BACKGROUND: International travel can expose travellers to pathogens not commonly found in their countries of residence, like dengue virus. Travellers and the clinicians who advise and treat them have unique needs for understanding the geographic extent of risk for dengue. Specifically, they should assess the need for prevention measures before travel and ensure appropriate treatment of illness post-travel. Previous dengue-risk maps published in the Centers for Disease Control and Prevention's Yellow Book lacked specificity, as there was a binary (risk, no risk) classification. We developed a process to compile evidence, evaluate it and apply more informative risk classifications. METHODS: We collected more than 839 observations from official reports, ProMED reports and published scientific research for the period 2005-2014. We classified each location as frequent/continuous risk if there was evidence of more than 10 dengue cases in at least three of the previous 10 years. For locations that did not fit this criterion, we classified locations as sporadic/uncertain risk if the location had evidence of at least one locally acquired dengue case during the last 10 years. We used expert opinion in limited instances to augment available data in areas where data were sparse. RESULTS: Initial categorizations classified 134 areas as frequent/continuous and 140 areas as sporadic/uncertain. CDC subject matter experts reviewed all initial frequent/continuous and sporadic/uncertain categorizations and the previously uncategorized areas. From this review, most categorizations stayed the same; however, 11 categorizations changed from the initial determinations. CONCLUSIONS: These new risk classifications enable detailed consideration of dengue risk, with clearer meaning and a direct link to the evidence that supports the specific classification. Since many infectious diseases have dynamic risk, strong geographical heterogeneities and varying data quality and availability, using this approach for other diseases can improve the accuracy, clarity and transparency of risk communication.

BACKGROUND: The Scorpaenidae are a large family of venomous marine fish that include scorpionfish, lionfish, and stonefish. Although most stonefish are confined to the Indo-Pacific, scorpionfish are distributed in the tropics worldwide, and two species of Indo-Pacific lionfish were inadvertently introduced into the Eastern Atlantic in the 1990s. Since then, lionfish have invaded shallow reef systems in the Eastern Atlantic, Gulf of Mexico, and Caribbean Sea. All of these regions are popular travel destinations for beachcombing, fishing, swimming, and scuba diving-recreational activities that increase risks of Scorpaenidae envenomation. METHODS: To meet the objectives of describing species-specific presenting clinical manifestations, diagnostic and treatment strategies, and outcomes of Scorpaenidae envenomation in travelers, Internet search engines were queried with the key words. RESULTS: Well-conducted, retrospective epidemiological investigations of Scorpaenidae envenomation case series concluded: (1) most cases occurred in young adult male vacationers visiting endemic regions; (2) victims sought medical attention for pain control within 2 hours of injury and presented with intense pain, edema, and erythema in affected extremities; (3) systemic manifestations and surgical interventions were relatively uncommon following initial management with hot water soaks and parenteral analgesics; (4) all cases required tetanus prophylaxis; deeply penetrating, lacerated, and necrotic wounds required antibiotic prophylaxis; and (5) equine Fab stonefish antivenom does have antigen-neutralizing cross-reactivities with both Indo-Pacific and Atlantic Scorpaenidae species and is indicated in severe scorpionfish and stonefish envenomation worldwide. CONCLUSIONS: Travel medicine practitioners should counsel their patients about Scorpaenidae envenomation risks in endemic regions and maintain a high index of suspicion regarding Scorpaenidae envenomation in all travelers returning from tropical beach and ocean holidays and reporting painful fish sting injuries.

BACKGROUND: Malaria prophylaxis recommendations issued by different health authorities in Europe are inhomogeneous, and so is the opinion of experts, but a general trend towards reducing its use is evident, and prescribers apparently adhere more easily to more restrictive recommendations. METHODS AND RESULTS: A new Italian guideline has been produced, looking both at scientific evidence (data on malaria risk and drugs' side effects) and at the opinion of experts (surveys and previously issued recommendations). CONCLUSIONS: Collecting data on imported malaria, stating a clear methodology and introduce a discussion at international level should be the next goals in order to homogenise recommendations for malaria prophylaxis in Europe.

With an increasing number of children traveling internationally, there has been growing interest in studying the burden of travel-associated illnesses in children. We reviewed recently published (2007-2012) studies on travel-associated illness in children, and extracted the reported spectrum of dermatological conditions in children. Dermatologic problems are among the leading health concerns affecting children during and after return from international travel. Most are mild and self-limited, but an extended spectrum of conditions has been reported from a large retrospective multicenter study. Children may be especially at risk for infections related to environmental exposures, arthropod-related problems, and animal bites. Of note are also tropical and cosmopolitan systemic infections with potential for transmission in the receiving communities. Implications for pre- and post-travel care of children are emphasized.

