On Wednesday, former President Barack Obama urged Americans to continue with social distancing, despite the wishes of some to reopen the economy in two weeks, as the spread of coronavirus continues.

On Twitter, Obama shared a story about healthcare workers who are scared and overwhelmed with the caption, …another reason to maintain social distancing policies at least until we have comprehensive testing in place. Not just for our sake—for theirs.

Obama also wrote, These are the burdens our medical heroes already face in NYC. It’s only going to get harder across the country. May we all model our own behavior on their selflessness and sacrifice as we help each other through this.
