Characteristics of Polish travellers admitted at the University Centre of Maritime and Tropical Medicine in Poland, 2023.

BACKGROUND: After COVID-19 restrictions were lifted, people started to travel again. Each year, thousands of Poles travel internationally, and many travel to tropical or subtropical destinations in Asia, Africa or South America. The aim of this article was to describe the characteristics of Polish travellers based on the information from a retrospective 12-month review of the medical records of Polish patients seeking pre-travel advice at the largest diagnostic and treatment travel medicine centre in Poland in 2023. MATERIAL AND METHODS: The retrospective study was based on the analysis of medical records of 2,147 patients seeking pre-travel advice at the University Centre of Maritime and Tropical Medicine in Gdynia, Poland, between January and December 2023. The study focused on the analysis of the following patients' variables: age, sex, travel details (purpose of travel, length of travel, departure month, continents and countries to be visited). It also aimed to evaluate the range of prevention measures which were either recommended or administered to patients seeking pre-travel advice at the clinic (preventive vaccinations, chemoprophylaxis). In addition, it assessed the health status of the patients presenting at the travel medicine clinic; retrospective health assessments were based on the information from the interviews with the patients. RESULTS: Patients who sought pre-travel advice were mostly aged 36-65 years (49.5%), they were travelling for tourism purposes (78.3%), for a maximum period of 4 weeks (79.0%), mostly in November (15.2%) or in January (14.9%). Most travellers planned to visit Asia (55.5%) or Africa (29.0%); mainly Thailand (21.5%), Vietnam (8.5%), Kenya (8.3%) or India (8.2%). The most frequently administered immunoprophylaxis included vaccinations against typhoid fever and hepatitis A. Other commonly recommended/prescribed prevention measures included: insect repellents (69.3%), sunscreen (58.3%), antimalarials (35.8%), antithrombotic drugs (32.6%), and antidiarrheal drugs (25.6%). The analysis of patient interviews demonstrated that 61.8% of the travellers consulted at the clinic had no pre-existing medical conditions, while 38.2% required the use of chronic medications, mainly for allergies (14.3%), thyroid disorders (13.6%), cardiovascular diseases (9.3%), or psychiatric disorders (5.5%). CONCLUSIONS: A large number of Polish travellers visit destinations where the risk of infectious and non-infectious diseases is high. Providing patients with professional advice during a pre-travel consultation will help protect against travel-associated health problems.

How coronavirus disease will change the face of travel medicine.

PURPOSE OF REVIEW: The current article will review how the coronavirus disease 2019 pandemic has changed travel and travel medicine. RECENT FINDINGS: Travelers spread severe acute respiratory syndrome coronavirus 2 globally and continue to spread variants. The characteristics of the virus, the place, and time created a perfect storm that allowed the virus to quickly spread globally. The virus spread by every mode of travel with risk of transmission influenced by proximity to an infected person, duration of trip, physical characteristics of the space, and ventilation. Superspreading events were common; a small percentage of infected people accounted for most of transmission. The travel and tourist industry was devastated as lockdowns and quarantines severely restricted domestic and international travel. A trip includes multiple segments and shared sequential spaces, mostly indoors. Creating safe travel requires attention to all segments of a trip. SUMMARY: The coronavirus disease 2019 pandemic has affected every part of travel and travel medicine. The rapid development of multiple safe and effective vaccines and their deployment is allowing resumption of travel, yet many populations lack access to vaccines, and high levels of transmission continue in many areas. Providing documentation of vaccination or immunity in a consistent, verifiable, interoperable system is one of many active issues.

Travel distance reduces follow-up compliance but has no effect on long-term weight loss success in bariatric patients.

