In a worrying new trend, the number of patients in English hospitals infected with norovirus has reached an all-time high, according to the latest data from NHS England. Norovirus, also known as the “winter vomiting bug,” is highly contagious and typically causes vomiting and diarrhea. While most people recover within a few days, the illness can be severe for vulnerable groups such as older adults, young children, and those with weakened immune systems. The rise in hospitalizations comes amid concerns that post-pandemic behaviors—particularly a decrease in hand hygiene practices—could be contributing to the surge in cases.

The Rise of Norovirus Hospitalizations

Recent figures indicate that, on average, 1,160 patients per day were admitted to hospitals with norovirus last week, marking a 22% increase from the previous week. Last year, this figure was only 509 patients per day. The sharp increase in cases has raised alarms among health professionals, as hospitals are already stretched thin with high levels of admissions for other winter viruses such as Covid-19, respiratory syncytial virus (RSV), and flu. Two weeks ago, the highest daily average of norovirus patients was recorded at 961.

This alarming trend comes at a time when the NHS is grappling with near capacity hospital beds. More than 95% of adult beds are occupied, with delays in patient discharges contributing to the strain. Nearly one in seven beds are occupied by patients who are medically cleared to leave but are still occupying valuable space due to administrative delays or a lack of available discharge facilities.

Impact on Hospital Capacity and Healthcare Workers

Prof Sir Stephen Powis, the national medical director of NHS England, voiced concern over the situation, stating that the all-time high in norovirus patients is placing enormous pressure on hospital staff. Healthcare workers are already dealing with more than a thousand daily cases of the virus, in addition to other winter viruses. This increased patient load is compounded by the fact that the healthcare system is experiencing substantial strain from rising Covid-19 hospitalizations and a growing number of children being admitted with RSV.

“It’s concerning to see the number of patients with norovirus hit an all-time high, and there is no let-up for hospital staff who are working tirelessly to treat more than a thousand patients each day with the horrible bug, on top of other winter viruses,” Powis said. He emphasized the importance of proper hygiene practices in preventing the spread of norovirus, particularly frequent handwashing with soap and water and avoiding contact with others until symptoms have been gone for at least two days.

The Role of Post-Pandemic Hygiene and Behaviour

One of the primary factors contributing to the rise in norovirus cases is a shift in hygiene habits after the Covid-19 pandemic. During the height of the pandemic, hand sanitizing and frequent handwashing became an essential part of public health protocols. However, research conducted by Dr. Simon Williams, a behavioral scientist at Swansea University, reveals that this vigilance has declined since the pandemic ended. As people have become less concerned about the spread of viruses, hygiene habits have reverted to pre-pandemic levels.

Williams points out that surveys show that a significant number of people have become less diligent about washing their hands after using the toilet or before preparing food. “Around one in five people don’t always wash their hands after using the loo, and about four in ten don’t wash before handling or cooking food,” Williams explained. This decline in hand hygiene is seen as a key contributor to the resurgence of norovirus cases, which is primarily transmitted through contaminated surfaces and food.

In addition to hygiene lapses, presenteeism—when individuals go to work or school despite being ill—has exacerbated the situation. Norovirus is typically spread by individuals who are symptomatic, and their decision to continue attending work or social settings can inadvertently spread the virus to others, particularly those in vulnerable groups. Williams suggests that people who are symptomatic should take more care to avoid close contact with others and refrain from sharing food or drinks to reduce transmission.

Norovirus and Its Impact on Vulnerable Populations

While norovirus is usually a short-lived illness for healthy individuals, it can have more serious consequences for vulnerable populations. Those who are elderly, immunocompromised, or very young may experience more severe dehydration and complications as a result of the virus. In some cases, these complications may require hospitalization or medical intervention.

For older adults and individuals with chronic health conditions, the dehydration caused by vomiting and diarrhea can be particularly dangerous. In these cases, medical attention may be required to manage symptoms and ensure that the patient does not suffer from further health deterioration. The increased number of cases has raised concerns about the strain placed on the healthcare system, particularly with the hospital’s capacity already stretched thin due to other viruses.

What Can Be Done to Prevent the Spread of Norovirus?

Despite the concerning rise in cases, experts argue that norovirus outbreaks are preventable with simple hygiene measures. Public health officials recommend frequent handwashing with soap and water, particularly after using the toilet and before preparing food. While alcohol-based hand sanitizers can be effective, they are not as reliable against norovirus as handwashing with soap and water. Those who are symptomatic are urged to stay home from work or school and avoid contact with others for at least 48 hours after symptoms have subsided to prevent the virus from spreading.

In addition to better hygiene practices, individuals are also encouraged to avoid sharing food or drink, particularly in enclosed spaces such as offices, schools, and public transportation, where the virus can spread rapidly. Educating the public about the importance of proper hygiene and staying home when sick could go a long way in curbing the spread of norovirus and protecting vulnerable populations from its potentially harmful effects.

A Long-Term Solution: Return to Preventive Measures and Vigilance

The rise in norovirus cases serves as a reminder of the importance of hygiene and preventive healthcare measures. The Covid-19 pandemic showed that increased awareness of hygiene practices can help curb the spread of contagious diseases. As the UK navigates the post-pandemic world, there is a need to reinstate these measures and encourage the public to adopt long-term hygiene habits to prevent the spread of illnesses such as norovirus.

Additionally, better public health campaigns and stronger policies to promote sick leave, especially for those with contagious illnesses, could help reduce presenteeism and the transmission of norovirus in workplaces and schools. Health professionals also call for more education and awareness about norovirus and its risks, particularly for vulnerable populations, so that people can take the necessary steps to protect themselves.

The Importance of Public Health Measures and Vigilance

The surge in norovirus hospitalizations is a concerning development, but it is not an insurmountable challenge. By adhering to basic hygiene practices, avoiding contact with others while symptomatic, and prioritizing the health and well-being of vulnerable groups, it is possible to reduce the spread of the virus and protect public health. Public health campaigns aimed at promoting hygiene, sick leave, and awareness about norovirus will be key in combating the rise in cases and ensuring that the healthcare system is not overwhelmed. Through vigilance and action, it is possible to manage and mitigate the impact of norovirus on the population.
