Anthony Fauci, White House health adviser, warned that if localities rushed to reopen, the consequences could be "truly serious".

"The ability to identify, isolate and track contacts will help determine whether or not to continue trying to reopen the US. I am worried if some states, regions, or cities ignore the conditions.

He said the United States has made great strides in increasing testing and the number of infections has "fallen rapidly".
