From closing borders to moving university classes online, around the world, leaders are taking unprecedented steps to try and ease the spread of the deadly novel coronavirus.
In Australia more than 377 confirmed cases of COVID-19 have been confirmed and five people have died so far.
Australians are likely to have to change their way of life for at least six months as parts of the nation shut down to combat the coronavirus spread, the prime minister has warned.
Scott Morrison's acknowledgement of the timeframe comes as states and territories declare public health emergencies, giving officials greater powers to detain people or restrict movements.
Public health emergencies have been declared in Queensland, Victoria, ACT and South Australia.
Whereas NSW has confirmed 171 cases, the highest of any state or territory in Australia.
Of that number, 37 were confirmed between Sunday and Monday morning, marking the largest number of cases in one day.
Mr Morrison called for the nation to work together to slow the spread of the virus, acknowledging Australians will face greater restrictions as they seek to carry on with their lives.
“This will be a difficult six months. It could be longer. It could be sooner than that,” he told ABC radio on Monday.
It comes as the Deputy Chief Medical Officer Paul Kelly said anywhere between 20 and 60 per cent of Australians will contract the disease.
“It's something in that range,” he said Monday.
“This is an infectious disease ... The death rate is about one per cent, so you can do the maths.”
As The Sydney Morning Herald reported, using those numbers, a worse case scenario could result in as many as 150,000 coronavirus deaths in Australia.
Nationally there has been a ban on mass gathering of more than 500 people and state RSL branches are cancelling upcoming ANZAC Day events.

He said residents will only be permitted to leave their homes for necessary trips such as going to work or the supermarket.
Macron said in televised remarks that the government decided to order the restrictions because people haven’t complied with earlier public health measures and “we are at war”.
Macron added that any violations will be penalised, without elaborating how.
