Background Infectious disease epidemiology is continuously shifting. While travel has been disrupted by the COVID-19 pandemic and travel-related epidemiological research experienced a pause, further shifts in vaccine-preventable diseases (VPDs) relevant for travellers have occurred. Methods We conducted a literature search on the epidemiology of travel-related VPD and synthesized data for each disease with a focus on symptomatic cases and on the impact of the respective infection among travellers, considering the hospitalization rate, disease sequela and case fatality rate. We present new data and revised best estimates on the burden of VPD relevant for decisions on priorities in travel vaccines. Results COVID-19 has emerged to be a top travel-related risk and influenza remains high in the ranking with an estimated incidence at 1% per month of travel. Dengue is another commonly encountered infection among international travellers with estimated monthly incidence of 0.5–0.8% among non-immune exposed travellers; the hospitalized proportion was 10 and 22%, respectively, according to two recent publications. With recent yellow fever outbreaks particularly in Brazil, its estimated monthly incidence has risen to >0.1%. Meanwhile, improvements in hygiene and sanitation have led to some decrease in foodborne illnesses; however, hepatitis A monthly incidence remains substantial in most developing regions (0.001–0.01%) and typhoid remains particularly high in South Asia (>0.01%). Mpox, a newly emerged disease that demonstrated worldwide spread through mass gathering and travel, cannot be quantified regarding its travel-related risk. Conclusion The data summarized may provide a tool for travel health professionals to prioritize preventive strategies for their clients against VPD. Updated assessments on incidence and impact are ever more important since new vaccines with travel indications (e.g. dengue) have been licensed or are undergoing regulatory review.

Over the past 20 years, there has been an increase in the number of students undertaking traditional research masters and doctor of philosophy courses in the health sciences. This paper reviews and summarizes several aspects of the literature related to supervision of students in these traditional research higher degree (RHD) programs in Australasia: elements of RHD supervision; use of information and communication technologies in RHD supervision; warning signs for non-completion of RHD candidature; and evaluation of RHD supervision. The growth in traditional RHD enrollments has been paralleled by similar expansion in professional doctorate programs, and this paper draws attention to issues relating to supervision of these professional doctorate students, especially those studying at a distance. It draws on earlier research which compared structures of such programs across Australia and grounded professional doctorate supervision firmly in the workplace. Further, the emerging small body of literature associated with professional doctorate supervision is used to highlight features shared with and those distinct from traditional RHD supervision, and to identify fertile topics for further research into this burgeoning area.
