Abstract:

International tourist arrivals continue to increase over time due to global economic growth, increasing middle class in developing countries, technological advances, innovative business concepts, cost-effective travel, and facilitation of visas. The increase in tourist visits has resulted in health problems due to the trips. Respiratory tract infections are the main reason tourists seek medical care. Respiratory infections occur in 20% of all tourists, almost the same as the incidence of diarrhea. The majority of international inbound tourism involved air travel. Though physiological changes happen in everyone while air travel, people with lung disease are at high risk for significant complications and necessitate a specific risk assessment strategy. A pre-flight evaluation is conducted if there is any uncertainty regarding the patient's fitness for flight and the effect of eligibility to fly. This literature review summarized the important aspect of travel medicine from the respiratory medicine point of view.

Abstract:

SummaryAlthough long-distance air travel is commonly regarded as a risk factor for venous thromboembolism, the risk of clinically important events has not been well defined. We estimated the absolute risk of dying from pulmonary embolism following longdistance air travel in a national population-based descriptive study of 121 men and women who were aged 15–59 years (the age range in which the majority of international arrivals are found) and whose underlying cause of death was certified as codes 415.1, 451, or 453 of the International Classification of Diseases (ninth revision). Eleven cases had undertaken longdistance air travel in the four weeks before the onset of the fatal episode. The estimated risks of fatal pulmonary embolism following a flight of at least three hours’ duration were 0.5 (95% CI 0.2–1.2) and 0.6 (95% CI 0.2–1.4) per million arrivals for overseas visitors and New Zealand residents, respectively. For air travel of more than eight hours’ duration, the risk in New Zealand residents was 1.3 (95% CI 0.4–3.0) per million arrivals. We also conducteda case-control study based on those cases who were normally resident in New Zealand and registered on the electoral roll (n=99). For each case, four controls matched for sex, age, and electorate, were randomly selected from the electoral roll. In the key analysis (based on 88 cases and 334 controls), the adjusted odds ratio for travellers who had flown for more than eight hours was 7.9 (95% CI 1.1–55.1) compared with those who did not undertake a long-distance flight. Longdistance air travellers have a higher risk of dying from pulmonary embolism than non-travellers, but the absolute risk in people aged 15–59 years appears to be very small.

Abstract:

✓ In this report the authors discuss a patient who experienced symptoms of an acute right frontal, intraparenchymal pneumatocele while on an airplane descending to an international airport. This rare complication of an ethmoid sinus osteoma that eroded upward through the dura mater is described along with a literature review. A persistent headache and inappropriate behavior consistent with a frontal lobe syndrome brought the patient to clinical and imaging evaluation, which revealed a large right frontal lobe pneumatocele and an associated ethmoid sinus osteoma extending upward into the frontal lobe. Through a right frontal craniotomy, the air cavity was evacuated, the osteoma partially excised, and the dural defect closed using a vascularized pericranial flap. Postoperatively, the patient made an unremarkable recovery. For patients with air sinus osteomas extending into the cranial cavity, air travel or other barotrauma may result in a life-threatening tension pneumatocele.

Abstract:

Few studies have examined the link between air cargo and business travel, despite there being a generally accepted understanding that these two variables are inextricably related to each other. This paper examines the relationship between air cargo and business travel at the international level and analyses how these two variables are causally related. Moreover, we break down the sample into three major Australian states (New South Wales, Queensland, and Victoria), as each possesses a distinct flavour in trade and commerce. Utilising Granger causality methods, we have found evidence that there is a direct causal relationship between business travel and air cargo in the short run, and a bi-directional relationship in periods of 12 months and longer. The nature of the Granger causality at the state-level substantially differs from state to state, suggesting that the economic landscape of Australia’s local economy has a significant impact on the air cargo and business travel relationship.

Abstract:

The COVID-19 pandemic has reduced the amount of international travel, however, the speed and convenience of jet travel is unparalleled and our love of visiting far flung places at low cost will not have gone away for good. Now is an ideal time to review the health considerations of travelling in order to provide safe advice to our patients, who are increasingly elderly and travel with a wider range of medical co-morbidity. The purpose of this article is to consolidate guidance from the Civil Aviation Authority and the International Air Travel Association with supplementary travel information from other specialist organisations to help develop understanding of the issues air travel may pose for patients in primary care.

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.

