METHODS: A PubMed search was performed on HIV or acquired immune deficiency syndrome together with a search for specific vaccines. Review of the literature was performed to develop recommendations on vaccinations for HIV-positive travellers to high-risk destinations.
RESULTS: The immune responses to several vaccines are reduced in HIV-positive people. In the case of vaccines for hepatitis A, hepatitis B, influenza, pneumococcus, meningococcus and yellow fever there is a good body of data in the literature showing reduced immune responsiveness and also to help guide appropriate vaccination strategies. For other vaccines like Japanese encephalitis, rabies, typhoid fever, polio and cholera the data are not as robust; however, it is still possible to gain some understanding of the reduced responses seen with these vaccines.
CONCLUSION: This review provides a summary of the immunological responses to commonly used vaccines for the HIV-positive travellers. This information will help guide travel medicine practitioners in making decisions about vaccination and boosting of travellers with HIV.
METHODS: A literature search was conducted on PubMed, Google Scholar, and Scopus using keywords related to recreational substances and international travellers. A total of 11 021 articles were reviewed, charted and summarized for the evidence on prevalence, patterns and characteristics of substance abuse and their health- and non-health-related problems on international travellers.
RESULTS: Fifty-eight articles were included. Most were cross-sectional studies and review articles. Twenty articles addressed the prevalence of substance abuse in travellers, 33 looked at characteristics and patterns of substance abuse in travellers and 39 investigated the health- and non-health-related problems from substance abuse. Estimated prevalence of recreational substances abuse varied from 0.7% to 55.0%. Rates of substances abuse were 9.45% to 34.5% for cannabis, 20.4% to 35.9% for alcohol intoxication, 2.82% to 40.5% for MDMA, 2% to 22.2% for cocaine, 2% to 15% for psychedelic agents and 2% for methamphetamine. The prevalence varied according to travellers' characteristics and travel destinations. Direct health problems included neuropsychiatric problems. Indirect problems included accident and unintentional injuries, crime and violence, risky sexual behaviours and sexual violence and blood-borne infections. Non-health-related problems included air rage, deportation and violation of local laws.
CONCLUSION: Substance abuse among international travellers is an underestimated problem that requires intervention. These findings emphasize the importance of addressing this issue to mitigate both health and well-being problems among travellers while promoting safer and more responsible travel experiences. In the context of travel health practices, practitioners should counsel travellers whose itineraries may include substance abuse, informing them about associated risks and consequences.
Methods: A review of the literature was conducted using the PubMed database. Search terms included: 'repatriation of remains', 'death', 'abroad', 'tourism', 'travel', 'travellers', 'travelling' and 'repatriation'. Additional articles were obtained from grey literature sources and reference lists.
Results: The local national embassy, travel insurance broker and tour operator are important sources of information to facilitate the repatriation of the deceased traveller. Formal identification of the deceased's remains is required and a funeral director must be appointed. Following this, the coroner in the country or jurisdiction receiving the repatriated remains will require a number of documents prior to providing clearance for burial. Costs involved in repatriating remains must be borne by the family of the deceased although travel insurance may help defray some of the costs. If the death is secondary to an infectious disease, cremation at the site of death is preferred. No standardized procedure is in place to deal with the remains of a migrant's body at present and these remains are often not repatriated to their country of origin.
Conclusions: Repatriation of human remains is a difficult task which is emotionally challenging for the bereaving family and friends. As a travel medicine practitioner, it is prudent to discuss all eventualities, including the risk of death, during the pre-travel consultation. Awareness of the procedures involved in this process may ease the burden on the grieving family at a difficult time.
METHODS: A set of 74 items based on a conceptual framework analysis underwent revision and its content validity was established. Items were grouped into three domains. A development study was conducted to establish evidence regarding their factorial structure. A construct validation study was then conducted in which the retained items were tested in an independent sample using confirmatory factor analysis (CFA).
RESULTS: Four factors emerged from our development study and were labelled as pre-travel preparation-insect bites, pre-travel preparation-consultation, insulin and glycaemic control and travel risk behaviour. A CFA confirmed the factorial structure identified in the development study in an independent sample. Each factor loading had a significant (P
