covid predictions for 2022 australia

The vaccines now in wide distribution still limit the incidence of severe disease. In reality, people mix mostly with others whose patterns of interaction are similar to their own. Although each individuals level of immunity cannot be measured in real time, we can base estimates of the level of community risk on what is known about vaccination rates and previous infections. For an example of a low-end estimate, see Max Fisher, R0, the messy metric that may soon shape our lives, explained, New York Times, April 23, 2020, nytimes.com. Of these deaths, 4,547 occurred in 2022 more than double the 2,239 deaths recorded over the first two years of the pandemic. Its also possible that once most people in the highest-risk groups have received vaccinations, the pace of vaccination will slow if lower-risk groups do not embrace the opportunity. Some countries in this group, such as Australia, have recently faced a Delta-driven surge in cases, but in absolute terms the burden of disease remains low relative to other countries. Some recent studies suggest that a significant number of people who havent contracted COVID-19 have cross-reactivity in specific immune cells (T cells). One such indicator may be consumer behavior. Women will return to work within a year of childbirth in high numbers. to advise boosters for most Americans 8 months after vaccination, New York Times, August 16, 2021, nytimes.com. Herd immunity to a pathogen is achieved when a sufficient portion of a population is simultaneously immune to prevent sustained transmission. This has prompted some high-income countries to start offering booster doses to high-risk populations or planning for their rollout.85 Kate Brady and Reis Thebault, Europe to give covid booster shots as half the world is still starving for vaccines, Washington Post, August 4, 2021, washingtonpost.com; Sharon LaFraniere, U.S. More recent data, as previously described, highlight the benefits of booster doses in protecting against the Omicron variant. 11. 6. They have typically maintained tight border restrictions and a strong public-health response to imported cases. Since the Omicron variant of COVID-19 was named by WHO on November 26, 2021, it has moved at lightning speed. They vary widely, from as low as 1 to 2 percent in some states like Colorado and Kansas to 14 to 20 percent in New Jersey and New York.161Nationwide commercial laboratory seroprevalence survey, Centers for Disease Control and Prevention, accessed November 15, 2020, covid.cdc.gov. Second, public willingness to be vaccinated is generally similar between the two countries.148Jeffrey V. Lazarus et al., A global survey of potential acceptance of a COVID-19 vaccine, Nature Medicine, 2020, nature.com. What role will antibody treatments play? A transition to the next normal, in whatever form that takes, will come gradually when people have confidence that they can do what they used to do without endangering themselves or others. We see similar dynamics in the United Kingdom. Treasury is estimating a historical surge in net migration, but several factors including changes to COVID policy settings make the prediction seem far-fetched. Even as some locations reach herd immunity, pockets of endemic COVID-19 disease are likely to remain around the world, for example in areas affected by war or in communities with persistently low adoption of vaccines. Nevertheless, recent results from MerckRidgeback Biotherapeutics and Pfizer on their oral drugs molnupiravir and PAXLOVID, respectively (two antivirals, with different mechanisms of action65Merck and Ridgeback Biotherapeutics provide update on results from MOVe-OUT study of molnupiravir, an investigational oral antiviral medicine, in at risk adults with mild-to-moderate COVID-19, Merck, November 26, 2021; Pfizers novel COVID-19 oral antiviral treatment candidate reduced risk of hospitalization or death by 89% in interim analysis of Phase 2/3 EPIC-HR study, Pfizer, November 5, 2021.) "Australia, as a neighbour there, really has a responsibility to help with the infrastructure and with the messaging and to try [to]get those populations vaccinated," he said. Delta variant: What we know about the science, US Centers for Disease Control and Prevention, August 26, 2021. SARS-CoV-2 variants of concern and variants under investigation in England: Technical briefing 31, UK Health Security Agency, December 13, 2021. Pfizer and BioNTech provide update, December 8, 2021; Khristopher J. Brooks, CEOs and scientists on whether existing vaccines will work against Omicron, CBS News, December 8, 2021. predictions for 2022 That trend is likely to continue whilst the special COVID rulesfor working holidaymakers introduced by the Coalition Government remain in place and the labour market remains strong. ; and progress on