Deadly Mosquito-Borne Menace on the Rise: West Nile Virus Spreads Across Slovenia with 3 Confirmed Cases
West Nile Virus Infection Cases Confirmed in Slovenia
The National Institute of Public Health (NIJZ) has confirmed the first three cases of West Nile virus infection in Slovenia this year. The cases were reported in the north-eastern part of the country, specifically in Pomurje and Podravlje.
West Nile virus was first discovered in 1937 in northwestern Uganda. Slovenia has experienced infections with the virus in the past, with one case recorded in 2013 and 2017, and five cases in 2018.
Global Outbreaks
This year, cases of West Nile virus infection have been reported in several EU countries, including Croatia, Italy, Austria, Hungary, Spain, France, Bulgaria, Germany, and Romania. Infections have also been reported in Serbia, Albania, and Kosovo.
Transmission and Symptoms
West Nile virus is primarily transmitted through mosquito bites, making it more common during warmer months when mosquitoes are most active. In rare cases, the virus can be transmitted through transfusions, tissues, or donated organs.
About 80% of people infected with the virus do not exhibit symptoms. However, a small proportion of infected individuals may develop a short-term illness with symptoms such as:
- Fever
- Malaise
- Headache
- Rash
- Muscle pain
The incubation period for West Nile virus typically lasts between 3 to 14 days.
Risk Factors and Treatment
People over 50 and those with weakened immune systems are at a higher risk of developing a more severe course of the disease. In most cases, immunity to the virus is long-lasting after infection.
Mild forms of the disease do not require treatment, but more severe cases often require hospitalization. There are no effective antiviral drugs available, and treatment is primarily symptomatic and supportive.
Prevention
Since there is no vaccine available to prevent West Nile virus infection, the most effective measure to reduce the risk of infection is to prevent mosquito bites. This can be achieved through various means, including:
- Wearing protective clothing
- Using insect repellents
- Avoiding peak mosquito hours
- Eliminating standing water around homes