Abstract:

China’s international air transportation has experienced tremendous growth and major reforms over the past two decades. While there has been a considerable discussion on the evolution of China’s domestic aviation market, studies on China’s international aviation markets have been limited. This paper first describes the historical development of China’s international aviation market and then, based on actual origin/destination (O/D) passenger flow data, explores the relevant evolution of China’s international air networks from the perspectives of the spatial distribution of international air networks and clustering characteristics of international air passengers. The development of China’s international aviation market can be attributable to the deregulation process in China’s aviation market and a broad “opening up” strategy in the global forum after 1990. Due to China’s proximity to East Asia and Southeast Asia, China’s international air networks show an obvious clustering pattern for short and medium-haul travel in Asia. In addition, average international air travel distance, institutional and policy changes, and increasing foreign trade and foreign tourism are crucial for the expansion of China’s international air networks.

Abstract:

Asthma is a very prevalent condition. A significant proportion of patients with asthma will engage in travel for work or leisure purposes. Patients may be fearful of travel, especially during the current COVID-19 global pandemic. However, there are health benefits to be obtained, including leaving an area of high air pollution and travelling to an area of lower air pollution, travelling to high altitude, the beneficial effects of a low trigger environment and the psychological benefits associated with travel. Travel can be associated with improved diet and increased vitamin D exposure. Caution should be taken with alcohol consumption as it may worsen asthma. Whilst bariatric surgery has been shown to improve asthma symptoms and control, there are dangers associated with bariatric surgery tourism that the traveller should be made aware of. Travellers with asthma may experience jet lag and a worsening in their symptoms. Caution is required around exogenous melatonin use. Optimal asthma control pre-travel is essential. The destination should be carefully considered, in terms of air pollution, altitude and possible environmental triggers. Pre-travel, written asthma management plans should be reviewed and updated if necessary. Patients should carry more asthma medications than they think is necessary, including oral corticosteroids and a pressurised metered dose inhaler via spacer. Travellers with asthma should have a self-management plan in the event of exacerbations occurring during travel.

Abstract:

In the present article we investigate the geography and magnitude of the climate footprint of long-distance travel with Brussels, Belgium, as a destination. The internationally networked position of this city goes hand in hand with a strong dependence on international mobility, which largely materializes in impressive volumes of long-distance travel and associated consumption of important amounts of fossil fuel. Despite a surge in concerns about global warming, the climate footprint of most international travel, notably air travel, is not included in the official national and regional climate inventories, or in other words, it is not territorialized. The official climate footprint of the Brussels-Capital Region attained 3.7 Mton CO<sub>2</sub>eq per year (in 2017). Based on our exploratory calculations, however, the total estimated climate footprint of all Brussels-bound international travel equalled an additional 2.7 Mton CO<sub>2</sub>eq. In terms of geographical distribution, over 70% of international travellers to Brussels come from Europe, while these represent only 15% of the climate footprint of all international travel to Brussels. We conclude that the practice of not allocating emissions caused by international travel to territorial units has kept the magnitude and complexity of this problem largely under the radar and contributes to the lack of societal support for curbing growth of international aviation.

Abstract:

Abstract While there is abundant evidence demonstrating that residents permanently migrate in search of locations with cleaner air, there are considerably fewer studies that investigate if travellers also take short-term trips to reduce their exposure to air pollution. In this study, we use a complete dataset of flights at Beijing International Airport to investigate if travel patterns are indeed correlated with air quality-differences across cities in China. Our identification strategy is aided by instrumenting air quality using thermal inversions. We find that a one-unit increase in the Air Pollution Index of origin over destination city would lead to a 0.36% increase in number of passengers on the flight. When considered separately by cabin-class, the number of first-class passengers increased about three-times faster than economy-class. Using lagged air quality information, we also find that averting-related travel decisions are most sensitive to destination’s air quality on day-of-travel. This indicates that flight passengers likely rely on air quality forecast information to make air pollution-induced travel decisions.

Abstract:

This article analyses the interdependency of demand for two of the leading traded services globally: international travel (transportation) and international tourism. Based on the Almost Ideal Demand System, the study models transport and tourism demand simultaneously for a range of countries: Australia, New Zealand, the United States and the United Kingdom. Overall, tourism demand is found to be more expenditure and price-elastic than is the demand for transport services to the same destination. The cross-price elasticities indicate significant interdependencies of demand between transport and tourism, and between destinations. Overall, the cross-price elasticities confirm the complementarity between transport demand and tourism demand. However, in the cases of the UK demand for the United States and the US demand for the United Kingdom, substitutability between the two demand types is found.

