“…26 Hepatitis A vaccination should be recommended to all those travelling to countries with high or intermediate risks of hepatitis A. 27,28 Hepatitis A infection constitutes one of the most common VPDs in international travellers. 5,6 The relative risk of hepatitis A for travellers Research Highlights remains significant although there is up to 50 fold decrease of hepatitis A incidence in travellers during the last few years.…”

Introduction During that past few decades, international travel has dramatically increased worldwide. The number of international tourists is expected to reach a total of 1.6 billion by the year 2020. Travel to Africa recorded a growth of 2%. 1 International travels to tropical and subtropical countries may increase the risk of exposure to infectious diseases and may facilitate their global spread. 2,3 Sub-Saharan Africa is one of the most common destinations (26.7%) where illnesses are acquired by travellers. 4 A large proportion of imported infectious diseases to developed countries, including Greece, are related to Vaccine-Preventable Diseases (VPDs). 5,6 VPDs account for 3% of febrile episodes. According to GeoSentinel data; typhoid fever, hepatitis A, and influenza A were the most common VPDs. 6,7 Therefore, vaccine prophylaxis is an important measure of pre-travel advice. Risk assessment is based on travel variants such as destination, purpose, duration, area and place of travel and travellers' variants including age, medical and vaccination history. Recommendation of vaccinations prior to travel is based on risk assessment and includes routine vaccines (vaccines recommended by the national immunization program), required vaccines, according to the International Health Regulation (IHR), and recommended vaccines. 8 The current study aimed at assessing pre-travel preparation and provision of vaccinations to international travellers from Greece visiting http://ijtmgh.com

“…Recent data have shown that the overall risk ratio for HAV in travellers from industrialized to developing countries has decreased from 1:300 to 1:3000 in unimmunized travellers per month of stay [24]. However, the potential of common source outbreaks and subsequent person to person transmission in developing countries with shifting epidemiology continues to expose unprotected travellers to HAV.…”

For the first time a global meeting on hepatitis A virus (HAV) infection as vaccine preventable disease was organized at the end of 2007. More than 200 experts from 46 countries gathered to investigate the changing global HAV epidemiology reflecting the increasing numbers of persons at risk for severe clinical disease and mortality from HAV infection. The benefits of childhood and adult hepatitis A (HepA) vaccination strategies and the data needed by individual countries and international health organizations to assess current HepA prevention strategies were discussed. New approaches in preventing HAV infection including universal HepA vaccination were considered. This introductory paper summarizes the major findings of the meeting and describes the changing epidemiology of HAV infections and the impact of HepA vaccination strategies in various countries. Implementation of HepA vaccination strategies should take into account the level of endemicity, the level of the socio-economic development and sanitation, and the risk of outbreaks. A stepwise strategy for introduction of HepA universal immunisation of children was recommended. This strategy should be based on accurate surveillance of cases and qualitative documentation of outbreaks and their control, secure political support on the basis of high-quality results, and comprehensive cost-effectiveness studies. The recognition of the need for increased global attention towards HepA prevention is an important outcome of this meeting.

“…VFRs, especially children, are a major contributor to hepatitis A cases in Europe and North America. Studies from Europe and Quebec have found that VFRs account for 28%-78% of travel-related HA cases (30,32,33,34,35).…”

Background: Travellers intending to visit friends and relatives (VFRs) are a specific group of travellers who have been identified as having an increased risk of travel-related morbidity.Objective: To provide recommendations for risk reduction in international VFRs. Methods:Recommendations regarding VFRs were developed based on available travel medicine literature and CATMAT expert opinion. Specific travel-related risks, including infectious disease epidemiology and burden in this population, were reviewed and recommendations were provided to attempt to mitigate these risks. Previous CATMAT statements related to VFRs were referred to and reiterated.Recommendations: Rates of travel-related illness in VFRs tend to be higher for many conditions. Diseasespecific risk factors and recommendations are discussed throughout this Statement. CATMAT recommends that VFRs' vaccinations be up-to-date and they be counselled on the importance of various risk reduction activities such as the use of malaria prophylaxis, safe sex practices and injury prevention. Pre-and/or post-travel tuberculosis testing is indicated in certain situations. Conclusion:The pre-travel health assessment is an important opportunity to address with VFRs issues regarding health beliefs, health behaviours, current health status and the possibility of pre-existing conditions. Discussions addressing the importance of adherence to health advice and potential challenges to achieving adherence may be necessary. PreambleThe Committee to Advise on Tropical Medicine and Travel (CATMAT) provides the Public Health Agency of Canada with ongoing and timely medical, scientific, and public health advice relating to tropical infectious disease and health risks associated with international travel. The Agency acknowledges that the advice and recommendations set out in this statement are based upon the best current available scientific knowledge and medical practices and is disseminating this document for information purposes to both travellers and the medical community caring for travellers.Persons administering or using drugs, vaccines or other products should also be aware of the contents of the product monograph(s) or other similarly approved standards or instructions for use. Recommendations for use and other information set out herein may differ from that set out in the product monograph(s) or other similarly approved standards or instructions for use by the licensed manufacturer(s). Manufacturers have sought approval and provided evidence as to the safety and efficacy of their products only when used in accordance with the product monographs or other similarly approved standards or instructions for use.
