BEIJING, May 15 (China News Network) - Bern News: According to the Swiss Information Network, a fact sheet issued by the Swiss Academy of Sciences (SCNAT) on the 14th local time showed that climate change has led to a sharp increase in the number of patients with hay fever in the country.

It is reported that climate change not only causes many allergic plants in the country to release pollen earlier and more strongly, but also facilitates the spread of invasive and highly allergic plants such as ragweed.

According to the fact sheet, about 0.8% of the population in Switzerland was allergic to pollen in 1926. Today, it is estimated that about 20% of people in the country are affected by hay fever.

Therefore, researchers have proposed a series of measures to deal with this problem, including reducing air pollution, combating invasive species, limiting climate change, etc.