therapeutics. Europe and the United States have entered the endemic stage of the COVID-19 outbreak: the virus is widespread, is significantly less fatal than it was in 2020, and is spurring only limited changes in public behavior. Coronavirus (COVID-19) case numbers and statistics Expect more vacancies on your local main street. As Australia battles its latest COVID-19 wave, many will be hoping 2023 is the year the pandemic "ends", the year that weighing-up exposure risks, mask use, skipping social events due to that tickle in the throat, can all be put behind us. For example, the Delta variant, which remains dominant in most of the world, was significantly more transmissible than previously circulating variants were, showed limited incremental evasion of immunity, and caused moderately more severe disease relative to other variants.56Delta variant: What we know about the science, US Centers for Disease Control and Prevention, August 26, 2021. Becky Morton and Doug Faulkner, Covid: First UK death recorded with Omicron variant, BBC News, December 13, 2021; Mahsa Saeidi, South Africa reports rise of omicron hospitalization of kids under 5, initial data shows, WFLA, December 6, 2021. So which ones are best? COVID-19 Vaccines and Vaccination. Our analysis offers some scenarios to understand potential outcomes. But with strong community response to prevention measures, hard work from the health sector and a stroke of good luck, we dodged the worst-case scenarios. Every exposure, every sniffle. What's new this quarter For example, with a variant that is 40 to 80 percent more transmissible, vaccine efficacy of 90 percent would require 83 to 100 percent of those over 12 to be vaccinated; efficacy of anything less than 75 percent would make herd immunity likely unachievable through vaccination of only those over 12. Its likely that many more infections havent been detected. As populations get closer to this state, it may be helpful to introduce some nuance to what we mean by the term. Since then, several other vaccines have been authorized for use around the world. A fair bit of this disposable income will be used to make the family home more liveable. It's unclear at what price these changes come, in terms of increased risk to essential workers and their families. We should be focusing more on interventions that are sustainable that is, ones that we can maintain as we get back to living our lives normally. COVID Its not only hospitalisation and deaths its long Covid [too].. They estimate that the proportion of infected people was at least twice as high as indicated by cases reported to authorities by the end of February 2022. Of course, we're not alone the whole world is being buffeted. Many governments are employing packages of measuresthat aim to minimize the number of COVID-19 cases and excess mortality while maximizing social and economic degrees of freedom. Immunity protects individuals and reduces risk for people in the community around them by reducing rates of onward transmission. SARS-CoV-2 will continue to exist. The Stats Guy: 22 predictions of what 2022 holds for Australia 1. We also look at the effects of boosters, the potential waning of vaccine efficacy, and new oral therapeutics. While the winter of 2020/2021 in the Northern Hemisphere will be challenging, we are likely to see mortality rates fall in Q2 (or possibly late Q1) of 2021. But at the time of writing, the Omicron variant is rewriting the timetable. Lets face it Microsofts introduction of the ChatGPT (generative AI) enabled Bing search engine as well as the ChatGPT embedded co-pilot in all Microsoft Office Fifth, and most concerning, variants that reduce the efficacy of vaccines or the benefits of natural immunity may spread widely. Laura DeFranceso, COVID-19 antibodies on trial,, Leora Horwitz et al., Trends in COVID-19 risk-adjusted mortality rates,, Kevin Hartnett, The tricky math of herd immunity for COVID-19,, Marc Lipsitch et al., Understanding COVID-19 vaccine efficacy,. They are keen to travel, spend time with the grandkids, and feel its their time now. Prior natural infection with a different variant appears to provide only partial protection against Delta. At this stage, when monthly mortality from COVID-19 may start to resemble that of flu in an average year, we may see a transition toward normalcy, albeit with public-health measures still in place. "It's hard because it doesn't have an enormously robust diagnosis," Dr Lydeamore said. We wanted to reduce the risk, even if people get infected, of going on to develop severe disease and die. Up until recently, the original Omicron strain, BA.2, had been the dominant strain. Follow Us. Delta variant: What we know about the science, Centers for Disease Control and Prevention, updated August 19, 2021, cdc.gov; Yasmeen Abutaleb, Joel Achenbach, and Carolyn