- Background Traveling to highly endemic areas for hepatitis A is increasing while the immunization level in travelers has been shown to be low in the countries studied. Methods In this population-based study, we have estimated the incidence rate of travel-related hepatitis A during 1997 to 2005 by use of the Swedish notification system of communicable diseases and an ongoing national database on travel patterns. We have also acquired airport-based immunization data from 2007. Results During the study period, 636 cases of travel-related hepatitis A were notified. Traveling to East Africa was associated with the highest incidence rate (14.1 cases/100,000 person months), followed by the Middle East (5.8/100,000 person months), and India with neighboring countries (5.6/100,000 person months). Visiting Friends and Relatives (VFR) travelers represented 83, 91, and 70% of the cases to these three regions. By age-group, the highest incidence was found in children 0 to 14 years (3.1/100,000 travelers) where 88% of the cases were VFR travelers. Incidence rate in unprotected travelers to East Asia, North Africa, and the Middle East was 2, 12, and 18 cases/100,000 person months, respectively. In 2007, 79% of the travelers were immunized against hepatitis A. Conclusions We conclude that travelers, and especially children, who are VFR in endemic areas constitute a high-risk group for acquiring hepatitis A infection, while the risk for unprotected tourists to East Asia is low.

- BACKGROUND: Influenza is a common vaccine-preventable disease among international travelers, but few data exist to guide use of reciprocal hemisphere or out-of-season vaccines. METHODS: We analyzed records of ill-returned travelers in the GeoSentinel Surveillance Network to determine latitudinal travel patterns in those who acquired influenza abroad. RESULTS: Among 37,542 ill-returned travelers analyzed, 59 were diagnosed with influenza A and 11 with influenza B. Half of travelers from temperate regions to the tropics departed outside influenza season. Twelve travelers crossed hemispheres from one temperate region to another, five during influenza season. Ten of 12 travelers (83%) with influenza who crossed hemispheres were managed as inpatients. Proportionate morbidity estimates for influenza A acquisition were highest for travel to the East-Southeast Asian influenza circulation network with 6.13 (95% CI 4.5-8.2) cases per 1000 ill-returned travelers, a sevenfold increased proportionate morbidity compared to travel outside the network. CONCLUSIONS: Alternate hemisphere and out-of-season influenza vaccine availability may benefit a small proportion of travelers. Proportionate morbidity estimates by region of travel can inform pre-travel consultation and emphasize the ease of acquisition of infections such as influenza during travel.

- BACKGROUND: Over the past decade, visitors to Alaska have spent increasing amounts of time engaged in water-based recreational activities aboard vessels of various sizes. Serious vessel-related injuries to travelers in Alaska involve not only medical care from unfamiliar health care providers and facilities but also entail the loss of vacation time and the need for injured travelers to return to their homes under less than optimal traveling conditions. METHODS: This study employed a retrospective, case-comparison analysis to identify differences in factors associated with recreational injuries acquired aboard watercraft that resulted in hospitalizations of residents and nonresidents of Alaska during 1991 to 2000. Tests of proportions were conducted to elucidate differences in demographic characteristics and injury precursors between the two subgroups. Specific injury outcomes were then tested for significance using odds ratios. RESULTS: Alaska residents and nonresidents demonstrated significant differences for both demographic factors and factors describing events leading to injuries, and for injury outcomes. Nonresidents were more likely to be 65 years or older, female, and aboard cruise ships when injuries occurred. Nonresidents were more likely to suffer fracture injuries, to suffer injuries with Abbreviated Injury Scores greater than 2, to experience posthospital discharges to sites other than their homes, and to experience postinjury disabilities. CONCLUSIONS: Alaska residents and nonresidents in this study showed significant differences in demographics, precipitating events, and injury outcomes. The findings lend support for targeted safety promotion programs.

