The numbers behind World Thrombosis Day: What every blood clot advocate should know
August 25, 2026
Blood clots remain one of the most preventable causes of death and disability worldwide, yet they are also among the least talked about. As you prepare your World Thrombosis Day materials, here are a few data points worth knowing and sharing.
- 1 in 4 people worldwide die from conditions caused by thrombosis
- 60% of venous clots occur during or after hospitalization, making hospital-associated clots a leading cause of preventable death.
- VTE causes more deaths each year in the U.S. and Europe than breast cancer, HIV disease and motor vehicle crashes combined.
- Awareness gaps persist among the general public, particularly around recognizing early symptoms.
These numbers are not just statistics. Use them in a flyer, download our social media images or start a conversation with a colleague or friend to make the case for getting involved this October 13.