BACKGROUND: Patients seeking bariatric surgery are traveling longer distances to reach Bariatric Centers. The purpose of this study was to evaluate the impact of travel distance on adherence to follow-up and outcomes after bariatric surgery. METHODS: A retrospective review of all consecutive patients who had undergone bariatric surgery from June 2013 to May 2014 was performed, and the patients were divided into two groups: those who traveled 50 miles or less and those who traveled more than 50 miles. Primary outcome assessed was the influence of distance on post-operative follow-up attrition over 4-year period. Secondary outcomes assessed were excess weight loss, length of stay (LOS), complications and readmission rates. RESULTS: A total of 228 patients underwent bariatric surgery with 4 years of follow-up available. Of these, 145 patients traveled 50 miles or less and 83 patients traveled greater than 50 miles. Patient demographics were similar between the two groups. Those who traveled more had statistically higher probability of attrition up to 3-year follow-up mark. There was no difference in percent excess weight loss at each follow-up visit between the two cohorts. Furthermore, there was no difference in readmission rates (2% vs 5%), minor complications (14% vs 10%), major complications (3% vs 2%) and LOS (2.6 days vs 2.6). CONCLUSION: The distance patients traveled for bariatric surgery did not affect their weight loss success, length of stay, postsurgical complications or readmission rate. Despite the lack of influence on postoperative outcomes, follow-up compliance was statistically affected by distance.

Travellers' risk behaviors and health problems: Post-travel follow up in two travel medicine centers in Italy.

OBJECTIVES: We examined the association between travellers' characteristics, compliance with pre-travel recommendations and health problems. METHODS: Volunteer travellers were enrolled and data collected using a questionnaire between 30-60 days after returning home. We analyzed the associations through bivariate and multivariate models. RESULTS: Of the 468 enrolled travelers, 68% consumed raw food and 81% food containing milk and/or eggs. 32% consumed street vendor food and 30% drinks containing ice. 24% used the recommended mechanical prophylaxis measures. 46% got sick during and/or after travel (gastrointestinal symptoms most frequently). Factors predisposing to health problems were female gender, youth/middle age, intermediate travel duration and profession. The American continent and staying in hostels and tents were significantly associated with febrile illness. Street vendor food was significantly associated with skin reactions. CONCLUSIONS: Adherence to behavioral recommendations remains low. Travellers must be informed of health risks during and after travel.

Personal beliefs and misconceptions, not evidence guide general practitioners in the managing of travelers' diarrhea: Results from a pilot study (North-Western Italy, 2019).

BACKGROUND: The present study aims to characterize knowledge, attitudes and practices in a sample of general practitioners (GPs) on management of travelers' diarrhea (TD). METHODS: A total of 158 GPs (44.3% males; mean age 40.2±12.4 years) completed a web questionnaire on antibiotic prophylaxis (AP) and/or an antibiotic treatment (AT) in TD cases. Participants were inquired on knowledge status (KS), risk perception and effectively applied recommendations for AP/AT through a specifically designed questionnaire. Multivariate odds ratios (OR) for predictors of AP/AT were calculated through regression analysis. RESULTS: All in all, while 15 (9.5%) participants recommended AP for TD, 61 of them (39.4%) recommended AT. KS was largely unsatisfying as participants extensively ignored the most recent AP/AT recommendations. Acknowledgment of TD as a severe disorder was predictive for recommendation of AP (OR 37.843, 95%CI 4.752-301.4). As for AT, it was relatively elevated in GPs≥10 years (OR 2.653, 95%CI 1.169-6.019), but more rarely reported in participants with higher KS (OR 0.056, 95%CI 0.021-0.153). CONCLUSIONS: Adherence of GPs to official recommendations for TD management was unsatisfying, particularly in older participants. Continuous Education of GPs should be improved by sharing up-to-date official recommendations on AT/AP for TD.

Public health emergencies of international concern: a historic overview.

RATIONALE: The International Health Regulations (IHR) have been the governing framework for global health security since 2007. Declaring public health emergencies of international concern (PHEIC) is a cornerstone of the IHR. Here we review how PHEIC are formally declared, the diseases for which such declarations have been made from 2007 to 2020 and justifications for such declarations. KEY FINDINGS: Six events were declared PHEIC between 2007 and 2020: the 2009 H1N1 influenza pandemic, Ebola (West African outbreak 2013-2015, outbreak in Democratic Republic of Congo 2018-2020), poliomyelitis (2014 to present), Zika (2016) and COVID-19 (2020 to present). Poliomyelitis is the longest PHEIC. Zika was the first PHEIC for an arboviral disease. For several other emerging diseases a PHEIC was not declared despite the fact that the public health impact of the event was considered serious and associated with potential for international spread. RECOMMENDATIONS: The binary nature of a PHEIC declaration is often not helpful for events where a tiered or graded approach is needed. The strength of PHEIC declarations is the ability to rapidly mobilize international coordination, streamline funding and accelerate the advancement of the development of vaccines, therapeutics and diagnostics under emergency use authorization. The ultimate purpose of such declaration is to catalyse timely evidence-based action, to limit the public health and societal impacts of emerging and re-emerging disease risks while preventing unwarranted travel and trade restrictions.

