RESUMO

OBJECTIVE: The current pandemic makes the international flights facing multiple challenges including infection during flights. Here the objective is to analyze the infection trend of flights from a regional data set and discuss the solutions for diagnosis and travel medicine. MATERIALS AND METHODS: The public data was applied for trend analysis and new solutions were provided based on the current diagnosis information and resembling cancer diagnosis. RESULTS: Flights infection has decreased since the large-scale cease of flights. Challenges of prevention of SARS-CoV-2 infection in flights exist due to testing accuracy, asymptomatic and many other factors including people gathering. To avoid the pandemic worsen, the solutions are provided for new coming flight resumes. Hotel, mandatory PPE, airport diagnosis, rapid imaging/biomarker diagnosis by advanced high-technology and emergency-travel medicine department are suggested as solutions. CONCLUSIONS: SARS-CoV-2 prevention in flights needs multiple solutions by potential on-site diagnosis and urgent establishment of a travel medicine unit at airport.

RESUMO

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.).

RESUMO

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.

RESUMO

Yellow fever is still a current threat? Yellow fever is a mosquito-borne disease. Africa is the major endemic zone, although there have been epidemics of concern in South America in the last 3 years, especially in Brazil. The virus causes a febrile hepatitis, which can lead to hemorrhagic complications and death. Diagnosis is based on non-specific serological tests. There is no curative treatment. Prevention relies on protection against mosquito bites and on vaccination with a live attenuated vaccine. WHO recommends only one dose of vaccine but data from the literature about life-long protection are divergent on that point, and travel medicine French authorities still recommend a second dose in most at-risk situations.

RESUMO

Dengue fever: an emerging infectious disease. Dengue fever is caused by an arbovirus of the family Flaviviridae and the genus Flavivirus, of which there are 4 serotypes (DEN-1, DEN-2, DEN-3, DEN-4). It is transmitted by the bite of a diurnal mosquito of the genus Aedes, mainly A. aegypti and A. albopictus. An increasing cause of acute fever in travellers, it threatens to emerge in temperate regions where competent mosquitoes (Aedes) are established. Dengue fever is characterized by its clinical polymorphism ranging from asymptomatic to severe forms, which are rare in travellers. Its definite diagnosis is based on virological tests selected according to the stage of the disease and the kinetics of the virus. Its treatment is only symptomatic. It is a notifiable disease in mainland France and is subject to a plan to combat its spread and to specific surveillance in the overseas departments. Dengue prevention is based on the application of personal anti-vectorial protection measures among travellers, awareness-raising among health professionals and social mobilization to combat larval gites in endemic regions or regions colonized by Aedes. In France, the tetravalent vaccine Dengvaxia, which is licensed in France, is not recommended for people residing in overseas departments and for travelers to endemic areas.

RESUMO

The emergence and international spread of SARS-CoV-2 led to unprecedented challenges for international travelers including health-related concerns and international travel restrictions. Remarkably, overseas travelers consulted at our travel clinic during the first quarter of 2020 were apparently not disconcerted by the evolving pandemic with a continuously high rate of consultations at our center; 85% of travelers did not actively inquire about COVID-19 during the pretravel consultation including individuals with clinically significant immunosuppression constituting a high-risk group for COVID-19-related adverse health outcome. This experience demonstrates the societal responsibility of travel medicine practitioners to proactively provide unbiased information about the health-related and travel-related impact of newly emerging infections.

RESUMO

On February 5 the Japanese government ordered the passengers and crew on the Diamond Princess to start a two week quarantine after a former passenger tested positive for COVID-19. During the quarantine the virus spread rapidly throughout the ship. By February 20, there were 651 cases. We model this quarantine with a SEIR model including asymptomatic infections with differentiated shipboard roles for crew and passengers. The study includes the derivation of the basic reproduction number and simulation studies showing the effect of quarantine with COVID-19 or influenza on the total infection numbers. We show that quarantine on a ship with COVID-19 will lead to significant disease spread if asymptomatic infections are not identified. However, if the majority of the crew and passengers are immune or vaccinated to COVID-19, then quarantine would slow the spread. We also show that a disease similar to influenza, even with a ship with a fully susceptible crew and passengers, could be contained through quarantine measures.

