A recent swissinfo article discusses the spread of ragweed (Ambrosia artemisiifolia) throughout that country. This allergy-aggravating plant, well-known in its native North America, is just reaching peak pollen-producing levels in Switzerland this month. The problem is so new there that allergists are still deciding what recommendations to make to current and potential patients. Estimates indicate that ragweed pollen will negatively impact about 14% of the Swiss population. Switzerland had been dealing with burgeoning ragweed populations for many years - the ISW first reported about it back in 2004.
