The Netherlands is currently experiencing a significant surge in influenza cases, prompting hospitals to postpone non-essential surgeries and raising concerns about the potential spread of the virus during upcoming Carnival celebrations. The National Institute for Public Health and the Environment (RIVM) officially declared an epidemic on Wednesday, February 11, 2026, marking a relatively late start compared to the previous two winters.
The current outbreak is primarily caused by influenza A, subtype H3N2, which has been circulating since October 2025 and has become the dominant strain. While some initial reports referred to this variant as a “super flu” due to its impact in England, RIVM spokesperson Harald Wychgel stated, “This story seems exaggerated. The flu season in the Netherlands has not started earlier than usual.”
Hospitals are already feeling the strain, with increased patient numbers leading to capacity challenges. The approaching Spring break and Carnival festivities are expected to further accelerate the spread of the virus, as large gatherings provide ideal conditions for transmission. This situation highlights the ongoing challenges of managing respiratory illnesses and maintaining healthcare capacity during peak seasons.
Jean-Luc Murk, a virologist at the Elisabeth-Tweesteden Hospital in Tilburg, explained that Carnival celebrations contribute to the spread of illness due to close proximity, shouting, and singing. He also noted that alcohol consumption and lack of sleep during the festivities can weaken immune systems, making individuals more susceptible to infection. “With Carnival, we often receive sick. The festival falls not only in the middle of flu season, but also in the period when diarrhea viruses are common,” Murk said.
While complete prevention is difficult, experts offer several recommendations to reduce the risk of infection. The most important measure, according to Murk, is frequent handwashing with soap and water. He also suggests using hand sanitizer as an alternative, although it may not be effective against all viruses. Avoiding touching the eyes with unwashed hands and limiting close contact, such as kissing, are also advised.
Maintaining adequate sleep, staying hydrated, and consuming a healthy, balanced diet rich in vitamins, fiber, and protein can also help bolster the immune system. Murk acknowledged that getting sick is a part of life, but emphasized that these steps can minimize the chances of infection. “Maybe we should just accept that,” he said. “Getting sick is part of life.”
The RIVM reports that the current influenza vaccine appears to be functioning as effectively as in previous years. Despite the current surge, officials have not issued a widespread panic alert, but are closely monitoring the situation and urging individuals experiencing flu-like symptoms to stay home, particularly those planning to participate in Carnival celebrations. This guidance aims to curb further transmission and protect vulnerable populations.
