GeoSentinel PIs David Hamer and Michael Libman will give an update on the project and answer questions from the audience.

“Pregnant women should avoid travel” – but if they still decide to go? This session discusses the fundamentals of pre-travel advice for pregnant travellers.

OBJECTIVES:
• Propose a “checklist” for the pre-travel advice of the pregnant traveller.
• Discuss vaccine issues, challenges of long-haul flights and travel health insurance in the context of the pregnant traveller.
• Outline important features of pre-travel advice for pregnant travellers.

Antimicrobial resistance (AMR) impacts the clinical management of many infections in clinical practice and contributes to significant morbidity and mortality. Apart from the inappropriate use of drugs in humans and animals, travellers can also serve as carriers of AMR from the destination into the host country. Travellers can become colonized by multidrug resistant organisms especially when they use antibiotics in the destination countries. This symposium will review the patterns of drug resistance in Southeast Asia and how travel may contribute to spread.

Victor Lim
Overview of AMR in Southeast Asia
OBJECTIVES:
• Describe the epidemiology of multidrug resistance in various parts of Southeast Asia.
• Review risk factors, problems in diagnosis, and challenges in clinical management.
• Discuss impact on travellers traveling to and from Southeast Asia.

Anu Kantele
Travellers' Role in Propagating AMR
OBJECTIVES:
• Describe the initial steps of colonization in the light of findings of a real-time study abroad.
• Describe the means to prevent the colonization.
• Discuss impact of travel-acquired AMR in the destination country of travellers.

Gagandeep Kang
Tracking International Spread of AMR
OBJECTIVES:
• Review detection tools that track the international spread of AMR.
• Discuss whether phylogenetic analysis is helpful.
• Review clinical applications of phylogenetic analysis.

Why not assess migrants' health status and provide presumptive treatment even before departure towards their new home? - Some countries actually do. But what diseases are relevant in migrants? What diseases should be screened for and how? What treatment should be provided? And is this at all ethical? This workshop will make participants address these questions in an interactive manner and develop solutions.

OBJECTIVES:
• Understand important clinical challenges seen in migrants
• Discuss pathways for an efficient work-up and explain the concept of pre- and post-departure screening of migrants
• Develop screening suggestions for migrants by region of origin and explain their choices.

While there are many studies assessing fever and diarrheal syndromes in returned travellers, there is very little data regarding the spectrum of neurological syndromes in returned travellers, their clinical manifestations and management. Laboratory diagnosis in these infections/syndromes also continues to be challenging. This is a case based workshop which will elucidate the various clinical neurological syndromes in returned travellers, their lab diagnosis and clinical manifestations.

OBJECTIVES:
• Describe the challenges in the diagnosis of CNS infections in the returned travellers.
• Expand on novel diagnostic techniques now available for rapid diagnosis of CNS infections.
• Recognise and manage infectious and non-infectious neurological syndromes encountered in returned travellers.

This workshop is suitable for both beginners and experienced travel health providers alike. The speakers will outline the principles of travel vaccination, aspects of the immune response to vaccines, and risk assessment. Vaccination scheduling and booster vaccine doses will be discussed, as well as the practical elements of vaccine storage, preparation and administration. Dealing with immediate post-vaccination adverse reactions, including anaphylaxis, will also be addressed.

OBJECTIVES:
• Summarize relevant theory on vaccination and the immune response.
• Outline the principles of vaccination scheduling with examples.
• Discuss current gaps in healthcare and digital transformation of healthcare services.
• Discuss practical and future applications for travel medicine.

Travel can be associated with introduction and dissemination of pathogens. Public health systems have been established to prevent, detect, and respond to infectious disease threats including cross-border issues. An overview of public health measures and examples of disease translocation related to population movement will be described.

Robert Steffen
SOS: Recurrent Public Health Emergencies
OBJECTIVES:
• Discuss the declaration of pandemic and Public Health Emergency of International Concern (PHEIC) and impact on crossing borders
• Describe recent PHEIC examples (Ebola, Zika, etc.)
• Describe recent pandemic examples (Covid19, 2009 H1N1) 

Marty Cetron
Populations on the Move: Infectious Disease Concerns

OBJECTIVES:
• Discuss population movement and translocation of infectious diseases
• Discuss some examples (mass gatherings, migration-related, travelers)
• Describe concerns related to Covid19

The older person faces a range of health issues, including medical comorbidities, increased risk of falls, cognitive and sensory impairment, which can have adverse consequences for international travel, ranging from disruption of travel itineraries to serious illness and hospitalisation. This symposium will provide participants with a comprehensive knowledge base to enable them to perform a risk assessment on older travellers in clinical practice and to provide well-informed pre-travel health advice.

Charlie Ericsson
Health Priorities for Aging and the Older Traveller
OBJECTIVES:
• Describe demographic trends in older person travel.
• Identify key travel health risks and protective factors in older travellers.
• Provide pre-travel health advice suitable for older travellers.

Jeff Goad
Complexity of Drug-Drug Interactions in the Older Traveller
OBJECTIVES:
• Address polypharmacy in older adults.
• Consider how prescription drugs may interact with malaria chemoprophylaxis.
• Give advice to older travellers about potential for counterfeit drugs in some destinations.

Federico Gobbi
Immunity, Infection and Vaccination in the Older Traveller
OBJECTIVES:
• Outline physiology of immunosenescence in older individuals.
• Discuss vaccination schedules for older travelers.
• Focus specifically on risk-benefit of yellow fever vaccination in the older traveller.

Despite the rapid growth of new diagnostic technologies which are used in research and for clinical needs, there are still unaccepted gaps in diagnosis of common and important diseases seen in travelers. These infectious diseases, either viral, bacterial or parasitic, have been known for decades and still suffer from gaps in diagnosis. Serology, which is still a key element in diagnosis for either viral, bacterial or parasitic infections, has a minimal sensitivity during the acute phase of the diseases, and lack of specificity with high rate of cross-reactivity with other pathogens. The gold standard of malaria diagnosis remains the blood-smear, a reasonable method, but one which is 120 years old. Thus the key challenge is the need to accelerate the development and deployment of new technologies into the field of travel medicine. This, in turn, will help many host countries to improve their diagnostic capacity and better public health information.

Christina Deschermeier

A variety of clinical manifestations of COVID-19 have been noted in this pandemic, including emerging information regarding the neurological and thrombotic manifestations and the overlap between the two. This case-based workshop will address both of these issues.

OBJECTIVES
• Review neurologic sequelae of COVID-19.
• Discuss thrombotic complications of COVID-19.
• Discuss management of the thrombotic complications.
