The World Health Organisation (WHO) said the Zika virus could spread to Europe this summer, although the likelihood of an outbreak is low to moderate. Areas most at risk are those where Aedes mosquitoes spread the virus: the Black Sea coast of Russia, Georgia, and Madeira. Countries with a moderate risk include Spain, France, Italy and Greece. UK risk is low. The WHO is calling on countries to eliminate mosquito breeding sites and ensure that people, particularly pregnant women, have information on the potentially harmful consequences of the disease.
