Advising the immunocompromised traveller: a review of immunocompromise at The London Hospital for Tropical Diseases Travel Clinic between 1st April 2019 and 30th April 2020. Trop Dis Travel Med Vaccines 2024; 10:8. [PMID: 38616263 PMCID: PMC11017494 DOI: 10.1186/s40794-024-00217-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Accepted: 01/09/2024] [Indexed: 04/16/2024] Open
Abstract
BACKGROUND Immunocompromised travellers (ICTs) face greater infectious and non-infectious travel-associated risks than their immunocompetent counterparts. Increasing travel and emergence of novel immunosuppressants poses great challenges for travel medicine practitioners to confidently provide up-to-date evidence-based risk management advice and pre-travel care for ICTs. METHODS We reviewed the records of ICTs attending the London Hospital for Tropical Diseases (HTD) Travel Clinic between 1st April 2019 and 30th April 2020 with the aim to describe demographic and travel characteristics, type, and severity of immunocompromise, the degree of risk associated with intended travel and evaluate travel advice. RESULTS Of the 193 ICTs identified, immunocompromise was due to physiological reasons (42%), chronic infection (17.1%) and immunosuppressive therapy (16.6%). Median age was 38 (range 9 months to 84 years) and male to female ratio 0.75 (83:110). Travel was intended to 80 countries for a median of 16 days (range 2 to 3167), predominantly for leisure (53%), non-medical work (17%) and visiting friends and relatives (12%). Live vaccine safety dominated discussion in the pre-travel consultation. Existing guidelines arguably fell short in dealing with travel risks associated with hyper-specific conditions, targeted immunosuppressants and non-vaccine preventable infections. CONCLUSIONS Our cohort represents a wide spectrum of immunocompromise, for whom we arguably need more measurable ways to approach travel-associated risks. We propose prospective qualitative participatory research to inform our unit of the priorities of ICTs in the pre-travel consultation. We further recommend the formation of a repository of specialists and formulary of complex cases to direct subsequent informative systematic review and prospective risk studies.

Abstract
Although the impact of tourism development on residents has received a lot of attention in the literature, the health impact of tourism has not been sufficiently addressed. Due to outbreaks of COVID-19, the importance of recognition of the negative health impact of tourism is relevant. Thus, the present study aims to identify the health impact of tourism through COVID-19 outbreaks considering residents' perspectives. In the current research, we gathered data from semi-structured interviews conducted from 10th August to 30 August 2020 to investigate community perception regarding the negative health impact of tourism through the COVID-19 era. We conducted 30 interviews with some Iranian residents. Data is analyzed by thematic analysis via MAXQDA software. Residents perceived negative health impacts through COVID-19 outbreaks as containing three subthemes including general negative impacts, direct negative impacts, and indirect negative impacts. The results also show that residents use two coping strategies to face these negative health impacts, namely negative coping strategies and positive coping strategies. Perceived negative health impacts, and residents' coping strategies are two major themes regarding Iranian residents' perception toward tourism negative health impacts through COVID-19 outbreaks.

Chinese Tourists’ Health Risk Avoidance Behavior in the Context of Regular Epidemic Prevention and Control: An Empirical Analysis. SUSTAINABILITY 2022.

Abstract
The health risk avoidance behavior of tourists in China, a country actively combating COVID-19, is of research significance. This study proposes and tests a model based on three theories—stimulus-organism-response model, motivation-opportunity-ability model, and health belief model—to examine the impact mechanism of tourists’ health risk avoiding behavior under COVID-19′s regular epidemic prevention and control situations and the moderating effect of health risk perception. The results reveal that, from the stimulus perspective, tourists’ motivation, opportunities to travel, and the ability to travel negatively affect tourists’ health risk avoidance behavior. That is to say, the stronger the motivation of tourists to undertake tourist activities, the stronger the safeguards provided by the government, and the better that tourists are informed of the virus and more equipped with healthy habits and skills, the more likely it is that tourists will not take avoidance behavior. From the organism perspective, perceived severity and perceived susceptibility, as mediating factors, positively influence tourists’ health risk avoidance behavior. In contrast, if tourists are more likely to believe in the controllability of the health risk of the epidemic, then they are more likely to travel and less likely to show avoidance behavior. Managerial implications and theoretical contributions are also provided.