Aetiology of fever in returning travellers and migrants: a systematic review and meta-analysis.

BACKGROUND: Numerous publications focus on fever in returning travellers, but there is no known systematic review considering all diseases, or all tropical diseases causing fever. Such a review is necessary in order to develop appropriate practice guidelines. OBJECTIVES: Primary objectives of this review were (i) to determine the aetiology of fever in travellers/migrants returning from (sub) tropical countries as well as the proportion of patients with specific diagnoses, and (ii) to assess the predictors for specific tropical diseases. METHOD: Embase, MEDLINE and Cochrane Library were searched with terms combining fever and travel/migrants. All studies focusing on causes of fever in returning travellers and/or clinical and laboratory predictors of tropical diseases were included. Meta-analyses were performed on frequencies of etiological diagnoses. RESULTS: 10 064 studies were identified; 541 underwent full-text review; 30 met criteria for data extraction. Tropical infections accounted for 33% of fever diagnoses, with malaria causing 22%, dengue 5% and enteric fever 2%. Non-tropical infections accounted for 36% of febrile cases, with acute gastroenteritis causing 14% and respiratory tract infections 13%. Positive likelihood ratios demonstrated that splenomegaly, thrombocytopenia and hyperbilirubinemia were respectively 5-14, 3-11 and 5-7 times more likely in malaria than non-malaria patients. High variability of results between studies reflects heterogeneity in study design, regions visited, participants' characteristics, setting, laboratory investigations performed and diseases included. CONCLUSION: Malaria accounted for one-fifth of febrile cases, highlighting the importance of rapid malaria testing in febrile returning travellers, followed by other rapid tests for common tropical diseases. High variability between studies highlights the need to harmonize study designs and to promote multi-centre studies investigating predictors of diseases, including of lower incidence, which may help to develop evidence-based guidelines. The use of clinical decision support algorithms by health workers which incorporate clinical predictors, could help standardize studies as well as improve quality of recommendations.

GeoSentinel: past, present and future†.

RATIONALE FOR REVIEW: In response to increased concerns about emerging infectious diseases, GeoSentinel, the Global Surveillance Network of the International Society of Travel Medicine in partnership with the US Centers for Disease Control and Prevention (CDC), was established in 1995 in order to serve as a global provider-based emerging infections sentinel network, conduct surveillance for travel-related infections and communicate and assist global public health responses. This review summarizes the history, past achievements and future directions of the GeoSentinel Network. KEY FINDINGS: Funded by the US CDC in 1996, GeoSentinel has grown from a group of eight US-based travel and tropical medicine centers to a global network, which currently consists of 68 sites in 28 countries. GeoSentinel has provided important contributions that have enhanced the ability to use destination-specific differences to guide diagnosis and treatment of returning travelers, migrants and refugees. During the last two decades, GeoSentinel has identified a number of sentinel infectious disease events including previously unrecognized outbreaks and occurrence of diseases in locations thought not to harbor certain infectious agents. GeoSentinel has also provided useful insight into illnesses affecting different traveling populations such as migrants, business travelers and students, while characterizing in greater detail the epidemiology of infectious diseases such as typhoid fever, leishmaniasis and Zika virus disease. CONCLUSIONS: Surveillance of travel- and migration-related infectious diseases has been the main focus of GeoSentinel for the last 25 years. However, GeoSentinel is now evolving into a network that will conduct both research and surveillance. The large number of participating sites and excellent geographic coverage for identification of both common and illnesses in individuals who have traversed international borders uniquely position GeoSentinel to make important contributions of travel-related infectious diseases in the years to come.

Travel Medicine: Clinical Updates in Women's Health Care Primary and Preventive Care Review.

