Rare Disease Day is an annual global event held on February 28 (or February 29 in leap years) to raise awareness of rare diseases and the individuals and families affected by them. An estimated 300 million people worldwide are living with rare diseases. In the United States, a rare disease is defined as one that affects fewer than 200,000 people. Some rare diseases are vector-borne, meaning they are caused by bacteria, viruses, or parasites transmitted by living organisms, often biting arthropods such as ticks and mosquitoes.
This toolkit offers ready-to-use social media resources. Sharing this content helps raise awareness, deepen understanding, and support ongoing research and prevention efforts for rare diseases.
