Five cases of West Nile virus infestation this season



V. Stoica

The rural area – where disinfestation in the public domain is a real luxury – seems to be preferred by mosquitoes infested with West Nile virus if we take into account cases from the beginning of the season where insects can spread various diseases through the transfer of
According to the National Center for Communicable Disease Control and Control, in the 2018 season, between May 2 and July 24, there were five cases of West Nile infection, but no death occurred during the reference period. According to the same source, all five confirmed cases were recorded in males, four of the five being in rural areas.
Prahova Public Health Directorate submitted at the end of last week what measures should be taken to reduce the possibility of infection with West Nile virus: avoiding contact with mosquitoes, wearing apparel with long sleeves and long pants or by the use of commercially available mosquito repellents by fitting nets to windows to prevent mosquitoes from entering homes, but also by removing ponds around households or places where animals are being grown, and there may be lakes with standing signs of mosquito propagation
Signs that may indicate West Nile infection are fever, myalgia, headache, anorexia, nausea, vomiting, maculopapular cutaneous rash. DSP Prahova states that less than 1% of patients experience neurological manifestations of meningoencephalitis by affecting the central nervous system. Neuroinvasive disease is characterized by high fever, headache, neck revulsion, disorientation, coma, tremor, seizures, muscle weakness, loss of vision, loss of sensitivity and paralysis, a severe progression, and neurological sequelae may manifest in the long run. In these cases, mortality is 10%, among the risk factors for developing neurological manifestations being over 50 years of age and immunodepressed patients. Clinical symptoms occur after an interval of 2-14 days from the time of infection
According to the data provided by the representatives of the Prahova Public Health Department, the natural transmission cycle of the disease involves the birds (the natural reservoir of the virus) and the mosquitoes ) that transmit stinging infection to humans and animals (considered as accidental hosts). The same source states that although in most cases transmission is by mosquito nettle, in a very small number of cases the West Nile virus (VWN) can be transmitted from person to person through transfused blood, organ transplantation, breastfeeding and even during pregnancy from mother to fetus
