The coronavirus seems to be accelerating in countries across the world with Australia the latest to announce a record number of daily cases – 723.

The world’s two worst-affected countries – the United States and Brazil – have also reported new highs for coronavirus deaths and cases. In the US the death toll has surpassed 150,000, with Florida, California and Texas among a number of states reporting record daily fatalities.

More than 16.8 million people around the world have been diagnosed with the new coronavirus. Some 9.9 million patients have recovered, and nearly 663,000 have died, according to data from Johns Hopkins University.

03:30 GMT – ‘Today is not a good day’: Australia reports number of cases

Australia has reported the highest number of confirmed cases since the coronavirus pandemic began.

The state of Victoria is the worst-hit with outbreaks centred around care homes and workplaces in Melbourne and its sprawling suburbs.

State authorities reported 723 new cases on Thursday and 13 deaths.

“Today is not a good day,” Victoria state Premier Dan Andrews said in a statement. 

He noted that while most cases in the state were in Melbourne and the suburbs there had been a “significant jump” in cases in regional communities, which warranted additional measures to curb the disease’s spread. 

Mandatory mask wearing extended across the state from Sunday, and in some areas residents will not be allowed to go to other people’s houses or have visitors to their own home.

02:50 GMT – China expert says virus thrives in colder, humid environments

China’s top epidemiologist has been talking to state media.

Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, told local journalists the virus seems to like colder, humid environments.  

He pointed to the country’s COVID-19 outbreaks – from the original source in Wuhan – to Beijing and Dalian, which have been traced to seafood markets or seafood companies.

02:40 GMT – Talks over latest US coronavirus relief package stalled as clock ticks

It seems talks between United States congressional leaders and the White House on a next round of coronavirus spending have stalled as the clock ticks down on measures that banned evictions and boosted unemployment benefit payments.

Treasury Secretary Steven Mnuchin has suggested a short-term extension for those programmes, but Democrats have rejected the idea.

Al Jazeera’s William Roberts has been following the negotiations. You can read his story here. 

02:10 GMT – Pelosi to US Congress: Mask up!

US House Speaker Nancy Pelosi says members and staff in the House of Representatives must wear masks while the coronavirus pandemic continues.

The move came after Republican Representative Louie Gohmert, who refused to wear a mask, revealed he had tested positive for COVID-19, leading at least three of his colleagues to say they would self-quarantine.

Pelosi warned that she had the authority to ask the House sergeant at arms to remove a member from the floor for violating decorum, and “the chair views the failure to wear a mask as a serious breach of decorum.”

Members will be allowed to remove their masks when addressing the chamber.

01:50 GMT – Guatemala buries dozens of unidentified COVID-19 fatalities

Guatemalan hospital officials say they’ve had to bury dozens of COVID-19 victims who have never been identified, according to AP news agency.

The agency says workers at one of the country’s largest public hospitals have begun photographing patients who arrive alone and too ill to give their personal details. Those who die without being identified are placed in body bags with transparent windows over their faces in case relatives come looking for them.

Officials says protocols to rapidly bury the dead during a pandemic only make the situation more difficult.

Guatemala has confirmed more than 47,000 confirmed infections and more 1,800 deaths nationwide. 

01:35 GMT – US records a coronavirus death every minute as total surpasses 150,000

One person in the United States died about every minute from COVID-19 as the national death toll surpassed 150,000, the highest in the world, according to Reuters.

US coronavirus deaths are rising at their fastest rate in two months and have increased by 10,000 in the past 11 days.

01:20 GMT – Mainland China reports 105 new COVID-19 cases, including 96 in Xinjiang

The National Health Commission says 96 of the new cases were confirmed in the far western region of Xinjiang, while five were in the northeastern province of Liaoning, one in Beijing, and three imported cases.

00:45 GMT – Vietnam outbreak that started in Danang continues to grow

Vietnam’s health ministry has reported an additional nine cases of coronavirus, as an outbreak that started in the popular tourist town of Danang continues to expand.

00:00 GMT – Brazil reports record numbers of coronavirus deaths, cases 

Brazil’s Health Ministry has just confirmed a record of 1,595 daily deaths from coronavirus. Taken on a weekly basis (7,677 this week), deaths are also at their highest since the pandemic began.

The authorities also reported a record number of cases for a single day (69,074), partly as a result of working through a backlog of previously unregistered cases.

Despite the accelerating pandemic, the government of President Jair Bolsonaro has moved to ease restrictions to boost the economy, and on Wednesday said a ban on foreign travellers to the country would be lifted.
