Context The numbers of university students studying abroad increase every year. These students are not tourists as their studies require different types of travel that expose them to different risks. Moreover, health care students ( HCSs) may be exposed to even greater risks according to their travel destinations and itineraries. Clearly, research-based pre-travel advice is needed. Methods This study reports on a prospective survey conducted from April 2010 to January 2014 of health care and non-health care students from Swedish universities in Umeå, Stockholm and Gothenburg studying abroad. Results Of the 393 students included in the study, 85% responded. Over half (55%) were HCSs. Pre-travel health information was received by 79% and information on personal safety by 49% of HCSs. The rate of illness during travel was 52%. Health care students more often travelled to developing regions and were at increased risk for travellers' diarrhoea. One in 10 experienced theft and 3% were involved in traffic accidents. One in five met a new sexual partner during travel and 65% of these practised safe sex. Half of all participants increased their alcohol consumption while abroad; high alcohol consumption was associated with increased risk for being a victim of theft, as well as for meeting a new sexual partner during travel. Conclusions University authorities are responsible for the safety and well-being of students studying abroad. This study supplies organisers and students with epidemiological data that will help improve pre-travel preparation and increase student awareness of the potential risks associated with studying abroad.

Background: Travel health advice is an important and difficult part of a pre-travel consultation. The aim of this study was to determine whether the travel health advice given is followed by the traveller and whether it affects disease and injury experienced during travel. Methods: A prospective survey study was carried out from October 2009 to April 2012 at the Travel Medicine Clinic of the Department of Infectious Diseases, Umeå University Hospital, Umeå, Sweden. The Travel Medicine Clinic in Umeå is the largest travel clinic in northern Sweden. Results: We included 1277 individuals in the study; 1059 (83%) responded to the post-travel questionnaire. Most visitors (88%) remembered having received travel health advice; among these, 95% found some of the health advice useful. Two-thirds (67%) claimed to have followed the advice, but fell ill during travel to the same extent as those who did not. Younger travellers (< 31 y) found our travel health advice less beneficial, were less compliant with the advice, took more risks during travel, and fell ill during travel to a greater extent than older travellers. Conclusions: Helping travellers stay healthy during travel is the main goal of travel medicine. Younger travellers are a risk group for illness during travel and there is a need to find new methods to help them avoid illness. Travellers find travel health advice useful, but it does not protect them from travel-related illness. Factors not easily influenced by the traveller play a role, but a comprehensive analysis of the benefits of travel health advice is needed. [ABSTRACT FROM AUTHOR]

Background: Prediction of timing for the onset and peak of an influenza pandemic is of vital importance for preventive measures. In order to identify common spatiotemporal patterns and climate influences for pandemics in Sweden we have studied the propagation in space and time of A(H1N1)pdm09 (10,000 laboratory verified cases), the Asian Influenza 1957–1958 (275,000 cases of influenza-like illness (ILI), reported by local physicians) and the Russian Influenza 1889–1890 (32,600 ILI cases reported by physicians shortly after the end of the outbreak). Methods: All cases were geocoded and analysed in space and time. Animated video sequences, showing weekly incidence per municipality and its geographically weighted mean (GWM), were created to depict and compare the spread of the pandemics. Daily data from 1957–1958 on temperature and precipitation from 39 weather stations were collected and analysed with the case data to examine possible climatological effects on the influenza dissemination. Results: The epidemic period lasted 11 weeks for the Russian Influenza, 10 weeks for the Asian Influenza and 9 weeks for the A(H1N1)pdm09. The Russian Influenza arrived in Sweden during the winter and was immediately disseminated, while both the Asian Influenza and the A(H1N1)pdm09 arrived during the spring. They were seeded over the country during the summer, but did not peak until October-November. The weekly GWM of the incidence moved along a line from southwest to northeast for the Russian and Asian Influenza but northeast to southwest for the A(H1N1)pdm09. The local epidemic periods of the Asian Influenza were preceded by falling temperature in all but one of the locations analysed. Conclusions: The power of spatiotemporal analysis and modeling for pandemic spread was clearly demonstrated. The epidemic period lasted approximately 10 weeks for all pandemics. None of the pandemics had its epidemic period before late autumn. The epidemic period of the Asian Influenza was preceded by falling temperatures. Climate influences on pandemic spread seem important and should be further investigated. [ABSTRACT FROM AUTHOR]

Background: The Travel Medicine Clinic in Umeåå is one of Sweden's largest public providers of vaccination and counselling prior to international travel. During the study period it was the only travel medicine clinic in Umeåå. This study describes the demography of the visitors to the clinic and travel destinations and durations, as well as vaccinations administered. Methods: This was a retrospective study for the period January 2005 to April 2008 based on pre-travel consultation questionnaires and on vaccine expenditure data. A 10% sample of 16,735 first visits prior to international travel was consecutively selected according to the chronology of the visits. Results: Data on 1698 travellers were included in the study. Thailand was the most common destination among visitors, accounting for one third of all destinations. Medical problems affecting pre-travel health planning were rare. Four out of 5 visitors (79%) received only 1 vaccination, mainly for hepatitis A. Travellers to Thailand more often sought travel health advice compared to travellers to Turkey, despite the fact that the 2 destinations were almost equally distributed among travellers from Umeåå. We found differences between men and women in money spent on vaccines and in particular in vaccination against Japanese encephalitis. Conclusions: To assess the optimal vaccination level at a travel medicine clinic is difficult. Decisions are affected by general recommendations and the risk perception of the travel medicine practitioner, as well as the risk perception of the traveller. The sex difference found in this study might be due to gender differences in risk perception and should be further investigated. [ABSTRACT FROM AUTHOR]

The article focuses on the relationship between climate change and invasive meningococcal disease (IMD). It says that IMD was highly influenced by climatic factors such as spatial distribution and seasonality. It mentions that absolute humidity and land-cover type are associated to IMD epidemics. It says that the early warning systems (EWS) can serve as a useful meteorological surveillance device to predict IMD epidemics through the identification of climatic factors that affect IMD.

The article focuses on the influence of climate change on invasive meningococcal disease (IMD). It states that IMD is a disease caused by Neisseria meningitidis which is mainly found in the upper respiratory tract (URT), and is transferred through respiratory secretion or saliva. It adds that climate change affects IMD in two ways such as geographical distribution and seasonality. It adds that climatic factors including air humidity, rainfall, and dust are also associated with the spread of IMD.

We investigated the potential role of Antarctic tourism in the introduction of human-associated pathogens into Antarctic wildlife. We collected and analyzed 233 fecal samples from eight bird species. The samples were collected at six localities on the Antarctic Peninsula, which often is visited by tourists. Every sample was investigated for pathogens of potential human origin: Campylobacter jejuni, Salmonella spp., and Yersina spp. None of these bacteria was found. Our data suggest that the tourism industry so far has achieved its goal of not introducing pathogens into the Antarctic region. There is, however, an urgent need to further investigate the situation in areas closer to permanent Antarctic settlements. [ABSTRACT FROM AUTHOR]
