The number of people infected by the novel coronavirus worldwide topped 2 million on Wednesday, led by a surging number of confirmed cases in the United States, in the midst of an escalating battle between President Donald Trump and the World Health Organization.

The outbreak’s center is now in the U.S., as Asia and parts of Europe relax social distancing rules. Still, America’s sluggish testing per capita has stoked a debate over when its economy can normalize from stay-at-home rules that have sparked a deep recession.

Trump said late Wednesday the country was ready to reopen in parts, citing declining case numbers in major metros and noting some states have fewer than 1,000 cases.

The White House coronavirus task force is working on guidelines to reopen the economy in phases, which will be presented to all 50 governors Thursday, Vice President Mike Pence said.

But the New York-New Jersey metro area hasn’t seen a definitive trend just yet, officials said.

In hard-hit New York, Governor Andrew Cuomo on Wednesday ordered that all residents must wear face coverings in public, as confirmed cases and deaths in the state continue to climb. The Big Apple is a global epicenter of the U.S. outbreak, where confirmed COVID-19 diagnoses have surpassed 600,000 and the domestic death count has topped 25,000.

Amid a polarizing debate over when the world’s largest economy will relax strict stay at home orders that have shuttered businesses and left over 16 million unemployed, President Donald Trump has gone on the offensive against the World Health Organization, announcing late Tuesday that the U.S. would cut its contribution to the agency.

Trump has fended off accusations that his administration was slow to recognize the gravity of the crisis. Meanwhile, the president has faulted the WHO for fumbling its response, a critique that Director General Director General Tedros Adhanom Ghebreyesus was forced to address on Wednesday.

“We regret the decision of the president of the United States to order a halt in the funding to the WHO," Ghebreyesus told a daily press conference — calling the pathogen a “dangerous enemy” that required all parties to work together in order to defeat.

The U.S. is by far the WHO’s top contributor, accounting for 15% of its budget, and Trump has recently stepped up his critique that the organization mishandled the crisis in an effort to placate China, where the virus originated. Early in the crisis, the WHO was critical of Trump’s proposed travel ban, and was slow to declare the outbreak a pandemic.

“The WHO pushed China’s misinformation about the virus,” the president said on Tuesday. Trump argued that the organization “willingly took China’s assurances at face value, and they willingly took it at face value and defended the actions of the Chinese government even while praising China for its so-called transparency.”

Chinese and European officials have attempted to persuade Trump to continue providing funding, while Bill Gates called the move by Trump “dangerous.”

Trump battles America’s governors

In recent days, Trump has asserted the federal government’s primacy over the U.S. economy, but on Tuesday backed away from a claim that he had total authority to reopen the government. Governors in large coastal states have formed a coalition to outline plans about when states can relax stay at home orders that have closed businesses and put millions on the dole.

Data on Wednesday revealed the damage wrought by the crisis, as the Commerce Department on reported an 8.7% plunge in retail sales in March.
