Norwegian health officials are sounding the alarm about the accelerating flu season. New data from public health authorities shows influenza cases are climbing steadily across the country. Positive test rates increased from 1 percent in week 40 to approximately 4 percent by weeks 43 and 44. The current week 46 marks the beginning of what experts predict will be the most intense phase of this year's outbreak.
The Norwegian Institute of Public Health confirms this year's flu season appears to be starting earlier than usual. Meanwhile, vaccination rates have surged dramatically in recent weeks. The vaccination curve peaked around week 43, matching last year's levels when approximately 300,000 people received flu shots.
After this peak, vaccination numbers flattened just as cough, fever, and sneezing symptoms began appearing widely. This pattern suggests many Norwegians followed health authorities' recommendation for early vaccination and already obtained protection.
Last year's season served as a serious wake-up call. 382 people died from influenza-related illnesses during that period. Over 8,000 required hospital treatment, far exceeding normal hospitalization rates for seasonal flu.
Health authorities specifically recommend vaccination for elderly citizens, pregnant women, and people with chronic health conditions. These groups face the highest risk of serious complications and worsening of existing conditions. The public health institute estimates approximately 1.7 million children and adults should receive the vaccine for optimal protection.
Most Norwegian counties hover near the national vaccination average. During the previous vaccination period between week 37 and New Year, about 23 percent of the population received flu shots.
Some regions stand out from this pattern. Preliminary data shows Western Norway currently lags behind other regions with the country's lowest vaccination rates. These early numbers could change as some counties traditionally vaccinate later in the season. Western residents might still catch up to other regions.
Last year, all counties reached their vaccination peak around weeks 42 or 43. Some areas experienced sharp increases toward this peak, while other counties showed more gradual, extended vaccination patterns.
Looking ahead, health experts anticipate rapid increases in flu cases, particularly in Oslo and Central Norway. All counties have already detected influenza cases, but infection rates remain highest in Oslo, Møre and Romsdal, and Trøndelag. School children currently represent the most infected demographic.
Kjersti Rydland, senior advisor at the Norwegian Institute of Public Health, delivered a clear message about vaccination timing. The flu vaccine provides optimal protection after 10 to 14 days. She emphasized the urgency of vaccination now to ensure effectiveness before the outbreak intensifies.
Last year's season combined influenza and COVID-19 hospitalizations, creating particular strain on healthcare systems. Health officials clearly want to avoid repeating that scenario. The current vaccination push represents Norway's best defense against another severe flu season affecting vulnerable populations and healthcare capacity.
