The re-emergence of neo-crowned pneumonia in the state limits the ability of public health institutions to detect, track and isolate cases.
Health authorities in other states, especially new south wales, are watching closely. They realized that the silent battle to contain the second wave of Coronavirus outbreaks in Melbourne was a test of the ability of widespread detection and local blockade to contain virus transmission.
The new state has explicitly ruled out re-closing the state, even in the event of a second wave of outbreaks. This means that broad detection, rigorous tracking of contacts, and isolation strategies will be the first line of defense if, as government warned, outbreaks occur regularly before successful research and development vaccine.
Is this the second wave?
According to the Aussie newspaper, experts disagree on whether the recurrence of the Coronavirus outbreak in Melbourne could be called a "second wave ". As the number of new cases per day approaches the peak of the first wave in April, authorities is most concerned about "high levels of community transmission ".
"What is happening in Melbourne is not in line with the classic definition of a second wave of outbreaks ," said Mary Louis McLurg, professor of epidemiology at the University of New South Wales and World Health Organization consultant Marylouise McLaws. "
When the number of infections in the region is close to zero and people think the fight against the epidemic has been successful, and then the disease breaks out again, says mr mcclaus, this is the "second wave ".
The "wake-up" of the new crown pneumonia in melbourne is just a "small fluctuation ", Brain Oliver the head of the respiratory medicine pathogenesis team at the sydney university of science and technology (UTS) and the woolcock institute (Woolcock Institute).
Rate of infection
At the peak of the new coronary outbreak ,73 people per million people in the UK were infected. At the peak of Australia`s first wave of outbreaks ,13 people per million were infected.
"Even with this slight fluctuation in Melbourne in Australia, the current infection rate may be less than one per million people ," Professor Oliver said. "So, relatively speaking, this is a very small thing around the world.
"But I think the danger of describing it as a trivial matter is that people will then ignore it. "If not controlled, what happened in Melbourne could lead to a massive outbreak. If we can`t control the situation, it will escalate. "
Standard response model
Federal Acting Director General Paul Kelly (Paul Kelly) this week described the state`s response to a renewed outbreak, including extensive detection, contact tracing, and isolation of close contacts as a model to be followed in the event of a future outbreak.
Kelly said these methods have been successfully used to contain a massive outbreak in northwest Tasmania.
"All of these measures were implemented in north-west Tasmania and are now being promoted in Melbourne ." We learned from that time that efforts and efficiency were important. detection, tracing and isolation are our three main weapons against this virus in the absence of vaccine and universally effective treatments. This is the way many other countries respond to local outbreaks. "
In melbourne, where the outbreak is severe, the health bureau is sure they have found almost every case because they are conducting very high-level tests. Health workers are carrying out house-to-door tests with test kits, carrying out up to 18000 tests a day, and it is estimated that nearly half of the people in the affected areas have been tested.
Interstate aid has been used to raise the level of contact tracker. The number of new cases per day remained steady this week, and expectations that the number of cases will begin to decline next week are growing. But experts say detection, tracking and isolation strategies will work only if the number of cases remains within a certain range. Once the number of cases has risen too high, tracking all close contacts is no longer feasible.
"And that will be a challenge to our public health infrastructure ," said Gerry FitzGerald, a professor of public health at Queensland University of Technology. "If we can detect all cases, make sure that the persons they have come into contact with are found, that they are isolated and tested, and that if we do so, it is possible to control the epidemic ".
