WHO urges European vigilance against Zika virus
The reason for the high-level threat is the presence of Aedes aegypti mosquitoes.
COPENHAGEN: The World Health Organization urged Europe to be vigilant ahead of a possible summer outbreak of the Zika virus , especially in the Black Sea coastal areas of Georgia and Russia. "The likelihood of local Zika virus transmission, if no measures are taken to mitigate the threat, is ... high in limited geographical areas: the (Portuguese) island of Madeira (off Africa) and the northeastern coast of the Black Sea," WHO said.
The reason for the high-level threat in those areas is the presence of the Aedes aegypti mosquitoes, which carry the Zika virus that causes birth defects if contracted by a woman during pregnancy, the UN global health agency said.
Another 18 countries in Europe "have a moderate likelihood" of a Zika virus outbreak, WHO warned. "The overall risk of a Zika virus outbreak across the WHO European Region is low to moderate during late spring and summer," it said. That was largely due to the presence of another mosquito species in those countries, the Aedes albopictus, which is less likely to cause outbreaks than its cousin in Latin America and the Caribbean, according to research by the Pasteur Institute.
Within the "moderate likelihood" group, France, Italy and Malta had the top three transmission likelihood scores. The score was based on factors including climatic suitability for the mosquitoes, shipping and air connectivity, population density, urbanisation and history of previous outbreaks of virus es transmitted by insects or other animals.
"With this risk assessment, we at WHO want to inform and target preparedness work in each European country based on its level of risk," said Dr Zsuzsanna Jakab, WHO regional director for Europe. "We call particularly on countries at higher risk to strengthen their national capacities and prioritise the activities that will prevent a large Zika outbreak." (APP)
