Australians have been warned to be wary of infectious Delta strains, and an expert said that we are “walking into a cloud of infectious particles.”
An epidemiologist described the positive cases as “walking into a cloud of infectious particles” and Australians have been warned to be wary of the highly contagious Delta strain.
Expectations from health experts suggest that New South Wales will see more cases Exposure location announced overnight, Including in Bondi and two “flights of concern”.
New South Wales Governor Gladys Berejiklian (Gladys Berejiklian) said that the authorities are now worried about the ease of transmission of this variant of the virus Yesterday announced the extension of mask measures for one week.
Mary-Louise McLaws, professor of epidemiology at the University of New South Wales and consultant to the World Health Organization, described the surge in numbers as “huge” and said that the Delta strain is undergoing unprecedented mutations
Although Professor McLoughs praised the decision to face masks, she revealed some terrible realities of the new variants. The world is paying attention to the “transitory” way the virus spreads.

In a conversation with ABC’s Gemma Veness, Professor McLaws said that this mutation means that people become more contagious earlier than its viral predecessor. This supports the study of Chinese doctors. They say that as many as 12% of patients are Three to four days after the onset of symptoms.
In the past, this proportion was only 2% or 3% of those infected.
“This worrying mutation means that you can start to become more contagious to people earlier, so we know that you are highly contagious to any mutation or wild strain when you develop symptoms around the 5th day. , But of course from the 3rd day onwards, of course it will still infect people,” Professor McLoughs said.
“With this particular delta, it looks like you are much more contagious,” she warned.
She suggested that the Bondi cluster in Sydney and the concerns about the exposure of its Westfield Bondi Junction complex may be because shoppers are walking into an “contagious particle cloud.”
As New South Wales health authorities increase their focus on venues, thousands of people who visit Bondi Westfield within a week will need to be tested.
Ms. Berejiklian said that the shopping mall has had “multiple cases” and the authorities want to ensure that they “catch everyone.”
Anyone who has visited the center (including the parking lot) between June 12 and 18 is required to come forward.
Professor McLoughs explained: “Usually you need at least a few minutes to breathe in, because we have seen that in most cases you get the new coronavirus from large droplets.”
“However, the more regrettably this pandemic continues, the more we learn that at different stages of the disease, you are more likely to exhale smaller particles than larger particles.
“So maybe what we are seeing is people walking in indoor shopping malls-where the air flow will not change much due to highly infectious diseases-the small particles they exhale will not fall to the ground very quickly, so you ‘Walking into a cloud of infectious particles.”
Professor Maclaus speculated that this is not “the fleeting passing through a path”, but “the fleeting passing through a strand of infectious aerosol particles.”
Eric Liang Feigl-Ding is a public health scientist in the United States. He took the Delta variant in Sydney as an example and told his more than 500,000 followers that “this kind of’short-term contact’ infection requires more masks, improved ventilation and air disinfection.”
“I think it is safe to say that Delta Variant is now the biggest threat to the COVID19 pandemic in 2021. It is the fastest known variant to date. The data collected by WHO from 64 countries will not lie. B16172 to the world It is an obvious and real danger.”
Currently has 21 infections in the Covid-19 outbreak in New South Wales.
Ms. Berejiklian said, “At this stage, we believe that the response we are taking is proportional to the risk” – but New South Wales Health Minister Brad Hazzard warned residents “very, very seriously Treat it”, especially because it is a more contagious variant of Delta.
She said: “I am very happy to hear that masks are now mandatory, not just mandatory in transportation, because it will save us from walking into these infectious particles.”
She claimed that children are more susceptible to this kind of pressure, “more than we have seen before.”
“Delta Air Lines has shown us that children can be infected with this virus. I have always been very sure that children will not be infected with the new crown virus unless they are family contacts.
“But it’s different. This delta has now worked out how to infect children.”
In March, the Prime Minister pointed out directly to Australians, Especially in their 20s and 30s, They seem to “think that because they are healthier, they are not spreaders of the virus.”
“They are spreaders of the virus,” Mr. Morrison said.
“Although they may only have mild cases themselves, this is not a guarantee, but what they do with this view is to put other people’s lives at risk.”
Professor McLoughs warned that those who have been partially vaccinated are urged to have a second vaccination, because if you are partially immunized and infected with the Delta strain, “you are now providing a playground for how the virus learns and mutates.”
Victoria joined South Australia overnight, imposing new restrictions on travellers from certain areas of Sydney, but Chief Health Officer Brett Sutton delivered a tougher message: “You can’t enter victoria“.