Abstract:

Relatively low travel costs and abundant opportunities for research funding in Switzerland and other developed countries allow researchers large amounts of international travel and collaborations, leading to a substantial carbon footprint. Increasing willingness to tackle this issue, in combination with the desire of many academic institutions to become carbon-neutral, calls for an in-depth understanding of academic air travel. In this study, we quantified and analyzed the carbon footprint of air travel by researchers from the École Polytechnique Fédérale de Lausanne (EPFL) from 2014 to 2016, which is responsible for about one third of EPFL’s total CO2 emissions. We find that the air travel impact of individual researchers is highly unequally distributed, with 10% of the EPFL researchers causing almost 60% of the total emissions from EPFL air travel. The travel footprint increases drastically with researcher seniority, increasing 10-fold from PhD students to professors. We found that simple measures such as restricting to economy class, replacing short trips by train and avoiding layovers already have the potential to reduce emissions by 36%. These findings can help academic institutions to implement travel policies which can mitigate the climate impact of their air travel.

Full text

Abstract:

Aviation has been hit hard by COVID-19, with passengers stranded in remote destinations, airlines filing for bankruptcy, and uncertain demand scenarios for the future. Travel bubbles are discussed as one possible solution, meaning countries which have successfully constrained the spread of COVID-19 gradually increase their mutual international flights, returning to a degree of normality. This study aims to answer the question of whether travel bubbles are indeed observable in flight data for the year 2020. We take the year 2019 as reference and then search for anomalies in countries’ flight bans and recoveries, which could possibly be explained by having successfully implemented a travel bubble. To the best of our knowledge, this study is the first to try to address the identification of COVID-19 travel bubbles in real data. Our methodology and findings lead to several important insights regarding policy making, problems associated with the concept of travel bubbles, and raise interesting avenues for future research.

Abstract:

Purpose:The current study examined the sleep, travel, and recovery responses of elite footballers during and after long-haul international air travel, with a further description of these responses over the ensuing competitive tour (including 2 matches).Methods:In an observational design, 15 elite male football players undertook 18 h of predominantly westward international air travel from the United Kingdom to South America (–4-h time-zone shift) for a 10-d tour. Objective sleep parameters, external and internal training loads, subjective player match performance, technical match data, and perceptual jet-lag and recovery measures were collected.Results:Significant differences were evident between outbound travel and recovery night 1 (night of arrival; P < .001) for sleep duration. Sleep efficiency was also significantly reduced during outbound travel compared with recovery nights 1 (P = .001) and 2 (P = .004). Furthermore, both match nights (5 and 10), showed significantly less sleep than nonmatch nights 2 to 4 and 7 to 9 (all P < .001). No significant differences were evident between baseline and any time point for all perceptual measures of jet-lag and recovery (P > .05), although large effects were evident for jet-lag on d 2 (2 d after arrival).Conclusions:Sleep duration is truncated during long-haul international travel with a 4-h time-zone delay and after night matches in elite footballers. However, this lost sleep appeared to have a limited effect on perceptual recovery, which may be explained by a westbound flight and a relatively small change in time zones, in addition to the significant increase in sleep duration on the night of arrival after the long-haul flight.

Abstract:

Epidemics of dengue fever occur every 3 to 4 years in the Philippines. The risk of a dengue fever outbreak in the Philippines has been heightened since Typhoon Haiyan struck the region in November 2013 because recovery efforts have been slow to progress. The structural damage caused by the typhoon resulted in an abundance of standing water, which can serve as mosquito breeding grounds. Should an outbreak of dengue occur, infected travelers departing the Philippines pose a risk because they may introduce the dengue virus into local vector populations (of Aedes aegypti and Aedes albopictus) at their destinations. This study quantifies the risk posed by potentially infected travelers departing the Philippines by using a network model that incorporates predictive species distribution models, demographic features of destination areas, and air traffic volumes. The analysis reveals that a majority of travelers departing Philippine airports deplane in regions suitable for harboring Aedes aegypti or Aedes albopictus; this factor increases the likelihood of further spread of the disease if an outbreak were to occur. Because it is impractical to implement all possible monitoring and control measures at all locations connected to the Philippines, this analysis ranks the set of candidates and thus allows surveillance resources to be optimally deployed.

Abstract:

Flying is the most important way of travelling in the continually growing international tourism. Number of passengers and those with preexisting diseases, mainly with cardiopulmonary problems, is increasing over years. One of the main tasks of the pre-travel advice is to assess tolerance to hypoxia of the traveler, and specify the necessity, as well as the type and volume of supplementary oxygen therapy. It is indispensable to know the cabin-environment and impact of that on the travelers’ health. Travel medicine specialist has to be aware of the examinations which provide information for the appropriate decision on the fit-to-fly condition of the patient. The physician who prepares the patient with chronic obstructive pulmonary disease for repatriation by regular flight and the escorting doctor have to be fully aware of the possibilities, modalities, advantages and contraindications of the on-board oxygen supply and therapy. In this review, the authors give a summary of literature data, outline the tools of in-flight oxygen therapy as well as discuss possibilities for the preflight assessment of patients’ condition including blood gas parameters required for safe air travel, as recommended in international medical literature. The preparation process for repatriation of patients with chronic obstructive pulmonary disease is also discussed. Orv. Hetil., 2013, 154, 323–337.

