At least 10,503 new cases of coronavirus and 615 new deaths were reported in the last 24 hours in Brazil, according to the country's health minister.
There are now at least 125,218 cases of Covid-19 in the country and at least 8,536 people have died from the disease.
Brazil currently has the highest number of coronavirus cases in Latin America while Brazilian President Jair Bolsonaro has faced criticism for downplaying the threat of the virus.
Bolsonaro has repeatedly attended large political rallies calling for an end to quarantine measures in the country.

Researchers report "unprecedented cluster" of inflammatory problems in children amid pandemic
From CNN’s Arman Azad
Researchers in the UK say they have seen an “unprecedented cluster” of eight children with rare inflammatory problems amid the coronavirus pandemic.
The cases, they said, bear resemblance to a severe form of Kawasaki disease – a rare condition that causes inflammation in the walls of the arteries and can limit blood flow to the heart.
All of the children were previously fit and well, the researchers said in a study published Wednesday.
Five of the children received mechanical ventilation through a tube in their windpipes, and one was put on an ECMO machine – a device that takes over for the heart and lungs.
Seven of the children survived, and one died from a stroke. Four of the children had known exposure to coronavirus, and two eventually tested positive. Six of the children were of Afro-Caribbean descent, and five were boys.
In the study, published in the medical journal The Lancet, the researchers said the case cluster formed the basis of a national alert. In late April, Britain’s National Health Service sent an “urgent alert” to doctors saying they had seen cases of atypical Kawasaki disease that could be linked to coronavirus.
As their study went to press, the researchers said they had treated more than 20 children with similar signs. The first 10 of these children tested positive for coronavirus antibodies – including the eight who made up the original “cluster” of cases. That suggests they had been exposed to the virus in the past, even if their diagnostic test came back negative at the time.
“We suggest that this clinical picture represents a new phenomenon affecting previously asymptomatic children with SARS-CoV-2 infection manifesting as a hyperinflammatory syndrome with multiorgan involvement similar to Kawasaki disease shock syndrome,” the researchers wrote.
Separately, the New York State Department of Health issued an advisory to healthcare providers about a similar syndrome. The state said that as of May 5, it had received 64 potential cases of the condition, called Pediatric Multi-System Inflammatory Syndrome Associated with COVID-19.
“The inflammatory syndrome has features which overlap with Kawasaki disease and toxic shock syndrome and may occur days to weeks after acute COVID-19 illness. It can include persistent fever, abdominal symptoms, rash, and even cardiovascular symptoms requiring intensive care,” the New York health department said in a statement.

Trump says China could have stopped pandemic after initially praising their efforts
From CNN's Samantha Beech in Atlanta
US President Trump has again leveled accusations that China could have stopped the global coronavirus pandemic, calling the spread "the worst attack we've ever had on our country."
Speaking from the Oval Office today, the President went on to say, "This is worse than Pearl Harbor. This is worse than the World Trade Center."
What we know: So far, more than 71,000 people in America have died from coronavirus. In comparison, more than 2,000 Americans were killed in the Pearl Harbor bombings during World War II. On September 11, 2001, a total of 2,977 people were killed in New York City, Washington, DC and outside of Shanksville, Pennsylvania.
But while Pearl Harbor and 9/11 were direct and targeted attacks on the United States, the coronavirus pandemic is impacting countries all over the world, including in China. As of today, Johns Hopkins University puts China's death toll from the virus at 4,637.
There's never been an attack like this," Trump said today in the Oval.
The President added: "And it should have never happened. Could have been stopped at the source. Could have been stopped in China. It should have been stopped right at the source. And it wasn't."
In recent days, Trump and Secretary of State Mike Pompeo have doubled down on the assertion that the virus originated from a laboratory in the central Chinese city of Wuhan, where the outbreak was first detected last December.
The claim has unsurprisingly drawn fierce rebuttal from the Chinese government, which described the accusation as "smear" intended to bolster Trump's reelection chances.
Intelligence shared among the Five Eyes network — an alliance between United States and the UK, Australia, New Zealand and Canada — also reportedly appears to contradict the Trump administration's assertion.
Trump's recent displeasure with China are a far cry from his past statements on the nation and its leader, Xi Jinping, whom he earlier praised for his transparency and management of the outbreak.
As recently has last month, Trump was touting his administration's trade deal with China during a White House coronavirus task force briefing. The president said the relationship with China is "very good" and the "biggest communication" is between himself and President Xi.
"So, look, the relationship with China is a good one, and my relationship with him is, you know, really good," Trump said on April 1.

The number of coronavirus patients in intensive care units in France has continued to steadily decline since April 9, data from the French Ministry of Health shows.
There are currently 3,147 Covid-19 patients in ICU in France, down by 283 from the day before, the ministry said on Wednesday.
A total of 23,983 people are hospitalized with coronavirus in France, which is down by 792 from the day before.

Study finds blood thinners may help patients with severe Covid-19 infections
From CNN's Maggie Fox
Blood thinning drugs may help save some patients worst affected by coronavirus, doctors reported Wednesday.
Their findings could point a way to help the virus-related issue of blood clots throughout the body. The team at Mount Sinai Hospital says it is now running experiments to see which anticoagulants may work best, and at which doses.
“Our findings suggest that systemic anticoagulants may be associated with improved outcomes among patients hospitalized with Covid-19,” they wrote in their report, published in the Journal of the American College of Cardiology.
Dr. Valentin Fuster, director of Mount Sinai Heart and physician-in-chief of the Mount Sinai Hospital, and colleagues looked at more than 2,700 patients treated at Mount Sinai in New York City, which has been hit hard by coronavirus. Starting in March, some patients were given anti-clotting drugs based on bedside decisions made by doctors.
The team started taking a systematic look at whether the drugs made a difference. They did, especially for patients who were put on ventilators to help them breathe.
They found 29% of patients on ventilators who were given blood thinners died, compared to 63% of patients on ventilators who were not given blood thinners.
“The patients who received anticoagulants did better than those who didn’t,” Fuster told CNN.
The findings are not clear-cut enough yet to make solid recommendations. The team noted that patients who were already severely ill were more likely to be given the blood thinners.
The researchers did not find that the patients who got blood thinners were significantly more likely to have bleeding problems – one of the risks of the drugs.
