The world health organization announced that the zika fever is no longer a global threat. We will remind that state of emergency was in effect from 1 February.
Who officials, however, emphasize that the zika virus continues to pose a danger. It was first found in Brazil, and later spread around the world – we know about cases of infection with Sicoi 60 countries.
Scientists emphasize the need to continue to study the virus itself and the associated contagion effects. There is still no vaccine that protects against contamination – studies in this area should also be pursued.
Many experts, however, surprised at the who’s decision, calling it “unreasonable.” They believe that this will lead to the fact that research aimed at the study of the virus will be maintained weaker. In addition, despite the fact that the virus began to spread slowly, the threat of epidemic persists.
The carrier of the virus Aedes aegypti mosquito. Recently, scientists have found that carry dangerous viruses and mosquitoes of the species Culex quinquefasciatus, which are common in Brazil quite extensively. Their population is 20 times the size of the population of Aedes aegypti.
Infection with the virus can cause a range of neurological disorders, e.g. Guillain-Barre syndrome, and infection during pregnancy causes fetal microcephaly is a serious defect. Everything in the world (most of them in Brazil) was about 2300 cases of babies born with microcephaly associated with the zika virus. In reality, such cases are much more. Microcephaly was recorded in 28 countries, and Guillain-Barre syndrome was detected in 19.