RESUMO

BACKGROUND: Before the impact of the coronavirus disease 2019 pandemic, cruise travel had experienced exponential growth in the preceding decade. Travel medicine practitioners were increasingly called upon to provide pre-cruise travel advice and medical clearance. Demand for these services will return at some time in the future. METHODS: The clinical conditions seen in those presenting for care on six small-vessel scientific cruises to Antarctica were analysed. RESULTS: Personnel presented on 196 occasions resulting in 257 consultations (when initial plus all follow-up consultations were included). Personnel presented with a clinical condition at a rate of 17.9 per 1000 person-days at sea. The total consultation rate was 23.5 per 1000 person-days at sea. Injury accounted for 24% of all presentations at a rate of 4.3 per 1000 person-days at sea. Dermatological, soft tissue and musculoskeletal, general malaise and motion sickness were the four most common presentations. CONCLUSIONS: Pre-cruise advice for travellers planning small-vessel cruises to polar regions needs to include skin care, prevention and management of sea sickness and how to reduce the risk of injury. Those providing medical care on such cruises should be prepared to manage a wide range of clinical presentations.

RESUMO

BACKGROUND: Substantial limitations have been imposed on passenger air travel to reduce transmission of severe acute respiratory syndrome coronavirus 2 between regions and countries. However, as case numbers decrease, air travel will gradually resume. We considered a future scenario in which case numbers are low and air travel returns to normal. Under that scenario, there will be a risk of outbreaks in locations worldwide due to imported cases. We estimated the risk of different locations acting as sources of future coronavirus disease 2019 outbreaks elsewhere. METHODS: We use modelled global air travel data and population density estimates from locations worldwide to analyse the risk that 1364 airports are sources of future coronavirus disease 2019 outbreaks. We use a probabilistic, branching-process-based approach that considers the volume of air travelers between airports and the reproduction number at each location, accounting for local population density. RESULTS: Under the scenario we model, we identify airports in East Asia as having the highest risk of acting as sources of future outbreaks. Moreover, we investigate the locations most likely to cause outbreaks due to air travel in regions that are large and potentially vulnerable to outbreaks: India, Brazil and Africa. We find that outbreaks in India and Brazil are most likely to be seeded by individuals travelling from within those regions. We find that this is also true for less vulnerable regions, such as the United States, Europe and China. However, outbreaks in Africa due to imported cases are instead most likely to be initiated by passengers travelling from outside the continent. CONCLUSIONS: Variation in flight volumes and destination population densities creates a non-uniform distribution of the risk that different airports pose of acting as the source of an outbreak. Accurate quantification of the spatial distribution of outbreak risk can therefore facilitate optimal allocation of resources for effective targeting of public health interventions.

RESUMO

In the early stages of the 2019 novel coronavirus disease (COVID-19) pandemic, containment of disease importation from epidemic areas was essential for outbreak control. This study is based on publicly accessible data on confirmed COVID-19 cases in Taiwan extracted from the Taiwan Centers for Disease Control website. We analysed the characteristics, infection source, symptom presentation, and route of identification of the 321 imported cases that were identified from 21 January to 6 April 2020. They were mostly returned Taiwanese citizens who had travelled to one or more of 37 countries for tourism, business, work, or study. Half of these cases developed symptoms before arrival, most of the remainder developed symptoms 1-13 days (mean 4.0 days) after arrival, and 3.4% never developed symptoms. Three-quarters of the cases had respiratory symptoms, 44.9% had fever, 13.1% lost smell or taste, and 7.2% had diarrhoea. Body temperature and symptom screening at airports identified 32.7% of the cases. Of the remainder, 27.7% were identified during home quarantining, 16.2% were identified via contact tracing, and 23.4% were reported by hospitals. Under the strict enforcement of these measures, the incidence of locally acquired COVID-19 cases in Taiwan remains sporadic. In conclusion, proactive border control measures are effective for preventing community transmission of this disease.

RESUMO

Sea bathing is often a priority activity for travelers, with widely recognized health benefits. The dangers, in contrast, are underestimated, especially in tropical seas. We describe the scope of marine envenoming, trauma, and infections, representing 1-3 % of tropical and travel medicine consultations in the literature. Our review includes the eco-epidemiology, clinical approach, and prevention of envenoming by invertebrates (jellyfish, anemone, sea-urchin, starfish, octopus, sea cone) and some vertebrates (stingrays, stone fish, snakes). We include penetrating trauma (by stingray, stonefish, sea urchin, coral) and infections (mycobacteria, marine bacteria). Eating-related dangers (ciguatera, fugu, parasites) are not described here. We also present antidotes, antivenoms, and first-aid.

RESUMO

When considering women's health during travels, it is mainly pregnant women who are concerned. Indeed, because of the physiological changes, they are more vulnerable to infectious and non-infectious diseases related to the trip itself or to specific activities. This article lists the essential risks for pregnant women travelling in tropical countries and provides specific recommendations, so that the general practitioner is better able to advise this vulnerable population. If the trip is suitable and in the absence of any pre-existing complication, travelling during pregnancy is not contraindicated.
