There will be 'dramatic' change in coronavirus spread if Americans follow guidelines

There will be a "dramatic" change in the spread of coronavirus if Americans follow guidelines issued by the White House on Monday to fight virus, a member of the White House coronavirus task force said.

"If everybody in America does what we ask for over the next 15 days, we will see a dramatic difference," Deborah Birx, White House coronavirus response coordinator, said at a White House briefing also addressed by President Donald Trump. The recommendations included avoiding social gatherings of more than 10 people. Birx said one of the most important steps was that if one person in a household became infected, the whole household should self-quarantine for 14 days.
