“…6 In addition to CHIKV, the four dengue viruses (DENV [1][2][3][4] are endemic in the DR and also result in acute febrile illness in infected individuals. [7][8][9] DENVs are flaviviruses that are transmitted by the same mosquito vectors as CHIKV. Historically, dengue has been the leading cause of acute febrile illness among travelers returning from the Caribbean 7,8 ; therefore, risk for infection with both CHIKV and DENV now exists in the DR.…”

Abstract. Chikungunya spread throughout the Dominican Republic (DR) after the first identified laboratoryconfirmed cases were reported in April 2014. In June 2014, a U.S.-based service organization operating in the DR reported chikungunya-like illnesses among several staff. We assessed the incidence of chikungunya virus (CHIKV) and dengue virus (DENV) infection and illnesses and evaluated adherence to mosquito avoidance measures among volunteers/staff deployed in the DR who returned to the United States during July-August 2014. Investigation participants completed a questionnaire that collected information on demographics, medical history, self-reported illnesses, and mosquito exposures and avoidance behaviors and provided serum for CHIKV and DENV diagnostic testing by reverse transcription polymerase chain reaction and IgM enzyme-linked immunosorbent assay. Of 102 participants, 42 (41%) had evidence of recent CHIKV infection and two (2%) had evidence of recent DENV infection. Of the 41 participants with evidence of recent CHIKV infection only, 39 (95%) reported fever, 37 (90%) reported rash, and 37 (90%) reported joint pain during their assignment. All attended the organization's health trainings, and 89 (87%) sought a pretravel health consultation. Most (∼95%) used insect repellent; however, only 30% applied it multiple times daily and < 5% stayed in housing with window/door screens. In sum, CHIKV infections were common among these volunteers during the 2014 chikungunya epidemic in the DR. Despite high levels of preparation, reported adherence to mosquito avoidance measures were inconsistent. Clinicians should discuss chikungunya with travelers visiting areas with ongoing CHIKV outbreaks and should consider chikungunya when diagnosing febrile illnesses in travelers returning from affected areas.

“…Typically, studies track specific spatio-temporal disease, illness and injury vectors that commonly affect tourist populations (e.g., Chen, Chang, & Chen, 2014; Leshem et al, 2016; Ratnam, Leder, Black, & Torresi, 2013), and discuss associated pathological concerns (e.g., Flores, Hickey, Fields, & Ottolini, 2015; Matteelli, Centis, Sulis, & Tadolini, 2016; Salazar-Austin et al, 2015). Comprehensive statistical data about tourists’ use of health care abroad and their health outcomes is, however, mostly sparse and dated (Angelo, Kozarsky, Ryan, Chen, & Sotir, 2017).…”

Purpose: Despite established knowledge that tourists often fall ill or are injured abroad, little is known about their treatment. The intent of this study was to explore health care professionals’ treatment provision experiences on Cozumel Island, Mexico. Methods: 13 semi-structured interviews were undertaken with professionals across a number of health care vocations on Cozumel Island. Interviews were transcribed and thematically analysed to determine common challenges faced in the provision of treatment for transnational tourists. Results: Three thematic challenges emerged from the data: human and physical resource deficiencies, medical (mis)perceptions held by patients and complexities surrounding remuneration of care. Health care providers employ unique strategies to mitigate these challenges. Conclusion: Although many of these challenges exist within other touristic and peripheral spaces, we suggest that the challenges experienced by Cozumel Island’s health care professionals, and their mitigation strategies, exist as part of a complex entanglement between the island’s health care sector and its dominant tourism landscape. We call on tangential tourism services to take a larger role in ensuring the ease of access to, and provision of quality health care services for tourists on Cozumel Island.

“…In the USA, an upward trend in hospitalizations for dengue has been observed [73]. Ratnam and colleagues have recently reviewed dengue and international travel [74]. In a study on Australian travelers, seroconversion to dengue occurred in 1.0 %, an estimated incidence of 3.4 infections per 10,000 days of travel in this cohort; travel to India and China were implicated and all cases were subclinical [75].…”

Dengue: Update on Epidemiology

The epidemiology of dengue fever has undergone major shifts in recent decades. The global distribution has expanded to include more geographic areas. The intensity of transmission and the severity of infections have increased in areas where infection was already endemic. Multiple studies provide a clearer picture of the epidemiology and allow mapping of its distribution and change over time. Despite major efforts to control transmission, competent vectors now infest most tropical and subtropical regions; Aedes albopictus, also a competent vector, is able to survive in temperate areas, placing parts of Europe and North America at risk for local transmission. Many research teams in dengue-endemic areas are working to identify key local weather, vector, and other variables that would allow prediction of a likely epidemic early enough to permit interventions to avert it or blunt its impact.
