Dr Chant has described the revelation as a “a salient lesson” that the virus can affect anyone, regardless of their age.
“There are 19 people admitted to hospital at the moment with COVID under the age of 55, and of those, eight are under the age of 35,” Dr Chant said.
“Of the 16 people in ICU, one is in their teens.
“I think it is a salient lesson that COVID can impact across all age groups.”
Dr Chant said that although the teen is in intensive care, they are not on a ventilator.
The remaining people in the ICU include one person in their 20s, one in their 30s, one in their 40s, three in their 50s, six in their 60s, two in their 70s, one in their 80s.
None of those being treated for the Delta variant in hospital have been fully vaccinated, Dr Kerry Chant has revealed.
Of the 47 people admitted to hospital, 37 are unvaccinated.
Four have received the first dose of AstraZeneca vaccine and one has received first dose of Pfizer.
Five of the cases have both doses of the Pfizer, however they are all residents from the Summit Care home who have been admitted for observation and monitoring despite being asymptomatic.
Dr Chant said the statistics reinforce the importance of vaccination in tackling the virus.
“Please go and get vaccinated. If you have access, according to the eligibility checker for your vaccine, make that appointment now, and if you’ve had your first dose of AstraZeneca, go and get your second dose,” she said.
NSW Premier Gladys Berejiklian said that young people getting seriously ill with COVID-19 is a “phenomena we have not seen before” in Australia.
“We have a number of young people in ICU at the moment and that is a phenomena we are not seen before in terms of the broader population,” she said.
“We all have to work together. The length of this lockdown is up to each and every one of us.”
