CSL sponsored illuminations at multiple sites on 28 February to add some after-sunset sparkle to Rare Disease Day 2026.

The light displays were associated with CSL locations in Philadelphia; Kankakee, Illinois; Marburg, Germany; and Bern, Switzerland. The day recognizes the 300 million people across the world who live with 10,000 known rare diseases.
