West Nile infection is an infectious disease produced by the West Nile virus (VWN), which is transmitted by mosquito and interuman puncture by vertical transmission, blood transfusion, transplantation. The risk period for transmission of the disease is May to November.
Favorable factors for the occurrence of cases / epidemics are climatic changes – high temperatures, heat waves following heavy rains, and increased passenger and freight traffic.
Controlling the disease can be achieved by vector control measures and population education in self-protection.
The recommendations for the population are as follows:
- to avoid exposure to young men, wearing long-sleeved clothing and long pants;
- to use repellent chemicals against youths on uncovered parts of the body;
- to prevent the mosquitoes from entering the house (window nets);
- to use insecticides in the dwelling / around the dwelling, the use of permethrin-impregnated bands in areas where it is not possible to avoid mosquitoes entering the sleeping room;
- the use of permethrin, pyrethroid with insecticidal properties, application on clothes (impregnation of military clothing, impregnation of workers working night in the field), mosquito nets, tent walls or other materials but not on the skin.
About 80% of the infected person has no symptoms, but if you identify the signs and symptoms below, the health care professionals of the Ministry of Health recommend you to get to the nearest medical clinic:
- intense headache
- muscle pain
- skin rash
In severe cases that most frequently affect people over 60 years of age with chronic conditions (cancer, diabetes, hypertension, chronic kidney disease), other symptoms may also occur:
- neck stiffness
- increased sensitivity to light
- chronic fatigue
- muscle weakness
Surveillance of West Nile virus has begun since June. There is no specific antiviral vaccine or treatment for West Nile virus infection.
The Prefect Institution – Mureş County sent an address to the mayoralties on the need to take measures for the surveillance and reduction of the populations of young people.
At national level there is an increase in the risk of West Nile virus infections, which has also been aggravated by the meteorological phenomena of the last period.
In this context, local authorities must organize disinfestation activities with companies licensed for this purpose, focusing on areas with rich vegetation, parks, riverside areas.
Town halls have to take action for remediation / drainage of ponds and accumulations of water as a result of heavy rains as well as to inform the population about the need to remove waste water from households or underground.
"In view of the increase of the mosquito population in several areas of the county, as well as the notifications we have received in this respect, we have convened an analysis session with the responsible institutions in the county: the Public Health Department of Mureş County, the Inspectorate for Emergency Situations "Horea" of Mureş County, Mureş County Veterinary and Food Safety Directorate, Mureş County Department of Agriculture, National Agency for Land Improvements – Mureş Territorial Land Improvement Branch, Mureş Basin Water Administration, Mureş Phytosanitary Office, Agency for Environmental Protection Mureş, National Environmental Guard – Service of the Mureş County Commissariat, in which we analyzed the measures to be taken to reduce these populations. I have warned, through a circular, the heads of territorial administrative units on the measures they have to take in each locality to combat mosquitoes. It is the institutions with responsibilities in the field to control the way in which the mayors and the local councils follow these recommendations, "said Mureş County Prefect, Mircea Dusha.
