Australia had thought of controlling nCoV, but the blockade of 300,000 people in the Melbourne area showed that the war with Covid-19 was not over.

Ring Mayar spends the whole day knocking on doors and houses in the western suburbs of Melbourne, to ask if they have a cough, fever or chills.

"The situation is really difficult," said Maymar, president of the South Sudanese Community Association, Victoria.

Like many other places in the world, nCoV took advantage of the gap in the epidemic control system to flare up again.

According to local media, Australian officials launched an investigation alleging staff at several Melbourne hotels having sex with people who were quarantined, causing a new outbreak.

The new outbreak shows that even though the country is considered "safe" to return to normal life, nCoV can "revive".

Local officials are knocking on every door to call for people to test for nCoV and warn that if they do not comply, all Victoria, Australia's second most populous state will be affected by the new outbreak.

"If someone comes home and asks you to test, the answer should be yes. If you do not do so, we will all be cordoned off," said Daniel Andrews, the Premier of Victoria.

Before the new outbreak in Victoria, Australia recorded only a few new cases each week and was slowly relaxing, with the goal of opening the country at the end of July. But the past two weeks, Victoria recorded

The Victoria outbreak occurred in a familiar pattern: global public health officials warn that new outbreaks are inevitable even in countries that have virtually controlled nCoV,

In China, the outbreak was linked to a food market in Beijing last month, prompting officials to block many areas and conduct extensive tests, like what is happening in Australia.

In Australia, the nCoV attacked Melbourne, where government messages were not transmitted effectively to people, due to language barriers or other issues such as distrust of government.

Some of these areas also have high rates of homelessness and overcrowding, making it difficult to implement community isolation guidelines.

"If they don't work and don't get JobKeeper or JobSeeker benefits, they can only live on charity," said Eddie Micallef, president of the Victoria Community Council.

These threats have been warned since May, when a council of doctors and experts said the Australian government had missed the opportunity to protect immigrant communities.

Micallef and many other community leaders say state and federal government information on what to do to prevent infection has not been transmitted enough to high-risk groups.

"You must have an undergraduate degree to understand it," Mohammad Al-Khafaji, executive director of the Federation of Ethnic Communities Councils of Australia, said of the government's Covid-19 documents.

He and many other experts warn that a mandatory police-enforced blockade, amid police controversy around the world, could only make communities more alert to the authorities and cause

"We have to help them understand the importance of staying home. It's not through excessive punishment or oversight. That won't bring the change we seek," said Rebecca Wickes, associate professor.

She added that while the first wave of racism involving nCoV was aimed at Asians, the second wave targeting migrants and minorities had emerged.

Leaders of the Muslim community said they were anxious to become a "target" of discrimination when one of the Melbourne outbreaks originated from their traditional Eid festival last month.

For Mayar, removing prejudices about Covid-19 and the discrimination associated with knocking on door to door.

He admits that this can be risky.
