Omicron has filled up hospitals worldwide with COVID-19 patients, despite the variant causing milder symptoms than previous strains. In the U.S., hospitals have been warned about a potential huge wave of patients infected by the new variant. In Australia, New South Wales' Omicron cluster exploded to 31 cases, but no one was admitted to the hospital. However, as the variant is highly transmissible, it is still a concern for hospitals that are already overwhelmed with patients from previous COVID-19 waves.

What You'll Learn
Omicron cases in Australia
On December 29, 2021, Australia saw a surge in coronavirus cases as the Omicron variant spread across the country. This prompted Prime Minister Scott Morrison to schedule an emergency national cabinet meeting. New South Wales, the country's most populous state, reported three new virus-related deaths and 625 hospitalizations, including 61 patients in intensive care. Victoria reported four new deaths and 397 hospitalizations, with 62 patients in intensive care.
Testing centers were overwhelmed and thousands of people waited in long lines for hours to get tested. The outbreak also contributed to a shortage of blood donations, with the Red Cross Lifeblood donor center calling for donors to step up. The rising case numbers led to mandatory self-isolation for thousands of workers in the hospitality, entertainment, and airline sectors, resulting in canceled shows, closed restaurants, and postponed flights.
Despite the Omicron variant being less severe than the Delta variant, experts criticized the federal government for downplaying the severity of the new variant as hospitals filled up across the country. Dr. Stephen Parnis, an emergency physician from Melbourne, expressed concern about the government's response, stating that the surging number of cases would still result in a significant number of hospitalizations.
As of December 22, 2021, there were 10 confirmed cases of Omicron in Australia – nine in New South Wales and one in the Northern Territory. The Northern Territory recorded its first COVID-19 death, an unvaccinated woman in her 70s from the Binjari Aboriginal community. The outbreak in the Northern Territory started when an infected woman illegally entered the territory in late October, spreading the virus to multiple communities.

Omicron is highly transmissible
Omicron is a highly transmissible COVID-19 variant that has caused a surge in hospitalisations worldwide. While the variant generally causes milder symptoms, the sheer volume of cases has placed immense pressure on healthcare systems.
Omicron's high transmissibility can be attributed to its ability to reinfect people and break through vaccinations at higher rates than previous variants like Delta. It is important to note that the original strain of Omicron was more transmissible than Delta, with over 30 of Omicron's mutations affecting the virus's spike protein, which attaches to human cells. This increase in transmissibility has resulted in a rapid rise in infections, overwhelming hospitals despite the milder nature of the variant.
The high transmissibility of Omicron has had significant consequences for hospitals. Even though Omicron cases are often milder, the sheer number of infections has led to a surge in hospitalisations. Hospitals have struggled to cope with the influx of patients, particularly as they were already dealing with the impact of previous waves driven by variants like Delta. The combination of high transmissibility and the lag in hospitalisations has resulted in a challenging situation for healthcare systems.
Furthermore, Omicron's high transmissibility has had global impacts. Within four weeks of its emergence, Omicron became the dominant variant worldwide, affecting countries that had previously successfully contained COVID-19 through public health and social measures. The rapid spread of Omicron has resulted in a significant increase in cases, hospitalisations, and deaths worldwide, overwhelming healthcare systems and highlighting the challenges posed by highly transmissible variants.
To summarise, Omicron's high transmissibility has resulted in a surge of infections, contributing to a wave of hospitalisations. Its ability to reinfect and break through vaccinations has challenged healthcare systems, even with milder symptoms. The rapid global spread of Omicron has served as a stark reminder of the ongoing need for vigilance and preparedness in the face of highly transmissible COVID-19 variants.

