Increasing childhood vaccination coverage of the refugee and migrant population in Greece through the European programme PHILOS, April 2017 to April 2018.

After the 2016 Balkan route border closures, vaccination of refugee children in Greece was mainly performed by non-governmental organisations. Activities varied between camps, resulting in heterogeneity of vaccination coverage (VC). In April 2017, the European programme 'PHILOS - Emergency health response to refugee crisis' took over vaccination coordination. Interventions were planned for the first time for refugee children in the community and unaccompanied minors at safe zones. From April 2017-April 2018, 57,615 vaccinations were performed against measles-mumps-rubella (MMR) (21,031), diphtheria-tetanus-pertussis (7,341), poliomyelitis (7,652), pneumococcal disease (5,938), Haemophilus influenzae type b (7,179) and hepatitis B (8,474). In April 2018, the vaccination status of children at camps (reception and identification centres and community facilities such as hostels/hotels were excluded) was recorded and VC for each disease, stratified by dose, nationality and camp size, was calculated. More than 80% of the children received the first MMR dose, with VC dropping to 45% for the second dose. For all other vaccines, VC was < 50% for the first dose in children aged 0-4 years and < 25% for the second dose. Despite challenges, PHILOS improved planning and monitoring of vaccination activities; however, further efforts towards improving VC in refugee children are needed.

Vaccination and malaria prophylaxis among Greek international travelers to Asian destinations.

BACKGROUND: International travel is rapidly increasing worldwide, and the greatest increases have occurred in tropical and subtropical areas. The aim of the survey was to investigate the pre-travel health-seeking practices of travelers to Asian destinations. METHODS: A questionnaire-based survey was conducted at the Athens International Airport between the 1st of November 2011 and the 30th of April 2013. RESULTS: A total of 1666 adult travelers participated in the study, and 69.7% were men. The mean age of the participants was 39 years. Previous travel to tropical countries was reported by 69% of the participants. The most frequent destination was the Indian subcontinent (45.0%). The main reasons for travel were visiting friends and relatives (VFRs; 36.5%) and business (32.4%). Most of the participants traveled for <1 month (51.4%). Only 24.5% pursued pre-travel consultations. Vaccinations were administered to 14.4% of the participants, and of those, 77%, 73%, and 32.5% received hepatitis A, tetanus/diphtheria, and typhoid vaccines, respectively. Malaria prophylaxis was given to 12.2% of the participants. Logistic regression analysis revealed that being male and unemployed, having an elementary level of education, traveling to visiting friends and relatives, and short durations of travel were significant determinants of not seeking pre-travel consultations. CONCLUSION: Significant gaps were revealed in the vaccinations and malaria prophylaxes of travelers departing to Asia. Specific educational tools should be developed to improve the awareness of travelers to high-risk destinations.

Vaccinations and malaria prophylaxis for long-term travellers travelling from Greece: a prospective, questionnaire-based analysis.

The purpose of this prospective, questionnaire-based study is to assess pre-travel vaccinations and malaria prophylaxis for long-term travellers who receive pre-travel advice in Greece. A total of 4721 travellers were studied from January 1, 2009 through December 31, 2012. Travellers sought pre-travel advice at a mean of 19.7 days (range: 0-349 days) before departure. Long-term travellers (≥ 1 month) accounted for 2205 (46.7%) of all travellers. Long-term travellers had a mean age of 34.5 years. The majority of them were men (79.8%). In terms of destinations, 84% were visiting malaria-endemic countries and sub-Saharan Africa was the most common destination (17.7%). Most long-term travellers pursued trips for work purposes (70%), visited urban areas (79.6%) and stayed in hotels (29.2%). Yellow fever, typhoid fever, hepatitis A and tetanus/diphtheria vaccines were administered to 1647 (74.7%), 741 (33.6%), 652 (29.5%), and 589 (26.7%) travellers, respectively. Yellow fever vaccine was administered to 339 (87%) and 132 (71%) of long-term travellers to sub-Saharan Africa and South America respectively, whereas typhoid vaccine to 119 (90.8%) and 330 (84.6%) of those travelling to the Indian subcontinent and sub-Saharan Africa respectively. Rabies vaccine was administered to 14 (0.6%) of them. Malaria prophylaxis was recommended to 446 (20%) of long-term travellers. Mefloquine was the most commonly (49%) prescribed agent, and was prescribed to 26.7% of long-term travellers to sub-Sahara Africa. In conclusion, this study revealed that recommendations for vaccine and malaria prophylaxis for long-term travellers to developing countries should be more selective, based on the assessment of all travellers' and travel characteristics, in order to provide adequate pre-travel preparation for this high risk group of travellers. More focused studies are suggested in order to understand the particular needs of long-term travellers. Increasing awareness of travellers and travel health consultants is very important.

Pre-travel preparation practices among business travellers to tropical and subtropical destinations: results from the Athens International Airport Survey.

BACKGROUND: The number of business travellers from Greece to tropical and subtropical areas has recently increased. The study aimed to assess travel health preparation practices of business travellers departing to Africa, the Middle East and Asia. METHOD: A questionnaire-based survey was conducted at Athens International Airport, from 1st of November 2011 to 30th of April 2013. RESULTS: A total of 684 business travellers participated in the study; the majority were men (86.1%), of Greek nationality (95.3%), with tertiary education (90.8%) and employed (98%). Their mean age was 40 years; 62% and 26% of them were 35-49 and 19-34 years of age respectively. 84.8% were travelling alone. Most frequent destinations were the Middle East (46.8%) and sub-Saharan Africa (16%). For 23.5% of the travellers it was their first trip to a tropical or subtropical country. Only 58.8% pursued pre-travel health consultation; vaccination and malaria chemoprophylaxis were administered to 24.7% and 25.7% of the travellers, respectively. Hepatitis A and typhoid vaccination rates were lower than expected (70% and 35%, respectively). Nearly half of the travellers who visited malaria endemic areas did not receive any chemoprophylaxis. Having elementary education level, travelling to the Middle East or North Africa, travelling for less than 1 month duration, and staying in a house or a hotel were associated with a higher probability of not pursuing health consultation. CONCLUSIONS: Significant gaps were found in pre-travel health practices of business travellers departing to Africa, the Middle East and Asia. Strategies should be developed in order to improve awareness of business travellers.
