West Nile virus infection reported in Greece

28. July 2011.

The first case of West Nile virus (WNV) infection during 2011 was described as mild encephalitis by Centre for Disease Control and Prevention (KEELPNO) experts in announcements on Wednesday.


The West Nile virus-caused encephalitis was identified in Thessaloniki's Aristotle University (AUTH) Microbiology Laboratory and was diagnosed in an adult patient from the central city of Karditsa.

The patient is currently being treated at Larissa Hospital and his condition is improving, an AUTH Centre for Reference and Research on Arboviruses expert told ANA-MPA.

A KEELPNO team will visit Thessaly in central Greece to brief local people on protection measures. According to KEELPNO, more West Nile virus cases are expected in Greece during the summer, underlining that West Nile virus infection cases have been reported in other European countries as well.

The first West Nile virus epidemic in Greece was last summer with 262 cases reported, 191 of which had central nervous system manifestations, while 37 of the patients died.

The virus has been known for many years and the main route of human infection is through the bite of an infected mosquito. The infection caused is mild and most of the time asymptomatic with the elderly being more at risk of a central nervous system infection which, however, is easily curable, according to scientists.

ONGOING OUTBREAK OF WEST NILE VIRUS INFECTION IN HUMANS, GREECE, JULY TO AUGUST 2011

Available online: http://www.eurosurveillance.org/ViewArticle.aspx?ArticleId=19951

Date of submission: 22 August 2011

Between 16 July and 21 August 2011, 31 cases of West Nile neuroinvasive disease were reported from four regions in Greece. Of these, 17 occurred in districts that had not been affected in 2010. The reoccurrence of human cases in two consecutive years (following the large 2010 outbreak) and the spread of the virus in new areas suggest that West Nile virus is established in Greece, and its transmission may continue to occur in the future.

- snip -

In conclusion, the reoccurrence of human WNV infection cases in two consecutive years and the spread of the virus in newly affected areas, suggest that WNV is established in Greece and transmission may continue in the future. Intensified vector mosquito control programmes, along with ongoing public health education, integrated human and animal WNV surveillance to monitor the spread of the virus and implementation of blood transfusion measures are necessary to prevent transmission and control the disease.

- 7 november 2011 -

This weekly epidemiological report aims to present briefly the reported cases of West Nile Virus (WNV)
infection in Greece for the period 2011.

Data presented in this report are derived from the notifications of laboratory confirmed cases sent to the
Hellenic Centre for Disease Control and Prevention (KEELPNO) by their treating physicians. Laboratory data
are also included from i) the Reference Laboratory for Arboviruses, Aristotelian University of Thessaloniki
and ii) the Department of Microbiology, School of Medicine, University of Athens iii) the Department of
Microbiology, Infectious Disease Hospital of Thessaloniki.

The Department of Epidemiological Surveillance
and Intervention of KEELPNO undertakes a verification procedure through communication with the treating
physicians and the patients, if necessary.

From the beginning of 2011 until 04/11/2011 (16:00), 101 laboratory confirmed cases of WN infection were
reported, of which 76 presented with neuro-invasive disease (encephalitis and/or meningitis and/or acute
flaccid paralysis) and 25 cases with mild symptoms (fever and/or rash). Eight deaths occurred in patients
over 65 years of age with underline diseases (Table 1).

One out of the 75 neuro-invasive cases is considered
imported, as the patient was in Albania throughout the incubation period.

Another neuro-invasive case was
diagnosed in France. However, this patient was in Greece throughout the incubation period.
