Tuesday (April 7) is World Health Day, and music stars from Mariah Carey to Meek Mill gave healthcare workers a virtual round of applause for working to combat coronavirus.

Twitter tagged the two artists in a list of celebrities to tweet clapping emojis to celebrate healthcare workers on the global health awareness day, sponsored by the World Health Organization. The virtual practice mimics people’s evening ovations across the globe, as they stand on their balconies or front porches to clap and/or holler in gratitude and support for healthcare workers.

That echo now resonates in digital form. Mill, Carey, Shakira, Sam Smith, Liam Gallagher and more celebrities asked fans to nominate their personal healthcare heroes or recognize themselves as frontline workers.
