What is the ISTM Certificate of KnowledgeTM?

The Certificate recognizes individual excellence in knowledge in the field of travel medicine, associated with pre-travel care and consultation. It is the first step in the ISTM Travel Medicine Continuous Professional Development Program. The exam focuses specifically on the level of knowledge that is necessary to practice travel medicine. Knowledge of specific tropical diseases and treatments will be limited to that which should be known to advise travellers (for example, in the diagnosis and treatment of traveller's diarrhea or rabies immunoprophylaxis), including post-travel triage of travellers and post-travel screening. Knowledge of tropical medicine is not required.

Developed by an international panel of travel medicine experts representing a variety of professional disciplines, the Certificate will be awarded to eligible professionals who pass the Certificate of Knowledge Examination. The Certificate is a symbol of your achievement in the field - proof of your commitment to excellence. Those passing the examination will receive a Certificate of Knowledge and will be granted a "Certificate in Travel Health™" or "CTH®" that must be maintained every ten years to remain active. ISTM members who have been awarded and maintain the Certificate will also be recognized in the ISTM Directory of Travel Medicine Providers and within the Travel Clinic section of the ISTM website.

What are the Purposes of the Program?

The ISTM Certificate of KnowledgeTM Program was created to:

  • Establish an international standard for travel medicine practitioners
  • Encourage individual and global professional development in the area of travel medicine
  • Formally recognize individuals who pass the Certificate of KnowledgeTM Examination
  • Serve the public by promoting quality travel medicine services
  • Demonstrate the global validity of epidemiological data and of preventive strategies

Why has the ISTM developed a Travel Medicine Continuing Professional Development Program?

The practice of travel medicine is an ever changing environment. To keep current with recent developments, along with new treatments and new challenges, travel medicine professionals must take active steps to remain current in their knowledge and practices. The new ISTM Program will now reward those practitioners who participate in activities to keep up to date with the most recent developments in the field. This process will provide greater confidence to the public and patients we treat, and enable the CTH® holders demonstrate to compliance authorities that the credential is relevant. Additionally, these activities will enhance and elevate the practice of travel medicine around the world.

I received by CTH® Certificate before the 2011 examination, will I have to participate?

No. The Travel Medicine Continuing Professional Development Program becomes effective with those achieving the CTH® by successfully negotiating the 2011 examination. Those who were awarded certificates before 2011 are not affected by the new program. The ISTM supports professional development activities for travel medicine practitioners to remain current in the field. CTH® holders who received their certificates before 2011 are encouraged (and not mandated) to consider participating during or prior to 2018 on a voluntary basis. Those who choose to participate will be recognized as such.