BACKGROUND: Rabies, which is globally endemic, poses a risk to international travelers. To improve recommendations for travelers, we assessed the global availability of rabies vaccine (RV) and rabies immune globulin (RIG). METHODS: We conducted a 20-question online survey, in English, Spanish, and French, distributed via e-mail to travel medicine providers and other clinicians worldwide from February 1 to March 30, 2011. Results were compiled according to the region. RESULTS: Among total respondents, only 190 indicated that they provided traveler postexposure care. Most responses came from North America (38%), Western Europe (19%), Australia and South and West Pacific Islands (11%), East and Southeast Asia (8%), and Southern Africa (6%). Approximately one third of 187 respondents stated that patients presented with wounds from an animal exposure that were seldom or never adequately cleansed. RIG was often or always accessible for 100% (n = 5) of respondents in the Middle East and North Africa; 94% (n = 17) in Australia and South and West Pacific Islands; 20% (n = 1) in Tropical South America; and 56% (n = 5) in Eastern Europe and Northern Asia. Ninety-one percent (n = 158) of all respondents reported that RV was often or always accessible. For all regions, 35% (n = 58) and 26% (n = 43) of respondents felt that the cost was too high for RIG and RV, respectively. CONCLUSION: The availability of RV and RIG varied by geographic region. All travelers should be informed that RIG and RV might not be readily available at their destination and that travel health and medical evacuation insurance should be considered prior to departure. Travelers should be educated to avoid animal exposures; to clean all animal bites, licks, and scratches thoroughly with soap and water; and to seek medical care immediately, even if overseas.

A significant number of travellers sustain travel-related injury or illness, despite receiving pretravel advice. This appears to be due to a combination of inconsistent guidance about risks and recommendations, and partial adherence. This article considers perceptions and attitudes to risk, factors affecting uptake of advice, and features of an effective consultation. A framework is proposed for a pretravel consultation, using a shared decision-making approach. Engaging the traveller as an active participant in maintaining their own health and providing balanced, evidence-based information about risks and benefits is predicted to enhance the effectiveness of the pretravel consultation.

Risk assessment and risk management are fundamental to travel health consultations. Undertaking a comprehensive risk assessment involves gathering information on the traveller and their proposed journey. This information, as well as identifying specific travel-related hazards, should ensure risk-management advice and strategies are appropriate for individuals. This article outlines the principles of risk assessment and risk management in the context of travel health consultations.

In north Queensland, recurring epidemics of dengue fever are a public health concern. Each epidemic is initiated by an index case: an infected person arriving from an endemic country or region with dengue activity who then transmits the disease to local mosquitoes. A timely diagnosis of dengue in an index case and notification to public health services is essential to prevent epidemics. This qualitative study explores north Queensland general practitioners' experiences and patterns of treatment of febrile travellers. Individual, semi-structured interviews with 50 general practitioners working in north Queensland were conducted. Analysis of the data resulted in four themes for discussion: characteristics of febrile travellers presenting to local general practitioners, the cost of pathology tests as a barrier to diagnosis, appropriate pathology testing, and notifying tropical public health services. Recommendations from this study point to a need for ongoing education and training for general practitioners in best practice with regards pathology testing for suspected dengue fever cases. As well, there is a need to provide clearer guidelines to general practitioners on when to notify tropical public health services of suspicious diagnoses of dengue.

BACKGROUND: In travel medicine, as in other specialties, independent prescribing of medication has traditionally been the domain of practitioners like physicians, dentists, and midwives. However, a 2011 ruling in the Netherlands expands independent prescribing and introduces supplementary prescribing by nurses, with expected implementation over the next few years. As specialist nurses will not be eligible for independent prescribing, this study addresses supplementary prescribing, specifically by travel health nurses. Such nurses will work in partnership with an independent prescriber, usually a physician. After the physician evaluates a patient's condition and needs, the nurse may prescribe from an open or limited formulary. This supplementary approach seems appropriate in travel medicine, which is highly protocolized. A questionnaire survey was conducted to assess whether travel health nurses themselves aspire and feel competent to prescribe, and what training they might need. METHODS: All travel health nurses in the Netherlands received a questionnaire seeking their anonymous response. RESULTS: The response rate was 58%. Self-reported compliance with protocols and quality criteria was high; 82% of respondents aspire to prescribe and 77% feel competent to prescribe. Of the latter, 22% indicated that ongoing access to a doctor would remain important, and 14% preferred to prescribe under certain conditions like a restricted number of medicines. The reason most frequently given for not feeling competent was the need for additional education before obtaining prescribing rights (40%). Aspiration to prescribe was the only significant predictor for feeling competent to prescribe (odds ratios: 6.8; 95% confidence intervals: 3.5-13). Of all the responding nurses, 95% reported one or more educational needs related to prescribing, particularly in pharmacology. CONCLUSIONS: Most Dutch travel health nurses aspire to prescribe and feel competent for the supplementary approach, but require further education before the approach is implemented in travel medicine.