Abstract
Travellers' diarrhoea (TD) is the most frequent illness experienced by international travellers to lower-income countries with bacterial agents considered to account for 80-90% of cases. In this review, we summarise evidence published on bacterial TD over the past 10 years, focusing on the epidemiology and aetiology of TD. Diarrhoeagenic Escherichia coli (DEC) continue to be the most commonly implicated bacteria in TD, although Enteropathogenic E. coli (EPEC) and Enteroaggregative E. coli (EAEC) now appear to be predominant where Enterotoxigenic E. coli (ETEC) was previously considered most prevalent globally. Where fluroquinolone resistance had primarily been documented for Campylobacter in Southeast Asia, widespread resistance has been observed in most regions of the world for multiple enteropathogens, including Shigella, Salmonella, ETEC and EAEC. Implementation of novel molecular methods for pathogen detection has led to identification of bacterial pathogens, including Clostridium difficile (with and without the use of prior antibiotics), Arcobacter species and Bacteroides fragilis, as aetiological agents in TD. The widespread resistance to first-line antibiotics in multiple bacterial enteropathogens warrants continued surveillance and re-evaluation of current treatment practices. Further investigations are required to determine the prevalence and geographical distribution of bacterial enteropathogens that have been more recently implicated in TD.

PLoS One 2022; 17:e0262571. [PMID: 35061808 PMCID: PMC8782361 DOI: 10.1371/journal.pone.0262571] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Accepted: 12/29/2021] [Indexed: 12/22/2022] Open
Abstract
Backgrounds and aims Inflammatory bowel disease (IBD) patients often experience disease flare-ups during international air travel. We aimed to identify risk factors associated with IBD flare-up during international air travel. Methods Patients with scheduled international air travel were enrolled in the study from the Seoul National University Bundang Hospital IBD clinic. Flight information and clinical data were collected via questionnaires and personal interviews, and risk factors associated with IBD flares were determined. Results Between May 2018 and February 2020, 94 patients were prospectively enrolled in the study (mean age, 33.0 years; males, 53.2%; mean disease duration, 56.7 months), including 56 (59.6%) with ulcerative colitis and 38 (40.4%) with Crohn’s disease. Of the 94 patients enrolled, 15 (16.0%) experienced an IBD flare-up and 79 (84.0%) remained in remission throughout travel. Logistic regression analysis revealed that high fecal calprotectin levels before travel (odds ratio [OR]: 1.001, 95% confidence interval [CI]: 1.000–1.001, p = 0.016), the presence of a comorbidity (OR: 6.334, 95% CI: 1.129–35.526, p = 0.036), and history of emergency room visit (OR: 5.283, 95% CI: 1.085–25.724, p = 0.039) were positively associated with disease flare-up. The previous and current use of immunomodulators and biologics, time of flight, altitude, number countries visited, travel duration, objective of visit, and previous medical consultations were not associated with disease flare-up. Conclusions Elevated fecal calprotectin levels, history of emergency room visits, and the presence of a comorbidity predicted IBD flare-up during international air travel.

Travel-related infections presenting in Europe: A 20-year analysis of EuroTravNet surveillance data. LANCET REGIONAL HEALTH-EUROPE 2021; 1:100001. [PMID: 35081179 PMCID: PMC8454853 DOI: 10.1016/j.lanepe.2020.100001] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 02/06/2023]
Abstract
Background Disease epidemiology of (re-)emerging infectious diseases is changing rapidly, rendering surveillance of travel-associated illness important. Methods We evaluated travel-related illness encountered at EuroTravNet clinics, the European surveillance sub-network of GeoSentinel, between March 1, 1998 and March 31, 2018. Findings 103,739 ill travellers were evaluated, including 11,239 (10.8%) migrants, 89,620 (86.4%) patients seen post-travel, and 2,880 (2.8%) during and after travel. Despite increasing numbers of patient encounters over 20 years, the regions of exposure by year of clinic visits have remained stable. In 5-year increments, greater proportions of patients were migrants or visiting friends and relatives (VFR); business travel-associated illness remained stable; tourism-related illness decreased. Falciparum malaria was amongst the most-frequently diagnosed illnesses with 5,254 cases (5.1% of all patients) and the most-frequent cause of death (risk ratio versus all other illnesses 2.5:1). Animal exposures requiring rabies post-exposure prophylaxis increased from 0.7% (1998–2002) to 3.6% (2013–2018). The proportion of patients with seasonal influenza increased from zero in 1998–2002 to 0.9% in 2013–2018. There were 44 cases of viral haemorrhagic fever, most during the past five years. Arboviral infection numbers increased significantly as did the range of presenting arboviral diseases, dengue and chikungunya diagnoses increased by 2.6% and 1%, respectively. Interpretation Travel medicine must adapt to serve the changing profile of travellers, with an increase in migrants and persons visiting relatives and friends and the strong emergence of vector-borne diseases, with potential for further local transmission in Europe. Funding This project was supported by a cooperative agreement (U50CK00189) between the Centers for Disease Control and Prevention to the International Society of Travel Medicine (ISTM) and funding from the ISTM and the Public Health Agency of Canada.

