The Omicron variant of COVID-19 has had a significant impact on healthcare systems worldwide, with hospitals facing challenges due to increased hospitalizations and staff shortages. Studies suggest that Omicron is less likely to result in severe illness and hospitalization, particularly in younger individuals, when compared to previous variants like Delta. However, the high transmission rate of Omicron has led to a significant surge in cases, which has, in turn, increased the overall number of hospitalizations. Additionally, Omicron has been associated with a higher risk of reinfection, and healthcare workers have reported observing severe disease in reinfected patients, especially the elderly with underlying health conditions. While the absolute number of hospitalizations may be influenced by various factors, the impact of Omicron on hospitals has been notable, and it has prompted changes in health policies and resource management strategies.

What You'll Learn
Omicron less likely to cause hospitalisation than Delta
The Omicron variant of the coronavirus has been associated with reduced vaccine effectiveness and milder symptoms. While the Omicron variant has led to an increased number of hospitalizations, studies suggest that Omicron is less likely to cause hospitalization than the Delta variant.
Two British studies provide early hints that the Omicron variant may be milder than the Delta version. The studies found that people infected with the Omicron variant are 20% less likely to be hospitalized and 40% less likely to be hospitalized for a night or more. The studies also found that the risk of hospitalization was two-thirds less with Omicron than with Delta. However, it is important to note that the Omicron cases in these studies were predominantly among younger adults aged 20-39.
A separate study out of Scotland by scientists at the University of Edinburgh and other experts found that the risk of hospitalization with Omicron was 65% less than with Delta. This study included 24,000 Omicron cases, the majority of which were among younger adults aged 20-39.
Data out of South Africa, where the Omicron variant was first detected, also suggest that Omicron leads to milder disease. Salim Abdool Karim, a clinical infectious disease epidemiologist in South Africa, stated that the overall admission rate for Omicron was around 2-4%, compared to 20% for Delta.
While the findings on Omicron are encouraging, it is important to emphasize that Omicron has a much higher transmission rate than Delta. Therefore, the absolute number of people requiring hospitalization could still increase, despite the milder disease. In addition, the reduced severity of COVID-19 hospitalizations could be due to increased population immunity, greater availability of treatments, and updated clinical management strategies.

Hospital capacities challenged by Omicron
The Omicron variant of the coronavirus has had a significant impact on hospital capacities worldwide. While studies suggest that Omicron may be less likely to result in hospitalization compared to previous variants like Delta, the high transmission rate of Omicron means that the absolute number of people requiring hospitalization can still be significant. This has placed considerable strain on healthcare systems, particularly in terms of staffing and resource availability.
In the early stages of the Omicron wave, hospitals reported a sharp increase in cases, with many parts of the world seeing a rise in hospitalizations. This surge presented unique challenges for hospitals, as Omicron's high transmissibility led to a rapid increase in cases, impacting healthcare workers and causing cancellations of non-urgent procedures. Despite Omicron causing less severe illness in most cases, the sheer volume of infections has created stress on hospitals and intensive care units (ICUs).
In addition, Omicron's ability to evade vaccines and infect vaccinated individuals has contributed to the strain on hospitals. While vaccinated individuals are generally less likely to experience severe illness requiring hospitalization, the high infectivity of Omicron has resulted in a substantial number of breakthrough infections, leading to increased hospitalizations among the vaccinated population. This trend has been particularly notable in areas with lower vaccination rates, where unvaccinated individuals are at a higher risk of severe disease and hospitalization.
Furthermore, Omicron's propensity for reinfection has also played a role in challenging hospital capacities. Reports from China indicate a significant increase in reinfections, with the virus causing severe disease, especially in elderly individuals with underlying health conditions. The high rate of reinfections has further strained healthcare resources and impacted bed availability.
While the overall severity of Omicron infections may have decreased compared to previous variants, the sheer number of cases and the unique characteristics of the variant have nonetheless posed significant challenges to hospital capacities worldwide. The impact of Omicron on hospitals highlights the ongoing need for public health measures, including vaccination, to mitigate the strain on healthcare systems and ensure their ability to provide care for those who need it most.

