The World Health Organization has identified more than 1,200 cases of severe allergic reactions after bites by the common white-spider.

In an update on the spider’s spread across Europe, the WHO said in February that there were now nearly 1,000 cases across Europe.

“We expect more cases to occur as we continue to assess the health impact of the spider in Europe,” WHO spokesman Mark Brown said.

The WHO said it expects the new cases to peak by the end of this year, with another 600 reported in the first half of 2017.

In the meantime, there are fears that the virus could infect people in Europe.
