As the COVID-19 pandemic unfolded across the globe, the demand for data on the impact of the novel coronavirus on people with MS grew rapidly.

This information was crucial for people with MS and clinicians to make evidence-based decisions on how to manage their condition during the pandemic or in case of a COVID-19 infection. The MS Data Alliance and the MS International Federation (MSIF) have teamed up to set up a Global Data Sharing Initiative and reached out to individuals and organizations across the global MS movement to get involved.