Plasmodium falciparum-Malaria in Pregnant African Immigrants Often Goes Unrecognized
- 2012
-
Ingår i: Journal of Travel Medicine. - : Oxford University Press (OUP). - 1195-1982 .- 1708-8305. ; 19:6, s. 380-382
-
Tidskriftsartikel (refereegranskat)abstract
- We report four cases of asymptomatic Plasmodium falciparum malaria in pregnant African women. They had immigrated to Finland 3 to 13 months earlier. The disease was revealed only by anemia. The diagnosis relied on blood smear which showed a parasitemia <0.2% in three cases. Medical personnel should be informed about the possibility of afebrile forms of malaria in pregnant women even months after immigration. Very low levels of parasitemia may call for a more sensitive diagnostic approach such as polymerase chain reaction.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: International travellers contribute to the rapid spread of Zika virus (ZIKV) and its sentinel identification globally. We describe ZIKV infections among international travellers seen at GeoSentinel sites with a focus on ZIKV acquired in the Americas and the Caribbean, describe countries of exposure and traveller characteristics, and assess ZIKV diagnostic testing by site. Methods: Records with an international travel-related diagnosis of confirmed or probable ZIKV from January 2012 through December 2019 reported to GeoSentinel with a recorded illness onset date were included to show reported cases over time. Records from March 2016 through December 2019 with an exposure region of the Americas or the Caribbean were included in the descriptive analysis. A survey was conducted to assess the availability, accessibility and utilization of ZIKV diagnostic tests at GeoSentinel sites. Results: GeoSentinel sites reported 525 ZIKV cases from 2012 through 2019. Between 2012 and 2014, eight cases were reported, and all were acquired in Asia or Oceania. After 2014, most cases were acquired in the Americas or the Caribbean, a large decline in ZIKV cases occurred in 2018-19. Between March 2016 and December 2019, 423 patients acquired ZIKV in the Americas or the Caribbean, peak reporting to these regions occurred in 2016 [330 cases (78%)]. The median age was 36 years (range: 3-92); 63% were female. The most frequent region of exposure was the Caribbean (60%). Thirteen travellers were pregnant during or after travel; one had a sexually acquired ZIKV infection. There was one case of fetal anomaly and two travellers with Guillain-Barre syndrome. GeoSentinel sites reported various challenges to diagnose ZIKV effectively. Conclusion: ZIKV should remain a consideration for travellers returning from areas with risk of ZIKV transmission. Travellers should discuss their travel plans with their healthcare providers to ensure ZIKV prevention measures are taken.

LeishMan recommendations for treatment of cutaneous and mucosal leishmaniasis in travelers, 2014.
- 2014
-
Ingår i: Journal of Travel Medicine. - : Oxford University Press (OUP). - 1195-1982 .- 1708-8305. ; 21:2, s. 116-29

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Treatment of cutaneous leishmaniasis (CL) and mucosal leishmaniasis (ML) in travelers is still controversial. Over the last decade, national and international consortia have published recommendations for treating CL in travelers. These guidelines harmonize many issues, but there are some discrepancies.METHODS: Leishmania parasites causing CL can now be genotyped by polymerase chain reaction techniques for detecting Leishmania DNA. Therefore, treatment recommendations can now be species based rather than based on geographical exposure. To review the evidence on which the recommendations were based, "LeishMan" (Leishmaniasis Management), a group of experts from 13 institutions in eight European countries, performed a PubMed MEDLINE) literature search and considered unpublished evidence and the experts' own personal experiences. The Oxford evidence grading system was used to evaluate the information.RESULTS AND CONCLUSION: In this article, the authors provide practical treatment recommendations for imported CL and ML in Europe, drawn up from the review by the European experts.

- We need to rapidly detect and respond to public rumours, perceptions, attitudes and behaviours around COVID-19 and control measures. The creation of an interactive platform and dashboard to provide real-time alerts of rumours and concerns about coronavirus spreading globally would enable public health officials and relevant stakeholders to respond rapidly with a proactive and engaging narrative that can mitigate misinformation.

