Introduction: Massive open online courses (MOOCs) are designed to accommodate large numbers of geographically dispersed learners. Few healthcare students receive exposure in travel medicine. We aimed as partner medical universities to develop a novel introductory MOOC in travel medicine suitable for undergraduate healthcare students, and to evaluate it among a cohort of learners. Methods: A course development team, comprising a senior travel medicine academic from National University of Ireland Galway, local International Medical University faculty and instructional/graphic designers, was convened in November 2017. The MOOC proposal was subsequently refined. Course construction commenced in December 2017 and involved communication between team members based in Malaysia and Ireland. Lectures were recorded in January-July 2018. Development of learning and assessment material and the pilot phase were completed in December 2019. Course evaluation was based on the results of a questionnaire and qualitative free text comments from users. Results: The MOOC is being delivered to a multinational cohort on a rolling basis. It is organised into five four-themed units: travel health risk assessment; pre-travel health advice; tropical infectious diseases; specialised travellers; and illness in returned travellers. Pedagogical methods include short video lectures, journal articles, a discussion forum, and self-assessment quizzes. Learners have the option of completing an online test to receive a certificate of achievement. Participant evaluation from the first run of the MOOC has revealed very high levels of satisfaction with content and mode of delivery. Conclusions This is the first MOOC in travel medicine and it may provide a model for development of other collaborative international e-learning courses. It will address a significant deficit in undergraduate health professional education.

BACKGROUND: Pre-travel medical consultation is essential to reduce health impairment during travel. Yellow fever vaccination (YFV) is mandatory to enter some endemic countries. In this study, we evaluated the factors that affect compliance with appropriate prevention of infectious diseases in travelers who visited clinic for YFV. METHODS: For this retrospective study, chart reviews for 658 patients who visited a travel clinic for YFV before travel were conducted. The period of this study was from January 2016 to September 2018. The associations between appropriate vaccination and factors such as travel duration, destination, time of visiting clinic before departure, and purpose of travel were analyzed. RESULTS: Among 658 patients who got YFV during the study period, 344 patients (52.3%) received additional vaccination or malaria prophylaxis following a physician's recommendation. Travelers who visited the clinic more than 21 days before departure were more compliant than those who visited 14 days or fewer before departure (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.23–2.93; P = 0.004). Travelers visiting Africa were more compliant than were those traveling to South and Central America (OR, 1.97; 95% CI, 1.34–2.90; P = 0.001). Travelers in age groups of 40-49 years and over 70 years were less compliant than the 18–29 years old population (OR, 0.51; 95% CI, 0.28–0.93; P = 0.027 and OR, 0.19; 95% CI, 0.04–0.84; P = 0.03, respectively). Also, those who traveled for tour or to visit friends or relatives were more compliant than those who departed for business (OR, 0.77; 95% CI, 1.03–3.56; P = 0.04). CONCLUSION: For appropriate vaccination, pre-travel consultation at least 3 weeks before departure is crucial. Travelers should be aware of required vaccination and malaria prophylaxis before visiting South and Central America and Asia. Plans to enhance compliance of the elderly and business travelers should be contrived.

OBJECTIVES: The 2017 guideline for the prevention of travelers' diarrhea (TD) by the International Society of Travel Medicine suggested that ‘there is insufficient evidence to recommend the use of commercially available prebiotics or probiotics to prevent or treat TD.’ However, a meta-analysis published in 2007 reported significant efficacy of probiotics in the prevention of TD (summary relative risk [sRR], 0.85, 95% confidence interval [CI], 0.79 to 0.91). This study aimed to synthesize the efficacy of probiotics on TD by updating the meta-analysis of double-blind, placebo-controlled, randomized human trials. METHODS: The search process was conducted by the adaptive meta-analysis method using the ‘cited by’ and ‘similar articles’ options provided by PubMed. The inclusion criteria were double-blind, placebo-controlled, randomized human trials with hypotheses of probiotics as intervention and TD as an outcome. The adaptive meta-analysis was conducted using Stata software using the csi, metan, metafunnel, and metabias options. RESULTS: Eleven articles were selected for the meta-analysis. The sRR was 0.85 (95% CI, 0.79 to 0.91) and showed statistical significance. There was no heterogeneity (I-squared=28.4%) and no publication bias. CONCLUSIONS: Probiotics showed statistically significant efficacy in the prevention of TD.

As air travelling now becomes cheaper and available to almost all people of any walk of life, travelling across international borders is fast becoming a lifestyle of many. Having travel health service as part of health care services is important to address the issues of travel related illnesses among travellers. However, lacks of published guidelines pertaining to travel health service rendering many countries to overlook its importance. The aim of this paper is to review published literatures and authoritative websites on the components needed to develop guideline to establish travel health services. A systematic literature search was done using pre-specified keywords for literatures published between years 2000 – 2016. Literatures written in English and fully accessible were all included. No exclusion criteria was set before the search. Online authoritative websites pertaining to travel health were also referred. A total of six literatures ranging from expert opinion, review paper and original study, together with three authoritative websites related to travel health were reviewed. Among the important components needed to be considered for developing the guideline for establishing travel health services are to prioritise pre-travel health service, to set up specialised travel health clinic, to produce travel health/medicine specialist, to emphasize on continuous education and training of the practitioners and to apply multiagency and multidisciplinary approach with adequate fund for research in travel health. As a conclusion, policy makers should prioritise and select the most important components in developing guideline for travel health service.

