Hunter, NSW COVID-19 cases rise as current wave grows by 83 per cent

There were 2354 cases recorded across the district in the week ending November 12, up from 1280 the week prior. There were 39 people within the region hospitalised with COVID-19 - including four that required intensive care - and four deaths.

To date this year, Hunter New England has recorded 376,406 positive cases of COVID-19.

The latest NSW Respiratory Surveillance Report shows case numbers across the state have increased by almost 53 per cent, with 22,672 people diagnosed with COVID-19.

The seven-day rolling average of associated daily hospital admissions increased to an average of 63, up from 55 the week prior.

There were 440 people with COVID-19 admitted to hospital, and 40 in intensive care. Emergency department presentations for coronaviruses that required an admission jumped to 248 from 169. The number of people in hospital with COVID-19 now sits at 1,055, compared to 857 in the week before.

PCR testing for COVID-19 also increased by 17.7 per cent within that time.

It comes as researchers from the University of Tasmania and Deakin University found more than half a million Australians could experience long COVID, with 110,000 suffering "significant impacts". The researchers used modelling to estimate how many people may have long COVID symptoms in early December.

They have called on the federal government to increase data gathering and surveillance, as the nation's peak body for general practitioners calls for extra support to care for patients.

Long COVID is characterised by long-term health issues including extreme fatigue, which usually arise three months from the onset, with symptoms lasting at least two months.

The World Health Organisation estimates 10-to-20 per cent of people with the virus will experience long COVID.

The study's models suggest at least 160,000 Australians will likely be experiencing long COVID symptoms in early December and, for more than 35,000 people, their symptoms will "significantly limit" their activities.

The estimates increased to more than 500,000 and more than 110,000 respectively when researchers made adjustments based on additional work by the Australian National University.

"It is likely that several tens of thousands of Australian adults will be unable to work in December due to long COVID," report lead author, Professor Martin Hensher, said. "This will not only have a detrimental impact on the health and wellbeing of our country, but many flow-on effects to the economy."

He said Australia was an outlier among similar countries in not having instituted large-scale national surveys about long COVID.

The study made several recommendations, including greater surveillance of long COVID via regular Australian Bureau of Statistics and Australian Institute of Health and Welfare surveys.

More than 10.5 million Australians have contracted COVID-19. In the week to November 9, 54,661 new cases were reported nationwide.

Doctors told a federal parliamentary inquiry last month that long COVID clinics across the country were being inundated with requests and waitlists are increasing.

President of the Royal Australian College of General Practitioners, Professor Karen Price, wants greater education.

"One of the challenges we face is poor patient awareness of long COVID and lack of access to medical and allied health appointments, not to mention the possibility of substantial out-of-pocket fees in accessing multidisciplinary care," she said.

"Patients are reporting problems navigating the health system to get proper long COVID assessment, diagnosis, and appropriate treatment and that must change. There are not enough specialist long COVID clinics, especially in rural and remote areas, and those clinics that are up and running can't meet demand."
