There are no stricter requirements, but Australia’s top doctor uses strong language.
Amid an increase in novel coronavirus cases in Australia this winter, the country’s top health officer, Paul Kelly, has advocated a reintroduction to anti-coronavirus measures such as face masks.
Despite the fact that state governments have yet to reimpose restrictions, health experts are urging the public to revert to procedures in place during the “summer wave” of the initial Omicron variants in December and January.
“While three or four doses of vaccine are still quite successful in providing protection against severe illness in BA.4 and BA.5, immunization alone is not effective in preventing infection or virus transmission from person to person,” Kelly explained.
With nearly 800 deaths in the last 16 days, Australia currently has one of the highest daily morbidity and fatality rates for the disease in the world.
Vaccination peaked in the winter of 2020 as the vaccine became widely available, coinciding with a spike in cases in January, but it has since dropped precipitously.
The new vaccine does not use Omicron, although it is still effective.
The number of people infected with COVID-19, according to Australian Health Minister Mark Butler, “may be more than treble the roughly 300,000 instances reported in the past week.”
The capacity of the novel BA.4 and BA.5 subvariants to defy immunity (regardless of vaccine history or previous infection), along with weak personal protection practices, is the main force behind the current rise in cases, according to Kelly.
He anticipates that peak to rise.
Although vaccines have been shown to avert serious illness and death, they are not a panacea. This is due in part to the fact that our vaccinations are based on previous strains of the virus, from which Omicron continues to evolve.
However, the Australian Technical Advisory Group on Immunisation (ATAGI) points to research indicating that four months after the second injection, the antibody’s efficacy against the Omicron subvariant reduces to “very moderate” levels. Booster dosages have been reported to raise protection against symptomatic disease to 50 to 75 percent within three months, dropping to 40 to 50 percent four to six months later.
However, as the efficiency of the new variations declines, health professionals have begun to tighten their terminology regarding personal safety measures.
“We know that wearing masks can significantly minimize transmission and protect you or others,” Kelly explained this week. “If you’re out from home and in a crowded room, I strongly advise you to wear a mask.” This is how we can genuinely impact the spread of the virus in the coming weeks, safeguarding vulnerable individuals in our communities while also protecting our already stressed healthcare system.”
As of July 19, there were over 5,200 persons in hospitals with COVID-19.
Mask laws have not been strengthened, but in some circumstances they remain in place.
Masks can be an effective barrier to transmission, especially when worn by both sick and uninfected individuals.
P2 or N95 respirators were thought to be the most effective at reducing transmission, followed by surgical masks and fabric masks if properly placed.
However, while the government has opted not to tighten the rules for masks in public areas, some regulations remain.
Most jurisdictions mandate people of a specific age (usually 12 or 13 and older) to wear masks on public transportation, taxis, and carpools, hospitals, health, geriatric, residential, mental health, and disability care facilities, airplanes, and penal facilities. COVID-19 patients or people in close contact outside the home are frequently subject to the mask rule.
In early July, the Australian Health Protection Primary Committee (AHPPC), comprised of all state and territory chief health officers, also released an update to the public by shortening the COVID-19 reinfection period from 12 weeks to 28 days.
In addition to keeping up-to-date immunization certificates, it recommends “wearing N95 masks in busy indoor areas (including on public transportation)” and staying at home if you have COVID-19 symptoms, regardless of severity.
Good respiratory and hand hygiene, keeping interior spaces well ventilated, and having employers examine business policies to allow work-from-home and COVID-related sick leave provisions are also recommended.
“I believe we should take care and continue to employ existing control measures to avoid significant outbreaks,” said Dr. Abrar Chughtai of the University of New South Wales Sydney’s School of Public Health and Community Medicine. “A huge outbreak would not only result in more deaths, but would also strain health-care systems.” If universal mask usage is not made required in the next months, it may be introduced in busy and high-risk areas such as public transportation, retail malls, and major gatherings. This will also eliminate the need for additional unneeded procedures, such as locking.
“We are still not out of the pandemic, and new varieties are appearing, so we cannot relax. Vaccines should be promoted even if they are less effective against these new varieties because they are safe and reduce hospitalizations and deaths. The majority of deaths continue to occur among those who have not been immunized and have not received booster doses.”
Vaccines with provisional approval are available for children aged 6 months to 5 years.
Moderna’s COVID-19 vaccine has been provisionally licensed for use in children aged six months to five years by Australia’s Therapeutic Goods Administration (TGA). This does not mean that parents can suddenly obtain the vaccine for their children; ATAGI approval is still required.
Butler advocated seasonal influenza vaccination for this group, despite the TGA’s preliminary approval of the vaccine.
“If I have a message for parents of children under the age of five… Consider getting your child immunized against the flu,” he urged.
“At this point in the flu season, our flu vaccination rates for children under the age of five are falling short of historical levels. They are quite backward.” ” Children under the age of five, particularly those under the age of two, are particularly vulnerable to influenza.”
In the 24 hours leading up to the most current reporting date, Australia reported 50,248 cases, the country’s highest daily case total in two months.
