Up to 1.6 million people in NSW could be hit by the first wave of a statewide coronavirus outbreak, health authorities warn, with up to 80,000 people likely to require intensive care simultaneously.
Chief health officer Dr Kerry Chant says preparations are underway for 20 per cent of the state’s eight million residents to catch COVID-19.
Dr Chant expects every person who becomes ill will pass it on to 2.68 others on average – although this could be reduced through self-isolation, social distancing and handwashing.
“We’re anticipating 20 per cent of the population in the first wave to be affected,” Dr Chant told a NSW budget estimates hearing on Thursday.
She said forecasts showed five per cent of residents affected by coronavirus – or up to 80,000 people – would require intensive care.
NSW now has 78 confirmed cases of COVID-19 including a barista who worked at Pastadelli in Wahroonga on Sydney’s upper north shore.
The staff member worked at the cafe on 14 days between February 19 and March 8.
Oscar-winning actor Tom Hanks and musician wife Rita Wilson were on Thursday confirmed to be infected with coronavirus.
Wilson last Saturday performed in front of 207 people at the Sydney Opera House.
The iconic venue is getting in touch with anyone, including patrons and staff, who came into contact with the couple during the performance.
Of the 78 cases in NSW, 34 were likely acquired overseas, 32 had contact with a confirmed case, 10 are under investigation and two have no known source.
The World Health Organisation overnight declared the global crisis a pandemic, sounding the alarm about mounting infection rates and slow government responses.
Dr Chant said NSW Health was planning to double the state’s intensive care unit capacity and double the availability of ventilators.
The response is in relation to both COVID-19 and the start of the flu season.
“We think doubling is prudent in the first stage,” Dr Chant said.
“But if we have to do more, that’s fine.”
Authorities have not yet finalised plans for so-called “drive-through” coronavirus testing sites.
Dr Chant implored anyone flying into NSW from overseas – not solely from banned countries China, South Korea, Iran and Italy – to distance themselves.
“Practically, you should attempt to keep … 1.5 metres between yourself and others, avoid crowds, mass gatherings,” she said.
Premier Gladys Berejiklian on Friday will meet with state and territory counterparts at COAG to discuss the possibility of mass closures of schools, universities and large events.
She encouraged residents to stay home if they felt ill.
“There’s no need to panic, to massively change what you’re doing, but it’s not business as usual,” Ms Berejiklian told reporters.

NSW Health on Wednesday said COVID-19 clinics will be opened in all local health districts to diagnose patients with symptoms.