Y. Johnson, The war has changed: Internal CDC document urges new messaging, warns delta infections likely more severe,. First, access to vaccines is sufficient to immunize a large percentage of both the US and UK populations during 2021. It is gained through vaccination (primary series and boosters), infection with SARS-CoV-2, or both (hybrid immunity). Get The New Daily free every morning and evening. Some new studies suggest that infection confers more immunity and protection against severe disease than does vaccination alone. COVID-19 Projections - Institute for Health Metrics and Evaluation These endemic conditions are likely to continue through the summer and autumn, unless and until immunity-evading new variants emerge. During the anticipated period, the Australia infection control market in is anticipated to expand significantly. To get a doctor's certificate for work, the single mother had to fork out $100 for a telehealth appointment which was not covered by Medicare. Professor Esterman said there were a number of reasons why such big numbers could be flying under the radar. Another consequence is that older children, who have twice the COVID-19 incidence of younger children and who have higher viral loads (and therefore greater potential contagiousness) than adults158Rebecca Leeb et al., COVID-19 trends among school-aged childrenUnited States, March 1September 19, 2020, Centers for Disease Control and Prevention, October 2, 2020, cdc.gov; Lael Yonker et al., Pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2): Clinical presentation, infectivity, and immune response, Journal of Pediatrics, August 19, 2020 jpeds.com. Australia Merck expects COVID-19 pill molnupiravir to be effective against Omicron, Reuters, January 11, 2022, reuters.com. Society has grown used to tracking the number of COVID-19 infections (the case count). One is that each member of a population mixes randomly with all other population members. "Want to get a fast test? The formula relies on several broad assumptions. If T-cell cross-reactivity provides meaningful immunity, it would offer significant progress toward herd immunity. Variant prevalence is taken from Outbreak.info, which summarizes the data uploaded to GISAID. Despite his grim outlook on COVID-19 deaths, Professor Esterman said its not all doom and gloom. Protection against any infection (including asymptomatic disease) is likely to be lowerand protection against severe disease is likely to be higher. It is now harder to imagine the United States or United Kingdom transitioning to normalcy before second quarter 2021 or reaching herd immunity before third quarter 2021. South Australia and Tasmania, too, have an established surge. There are two issues. Flare-ups and localized epidemics would happen while COVID-19 is managed as an endemic disease, but scenario modeling suggests that these may have less of an effect on the whole of society than the waves seen to date. Watch the U.K. to understand Delta, August 2021; Grady McGregor, Sophie Mellor, and Biman Mukherji, Delta waves in India and the U.K. have already receded. Age demographics will continue to be an important risk driver. CDC strengthens recommendations and expands eligibility for COVID-19 booster shots, US Centers for Disease Control and Prevention, May 19, 2022; Updated joint statement from ECDC and EMA on additional booster doses of COVID-19 vaccines, European Centre for Disease Prevention and Control, July 11, 2022. Official sees strong possibility Covid shots will be given every autumn,. This will hurt low-income earners in regional Australia. Omicron is already among the most infectious human viruses known to science.40See Exhibit 1. "He said:'Look, half of Australia's got COVID at the moment there's nothing to report really,'" she said. If early vaccine doses reach a significant percentage of high-risk elderly individuals by the end of quarter one, the combination of protecting these groups and the arrival of spring in the northern hemisphere should improve the situation compared with where the United States is now. While 96 per cent of Australians aged 16 years or older have had the recommended two vaccine doses, only just over 70 per cent have had a third dose to boost their protection against severe illness. COVID-19 deaths on the rise: Epidemiologists grim prediction for Australia, Not so fast: Tony Abbott calls for the Voice referendum to be cancelled, The night I cooked schnitty for Barry Humphries, actual number of virus cases at the peak of the Omicron wave was likely double, Omicron wave cases double reported: Study. Dr Lydeamore said the fact that multiple branches of evolution of the virus were ending up in a similar position was a sign of "convergent evolution", and could be a good thing. BioNTech: watchdogs' requirements may defer planned launch of