Washington (CNN) House Speaker Nancy Pelosi said Sunday a third legislative package is in the works in response to the spread of coronavirus and urged lawmakers to promote social distancing in their Washington, DC, offices out of an abundance of caution.

"We have already begun work to develop a third emergency response package that will continue to put Families First," Pelosi said in a statement to lawmakers. "In bipartisan consultation with the Attending Physician and the Sergeant at Arms, and out of an abundance of caution, I am writing to encourage you to take steps to promote social distancing within your Washington, D.C. office as we engage in the District Work Period. This may entail more than half of your Washington staff teleworking from home."
