World Thrombosis Day: An Award-Winning, Collaborative Global Movement
Recognized on 13 October, World Thrombosis Day (WTD) focuses attention on the often overlooked and misunderstood condition of thrombosis. With thousands of educational events in countries around the world, WTD and its partners place a global spotlight on thrombosis as an urgent and growing health problem. Join the WTD campaign today.
WTD takes place every year on 13 October, the birthday of Rudolf Virchow who was a pioneer in the pathophysiology of thrombosis. A German physician, pathologist, biologist and anthropologist, Virchow developed the concept of "thrombosis" and advanced our understanding of this condition. To learn more, visit the Berlin Museum of Medical History, formerly the Rudolf Virchow's Pathological Museum.
WTD seeks to increase global awareness of thrombosis, including its causes, risk factors, signs/symptoms and evidence-based prevention and treatment. Ultimately, we strive to reduce death and disability caused by the condition.
Our mission supports the World Health Assembly's global target of reducing premature deaths by non-communicable disease by 25 percent by 2025, as well as the World Health Organization's global action plan for the prevention and control of non-communicable diseases between 2013 and 2020.
Highlight the burden of disease (thrombosis in general) and highlight the need for action, specifically underscoring the unrecognized threat and serious consequences (morbidity and mortality) related to venous thromboembolism (VTE) and atrial fibrillation (AFib).
Increase public awareness of the significance, risks, signs and symptoms of thrombosis, specifically VTE and AFib as an important cause of thromboembolic stroke.
Empower individuals to talk with their healthcare providers about their risk for thrombosis and appropriate prevention. Empower individuals to seek immediate medical attention if they have signs and symptoms.
Galvanize organizations in countries across the globe to conduct appropriate and aligned campaigns in their countries and regions.
Begin the process of advocating for "systems of care" to properly prevent, diagnose and treat VTE and AFib.
Each year, the WTD campaign is evaluated and its reach and influence are analyzed. View each previous year's impact report:
WTD was founded in 2014 by the International Society on Thrombosis and Haemostasis (ISTH) in response to members' requests for a focused global awareness day on thrombosis. Led by a global scientific steering committee, more than 175 organizations worldwide participated in the first day, raising much-needed visibility of the condition through special events, educational forums, widespread media coverage and social media.
WTD has won numerous awards for its marketing and communications efforts, including: A Gold Power of A Award (2016) and Gold Circle Award for Overall Excellence (2015) from the American Society of Association Executives (ASAE) and two prestigous Silver Anvil Awards (2016 & 2015) from the Public Relations Society of America (PRSA). Additional awards include: Gold Circle Merit Award (2016) from the ASAE, Award of Excellence (2015) from the PRSA and the Best in Maryland Awards from the PRSA Maryland Chapter.
