After hearing how scary COVID-19 was for almost three years, 25-year-old Karen Huang felt "a little bit relieved" when she tested positive for the virus in mid-December.

"Just like others, I had been wondering when it would be my turn to get COVID," said Ms Huang from Guangzhou. 

Only a week before her infection, China announced it would ease COVID-19 restrictions in response to nationwide anti-lockdown protests since November.

Watching news about the end of COVID-zero restrictions, Ms Huang predicted there could be an outbreak in the coming weeks.

To protect herself, she decided to get the new inhalable COVID-19 vaccine booster, which was first launched in China in October, was tailored to the Omicron variant and had been recently introduced to her neighbourhood.

As the local community already paused daily mass testing, she decided to go through a PCR test the day before vaccination.

To her surprise, she tested positive despite having no symptoms.

Unlike those who tested positive during China's COVID-zero period, Ms Huang could choose to quarantine at home rather than being taken to a quarantine hospital.

Her neighbours also did not need to go into lockdown because of a positive case in the building.

Just like hundreds of thousands of Australians who went through a mass Omicron outbreak in January 2022, Ms Huang and her friends were also caught up in China's transition from COVID-zero to learning to live with the virus.

However, the two countries have gone through different pathways during their transition to post-pandemic life.

The parallels between Australia and China’s COVID opening

Australia announced it would abandon COVID-zero measures at the end of 2021 and turned to living with COVID, after the highly transmissible Omicron variant spread through the country.

Following the switch, Australia recorded tens of thousands of COVID-19 daily cases over December and into January 2022, with the elderly population strongly hit by the variant.

By mid-January, the aged care peak body said more than half of all Australian residential aged care facilities were experiencing COVID-19 outbreaks but only one-third of elderly residents had received a booster around that time.

Federal and state governments were under strong criticism for failing to provide adequate support for aged care homes and for slow COVID-19 vaccine booster rollouts.

The Morrison government was also criticised for failing to handle the COVID-19 testing system, as the national shortage of rapid antigen tests continued for weeks, leaving thousands of people unable to claim sick leave despite COVID-19 infections.

In New South Wales — one of the states most hit by the Omicron variant — hospitals were overwhelmed with COVID-19 patients while facing a huge staff shortage.

Fast forward to today, and what happened in Australia in January is eerily similar to China's current experience with its COVID-19 transition, with both countries opening amid widespread Omicron outbreaks.

Videos circulated on Chinese social media showed hospitals packed with COVID-19 patients, while funeral homes in several cities were reported to be full since the outbreak began in early December.

Local pharmacies were reported to run out of flu medication, which sparked some Chinese Australians to post medicines to families back home.

Yanzhong Huang, senior fellow for global health at the Council on Foreign Relations, said it was "very likely 30 to 40 per cent of the population" had been infected with COVID-19 in China so far.

Dr Huang said most of these cases were symptomatic, with a large proportion of the elderly population developing severe symptoms.

He also said while China's overall vaccination rate was more than 90 per cent, there had been concerns about China's domestic vaccines being ineffective in preventing Omicron infection.

"And secondly, most of them were vaccinated more than six months ago, so the antibody level has dropped into a level that's very likely undetectable," Dr Huang told ABC NewsRadio.

Similar to Australia's aged care crisis during the Omicron outbreak, China also struggled to effectively roll out vaccination in the elderly population.

Government data in early December showed only 42.3 per cent of people aged 80 and above had COVID-19 booster shots, while only two-thirds of those were fully vaccinated.

But there are also some key differences between Australia's and China's experiences.

China faces a unique set of challenges

Hui Yang, adjunct associate professor of public health at Monash University, said it was common to see a medical system — whether Australia's or China's — suddenly become overloaded when it was hit by an outbreak.

But Professor Yang said people should believe in resilience from both medical and policy systems to respond to the crisis.

He noted China did have some unique challenges compared with Australia when it came to the Omicron outbreak, including its huge population base, complicated management structures and inadequate medical resources per capita.

"China's medical system builds its base on hospitals, while general practice and primary care are the foundation of Australia's medical system," Professor Yang said.

"The two countries also have huge distinctions in the quantity, quality and allocation of nursing resources."

Dr Amesh Adalja, senior scholar and infectious diseases expert at Johns Hopkins Center for Health Security in Pittsburgh, also noted China had a low ICU capacity, which could lead to "a high level of severe disease and death".

"The thing is, this was completely preventable. They've had three years or so to actually build resiliency into the population," said Dr Amesh Adalja.

"However, they were unable to do so — or they chose not to do so — and not to use potent vaccines from the Western world.

"And that's left them in this situation where they have really little choice left, based upon what's happened," Dr Adalja told ABC NewsRadio.