Travel-related health problems such as febrile illness have been reported in many travelers going to developing countries. With the emergence of new infectious diseases occurring in many parts of the world and their spread worldwide, early diagnosis of emerging infectious diseases or tropical diseases has become a very important part of controlling these diseases. In doing so, the itinerary of the ill returning traveler is crucial to formulating a differential diagnosis because exposure to pathogens differs depending on the area of travel. With up-to-date information on infectious diseases occurring worldwide, a differential diagnosis can be made by adding information on duration of travel, incubation period, underlying medical illness, history of prophylactic vaccines received, and knowledge of the patient's exposures during travel including insect bites, contaminated food or water, or freshwater swimming. Some travelers may have specific symptoms and signs such as fever, rash, or hemorrhagic manifestations. For example, eosinophilia suggests a possible helminth infection. In this article, the general approach to returnning travelers with suspected tropical disease will be described.

BACKGROUND: Travel-related risks for infectious diseases vary depending on travel patterns such as purpose, destination, and duration. In this study, we describe the patterns of travel and prescription of vaccines as well as malaria prophylaxis medication (MPM) at a travel clinic in South Korea to identify the gaps to fill for the optimization of pre-travel consultation. MATERIALS AND METHODS: A cohort of travel clinic visitors in 2011 was constructed and early one-third of the visitors of each month were reviewed. During the study period, 10,009 visited the travel clinic and a retrospective chart review was performed for 3,332 cases for analysis of travel patterns and prescriptions. RESULTS: People receiving yellow fever vaccine (YFV) (n = 2,933) were traveling more frequently for business and tourism and less frequently for providing non-medical service or research/education compared to the 399 people who did not receive the YFV. Overall, most people were traveling to Eastern Africa, South America, and Western Africa, while South-Eastern Asia was the most common destination for the non-YFV group. Besides YFV, the typhoid vaccine was the most commonly prescribed (54.2%), while hepatitis A presented the highest coverage (74.7%) considering the natural immunity, prior and current vaccination history. Additionally, 402 (82.5%) individuals received a prescription for MPM among the 487 individuals travelling to areas with high-risk of malaria infection. Age over 55 was independently associated with receiving MPM prescription, while purpose of providing service and travel duration over 10 days were associated with no MPM prescription, despite travelling to high-risk areas. CONCLUSION: Eastern Africa and South America were common travel destinations among the visitors to a travel clinic for YFV, and most of them were travelling for tourism and business. For the individuals who are traveling to areas with high-risk for malaria, more proactive approach might be required in case of younger age travelers, longer duration, and travel purpose of providing service to minimize the risk of malaria infection.

Since the 3rd WIN meeting in 1982 more than 500 participants join the meeting in Val D'Isere every year [1]. One of our authors has attended the meeting more than 10 times. He experienced many physical illnesses while travelling from South Korea to Val D'Isere in France, which is located in the Alps mountain near the border between France and Italy. In order to get there, it is necessary to take airplane, train, and/or bus with a heavy suitcase. During the trip which usually takes more than 15 hours, he experienced headache, gastrointestinal trouble, sleep disturbance and other additional physical illnesses. Therefore, we reviewed the itinerary to Val D'Isere and presented physical illnesses which occurred during a long trip for an academic activity by specialized professionals such as university hospital professors. In addition, we discussed the mechanism of such illnesses and offered possible solutions including medical treatment.

PURPOSE: Providing proper emergency medical services (EMS) for domestic or international visitors to popular destinations is becoming increasingly important. Jeju Island is the most visited spot in South Korea. The number of people visiting Jeju Island has increased every year, and this was over ten times the registered population on Jeju Island. The purpose of this study was to describe EMS use behavior and to estimate demand for EMS for visitors on Jeju Island. METHODS: A retrospective observational study was conducted on Jeju Island, with 580,000 citizens. EMS is a fire-based system with a single tiered intermediate service level by a single centralized dispatch center, 29 ambulances, and approximately 130 EMS providers. We collected all ambulance run-sheet data, which included comprehensive information as well as patients' address identification, monthly number of visitors, and census data of Jeju Island from January, 2010 to December, 2012. RESULTS: Among 90,674 EMS transports, 7,209 (8%) were excluded because of unknown address of patients, and of all 83,456 (100%) patients using EMS, 9,733 (12%) were visitors and 73,732 (88%) were residents. The percentage of females was higher for visitors than residents (45% vs. 43%, p<0.001) and the mean age was younger in visitors (38+/-19 vs. 54+/-22, p<0.001). Injury was much higher for visitors than residents (63% vs. 38%, p<0.001). The estimated monthly number of EMS use per 10,000 people was 3.7 (95% CI 3.5 to 3.9) in visitors and 35.7 (95% CI 34.9 to 36.5) in residents, with a ratio of 0.104 (95% CI 0.099 to 0.108). The trend of ratio by year was not significant (p=0.630). The correlation between monthly EMS use in visitors and monthly number of unregistered population was significant (Pearson's correlation 0.844). CONCLUSION: Determining EMS use behavior and the demand of EMS in visitors is a critical task. Our results are of interest in preparing and providing the provision of EMS for visitors.
