A doctor has warned parents to be aware of an unusual symptom children with Omicron are now developing.
Young children infected with the latest COVID variant are also presenting with rashes, a London doctor says.
They also are suffering from fatigue, headaches and a loss of appetite - all symptoms which fit with Omicron in adults.
Dr David Lloyd says about 15 per cent of Omicron-positive children he's seen have developed a rash similar to a heat rash.
"We've always had a small cohort of patients with COVID who are getting funny rashes, but up to 15 per cent of the Omicron children are getting an unusual rash," Dr Lloyd said.
"So we're starting to learn a little bit more about the virus and we are starting to look out for it."
Traditionally, the three main symptoms of COVID-19 have been a persistent cough, a high temperature and a loss of taste and smell.
In South Africa, where the Omicron variant was first detected, medical professionals have now said the main symptoms are fatigue, body aches and a headache.
Meanwhile, an emergency national cabinet meeting will be held on Thursday, seeking country-wide consistency on close contact definitions and isolation periods.
Rapid antigen tests - and the crucial question of who pays for them - are also expected to be on the agenda as a number of states and territories join NSW in reporting record-high daily case numbers as the Omicron variant takes hold around the country.
