health care was provided by local medical doctors NGO’s Hellenic Centre for Disease Control and Prevention
(KEELPNO)
Background: geographical locations
Fylakio detention, screening centre
Tychero police station
Soufli police station
Poros screening centre
Feres police station
Vena detention centre
Migrant Health Care Project Migrant Health Care (MHC) project became operational
in March 2011 funded by the European Union (EU) (80%) and by the
Greek national authorities (20%) AIM OF THE PROJECT
providing medical and psychosocial support to detained migrants
protecting public health through vaccination and screening of the newcomers
Migrant Health Care ProjectStaffing of the centres 7 physicians, 8 nurses, 5 psychologists, 3 social workers, 14
translators3 administrative staff ,3 drivers and 2 technical laboratory assistance
Entry assessment Medical file (medical history and clinical examination) Testing for tuberculosis, blood cell count, Haemorragic fever,
stool samples if diarrhea Psychosocial evaluation
Vaccination Children (< 18 y.): diphtheria, tetanus, pertussis, polio, measles,
mumps, rubella Adults: diphtheria, tetanus, polio
Early warning system
Surveillance of migrants, including an early warning component, had been set up
Surveillance network composed of the medical staff in the centres, doctors from the hospital and the project manager and the HCDCP
Telephone reporting daily Systematic documentation of health conditions is done after
release of migrants Alert notification was reported to be done by the medical staff in
the detention centres via telephone to the project manager and once a day in a regular basis
No outbreaks of communicable diseases had been reported during the visit
Most migrants were reported to be healthy individuals During the period of risk assessment, through screening two MDR
TB patients from Georgia were diagnosed
Migrant Health Care Project Demographical data
Time period: March-July 2011 (5 months) 6 stations and detention centers in Evros National
Border 6899 immigrants were screened in total 6278 (91%) were male and 621 (9%) were female,
258 minors Average age: males: 25.31, females: 44

MEDICAL INFORMATIONMantoux testing 1132 Mantoux tests were performed from which 88 (7.8%) were
positive
Vaccinations adults migrants were vaccinated against Poliomyelitis children against Diphteria, Tetanus, Pertussis and Poliomyelitis
and against Measles, Mumps and Rubella
Psychosocial evaluation

MEDICAL INFORMATION
Haemorrhagic fever testing
Of the 521 samples none was found + for IgM antibodies for Crimean-Congo H. Fever
Two had IgM+ and IgG+ antibodies for Dengue One had IgM+ and IgG+ for WNV One had IgM+ and IgG+ for Chickungunya virus
CONCLUSIONS Most of the migrants arriving were in a healthy status No outbreaks of communicable diseases were recorded in
detention centers There was an unexpectedly high percentage of pregnancies
and a substantial number unaccompanied minors, both of which are vulnerability factors
The percentage of positive Mantoux among screened migrants' shows that TB screening should be permanent on a daily basis
Practitioners should be aware that Heamorragic fever should be considered when migrants with arthralgia and fever seek for medical assistance in primary health care facilities

Key messages
Migration is a global phenomenon and a social determinant of health
In general, migrant populations are in a good physical condition (“the healthy migrant effect”) upon arrival to host countries
Undocumented migrants are special populations subjected to various health threats
Significant underreporting occurs for most communicable diseases, especially in these groups for plenty of reasons (fear of illegal status, limited access to health care, language and cultural barriers, fear of the loss of employment)
We need to strengthen surveillance systems in order to make prompt interventions and communicate to health professionals the special issues of migrant health
