As international travel increases, travellers may be at increased risk of acquiring infectious diseases not endemic in their home countries. Many journal articles and reference books related to travel medicine cite that between 22-64% of international travellers become ill during or after travel; however, this information is minimal, outdated and limited by poor generalizability. We aim to provide a current and more accurate estimate of the proportion of international travellers who acquire a travel-related illness. ⋯ International travel, travel, illness.

Review Meta Analysis
A meta-analysis of the use of rifaximin to prevent travellers' diarrhoea.
Travellers' diarrhoea affects tens of millions of people travelling to less developed countries or regions annually. There are positive reports of the use of rifaximin, a non-absorbed, gut-selective antibiotic to prevent travellers' diarrhoea. This study will critically review and analyse clinical trials on the subject. ⋯ There is good evidence supporting the use of rifaximin as a chemoprophylactic agent against travellers' diarrhoea, especially in individuals who are at high risk of severe complications from acute infectious diarrhoea. Rifaximin has an excellent tolerability/safety profile and demonstrated efficacy against diarrhoeagenic Escherichia coli and even enteroinvasive bacteria such Campylobacter species. Future studies should study the most effective dosing regimen for rifaximin chemoprophylaxis, as well as profile local antimicrobial resistance/susceptibility data in less developed regions to further guide rifaximin use.

Influenza outbreaks can occur among passengers and crews during the Alaska summertime cruise season. Ill travellers represent a potential source for introduction of novel or antigenically drifted influenza virus strains to the United States. From May to September 2013-2015, the Alaska Division of Public Health, the Centers for Disease Control and Prevention (CDC), and two cruise lines implemented a laboratory-based public health surveillance project to detect influenza and other respiratory viruses among ill crew members and passengers on select cruise ships in Alaska. ⋯ The high yield of positive results indicated that influenza was common among passengers and crews sampled with ARI. This finding reinforces the need to bolster influenza prevention and control activities on cruise ships. Laboratory-based influenza surveillance on cruise ships may augment inland influenza surveillance and inform control activities. However, these benefits should be weighed against the costs and operational limitations of instituting laboratory-based surveillance programs on ships.

Travellers are at risk of acquiring infectious diseases during travel, with risks differing by destination, travel and traveller characteristics. A pre-travel health consultation may minimize this risk. However, uptake of pre-travel health advice remains low. We investigated pre-travel health preparations and disease-specific risk behaviours among notified cases of selected travel-associated infectious diseases imported into Australia. ⋯ Pre-travel health advice seeking practices and vaccine uptake was suboptimal among cases of notified disease. The results of this study highlight the need for a better understanding of barriers to pre-travel health seeking, particularly among high risk travellers, to reduce the importation of infectious diseases into Australia.

There are several possible malaria prevention strategies for travellers. In Switzerland, chemoprophylaxis (CP) is recommended for persons visiting areas highly endemic for malaria and stand-by emergency treatment (SBET) for areas with moderate to low risk. ⋯ This study shows the considerable decline of antimalarial prescription for chemoprophylaxis that occurred over the 10-year period in favour of SBET.