Abstract:

This study examines long term forecasting of international air travel demand in Nigeria. Yearly data from 2001 to 2017 were collected from secondary sources. Ordinary Least Square (OLS) regression was used to forecast the ten years (2018 to 2028) demand for international air passenger travel in Nigeria. The demand for international air passenger in Nigeria from year 2001 to 2017 was compared with the forecast. Calculation reveals that the coefficient of determination R2 is 0.815, while the computed reveals that the coefficient of determination R2 is 0.769, this difference can be attributed to approximations to two decimal places for calculated test. The calculated test and computed test reveals that the error term is minimal and the explanation level is high; hence the prediction or forecast is reliable. The forecast for years 2020, 2025 and 2028 are 5,282,453, 6,342,519, and 6,978,559 respectively which are about 48 percent increase, 78 percent increase, and 95 percent increase respectively from demand in year 2017. The forecast of ten years from year 2018 to year 2028 reveals that there will be more increase in the demand for international air passenger travel in Nigeria. The implication of this increment is that existing air transport infrastructures should be upgraded, and new infrastructures should be procured and installed; airport and airline operations should be reviewed and strategized such that they will meet the expectations of airline and airport users. Other concerned business stakeholders should use this data to plan and invest as there is high tendency for profit making.

Abstract:

Given the importance of the air traffic analysis both for airlines and civil aviation authorities, the main aim of this paper is to develop an econometric model to analyze, assess and forecast the air travel demand in Morocco. To select the relevant variables, the all possible regression procedure was conducted. The model containing price index consumer, the gross national product, household final consumption per capita and international tourist’s arrivals is the most appropriate model to represent the demand for air travel in Morocco.

Abstract:

Practical relevance: More cats are travelling by air every year; however, air travel involves several common causes of stress for cats, such as environmental changes and a lack of control and predictability. The use of a multimodal stress management protocol for all stages of the relocation process, including appropriate and effective anxiolytic medication where necessary, is therefore important in order to safeguard the cat’s welfare while travelling. Clinical challenges: Cats may be presented to veterinarians for the purpose of preparing them and/or their documentation for air travel. Maintaining and protecting a cat’s physical, mental and emotional health in a stressful environment, while subjected to likely unfamiliar sights, noises, smells and the movement of the aircraft, and additionally dealing with international legislation, regulations and documents, can pose a complex challenge to veterinarians. Aims: This review describes the importance of stress management during air travel for cats, aims to raise awareness about the often poorly understood challenges involved, and outlines effective and airline-compliant stress management modalities. While the discussion is focused on air travel specifically, the stress management methods described can be applied to all types of longer distance travel, such as a long road trip or a ferry crossing, as well as a stay in a holiday home. Evidence base: There are currently no studies specifically on air travel in cats and, similarly, there are also limited data on air travel in other species. Many of the recommendations made in this review are therefore based on the authors’ extensive experience of preparing pets for travel, supported by published data when available.

Abstract:

The current study examined the effects of 10-h northbound air travel across 1 time zone on sleep quantity, together with subjective jet lag and wellness ratings, in 16 male professional Australian football (soccer) players. Player wellness was measured throughout the week before (home training week) and the week of (away travel week) travel from Australia to Japan for a preseason tour. Sleep quantity and subjective jet lag were measured 2 d before (Pre 1 and 2), the day of, and for 5 d after travel (Post 1–5). Sleep duration was significantly reduced during the night before travel (Pre 1; 4.9 [4.2−5.6] h) and night of competition (Post 2; 4.2 [3.7−4.7] h) compared with every other night (P < .01, d > 0.90). Moreover, compared with the day before travel, subjective jet lag was significantly greater for the 5 d after travel (P < .05, d > 0.90), and player wellness was significantly lower 1 d postmatch (Post 3) than at all other time points (P < .05, d > 0.90). Results from the current study suggest that sleep disruption, as a result of an early travel departure time (8 PM) and evening match (7:30 PM), and fatigue induced by competition had a greater effect on wellness ratings than long-haul air travel with a minimal time-zone change. Furthermore, subjective jet lag may have been misinterpreted as fatigue from sleep disruption and competition, especially by the less experienced players. Therefore, northbound air travel across 1 time zone from Australia to Asia appears to have negligible effects on player preparedness for subsequent training and competition.

