Influenza cases are rising rapidly across Norway, particularly in Oslo and central regions. The Norwegian Institute of Public Health reports an unusual early spike in seasonal flu activity.
Health monitoring shows more influenza than normal for this time of year, officials said in a statement. They recommend elderly residents and at-risk groups get vaccinated as soon as possible.
Laboratory testing has confirmed influenza presence in all Norwegian counties. The highest infection rates appear in Oslo, Møre og Romsdal, and Trøndelag regions.
This early surge suggests Norway might face a more challenging flu season than recent years. Health authorities typically expect peak flu activity later in winter months.
Why are cases spreading so quickly now? Cooler autumn weather and increased indoor gatherings likely contribute to the early transmission pattern.
Vaccination remains the most effective protection against severe influenza complications. Health services have sufficient vaccine supplies for the coming weeks.
