04:35 GMT – Doubts over AirAsia’s ability to continue in business

Auditors for AirAsia, Southeast Asia’s biggest low cost carrier, have warned there is risk to the airline’s ability to continue in business as a result of the coronavirus pandemic.

The airline has said it is looking to raise more capital. On Monday, it posted its biggest ever first quarter loss – 803.3 million ringgit ($103 million).

AirAsia was bought over by Malaysian tycoon and former music industry executive Tony Fernandes nearly 20 years ago and turned into a low cost airline inspired by EasyJet in the UK. Its shares were suspended on Wednesday.

AirAsia, with 255 planes and over 20000 employees, is in deep trouble.

Auditors say its ability to continue as a going concern may be in “significant doubt.” https://t.co/6UlG9pgR0L

Panic buying has hit supermarkets in Melbourne and Victoria again, ahead of the six-week lockdown that comes into force in a few hours time.

Woolworths – Australia’s biggest grocery chain – has already reinstated buying limits for basics including pasta, sugar and toilet paper.

Disappointing.

There is absolutely no need to rush out to the supermarket.https://t.co/kFonAZbgVD

03:35 GMT – Australia to consider limiting citizen and resident returns

Australia’s coronavirus emergency cabinet is to consider limiting the number of citizens and residents allowed to return to the country, following a spike in cases in Melbourne. 

Health authorities say many of the cases have been traced back to hotels where people who had returned from overseas were being quarantined.

Prime Minister Scott Morrison says there are no plans to reimpose coronavirus restrictions across the country after the Melbourne outbreak prompted the closure of state borders and a citywide lockdown.

Many are asking where the lockdown areas end. See map below.

Stage 3 restrictions will affect Melbourne and Mitchell Shire, for six weeks.

This is to #FlattenTheCurve once more, here in Victoria.

03:05 GMT – Scientists warn of coronavirus carries risk of brain damage

Scientists at University College London are warning of the risk of brain damage from coronavirus.

UCL researchers studied 43 patients who suffered either temporary brain dysfunction, stroke, nerve damage or other serious effects on their brain, and say the disease can lead to severe neurological complications including psychosis and delirium.

The study found nine of the patients were diagnosed with a rare condition called acute disseminated encephalomyelitis (ADEM), which is usually seen in children and can be triggered by viral infections.

The team said they would only usually see about one adult patient with ADEM a month, but it had risen to a “concerning” one a week while they were conducting the study.

“Given the disease has only been around for a matter of months, we might not yet know what long-term danage COVID-19 can cause,” said Ross Paterson, who co-led the study. “Doctors need to be aware of possible neurological effects, as early diagnosis can improve patient outcomes.”

02:15 GMT – New Zealand to charge man with coronavirus who escaped quarantine

New Zealand is to prosecute a 32-year-old man who briefly absconded from an isolation facility after testing positive for the virus.

The man was in quarantine in Auckland after arriving from Delhi on July 3. He escaped through a fenced area of the hotel and and visited a supermarket before returning to the facility.

“We take any breach of the COVID-19 rules very seriously,” said Commodore Darryn Webb, the head of managed isolation and quarantine. “Willfully leaving our facilities will not be tolerated, and the appropriate action will be taken.”