Travel is an increasingly common aspect of modern life, and the practicing obstetrician-gynecologist needs a good understanding of the health- and safety-related issues it presents for patients. This monograph examines the environmental data that support individual risk assessment and provides guidance on how to eliminate or mitigate those risks, including recommendations for immunization and chemoprophylaxis for women traveling to areas with endemic infectious disease. Management approaches for travel-related diseases, such as traveler's diarrhea, altitude sickness, and location-specific diseases, are reviewed as are special considerations for pregnant and breastfeeding women and women who are attempting pregnancy. Evaluation and management of the returned traveler also is addressed. The recommendations in this document cite resources available from the United States federal government; therefore, they are applicable to women seeking care in the United States.

[Management of a global health crisis: first COVID-19 disease feedback from Overseas and French-speaking countries medical biologists]. / Gestion d'une crise sanitaire mondiale : premiers retours d'expérience de biologistes médicaux d'Outre-mer et de francophonie face au COVID-19.

The French society of clinical biology "Biochemical markers of COVID-19" has set up a working group with the primary aim of reviewing, analyzing and monitoring the evolution of biological prescriptions according to the patient's care path and to look for markers of progression and severity of the disease. This study covers all public and private sectors of medical biology located in metropolitan and overseas France and also extends to the French-speaking world. This article presents the testimonies and data obtained for the "Overseas and French-speaking countries" sub-working group made up of 45 volunteer correspondents, located in 20 regions of the world. In view of the delayed spread of the SARS-CoV-2 virus, the overseas regions and the French-speaking regions have benefited from feedback from the first territories confronted with COVID-19. Thus, the entry of the virus or its spread in epidemic form could be avoided, thanks to the rapid closure of borders. The overseas territories depend very strongly on air and/or sea links with the metropolis or with the neighboring continent. The isolation of these countries is responsible for reagent supply difficulties and has necessitated emergency orders and the establishment of stocks lasting several months, in order to avoid shortages and maintain adequate patient care. In addition, in countries located in tropical or intertropical zones, the diagnosis of COVID-19 is complicated by the presence of various zoonoses (dengue, Zika, malaria, leptospirosis, etc.).

Travel-screening documentation to enable the "Identify-Isolate-Inform" framework for emerging infectious diseases: It's all in the details.

The early phase of the coronavirus disease 2019 (COVID-19) pandemic and ongoing efforts for mitigation underscore the importance of universal travel and symptom screening. We analyzed adherence to documentation of travel and symptom screening through a travel navigator tool with clinical decision support to identify patients at risk for Middle East Respiratory Syndrome.

Tracking the spread of COVID-19 in India via social networks in the early phase of the pandemic.

BACKGROUND: The coronavirus pandemic (COVID-19) has spread worldwide via international travel. This study traced its diffusion from the global to national level and identified a few superspreaders that played a central role in the transmission of this disease in India. DATA AND METHODS: We used the travel history of infected patients from 30 January to 6 April 6 2020 as the primary data source. A total of 1386 cases were assessed, of which 373 were international and 1013 were national contacts. The networks were generated in Gephi software (version 0.9.2). RESULTS: The maximum numbers of connections were established from Dubai (degree 144) and the UK (degree 64). Dubai's eigenvector centrality was the highest that made it the most influential node. The statistical metrics calculated from the data revealed that Dubai and the UK played a crucial role in spreading the disease in Indian states and were the primary sources of COVID-19 importations into India. Based on the modularity class, different clusters were shown to form across Indian states, which demonstrated the formation of a multi-layered social network structure. A significant increase in confirmed cases was reported in states like Tamil Nadu, Delhi and Andhra Pradesh during the first phase of the nationwide lockdown, which spanned from 25 March to 14 April 2020. This was primarily attributed to a gathering at the Delhi Religious Conference known as Tabliqui Jamaat. CONCLUSIONS: COVID-19 got induced into Indian states mainly due to International travels with the very first patient travelling from Wuhan, China. Subsequently, the contacts of positive cases were located, and a significant spread was identified in states like Gujarat, Rajasthan, Maharashtra, Kerala and Karnataka. The COVID-19's spread in phase one was traced using the travelling history of the patients, and it was found that most of the transmissions were local.
