West Nile virus 'plaguing north-east Italy'


(ANSA) - Milan, August 24 - A new strain of West Nile virus
is becoming increasingly widespread in north-east Italy, health
researchers said Friday.
This virus, which was detected in a blood donor last month,
differs from earlier strains seen in outbreaks in 2008 and 2009,
says the study by the University of Padua.
The study, conducted in the Veneto region, suggests several
new strains are being found, and are starting earlier than in
previous years.
West Nile virus is a disease carried by mosquitoes which
can cause encephalitis.
The virus has emerged in recent years in Central and
Eastern Europe and the Mediterranean countries, and epidemics in
these areas are becoming increasingly frequent, says the study,
published in the peer-reviewed scientific journal
"This shows that the virus is able to winter in wetland
areas near rivers, where it probably has established its endemic
cycle", said Giorgio Palu, one of the authors of the study.
An increase in the virus demands stricter surveillance by
health authorities, he added.
