In order to prevent the spread of the virus in Europe, experts urge to take additional measures to reduce risk threats, especially in those countries, the risk of the epidemic of the virus which is especially great. The world health organization stressed that, first and foremost, the virus is threatening those countries where the common mosquitoes of the species Aedes aegypti, its vector.

The disease was first identified in Uganda in 1947 and for a long time met only in areas of the Equatorial belt in Africa and Asia. But last year, the pathogen had reached South America, Central America and the Islands of the Caribbean, and then began to actively spread to new countries. About the first case of Ebola Zeke in Russia it became known in mid-February of the current year, and recently the number of Russians infected with the virus grew to three.

Symptoms of zika fever — headaches, joint pain and back pain, skin rash, chills and a slight fever. For the carrier of the virus, in most cases, not too dangerous, but if they infected a pregnant woman, this could have extremely negative consequences for the fetus. The virus causes microcephaly (reduced head size), and she, in turn, can lead to insufficient development of the brain and a number of other abnormalities. In mid-April, the head of the Centre for the control and spread of diseases, States Thomas Frieden said that the relationship between the virus and microcephaly proven conclusively.

For a long time it was believed that the virus is transmitted exclusively through the bites of mosquitoes. However, experts have already known several cases of sexual transmission of the virus from the partner returning from abroad: in early February about this case was announced in the United States in March in Chile, and in April in Canada. Despite the fact that such cases are exceptional, some experts believe that they remove the problem to another level, because if the virus is transmitted sexually, it begins to threaten, including people who do not intend to visit countries where mosquitoes live.
