The number of novel coronavirus infections in the US has risen rapidly in the past week, surpassing both China and Italy to become the country with the most confirmed cases.
The US figures have more than quadrupled over the past seven days.
As of early Monday morning on March 23, the US had at least 34,000 cases of the virus, according to CNN's figures. There were only 414 deaths registered from Covid-19 across the country and many states still hadn't reported a fatality.
One week later, and there are more than 139,000 confirmed cases, according to CNN's figures -- over four times the number reported just a week ago.
Deaths has risen even faster. There have now been over 2,400 fatalities from the coronavirus, with Wyoming and Hawaii the only states yet to report a fatality.
Dr Anthony Fauci, a member of the White House's coronavirus task force, said Sunday it was "entirely conceivable" that the number of infections could rise to one million.
President Donald Trump said Sunday that if the numbers of deaths could be contained to 100,000 or less, "we would have done a very good job."
