More than 25 million Covid-19 cases have been recorded in the United States since the pandemic began, Johns Hopkins University said Sunday.
The milestone was reached only five days after the US, the world's wealthiest and hardest-hit nation, recorded 400,000 deaths from the disease.
President Joe Biden has made fighting the Covid-19 a priority and is pushing for Congress to approve a $1.9-trillion relief package that would include billions of dollars to boost vaccination rates.
Biden has said he wants 100 million people vaccinated within his first 100 days in office, and he has called for Americans to wear masks for 100 days.
Countries around the world are in a race against time to get their populations inoculated before the coronavirus mutates into a strain that could resist newly approved vaccinations.
After the first Covid-19 case was reported in the US in January 2020 it took until late April for the figure to pass one million. The overall number of cases has followed an almost exponential curve upwards since then.
