For millions of people in Switzerland, the arrival of spring is a bittersweet paradox. While the landscape transforms into a vibrant display of blooming flora, the air becomes saturated with invisible triggers that turn daily life into a struggle against sneezing, itchy eyes, and respiratory distress. In a country where roughly one in five people—approximately 3 million residents—suffer from allergies, asthma, or skin intolerances, the ability to predict and avoid these triggers is more than a convenience; it is a necessity for public health.
To address this growing burden, the Fondation aha! Centre d’Allergie Suisse is significantly upgrading its digital infrastructure to enhance pollen allergy tracking in Switzerland. By integrating high-precision data and user-centric tools, the organization aims to move beyond general forecasts toward hyper-local, actionable intelligence that allows sufferers to manage their symptoms proactively.
The centerpiece of this initiative is the modernization of the Pollen-News app, a tool that has served as a vital resource since its launch in 2011. Supported by funding from the Loterie Romande, the project is transforming how allergen data is visualized and delivered, shifting from static reports to a dynamic, real-time monitoring system designed for the complexities of the Swiss landscape.
Le pollen du bouleau est un fléau pour les personnes allergiques. Il provoque éternuements, nez qui coule, yeux larmoyants et, parfois, même de l’asthme.

The scale of the app’s utility is evident in its usage data. By the complete of last year, the tool recorded 5.4 million consultations, with a core base of 105,000 active users. But, general regional data often falls short in a country with Switzerland’s diverse topography, where a valley may have entirely different pollen concentrations than a nearby plateau.
The latest updates, which have been rolling out since late 2025, introduce a “pollen radar” map. Much like a meteorological radar for rain, this feature provides a visual representation of allergen levels across the entire national territory. To complement this, the app now employs push notifications that alert users to sudden spikes in pollen levels specifically within their place of residence.
From a clinical perspective, one of the most significant additions is the integrated symptom journal. By allowing users to log their daily observations, the app creates a longitudinal data set that patients can share with their physicians. This bridge between patient experience and clinical diagnosis is crucial for identifying specific triggers and tailoring immunotherapy or medication schedules with greater precision.
The Environmental Drivers of Rising Allergies
The push for better technology comes as the medical community observes a steady increase in the number of people suffering from respiratory allergies. This trend is not accidental but is driven by a combination of environmental and biological factors:
- Climate Change: Rising global temperatures have led to extended pollination seasons, meaning sufferers are exposed to allergens for longer periods each year.
- Air Pollution: Pollutants can interact with pollen grains, potentially making them more potent and increasing the likelihood of an allergic reaction.
- Lifestyle and Genetics: Changes in urban living and genetic predispositions continue to influence the prevalence of hypersensitivity.
A National Resource with Local Impact
While the Centre d’Allergie Suisse is headquartered in Bern, its mandate is strictly national, serving all linguistic regions of Switzerland. The organization functions as a comprehensive support system, operating an information line that handles more than 1,200 calls and emails annually from across the country.
Beyond digital tools, the foundation provides essential educational programming. These courses are tailored for different stakeholders, including private individuals, families managing children’s allergies, and healthcare professionals who require the latest evidence-based strategies for allergen management.
This wide-reaching infrastructure is made possible through strategic partnerships. The Loterie Romande plays a pivotal role, distributing its annual profits to nearly 5,000 public utility projects across French-speaking Switzerland, ensuring that modernization efforts for the app and the foundation’s website can continue through next year.

As the foundation continues its rollout of updates through 2026, the next phase of development will focus on further refining the website’s user experience and expanding the precision of the radar data. These updates are expected to be completed in stages over the coming months.
