Washington (CNN) The Biden administration is issuing a new warning that the US could potentially see 100 million Covid-19 infections this fall and winter, as officials publicly stress the need for more funding from Congress to prepare the nation.

The projection of 100 million potential infections is an estimate based on a range of outside models that are being closely tracked by the administration and would include both the fall and winter, a senior administration official told CNN. Officials say this estimate is based on an underlying assumption of no additional resources or extra mitigation measures being taken, including new Covid-19 funding from Congress, or dramatic new variants.

The White House is sharing these estimates as officials renew their push to get Congress to approve additional funding to combat the virus and as the nation approaches a coronavirus death toll of 1 million. Officials have said the White House will commemorate the moment when the US surpasses 1 million deaths from Covid-19.