Staff shortages due to Omicron
Omicron has had a significant impact on staffing levels across various sectors, from healthcare to logistics and aviation. Hospitals have been particularly affected, with staff shortages creating a crisis situation in some cases. At Rush University Medical Center in Chicago, makeshift emergency rooms were set up in different parts of the hospital, including the lobby, to cope with the surge in patient numbers. Dr. Omar Lateef, a pulmonary critical care physician and the hospital's president and CEO, expressed his fear of running out of staff, with 3-5% of the workforce absent on any given day. The situation is exacerbated by the existing nursing shortage and the highly transmissible nature of the Omicron variant, leading to increased infections among healthcare workers.
The healthcare system in the United States has been strained by Omicron-related hospitalizations, with approximately one-third of adult intensive care unit beds occupied by COVID-19 patients at the peak of the variant's surge. This has resulted in critical staffing shortages in 24% of hospitals across the country. The volume of hospitalizations and staff absences has posed a significant challenge to local healthcare systems, with trust leaders expressing concern about the impact on remaining staff workloads.
The logistics industry has also faced disruptions due to Omicron. Warehouse operators are under pressure from seasonal demand and an increase in returns, compounded by staff shortages as more workers are isolating. Businesses are urged to invest in manual handling equipment to maintain operational efficiency despite the lack of staff.
Other notable employers affected by Omicron-related staff shortages include Macy's, which has reduced store hours, and United Airlines, where nearly a third of the workforce at Newark Liberty International Airport called out sick on a single day. The Smithsonian's National Zoo in Washington, D.C., has also adjusted its opening days, now operating from Thursday to Sunday.
While Omicron may be associated with less severe disease and lower hospitalization rates compared to previous variants, the highly transmissible nature of the variant has still resulted in a significant number of hospitalizations, contributing to staff shortages across various sectors.

Reinfection and severe disease in China
Several studies have shown that the Omicron variant is less likely to result in hospitalisation when compared to the Delta variant. However, due to its higher transmission rate, the absolute number of people requiring hospitalisation might still increase. In the United States, the Omicron variant led to a significant challenge for local healthcare systems, with an increase in hospitalisations and associated staff shortages.
The Omicron variant has a higher reinfection rate than previous variants, and this has been a challenge for the global response to the pandemic. A cross-sectional study conducted in Shanghai, China, estimated the Omicron reinfection prevalence among people who had previously been infected with the virus. The study found that among the 1981 respondents who were infected between March and May 2022, 260 tested positive again in December 2022, resulting in an estimated reinfection rate of 13.1%. The reinfection rate was lower for those who had received a booster vaccination (11.4%), and the highest risk of reinfection was observed among those who were unvaccinated or incompletely vaccinated. Hybrid immunity, particularly against the Omicron variant, has been recognised as the most resilient approach to combating SARS-CoV-2.

Vaccination and boosters to prevent hospitalisation
Vaccination is a critical tool in the fight against COVID-19 and its variants, including Omicron. While the Omicron variant has been associated with milder symptoms and lower hospitalisation rates compared to previous variants, vaccination and booster shots remain crucial in preventing severe illness and reducing hospitalisations.
Firstly, vaccination can reduce the risk of infection and slow the spread of the virus. This is especially important given Omicron's high transmissibility. By preventing infections, vaccines alleviate the burden on healthcare systems and reduce the overall number of hospitalisations.
Secondly, for those who do contract COVID-19, vaccination and boosters play a vital role in preventing severe illness and hospitalisation. Studies have shown that vaccinated individuals who contract COVID-19 are less likely to require hospitalisation and intensive care unit (ICU) admission. Vaccines also reduce the risk of death. This protection against severe disease is especially important for high-risk groups, including the elderly, immunocompromised individuals, and those with underlying medical conditions.
To maintain protection against COVID-19 and its variants, it is essential to stay up to date with vaccinations. Vaccine protection wanes over time, and new variants like Omicron can evade immunity from previous infections or vaccinations. As such, booster shots are recommended to restore and enhance protection. The 2024-2025 COVID-19 vaccines, for instance, are updated to provide better protection against currently circulating strains, including the Omicron variant.
In addition to vaccination, public health measures such as mask-wearing, social distancing, and hand hygiene are crucial in preventing hospitalisations. These measures, when combined with vaccination and boosters, form a comprehensive strategy to reduce the impact of COVID-19 and keep hospitalisations low.
