Over the past few months, there has been a growing body of evidence surrounding us. Sensational headlines have been warning about a potential “quad-demic” with a mysterious virus originating in China, while families have been battling flu for weeks and hospitals are struggling to cope. Just a year and a half after the end of the Covid-19 pandemic, the world is once again facing a surge in respiratory illnesses. This time, however, the spike in infections is not due to a new pandemic virus, but rather a seasonal increase in respiratory diseases. Each year, as the weather turns colder and drier and people spend more time indoors, various illnesses like colds and flu become more prevalent. This annual rise in respiratory conditions puts immense strain on hospitals globally, with hundreds of thousands of influenza-related deaths projected each year. This winter is no different, but is the current respiratory virus season really as severe as it appears? What has changed this time around, if anything? With multiple viruses circulating and a recent outbreak causing a global panic, could the true threat be slipping under the radar? In China, there is a surge in cases of an influenza-like virus called HMPV, particularly affecting children. How serious is the flu season of 2024/2025? Ask those who fell ill with the flu during the recent Christmas holiday in the UK, and they will likely describe a particularly harsh illness. The dominant strain this year, H1N1, has historical ties to pandemics from previous decades and is putting a significant strain on the country’s healthcare system. According to a report by the UK Health Security Agency, flu activity has risen sharply, leading to thousands of hospitalizations over the holiday period. While hospitalizations have increased dramatically, experts note that this is not unprecedented, comparing it to the 2022-23 flu season that resulted in around 5,000 deaths per week in England at its peak. Lower than usual vaccination rates may be contributing to the perceived severity of the UK’s flu season, particularly when compared to the previous year when a broader vaccination program was in place. Despite 73% of older adults receiving the vaccine, less than 35% of higher-risk adults of any age have been vaccinated so far this season, indicating a potential factor in the increased hospitalizations.
The current rate of uptake is insufficient at 90 per cent to effectively curb flu outbreaks. Among frontline health workers, only 42.8 percent received the flu jab during the 2023/2024 season. Despite the low vaccination rates, experts interviewed by The Telegraph indicated that this year’s influenza outbreak in the UK has been within expected levels, mirroring trends in other developed nations.
Contrary to earlier predictions of a “quad-demic” involving flu, Covid, RSV, and Norovirus, the scenario did not materialize as feared. Professor Paul Hunter from the University of East Anglia stated that while flu and norovirus cases are on the rise, RSV cases peaked in November, and Covid cases remain close to baseline levels.
The perceived threat from the surge in respiratory diseases can be attributed to the strain on essential resources such as hospital beds, staff availability, and treatment access. Professor Sir Andrew Pollard from the University of Oxford’s Pandemic Sciences Institute highlighted the challenge of managing healthcare systems near capacity during the winter surge in respiratory viruses.
The aging populations in high-income countries are exacerbating healthcare capacity challenges. Professor Pollard emphasized that demographic changes are leading to a continuous worsening of healthcare capacity issues over the coming decades without significant changes in health and social care management.
Additionally, the increased awareness of respiratory diseases post-pandemic has heightened alarm during routine illness cycles. This shift in perception is evident in the media coverage of surging hMPV cases in China causing panic in India, reflecting a broader global concern for potential pandemics.
Coined during the SARS crisis in the early 2000s, the term “infodemic” describes the rapid spread of false and misleading information during a disease outbreak, which can complicate public health responses. In India, health authorities have been attempting to reassure the public while also managing the seasonal increase in respiratory illnesses. Health Minister Jagat Prakash Nadda stated, “There is no need to worry. We are closely monitoring the situation, and the country’s health systems and surveillance networks are vigilant and prepared to respond promptly to any emerging health challenges.”
Due to India’s experiences with the COVID-19 pandemic and the public’s distrust of the government, there is skepticism about reports of mysterious diseases originating in China. The World Health Organization estimates a high death toll due to COVID-19, but the Indian government disputes these numbers. Additionally, there is political sensitivity surrounding health issues, as some Indian media outlets tend to sensationalize health crises, especially those connected to China.
The concern over hMPV, the disease that sparked recent worries, is somewhat misplaced as it is a common virus similar to the flu and is already prevalent worldwide. Despite this, the global coverage of the outbreak in China has led to an overwhelming amount of information and speculation. While the response to respiratory viruses this winter season seems disproportionate to the actual threat, the WHO has noted that China’s health care system is managing within expected levels for the winter season.
It is crucial to discern between sensationalist headlines and real health emergencies, as seasonal respiratory outbreaks are routine occurrences that should be handled with caution but not unnecessary panic.
It is almost certain that the next pandemic will be caused by a respiratory pathogen. Expert consensus points to respiratory diseases as the greatest threat, attributed in part to our physiological and social susceptibility – living in densely populated urban areas and communicating directly through the same orifices that respiratory viruses use for entry. Additionally, animals, especially those intensively farmed, also face vulnerability, serving as both a mutation reservoir and a conduit to humans.
A pressing concern currently is the emergence of a potential pandemic with H5N1 bird flu. While global attention is focused on hMPV, the H5N1 virus has made its way to cows, spreading through dairy and poultry farms, as well as zoos. This transmission has resulted in infections among millions of animals and dozens of individuals, predominantly agricultural workers. Recently, a man from Louisiana became the first recorded H5N1 bird flu fatality in the United States, believed to have contracted the virus directly from birds.
Although H5N1 does not yet possess human-to-human transmission capabilities, there is apprehension that a single mutation could confer this ability. Monitoring the US outbreak reveals concerns that H5N1 might mix with other circulating strains during the winter, potentially triggering a pandemic. While the media frenzy surrounding the current respiratory virus season may seem exaggerated, the impact of recurring outbreaks from known pathogens underscores the vulnerability of healthcare systems to emerging threats.
Professor Pollard notes, “These viruses pose a recurring challenge for the NHS annually.” Instead of solely addressing the immediate influx of patients, health authorities should focus on enhancing hospital and social care resilience to accommodate the elderly population’s burden. Implementing better-managed vaccination programs could mitigate hospitalizations during anticipated disease surges. Pollard emphasizes the importance of preparedness, citing the lack of resilience to confront a pandemic more severe than Covid-19, which had a mortality rate of less than one percent. The absence of readiness extends to handling routine winter seasons adequately.
In light of these considerations, it is essential for individuals to educate themselves on Global Health Security and stay informed about potential health threats.
