It comes after some states in America continue plans to ease the lockdown.
Reports reveal Arizona, Florida, Oklahoma, Oregon and Texas recorded sharp increases in new cases following all-time highs in the same states last week.
Nevada also announced the largest single-day tally for the state so far, confirming another increase from a previous high on May 23rd.
Statistics also show an upward curve in hospitals.
COVID-19 patients have taken up large capacity in certain centre’s, a hospital representative at Arizona’s Tucson Medical Center revealed the true scale that the threat new cases pose.
They revealed on Monday that just a single intensive care unit bed designated for COVID-19 patients was available, whilst the other 19 had been taken.
Dr Steve Oscherwitz, an infectious disease expert at the hospital explained that the lack of resources could present challenges for patients who need intensive care.
Mr Oscherwitz said: “ICU to be expanded, hopefully, in coming days.”
“Not sure where people needing ICU care will be able to go since most AZ [Arizona] hospitals are pretty full now.”
Health officials expect the further outbreak has formed from the decision from some states to reopen aspects of society in the next phase of easing lockdown.

Epidemiologists suggest that plans to continue reopening could result in more infections.
Wafaa El-Sadr, professor of epidemiology at Columbia University said: “The worrisome thing for me is that there’s a lot of fatigue in the population overall.
“People feel they have done distancing and they are thirsting to get outside and connect with each other.
“If this surge requires us taking a step back, how do we convince people to do that?
I feel we’ve made five steps forward and now maybe one step back.”
President Trump announced at a daily briefing in April that lockdown would start to be eased and the Presidents believed the people of America thought the same.
Trump said at the time: “America wants to be open and Americans want to be open.
“A national shutdown is not a sustainable long-term solution.”
He suggested that maintaining the lockdown could have long-term public health effects.
Trump warned of a “sharp increase” in drug abuse, alcohol abuse, heart disease and physical and mental problems.
Ira Longini, professor of biostatistics at the University of Florida also suggested numbers will continue to rise if states continue to ease lockdown.
Miss Longini said: “All the modelling has shown if you reopen without extensive testing and contract tracing, you’ll see an increase in the epidemic,
“That activity is not happening in an organised way in Florida, it’s haphazard.”