Omicron shot, Reuters, January 25, 2022, reuters.com. In countries where vaccination rates remain low, the prospects for ending the pandemic remain largely tied to the availability and administration of additional doses. "The danger will be that, if a variant emerges somewhere that can be anywhere in the world that is more severe, starts to put more people in hospital or increase mortality, that's when the real risk comes in for the next 12 months.". At worst, we see a long-tail possibility that the United States could be still battling COVID-19 into 2023 and beyond if a constellation of factors (such as low efficacy of vaccines and a short duration of natural immunity) align against us. Immunity each day is considered with respect to the dominant variant in circulation in the population in each country. More than a week since testing positive, Ms Spooner has beencareful to avoid spreading the disease. Yes, its no longer an absolute acute emergency like it was, because we have a large percentage of our population vaccinated and weve got better treatments. While an initial course of all WHO-approved vaccines continues to provide strong protection against severe illness and death, the rate of breakthrough cases increases meaningfully as time passes, indicating that protection declines with time. In the meantime, the current approach appears to have had substantial and mostly negative effects on both the Chinese and the global economies.4Paul Mozur and Alexandra Stevenson, In China, concerns grow over the economic impact of zero Covid, New York Times, May 26, 2022; Ji Siqi, China coronavirus: Shanghai restrictions caused more severe economic hit than previous lockdowns, China Macro Economy, June 1, 2002. If they fail to do so, regional house prices will continue to rise sharply. The curve rises sharply from Q1 2021 to a peak between Q3 and Q4 2021. NSW Health Minister Brad Hazzard suggested on December 15 just 18 days ago, when the state recorded 1,360 cases a day that NSW should brace for 25,000 cases a day by the end of January. This data will be published in 2022 and will show that Australians had even fewer kids during COVID there will be no coronavirus baby boom. The emergence of Omicron during the winter of 202122 is visible as a sharp drop in immunity in multiple countries (since existing immunity was suddenly less effective against the new variant). More retail spending will take place online. Francesco Guarascio, Moderna eyes COVID booster by August, not clear yet if Omicron-specific needed, Reuters, February 17, 2022, reuters.com. Levels of natural immunity from prior infection vary within the European Union but are generally in the same range as in the United Kingdom and the United States.125SeroTracker, last accessed March 15, 2021, serotracker.com. In the United States, COVID-19 hospitalization and mortality rates in June and July were nearing the ten-year average rates for influenza but have since risen. Nature, June 17, 2022. Xer leaders introduce generous parental leave policies and continue to fight for equal pay. Allowing for the risk of another new variant and the compound societal risk of a high burden of influenza, respiratory syncytial virus, and other winter respiratory diseases, the question for these countries will be whether they manage to arrive at a different epidemiological endpoint, as we discuss next. Beyond the cancelled plans and missed Christmases, we don't really have a way to judge the real damage done by the poor testing situation. Omicron: School closures must be avoided whenever possible, United Nations, December 17, 2021, news.un.org. Europe splits on Omicron response,. An alarming spike in COVID-19 and flu cases in Australia could put the U.S. on track for what health experts call a twindemic a dangerous viral one-two punch in In its final study, Pfizer reported that PAXLOVID reduced risk of hospitalization or death by about 89 percent for high-risk patients and about 70 percent for standard-risk patients.66Pfizer announces additional Phase 2/3 study results confirming robust efficacy of novel COVID-19 oral antiviral treatment candidate in reducing risk of hospitalization or death, December 14, 2021. This potential delay represents a call to action for policy makers, both in terms of the pace of the vaccine rollout and how new strains are managed. Sarun Charumilind and Jessica Lamb are both partners in McKinseys Philadelphia office, Matt Craven is a partner in the Silicon Valley office, Adam Sabow is a senior partner in the Chicago office, and Matt Wilson is a senior partner in the New York office. We're running a completely different race but we're still trying to follow the old rules. Long-term drivers for expanded demand remain Populous emerging markets are still likely to want more air services Return to growth post-COVID but at a