The number of deaths in the U.S. totaled more than 60,000 as of Wednesday evening, according to NBC News' tally, while the global death toll climbed over 226,000, according to Johns Hopkins University.
The growing U.S. death toll hasn't prevented some states from relaxing their lockdowns, including Florida, which announced it would begin lifting stay-at-home orders on Monday.
Meanwhile, Dr. Anthony Fauci, the head of the National Institutes of Allergy and Infectious Diseases, said Wednesday that an experimental drug for the coronavirus has a proven benefit.
"The data shows that remdesivir has a clear-cut, significant, positive effect in diminishing the time to recovery," Fauci said at the White House on Wednesday.

New polio outbreak in Niger after vaccination suspended during COVID-19 pandemic
Niger has been struck by a new outbreak of polio, following the suspension of immunization activities during the COVID-19 pandemic, the World Health Organization said Wednesday.
The United Nations health agency reported that two children were infected by the highly infectious, water-borne disease and that one was paralyzed.
The outbreak was sparked by a mutated virus that originated in the vaccine and was not connected to a previous polio epidemic Niger stopped last year, WHO said, in a statement last week.
"The poliovirus will inevitably continue to circulate and may paralyze more children as no high-quality immunization campaigns can be conducted in a timely manner," said Pascal Mkanda, WHO's coordinator of polio eradication in Africa.
Senior Chinese official challenges Trump over coronavirus response, says U.S. wasted weeks
A senior Chinese government official challenged President Donald Trump's handling of the coronavirus outbreak in the U.S., accusing him of wasting weeks after the threat posed by the virus first became apparent.
In a wide-ranging interview with NBC News conducted in Mandarin on Tuesday, the official, Executive Vice Foreign Minister Le Yucheng, also hit back at the politicization of the virus.
Le, a rising star within the country's political establishment, rejected claims that China had covered up the initial outbreak or that it should be held financially liable for COVID-19. Instead, he termed the virus a "natural disaster" and called for greater cooperation and an end to accusations.
'Very concrete' risk of second outbreak, Italy's prime minister says
Italian Prime Minister Giuseppe Conte said the risk of a second coronavirus outbreak was "very concrete" as the country emerges from Europe's longest lockdown.
“We can’t afford to have an out of control situation," he told reporters during his visit to the city of Lodi in northern Lombardy, the hardest-hit region by the outbreak. "This is the time to act with reason, with prudence.”
On Sunday, Conte said Italy — the hardest-hit European country with more than 27,000 deaths — was looking ahead to a second phase of the crisis in which it will attempt to restart the economy without triggering a second wave of the disease, with manufacturers, construction companies and some wholesalers allowed to re-open from May 4.

Chinese official contradicts Pompeo on coronavirus cooperation
China is open, transparent and responsible in its COVID-19 response, said the country's foreign ministry spokesperson Wednesday in response to a tweet from U.S. Secretary of State Mike Pompeo that accused China of not cooperating in the search for the origins of the coronavirus pandemic.
Chinese Foreign Ministry spokeswoman Hua Chunying re-tweeted Pompeo's message and said two U.S. experts were in China on the joint mission between the World Health Organization and China in late January. "Why not ask U.S. experts to locate when the virus first started in the U.S.? American people need answers. The world also has right to know," she added.
After beating coronavirus, Britain's PM Johnson announces birth of son
Weeks after the British prime minister was in intensive care with a serious case of the coronavirus, Boris Johnson and his fiancée Carrie Symonds announced the birth of their baby son on Wednesday.
"The Prime Minister and Ms Symonds are delighted to announce the birth of a healthy baby boy at a London hospital earlier this morning and would like to thank the fantastic NHS maternity team," a government spokesman said.
Johnson, 55, suffered serious symptoms after being infected with COVID-19 last month. He left intensive care less than three weeks ago, thanking staff at the country's publicly funded National Health Service "for saving my life." Symonds, 32, an environmental activist and former official in Johnson's ruling Conservative Party, also suffered symptoms but was never tested.
Spain — one of Europe's worst hit countries — aims for return to normal in June
Spain announced a four-phase plan to lift one of the toughest coronavirus lockdowns in Europe and return to normality by the end of June.
Prime Minister Pedro Sanchez said the lifting of the restrictions that have halted public life since March 14 and nearly paralysed the economy, will begin on May 4 and vary from province to province. During the initial phase, hairdressers and other businesses that operate via appointment will open, while restaurants will be able to offer takeaway services.
In the next stage, envisaged to begin on May 11 for most of Spain, bars will reopen their terraces but will be limited to a third of their capacity. Remote working will be recommended where possible until reaching the last phase of the plan towards the end of June, when beaches would also be able to reopen with the support of local authorities.
Trump administration asks intelligence agencies to find out whether China, WHO hid info on coronavirus pandemic
The White House has ordered intelligence agencies to comb through communications intercepts, human source reporting, satellite imagery and other data to establish whether China and the World Health Organization initially hid what they knew about the emerging coronavirus pandemic, current and former U.S. officials familiar with the matter told NBC News.
A specific "tasking" seeking information about the outbreak's early days was sent last week to the National Security Agency and the Defense Intelligence Agency, which includes the National Center for Medical Intelligence, an official directly familiar with the matter said. The CIA has received similar instructions, according to current and former officials familiar with the matter.
President Donald Trump appeared to refer to the request at his news conference Monday. "We're doing very serious investigations," Trump said. "We are not happy with that whole situation, because we believe it could have been stopped at the source, it could have been stopped quickly, and it wouldn't have spread all over the world."
