De griepepidemie is voorbij, meldt het Rijksinstituut voor Volksgezondheid en Milieu (RIVM). Het aantal mensen dat afgelopen week met acute luchtwegklachten naar de huisarts ging is opnieuw gedaald. Ook het aantal afgenomen monsters waarin het griepvirus is aangetroffen, lag een stuk lager dan een week eerder.
Huisartsen namen afgelopen week bij negentien mensen met griepachtige klachten monsters af en in één van die monsters (5 procent) werd het griepvirus aangetroffen. De week ervoor was dat nog in 30 procent van de monsters het geval. Ook in de keel- en neusmonsters van deelnemers aan Infectieradar en in andere monsters zat minder vaak griepvirus dan vorige week.
Shifting Influenza Seasons and Viral Types
This year’s influenza epidemic began in mid-February, a few weeks later than the previous year. The previous epidemic started at the end of January and ended in March. This year’s epidemic was also shorter in duration.
Notably, influenza type A was the predominant strain circulating this season, whereas type B was more common last year. This shift in dominant strains highlights the unpredictable nature of influenza viruses.
Vaccine Effectiveness Remains Consistent
Despite variations between this year’s circulating strains and those included in the current season’s influenza vaccine, the vaccine’s effectiveness appears to be comparable to previous years, according to the RIVM. This underscores the continued importance of vaccination as a preventative measure.
The Future of Flu Surveillance
As of March 1, 2026, the Nivel has stopped reporting the number of patients visiting their general practitioner with flu-like symptoms. The RIVM can no longer report this data from this week onwards. However, data on the number of patients visiting their general practitioner with acute respiratory complaints remains available.
What Does This Mean for Future Epidemics?
The shift in surveillance methods indicates a move towards monitoring broader respiratory illness trends, rather than solely focusing on influenza-like illnesses. This approach may provide a more comprehensive understanding of the overall burden of respiratory diseases.
The shorter duration of this year’s epidemic, coupled with the changing dominant viral types, suggests that influenza patterns may be evolving. Continued monitoring and research are crucial to anticipate and prepare for future outbreaks.
Frequently Asked Questions
- Is the flu vaccine still recommended? Yes, the vaccine remains an important preventative measure, even with variations in circulating strains.
- What is Infectieradar? Infectieradar is a platform where participants can report respiratory symptoms, contributing to surveillance data.
- What type of influenza was dominant this year? Influenza type A was the predominant strain this season.
Pro Tip: Practicing quality hygiene, such as frequent handwashing and covering coughs and sneezes, can help prevent the spread of respiratory illnesses.