Pre-travel advice, attitudes and hepatitis A and B vaccination rates among travellers from seven countries
- 2017
-
Ingår i: Journal of Travel Medicine. - : Oxford University Press. - 1195-1982 .- 1708-8305. ; 24:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Knowledge about the travel-associated risks of hepatitis A and B, and the extent of pre-travel health-advice being sought may vary between countries.METHODS: An online survey was undertaken to assess the awareness, advice-seeking behaviour, rates of vaccination against hepatitis A and B and adherence rates in Australia, Finland, Germany, Norway, Sweden, the UK and Canada between August and October 2014. Individuals aged 18-65 years were screened for eligibility based on: travel to hepatitis A and B endemic countries within the past 3 years, awareness of hepatitis A, and/or combined hepatitis A&B vaccines; awareness of their self-reported vaccination status and if vaccinated, vaccination within the last 3 years. Awareness and receipt of the vaccines, sources of advice, reasons for non-vaccination, adherence to recommended doses and the value of immunization reminders were analysed.RESULTS: Of 27 386 screened travellers, 19 817 (72%) were aware of monovalent hepatitis A or combined A&B vaccines. Of these 13 857 (70%) had sought advice from a healthcare provider (HCP) regarding combined hepatitis A&B or monovalent hepatitis A vaccination, and 9328 (67%) were vaccinated. Of 5225 individuals eligible for the main survey (recently vaccinated = 3576; unvaccinated = 1649), 27% (841/3111) and 37% (174/465) of vaccinated travellers had adhered to the 3-dose combined hepatitis A&B or 2-dose monovalent hepatitis A vaccination schedules, respectively. Of travellers partially vaccinated against combined hepatitis A&B or hepatitis A, 84% and 61%, respectively, believed that they had received the recommended number of doses.CONCLUSIONS: HCPs remain the main source of pre-travel health advice. The majority of travellers who received monovalent hepatitis A or combined hepatitis A&B vaccines did not complete the recommended course. These findings highlight the need for further training of HCPs and the provision of reminder services to improve traveller awareness and adherence to vaccination schedules.

Viral load dynamics and shedding kinetics of mpox infection: a systematic review and meta-analysis
- 2023
-
Ingår i: Journal of Travel Medicine. - : OXFORD UNIV PRESS INC. - 1195-1982 .- 1708-8305. ; 30:5

Tidskriftsartikel (refereegranskat)abstract
- Background Viral load dynamics and shedding kinetics are critical factors for studying infectious diseases. However, evidence on the viral dynamics of mpox remains limited and inconclusive. Thus, we aimed to provide a comprehensive understanding of the viral load and viability of the re-emerged mpox virus since 2022.Methods For this systematic review and meta-analysis, we searched PubMed/MEDLINE, Embase and Google Scholar for published articles that are related to mpox viral dynamics up to April 2023.Results From 19 studies, 880 samples and 1477 specimens were collected. The pooled median Ct values appeared in the following order: skin lesion [Ct value 21.7 (IQR 17.8-25.5)], anorectal [22.3 (16.9-27.6)], saliva [25.9 (22.5-31.1)], oral [29.0 (24.5-32.8)], semen [29.6 (25.9-33.4)], urine [30.5 (24.6-36.4)], pharyngeal [31.9 (26.5-37.3)], urethra [33.0 (28.0-35.0)] and blood [33.2 (30.4-36.1)]. People living with human immunodeficiency virus (HIV) have a lower Ct value in the skin [skin HIV+, 19.2 (18.3-20.0) vs skin HIV-, 25.4 (21.2-29.0)]. From the Ct values and test day since symptom onset, we identified temporal trends of viral load for each specimen type. Changes in the trend were observed at 4 days in saliva, 5 days in blood, 6 days in skin, 7 days in anorectal, urine, semen and pharyngeal and 8 days in the urethra. We determined optimal Ct cutoff values for anorectal (34.0), saliva (27.7) and urethra (33.0) specimens, where a Ct value above each cutoff suggests minimal viral viability. Using these cutoff values, we derived the duration of viable viral isolation in each specific specimen type (anorectal 19 days, saliva 14 days and urethra 14 days).Conclusion Skin lesion, anorectal and saliva samples contained the highest viral load. The peak viral load manifests within 4-8 days after symptom onset, and viable virus detection was presumed to cease within 14-19 days from symptom onset in anorectal, saliva and urethral samples.
