Aussies who feel unwell have been urged to isolate and stay home as a fresh wave of Covid-19 runs rampant on one side of the country. 

Cases of the Omicron subvariants have skyrocketed in Western Australia in recent weeks with an average 75 infected patients admitted to hospital daily.

Recent surveillance data, including wastewater analysis and reported cases, has sparked fears that frontline healthcare workers could see hospitalisations climb even higher.

Authorities have warned anyone with cold or flu-like symptoms to stay at home and to wear masks in crowded public settings with the wave’s peak set to fall during the Christmas holidays.

Even those experiencing mild symptoms are encouraged to self-isolate as seemingly minor cases can lead to long Covid, which may last for months.

West Australians can also protect themselves by rolling up their sleeves for the new Pfizer JN.1 booster vaccine released earlier this month.

‘COVID-19 has changed a lot over the past year within Australia and throughout the world,’ WA Health communicable diseases director Dr Paul Armstrong said.

‘The new vaccine is expected to provide increased protection against the Omicron subvariants which are now circulating in WA.’

Some Aussies are at greater risk of severe illness from the virus due to a weakened immune symptoms or repeated exposure.

‘Covid can cause life-threatening complications, particularly among older adults and people with underlying medical conditions,’ Dr Armstrong said.

‘With Christmas just around the corner, people may be out socialising with family and friends so there is the potential for infection to spread more easily compared to other times of the year.

‘The best way to protect yourself and those around you from Covid is to stay home if you are unwell, cover coughs and sneezes, wash or sanitise your hands often, consider wearing a mask in crowded indoor or high-risk settings, and get a booster vaccination.’

The warning comes after yet another new Covid variant spreading around the world recently reached Australia’s shores.

First detected in Germany in June, the ‘potentially more infectious’ XEC strain is a descendant of the Omicron Covid strain and a recombinant variant of KS.1.1 and KP.3.3.
