Persistently high levels of birch pollen!

Sunshine and temperatures of around 15 °C will dominate the weather in Burgenland in the coming days. This means ideal conditions for pollen counts and therefore a very high risk of intense allergic reactions.

The main culprit for the current pollen count is the pollen of the birchwhich is in full bloom in Burgenland. Its pollen has already led to very high levels over the Easter weekend and will remain at this level for the rest of the week.
In addition to birch, other members of the birch family such as hornbeam or hop hornbeam are ready to flower and can cause additional stress through cross-reactions, as the allergens of these plants are structurally very similar to those of birch.

The ash pollen season has already passed its peak in Burgenland. Therefore, only low to moderate pollen concentrations are to be expected in the ambient air.

In thermally favoured locations, the first pollen concentrations of grasses in bloom. These are very localised occurrences that can currently only cause low levels of pollution in the immediate vicinity. The forecast data for the grass pollen season currently indicates that the grasses will be ready to flower at the beginning of May. These data are still subject to major uncertainties at the beginning of the season and will become more precise over time.

In addition to the pollen types mentioned above, maple, yew, poplar, sour grasses and cypress plants are also represented in the pollen spectrum. However, they only have a very low allergenic potential.