lower level Global RPKs forecast to be 32%-41% below expected levels in 2021 Global RPK medium term scenarios Pre-COVID forecast Current baseline COVID setback scenario risk that A media law expertexplains, Hopes high that Australian drug may stop brain cell death after traumatic births, Autopsies begin on more than 100 bodies of Kenyan cult members, Fifth man charged over Sydney gangland shooting of Mahmoud Ahmad, Fijis former attorney-general Aiyaz Sayed-Khaiyum taken into custody over alleged abuse of office, Support overwhelms referee as alleged attacker jailed, NRL concedes knock-on error on crucial golden point call for Raiders. But the same shortfalls in access that bedevil the distribution of vaccines in low-income countries are striking again with therapeutics: doses sit unused in high-income countries while other parts of the world lack access.12Ann Danaiya Usher, The global COVID-19 treatment divide, National Institutes of Healths National Library of Medicine, February 24, 2022. Covid For COVID-19, it can be generally thought of as the expected number of cases directly generated by a single case in a population in which all people are susceptible. The proportion of the population with effective immunity for both COVID-19 vaccines and prior infection is separated from the aforementioned proportions of the population with effective immunity from COVID-19 vaccines only and from the population with effective immunity from prior COVID-19 infection only. The official statistics, which already tend to underestimate the number of cases, may become even less sensitive to the true dimensions of viral transmission. While many people in the United States are growing comfortable living alongside COVID-19, the average number of daily deaths still runs at two to four times the long-term average for influenza, and its higher on a seasonally adjusted basis.5Coronavirus in the US: Latest map and case count, New York Times, July 5, 2022; Past seasons estimated influenza disease burden, US Centers for Disease Control and Prevention, accessed July 24, 2022. Some are close to eliminating excess mortality. We hope that this article offers a starting point to interpret the potential spread and severity of the disease it produces and the ways in which new therapeutics, booster doses of vaccines, and public-health measures will be important in limiting its impact. If these strains become dominant, they may cause a material delay in reaching herd immunity. A third is demographics: while the younger populations of many lower-income countries have led to lower COVID-19-associated mortality, they also make it harder for adult-only vaccination programs to drive herd immunity. "We perhaps overdid it early on, so the risk perception was too high. The end of Europes pandemic may come somewhat later, and other countries outlooks will depend on several variables. More-infectious strains of SARS-CoV-2 therefore raise the bar on herd immunity. Our analysis suggests that in the United States, this combination of characteristics would lead to Omicron replacing Delta as the dominant variant in the next few months and to a higher peak burden of disease than the country saw in the second half of 2021 (but likely below the peak reached in the winter of 202021). Cases moved from double digits on December 21 to well into the 3,000s by year's end. Science Brief: Indicators for Monitoring COVID-19 Community Levels and Making Public Health Recommendations. may not have immediate access to vaccines. Third, and consistent with this trend, some governments have concluded that the total societal costs of lockdowns, restrictions on business, or masking outweigh the benefits at this phase of the pandemic.27Nicholas Casey and Norimitsu Onishi, Crack down hard, or wait and see? For an example of a high-end estimate, see Seth Flaxman et al., Estimating the effects of non-pharmaceutical interventions on COVID-19 in Europe, Nature, August 13, 2020, Volume 584, pp. Anthony Ives and Claudio Bozzuto, State-by-state estimates of R0 at the start of COVID-19 outbreaks in the USA, MedRxiv, May 27, 2020, medrxiv.org. The relationship between waning antibodies and reinfection risk remains unclear. We acknowledge Aboriginal and Torres Strait Islander peoples as the First Australians and Traditional Custodians of the lands where we live, learn, and work. Depending on vaccination progress over the summer (whether the United States is on the earlier or later end of the herd immunity window), there may be a smaller fall wave of disease in third to fourth quarter 2021. We've heard the horror stories testing centre queues so long they were closed just minutes after opening time, friends who'd visited upwards of five sites trying to get a pre-holiday test, people with long-standing medical appointments missing out on a required PCR test.
