A resolution designating February 27, 2025, as "Rare Disease Day".

S.Res. 104 proposes to designate February 27, 2025, as Rare Disease Day in the United States. This non-binding resolution aims to recognize and raise awareness about rare diseases and the importance of medical research and diagnostic methods for conditions that affect relatively small populations.

As a non-binding resolution, this measure does not have the force of law and does not require presidential signature. Instead, it serves as a symbolic gesture from Congress to highlight rare diseases and promote health awareness and prevention efforts. The resolution was introduced by Senator John Barrasso on February 27, 2025, and remains in the early stages of the legislative process.