Omicron cases in the US
The Omicron variant of the coronavirus has been detected in the majority of US states, with only three states—Montana, Oklahoma, and South Dakota—yet to identify the variant as of December 2021. Omicron is believed to be highly transmissible, with cases doubling every three days, and it may reduce the effectiveness of COVID-19 vaccines.
In December 2021, the Omicron variant was detected in nearly one-third of US states, prompting concerns about another wave of COVID-19 cases. The highly contagious nature of Omicron threatened to further accelerate hospitalizations, with New York declaring a state of emergency to help hospitals prepare for a potential surge in patients. The Omicron variant was first identified in South Africa, and by December 2021, it had spread globally, including to the US.
In early January 2023, a new Omicron variant, XBB.1.5, was found to account for about 41% of verified COVID-19 cases in the US, according to the Centers for Disease Control and Prevention (CDC). This variant is a relative of the XBB strain and has been predominantly documented in the northeastern United States. Experts are concerned that vaccines may be less effective against the Omicron variant, but they hope that even if cases rise, there won't be a significant increase in hospitalizations or deaths due to high levels of immunity in the population through infection, vaccination, or both.
New York has been particularly affected by the Omicron variant, with the state reporting a significant surge in COVID-19 cases. The governor of New York has taken proactive measures, such as requiring booster shots for healthcare workers, to prevent them from falling ill amid breakthrough Omicron cases. Additionally, Pfizer's antiviral COVID pill has shown effectiveness in preventing hospitalizations, even for Omicron cases.

Omicron is less severe than Delta
Omicron cases have filled up hospitals with more COVID-19 patients than any other surge of the pandemic. However, the illness is milder than Delta, with many cases, even hospitalised ones, being quicker to treat. While COVID-19 can still be dangerous for vulnerable patients or those who are unvaccinated, Omicron is less likely to inflict the same level of damage as the Delta variant. Patients are being hospitalised, landing in the ICU, and dying at lower rates than with earlier variants.
The percentage of patients needing mechanical ventilation is about half of what it was during last year's winter surge, and researchers at Kaiser Permanente found that hospitalised patients were 74% less likely to be on a ventilator than those infected with Delta. Omicron doesn't infect the cells deep in the lungs as well as Delta, so a smaller proportion of patients are developing acute respiratory distress syndrome, and fewer need to go on ventilators.
However, despite the illness being milder, the huge volume of patients means hospitals are still struggling to treat them all. U.S. hospitals have a heads-up on Omicron, but that doesn't mean they feel ready to deal with what could be a huge wave of patients infected by the new variant. Omicron is highly transmissible and reinfects people and breaks through vaccinations at higher rates than Delta. While boosters can help, many in the U.S. haven't had one.
A study by Imperial College London found no evidence of Omicron cases being less severe than Delta, based on the proportion of people testing positive who had symptoms or went to hospital. However, another U.S. study suggests that Omicron results in less severe COVID-19 than seen during the Delta wave, with shorter hospital stays, less need for intensive care, and fewer deaths. The lower COVID-19 disease severity during the Omicron period is likely related to higher vaccination coverage and booster use.

Hospitals are overwhelmed
In the United States, hospitals have been grappling with a wave of Omicron patients, with emergency rooms packed and patients waiting for days to be admitted to a bed. The situation is similar in Europe, where hospitalisations are rising, and concerns about capacity are mounting. The highly transmissible nature of Omicron has resulted in a rapid increase in cases, outpacing the ability of hospitals to cope.
Doctors and researchers have noted that while Omicron may be less severe than previous variants, it can still cause the same life-threatening complications, especially in unvaccinated and high-risk individuals. The reduced severity of the illness has been offset by the sheer number of infections, as Omicron's high transmissibility has led to a massive spike in cases. This has resulted in hospitals being overwhelmed, with staff struggling to treat the vast number of patients.
The situation has been exacerbated by longstanding issues within healthcare systems, such as staffing shortages and a lack of coordination and collaboration. The competitive nature of the healthcare industry has hindered the ability of hospitals to respond effectively to the pandemic. Additionally, the high cost of healthcare and the low profit margins have left hospitals with limited resources and little extra capacity to handle unexpected crises, such as the Omicron surge.
The impact of Omicron on hospitals highlights the vulnerabilities within healthcare systems and the need for improved preparedness and coordination. While governments have provided resources, the scale of the Omicron wave has overwhelmed hospitals, leading to concerns about their ability to provide care for all patients. The situation underscores the ongoing challenges faced by healthcare workers and the need for systemic changes to address these issues.