Abstract:

In an attempt to meet desires and needs of the patients with pulmonary diseases who plan to travel by air craft, physicians might face complex problems. They are expected to estimate individual risk and need of oxygen supplementation that might be necessary. Sometimes, these patients are a source of infection to other passengers. Some international air travel guidelines offer precise and mandatory conditions, which should be fulfilled during the flight in case such a patient has to travel. Thus, patients with drug resistant tuberculosis are not permitted to travel at all, while all the other patients with pulmonary tuberculosis and other air born infections should not travel during the infectious period. Recent or uncured pneumothorax and hemoptisis are contraindications for travelling. Other patients with pulmonary diseases, especially those with manifested respiratory insufficiency should respect the rules, which include contacting air travel company prior to flight, sharing information about their health condition and asking for details on possibilities of oxygen supplementation while on board, currence voltage, and availability of plugs in the cabin where the devices for respiratory support might be put in, etc. A possibility of hypoxia during the flight is an important individual risk. Methods of hypoxia prediction and possibilities of oxygen supplementation in air craft cabin are in focus of current research.

Abstract:

Abstract Climate change is regarded as a global scale process in which an increase of magnitude and intensity of severe weather events is observed, thus affecting both air travel as well as airport infrastructure. Although the COVID-19 crisis has a significant negative impact on air travel and thus on the further development of airport infrastructure, the demand for air travel will continue to rise as the crisis nears the end. The aim of this paper is to analyse and highlight the climate change associated hazards for the airport infrastructure as well as for the safety of passengers and goods in the Western part of Romania, mainly Traian Vuia International Airport from Timişoara. Throughout this analysis, aviation related severe weather events, such as thunderstorms, hail events, fog, icing, squalls, low level wind shear, snow falls and heavy precipitation, which affect airport infrastructure and thus air travel, are highlighted. By analysing meteorological parameters from the time scale 1980-2010 together with climate change scenarios, and thus developing weather hazard maps, a better perspective of area-related hazards and therefore customized mitigation measures and adaptation strategies are to be developed. The implementation of modern forecasting equipment such as dual polarization Terminal Doppler Weather Radar (TDWR) is thus necessary in order to prevent loss of human lives, to reduce financial losses and to protect the airport infrastructure and the aeronautical navigation and communication facilities. Long term changes in meteorological parameters include an increase in air temperature, an increase in speed for both horizontal and vertical windshear during severe weather events, an increasing number of air mass thunderstorms and an increase of situations with limited visibility especially during the late autumn and early spring time.

Abstract:

This study examines international air travellers' attitudes and perceptions of the importance of food safety, sources of information on food safety, and the value of a global grading system for food service establishments. A survey questionnaire was used to gather data from travellers at Changi International Airport, Singapore. Results indicated an increase in the reported incidence of food-borne illness occurring with increased frequency of travel. Friends who had travelled to the destination were considered the best source of food safety information. Travel plans were altered out of concern about food safety and the food safety reputation of the destination. Eighty per cent of respondents stated that they would benefit from a standardized food safety grading system for the world's eating establishments.

Abstract:

The number of travel-acquired dengue infections has been on a constant rise in the United States and Europe over the past decade. An increased volume of international passenger air traffic originating from regions with endemic dengue contributes to the increasing number of dengue cases. This paper reports results from a network-based regression model which uses international passenger travel volumes, travel distances, predictive species distribution models (for the vector species), and infection data to quantify the relative risk of importing travel-acquired dengue infections into the US and Europe from dengue-endemic regions. Given the necessary data, this model can be used to identify optimal locations (origin cities, destination airports, etc.) for dengue surveillance. The model can be extended to other geographical regions and vector-borne diseases, as well as other network-based processes.

Abstract:

The COVID-19 pandemic has caused an ongoing tourism crisis. The most significant threat to the global economy since the Second World War is the product of unparalleled global travel constraints and residency orders. Tourism is particularly vulnerable to intervention to fight pandemics due to limited movement and social distance. Global markets, including tourist services such as world travel, domestic tourism, day trips, and parts as varied as air, cruises, transport, hotels, cafes and restaurants, conferences, festivals, meetings, or sports activities have automatically been affected by international, regional, and local travel restrictions. Leading to the dramatic stagnation of global air traffic and the fact that many countries have placed travel restrictions, closed borders, or initiated quarantine times, international and domestic tourism has reduced dramatically. Several countries have failed to return tourists home, with hundreds of thousands of people in all areas of the world participating in vital outbound markets. This study contributes to the tourism and hotel industry, particularly from an economic perspective, by reviewing related research, reports, and working papers.
