Tertiary students are at risk of acquiring infectious diseases during overseas travel as they visit low-income countries, have low perceptions of risk and are unlikely to access travel health advice. Some will visit friends and relatives abroad, a group identified as disproportionately affected by imported infections. There is no national student travel health policy in NZ. This study aimed to explore travel health training of university-based health providers; academics' practices and perceptions of travel health; reasons for travel and countries visited by NZ university students, their travel health uptake and factors affecting decision making about this. ⋯ A national policy is warranted involving all stakeholders, utilizing innovative technologies to increase uptake of student travel health services.

There is increasing recognition of the contribution of community-acquired cases to the global burden of Clostridium difficile infection (CDI). The epidemiology of CDI among international travellers is poorly understood, and factors associated with international travel, such as antibiotic use and changes in gut microbiota, could potentially put travellers at higher risk. ⋯ CDI is encountered in returning international travellers, although there is considerable variability in testing practices. These data underscore the importance of awareness of C. difficile as a potential cause of travel-associated diarrhoea.

Hajj is one of the largest and the most ethnically and culturally diverse mass gatherings worldwide. The use of appropriate surveillance systems ensures timely information management for effective planning and response to infectious diseases threats during the pilgrimage. The literature describes infectious diseases prevention and control strategies for Hajj but with limited information on the operations and characteristics of the existing Hajj infectious diseases surveillance systems. ⋯ There is need to integrate the existing Hajj surveillance data management systems and to implement syndromic surveillance as an early warning system for infectious disease control during Hajj. International engagement is important to strengthen Hajj infectious diseases surveillance and to prevent disease transmission and globalization of infectious agents which could undermine global health security.

Businesses increasingly conduct operations in remote areas where medical evacuation [Medevac(s)] carries more risk. Royal Dutch Shell developed a remote healthcare strategy whereby enhanced remote healthcare is made available to the patient through use of telemedicine and telemetry. To evaluate that strategy, a review of Medevacs of Shell International employees [i.e. expatriate employees (EEs) and frequent business travellers (FBTs)] was undertaken. ⋯ This study uniquely provides a benchmark Medevac rate (4 per 1000) for EEs and FBTs and demonstrates that Medevac rates are highest from countries identified as 'high risk'; there is an age and gender bias, and pre-existing medical conditions are of notable relevance. It confirms a change in the trend from injury to illness as a reason for Medevac in the oil and gas industry and demonstrates that diagnoses of a digestive and traumatic nature are the most frequent. A holistic approach to health (as opposed to a predominant focus on fitness to work), more attention to female travellers, and the application of modern technology and communication will reduce the need for Medevacs.

Vaccination is a safe and effective public health intervention that not only protects individual travellers from vaccine-preventable diseases (VPDs), but prevents them from becoming a source of disease in their destination and on their return. Obtaining an accurate vaccination history from travellers during a pre-travel review can be difficult; serology may be used to identify patients who are non-immune to specific diseases in order to guide vaccination requirements. Clinically relevant data about the usefulness of serology in this setting are lacking. We performed a retrospective audit of pre-travel VPD serology requested by practitioners of a busy community-based travel clinic. ⋯ Serology can be a useful tool in the identification of non-immune travellers to enable targeted vaccination prior to travel. We recommend that travel health clinicians assess patients' vaccination and infection histories, and strongly consider serology or vaccination where there is doubt about immunity. This will help protect the traveller and prevent importation of disease into destination or home communities.