Travel Med Infect Dis 2019; 33:101463. [PMID: 31376464 DOI: 10.1016/j.tmaid.2019.07.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2018] [Revised: 07/25/2019] [Accepted: 07/26/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND Millions of tourists visit Malaysia annually while a large number of Malaysians travel overseas. Taking care of travellers' healthcare needs is important aspect of the healthcare system. Community pharmacies are ideally positioned to provide travel health-related services. However, studies are lacking in this area. Therefore, this study aims to explore the nature and type of travel health-related services provided by Malaysian community pharmacies. METHODS A survey was carried out at 135 community pharmacies in nine districts of Selangor, Malaysia, from November 2017 to February 2018, using a self-administered standardized questionnaire. RESULTS The majority (n = 95, 85%) of community pharmacies reported to have provided services to both international travellers and outbound Malaysian travellers. The common healthcare services provided to international travellers were monitoring of chronic diseases including hypertension and diabetes, and advice on minor ailments, supplements and medical devices. The key health services provided to outbound Malaysian travellers were advice on vaccination requirements, better management of chronic diseases and necessary medications to manage illness during travel. Most of the respondents supported the provision of travel health-related services through the community pharmacies. CONCLUSION The study findings showed that Malaysian community pharmacies provided several travel health-related services to both international and Malaysian outbound travellers. Pharmacists in Malaysia are ideally positioned to have an increased role in travel medicine. They have the training to advise on complex medication issues especially with regard to interactions and polypharmacy. However, further training and courses should be provided that are tailored specifically for the needs of this professional group.

Melioidosis in travelers: An analysis of Dutch melioidosis registry data 1985-2018. Travel Med Infect Dis 2019; 32:101461. [PMID: 31369898 DOI: 10.1016/j.tmaid.2019.07.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Revised: 07/22/2019] [Accepted: 07/24/2019] [Indexed: 12/16/2022]
Abstract
BACKGROUND Melioidosis, caused by the Gram-negative bacterium Burkholderia pseudomallei, is an opportunistic infection across the tropics. Here, we provide a systematic overview of imported human cases in a non-endemic country over a 25-year period. METHODS All 55 Dutch microbiology laboratories were contacted in order to identify all B. pseudomallei positive cultures from 1990 to 2018. A response rate of 100% was achieved. Additionally, a systematic literature search was performed, medical-charts reviewed, and tissue/autopsy specimens were re-assessed. RESULTS Thirty-three travelers with melioidosis were identified: 70% male with a median-age of 54 years. Risk factors were present in most patients (n = 23, 70%), most notably diabetes (n = 8, 24%) and cystic fibrosis (n = 3, 9%). Countries of acquisition included Thailand, Brazil, Indonesia, Panama, and The Gambia. Disease manifestations included pneumonia, intra-abdominal abscesses, otitis externa, genitourinary, skin-, CNS-, and thyroid gland infections. Twelve (36%) patients developed sepsis and/or septic shock. Repeat episodes of active infection were observed in five (15%) and mortality in four (12%) patients. Post-mortem analysis showed extensive metastatic (micro)abscesses amongst other sites in the adrenal gland and bone marrow. CONCLUSIONS The number of imported melioidosis is likely to increase, given rising numbers of (immunocompromised) travelers, and increased vigilance of the condition. This first systematic retrospective surveillance study in a non-endemic melioidosis country shows that imported cases can serve as sentinels to provide information about disease activity in areas visited and inform pre-travel advice and post-travel clinical management.

Travel-related health events and their risk factors in HIV-infected sub-Saharan migrants living in France and visiting their native country: The ANRS VIHVO cohort study. Travel Med Infect Dis 2019; 29:40-47. [PMID: 30951905 DOI: 10.1016/j.tmaid.2019.03.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Revised: 02/20/2019] [Accepted: 03/28/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Literature on health events in HIV-infected travellers is scarce, particularly in sub-Saharan African (SSA) migrants. METHODS We investigated health events in HIV-infected SSA migrants living in France during and after travel to their native country. All had a pre-travel plasma viral load (pVL) below 200 copies/mL and were on stable combined antiretroviral therapy (cART). Logistic regression models were used to assess the risk factors for at least one adverse health event or febrile event. RESULTS Among 264 HIV migrants, pre-travel median CD4 count was 439/mm3 and 27 migrants (6%) experienced a low-level viremia between 50 and 200 copies/mL. One hundred (38%) experienced at least one event (13 experienced two events). The most common events were gastrointestinal, including diarrhoea (n = 29, 26%), respiratory events (n = 20, 18%), and malaria (n = 17, 15%; 1 death). In multivariable analysis, a pre-travel low-level viremia and a lack of pre-travel medical advice significantly increased the risk for any event (OR 4.31, 95% CI, 1.41-13.1; and OR 3.62, 95% CI, 1.38-9.47; respectively). A lack of pre-travel advice significantly increased the risk for febrile event. CONCLUSIONS Early and tailored counselling on pre-travel medical advice regarding diarrhoea and vector-borne diseases prophylactic measures in HIV-infected SSA migrants should be emphasised before travel to Africa.
