Some horses in the province of Ferrara are positive for West Nile Disease
Posted on 16-09-2008
Region - The Institute Zooprofilattico of Teramo, National Reference Center for exotic diseases, confirmed the infection from West Nile virus in horses some teams located in the province of Ferrara. The Institute confirmed the presence of infection in wild birds from the same province, examined under the regional plan wildlife monitoring.
The West Nile is an infectious disease transmitted by mosquitoes, particularly the Culex genus. The virus is maintained into the environment through the continuous passage between mosquitoes and wild birds, which can also cause a significant mortality, and can occasionally be transmitted to different animals and to humans.
Typically in mammals the infection is asymptomatic, however, in horses can occur sometimes clinical symptoms of neurological type and also in the West Nile virus is responsible for clinical disease in a very small percentage of cases.
Both in men than in horses, however, the persistence and the amount of virus in the blood are not sufficient to cause further infections. Indeed man, as the horse is a guest so-called "final" and the mosquito can not in any way transmit the disease from person to person, from horse to horse or from horse to person.
In people the West Nile Disease is often asymptomatic (over 80% of cases) or mild symptoms aspecific, in rare cases (less than 1%), especially in elderly or immune deficiency, may submit forms with the most serious neurological (encephalitis or meningoencephalitis).
The horses play an important role as a signal of the presence of the virus in the territory, since it may show symptoms of infection.
The surveillance. While continuing their investigations on the presence of the virus in Ferrara, the Region and the Local Health Centre Companies, particularly that of Ferrara, have already put in place a systematic monitoring programme to deepen knowledge about the extent and scale of the phenomenon.
The programme was defined in collaboration with the Istituto Zooprofilattico experimental Lombardy and Emilia-Romagna, after the Centre reference Teramo and the Ministry of Health.
The first measures given Business Local Health Centre relate to veterinary supervision on horses and wild birds and human surveillance, particularly on workers in the stables affected by cases of infection in horses, and all suspected cases of viral encephalitis or meningoencephalitis observed in Regional.
Laboratory tests are carried out by the regional centre of reference for emergencies microbiological (CRREM) Polyclinic S.Orsola-Malpighi of Bologna. To date, was not reported any cases related to human infection from West Nile virus.
In addition to surveillance measures veterinary and human interventions are already programmed to monitor and fight all'insetto carrier. The Culex mosquitoes of the genus are abundantly present in rural areas and predominantly nocturnal habits.
In particular, in areas affected by the ongoing phenomenon, in addition to what has already been implemented in recent months under the regional plan to combat mosquito tigre and prevention of Chikungunya and Dengue fever, are planned interventions in pest with adulticidi During public events (festivals, fairs and the like) taking place in open areas, especially outside the urban centres and in the presence of vegetation or nearness of courses or collections of water.
It 'was then turned on entomological surveillance, providing for the capture of mosquito samples taken for analysis for the research of the virus. It recalls the importance of adopting measures to protect the individual from perforation of mosquitoes: this is the most effective means to reduce the risk of contracting the virus.
