ISTM Foundation

Refugees The ISTM Foundation, Inc., promotes and fosters healthy and safe travel — it focuses not only on travellers, but also on their destination and on their home communities. With increasing global mobility, health and safety issues for everyone becomes more and more critical. This applies to the movement of refugees and migrants, to tourists including low budget backpackers, to humanitarian aid workers, to business travellers, to the military and government employees, and even to sports and entertainment figures who spend much of their time traveling.

Refugees The Foundation's mission is to support the scientific underpinnings of the fields of travel and tropical medicine in order to best provide for the health and well-being of all travellers. The Foundation also acts to raise awareness of social, environmental, cultural and health issues resulting in part from travel and tourism within destination communities, with the responsibility to encourage and conduct research and develop strategies to protect these local communities from the negative impacts of tourism.

The ISTM Foundation, established 2014, is guided by:

President: Bradley Connor, United States of America

Bradley A. Connor Bradley A. Connor, M.D. is a Clinical Professor of Medicine at the Weill Medical College of Cornell University and Attending Physician at the New York Presbyterian Hospital. He is founder and Medical Director of Travel Health Services, New York’s first private travel medicine clinic. Dr. Connor is also the director of the New York Center for Travel and Tropical Medicine, a facility devoted to teaching and research in travel and tropical medicine. Dr. Connor has been in the private practice of Gastroenterology and Tropical Medicine for the past 30 years.

His main research interests include chronic gastrointestinal disorders in returned travelers, emerging gastrointestinal pathogens, and enteric parasitic diseases. He was part of the Kathmandu, Nepal team that first described the clinical illness associated with Cyclospora infections and made subsequent contributions to the understanding of its pathogenesis, epidemiology, and treatment. Widely published in these fields, he is co-editor of the textbook Travel Medicine, now in its 3rd edition.

Dr. Connor was the Co-Chair of the ISTM Foundation and CDC sponsored Travelers’ Diarrhea Consensus Conference, held in April 2016. New guidelines for the diagnosis and management of Travelers’ Diarrhea were developed during this conference and the proceedings will be published in early 2017.

This was the first international Consensus Conference on this subject in over a decade and was prompted by the availability of new culture independent diagnostics such as Film Array and the growing awareness of the potential for acquisition of multi drug resistant bacteria as a result of travel and the use of antibiotics. Dr. Connor has been the author of the sections on Travelers’ Diarrhea and Persistent Diarrhea in the CDC Health Information for International Travel "Yellow Book" for the past six years. In his clinical practice Dr. Connor was an early adopter of the BioFire FilmArray GI panel, the first physician in private practice in New York to utilize this new diagnostic technology as early as April 2014 and has now accumulated over two and a half years’ worth of data on diarrhea in returned travelers as well as community acquired cases.

Dr. Connor is Past President of the International Society of Travel Medicine (ISTM) an organization of over 3000 physicians and allied health professionals in over 75 countries. He is a consultant to the Centers for Disease Control and Prevention (CDC) and has been part of the Health Information for International Travel working group in the Division of Global Migration since 1997. He is the New York City site director for GeoSentinel, the emerging infectious diseases network of the CDC and ISTM. Dr. Connor was a member of the task force on Travel Medicine at the World Health Organization (WHO) in 2003. Dr. Connor has served as a consultant to the White House Medical Unit in the Clinton and Bush administrations and is an advisor in Travel Medicine for the U.S. Olympic Swim Team.

Dr. Connor received his medical degree from the University of Texas Southwestern Medical School in Dallas. He completed both his internship and residency in internal medicine at the University of Texas Health Science Center Hospitals in San Antonio and his fellowship in gastroenterology at the New York Hospital-Cornell University Medical College.

Activities and Projects

International Migration Conference. Human migration is now at an all-time high, accounting for 240 million persons and is shaping world events and fueling political and public debates. People have been migrating since the beginning of human history to escape natural catastrophes, wars and suffering. As a result, migrant populations are heterogeneous and are facing a broad range of health needs. Migrant medicine is a rapidly developing discipline to address the complexity of such needs.

The ISTM is planning an international forum in October of 2018 to discuss scientific evidence on migration-related issues, with a specific focus on the health aspects affecting migrant populations and host communities. This forum will bring together public officials, policy makers, clinicians and others who care for migrants and their introduction into their host communities.

Annual travel medicine research grants. Grants are awarded through a peer review process, and are designed to stimulate travel medicine research by supporting pilot studies or small research projects. These awards typically assist young or newer investigators and investigators in lower income communities to learn skills in investigative work and test hypotheses so that they may then apply to other agencies for more substantive research grants.

Our goal is to support needed research by promising young researchers who may not otherwise find funding, as federal and other institutional research support becomes more difficult to obtain. By cosponsoring awards, we hope to expand the awareness of our awards among the research community and attract the best possible candidates each year. We award research grants on global health, travel medicine and migration medicine issues.

Biennial travel grants for ISTM conference presenters. Travel grants and a waiver of registration fees are awarded to presenters of abstracts from resource-poor countries as well as to young investigators who otherwise do not have the funding to attend international conferences.

GeoSentinel. This emerging infectious disease network was created in 1995 as a joint project between the International Society of Travel Medicine (ISTM) and the U.S. Centers for Disease Control and Prevention (CDC).

With the recognition of growing problems related to emerging infectious diseases, global health security has become an important agenda item for many countries. New microbes, drug resistance, the potential for accidental or purposeful release of hazardous bioagents, and the globalization of travel and trade continue to be serious challenges.

The U.S government recognized with GeoSentinel's creation that real- time evaluation and reporting of illness in returned travelers (tourists, missionaries, migrants etc.) across multiple sites in multiple continents could serve as an early warning for incipient epidemics and spread of infectious diseases from one country to another. Over the past 20 years, the GeoSentinel Surveillance network has provided robust data that for the first time defined the spectrum of illness and its relation to place of exposure for many significant health risks that face travelers and migrants. GeoSentinel has several major objectives that include serving as an emerging infections sentinel network to conduct surveillance for emerging infectious diseases; rapidly sharing novel data on emerging infections with participating sites, internet information services, and public health authorities (e.g. World Health Organization, European CDC, Public Health Agency of Canada, US CDC); and analyzing, presenting, and publishing surveillance results collaboratively with CDC, GeoSentinel sites, and our two regional partners, CanTravNet and EuroTravNet.
