58-year-old infected hospitalized Nile fever

Fear all along Veneto for the return of the mosquitoes carriers of the virus of the Nile Fever [VIDEO] (West Nile). The mosquito, responsible for the transmission of infection, hit a 58-year-old man from Rovigo, who was admitted to the hospital's infectious diseases department. The patient was struck by encephalitis caused by the severe form of neuroinvasive disease. Many regions of Veneto affected by the problem and, for the moment, only the provinces of Vicenza and Belluno, did not seem to have suffered from their summer invasion. These are the mosquitoes belonging to the particular species 'Culex Pipiens', considered extremely infectious and dangerous for possible transmission of the virus to humans

Mosquitoes infected with West Nile: the case of contagion in Rovigo

The first outbreaks of mosquito killer this year were reported in Verona, twenty days ago and later in some areas of Padua. The news that has aroused the most concern in the population is certainly that of the first case, concluded at the hospital, thanks to an badysis and appropriate clinical investigations, of the contagion of a citizen de Rovigo [VIDEO] admitted to the Department of Infectious Diseases. The patient developed a more severe form of neuro-vegetative disease. The contagion of this form is not, statistically, very common but when you meet it, it is very important, by the medical staff, to suddenly recognize the type of infection in order to start, as soon as possible , appropriate and effective treatments.

In about 80% of cases, the virus contracted in its most dangerous form manifests itself asymptomatically and, therefore, its clinical identification is not easy and immediate. Complications, especially in the presence of elderly people or with debilitating diseases, can also lead to serious complications of the neurological system, such as those related to encephalitis or meningitis

West Nile Virus: Symptoms and Prevention

Cases of Nile fever, caused by infected mosquitoes, date back about 10 years, following confirmation of the positivity of the virus in question, in blood samples from an asymptomatic donor of Rovigo . In most cases, the infection is not accompanied by obvious symptoms and organic consequences. Only in a small percentage of cases (approximately 20%) can mild symptoms occur in mosquito-infected patients, such as headache, nausea, vomiting, mild temperature increase, and rash.

The most dangerous form, as we have seen, is rather neuroinvasive or vegetative, which can also lead to possible complications of the patient's neurological system. Contagion is not direct, ie person-to-person, but occurs only through the bite of the infected mosquito or through the transplantation of organs and blood transfusions of people already affected by the infection. Disinfestation interventions aimed at attacking not only insects but also their larvae are certainly intended to mitigate the uncontrolled development of the insect. The recommendations to citizens are, as usual, those to avoid the stagnation of rainwater or to empty them systematically. The use of mosquito nets or other appropriate devices to prevent access of insects to the home are certainly important steps to take, in addition to the use, on the skin, of substances specific repellents.
