I was part of a medical team that worked in the North Eastern province of the Democratic Republic of Congo participating in areas of community health, hospital care and teaching. During the one year spent in the D.R.C., I was struck by the morbidity and mortality burden of malaria.

Upon returning to Canada, my husband (family physician) and I established a travel health/medicine centre in our community of Cobourg, Ontario. I joined ISTM in 1999 and obtained the C.T.H. in 2007. Within a couple years I extended our services to include a mobile service which prepared groups of college and university students travelling abroad for education or volunteer work. I also established travel health services at a second location in Lindsay, Ontario.

Responsible Traveller: Jim Bond, Scotland, United Kingdom

Jim Bond Jim was born and brought up in Zambia and is still very much an African at heart. He initially studied Medicine at Newcastle upon Tyne, completing a broad, practical postgraduate medical training in the UK and South Africa. He has worked in a number of African countries and Madagascar, both as a rural hospital practitioner and public health doctor. After returning to Scotland in 1998, he has worked in HIV palliative care, infectious diseases, public health and occupational medicine. He has practised clinical travel medicine since 1999.

Jim’s passion for plants and ethnobotany (the traditional knowledge and use of plants by local peoples) enabled him to work closely with traditional healers in Madagascar, South Africa and Mozambique, collaborating to address local priorities such as TB diagnosis and treatment supervision, HIV prevention and community-led antiretroviral therapy, and developing communications and appropriate ambulance services for obstetric emergencies.

Throughout his life, Jim has been privileged to explore some of the more remote and less known corners and waterways of Africa, Madagascar and South America, more often than not by canoe or on foot. First formally trained in expedition medicine in 1995, he has since led and/or acted as expedition doctor to a number of research, adventure and artwork expeditions, all with a strong focus on community participation.

Jim currently practises as a consultant in Travel & Expedition Medicine at an independent, specialist travel clinic in Edinburgh, and as an occupational health physician at a private hospital in the same city. He is a Fellow of the Faculty of Travel Medicine in Glasgow, where he is also teaches and is an examiner for the Membership Diploma course.

His long-term career interests include doing more community-led rabies and schistosomiasis (bilharzia) elimination work in Africa and Madagascar.
