Washington ratcheted up tensions over the pandemic by accusing China of trying to steal research into a vaccine, while US President Donald Trump upped the rhetoric, with a colourful phrase that could anger Beijing.
Brazil's Health Ministry registered 14,919 new confirmed cases in the prior 24 hours, taking the total to 233,142, behind the United States, Russia and the United Kingdom. Brazil has done just a fraction of the testing seen in those three countries.
The country — hardest hit by the pandemic in terms of the number of fatalities — has now confirmed a total of 1,466,682 cases, the Baltimore-based school reported.
The Oman News Agency, ONA, quoted the ministry as saying that 22 individuals had died from the virus, and 1,465 patients had recovered.
Infections have been reported in more than 210 countries and territories since the first cases were identified in China in December 2019. The United States is the worst hit with 88,719 deaths and 1.49 million cases as of 15.17GMT (UAE time 19.17) on Monday.
The Office for National Statistics figures tallied all fatalities in which COVID-19 was suspected or mentioned on death certificates up to May 29. The total of 49,989 is higher than the government's latest daily figure of 40,597, which includes only the deaths of patients who tested positive for coronavirus.
In the United States, the worst-hit country, the death toll stood at 47,178 with 856,209 infections. At least 77,963 patients have recovered. Italy is the next most affected country with 25,549 deaths and 189,973 confirmed infections.
COVID-19 fatalities mounted in the United States and hard-hit Western Europe countries, but fresh data on rising infections and deaths in Africa showed the virus is leaving no continent uscathed in its global march.
Sunday's figure came on the same day that New York Governor Andrew Cuomo said the epidemic in his hardest-hit state is "past the high point." The 24-hour tally in the United States had exceeded 2,500 on Wednesday, Johns Hopkins data showed.
The crisis has left tens of millions unemployed in the US, which has by far the highest number of confirmed COVID-19 fatalities. Forecasts warn of the worst global recession in a century, with demand for goods gutted, and travel and tourism hammered.
