The scale of the data is simply staggering. Peking University estimates 900 million Chinese people have now been infected with COVID, representing about two thirds of the population. The other mind-blowing figure in today’s story by Burnet Institute epidemiologist Michael Toole is that during the Lunar New Year period – which starts this weekend – people in China will make up to an estimated two billion trips around the country.
He explains this inland travel could still have implications for those of us outside China. That’s even though Australia is among the countries now requiring travellers from there to test for COVID before they depart for our shores.
Firstly, it’s possible travellers will transmit the virus to remote parts of China where it could fester and mutate into a more transmissible variant. And then there is a potential people will travel to Australia via other countries while infected.
We should be prepared for the pandemic to shift again, writes Professor Toole. And right now, we are not.

China have been overestimated or deaths have been underestimated. Whatever the case, China’s massive COVID surge and expected Lunar New Year travel could raise risks for other countries.
