LänsiNiilin

LänsiNiilin is a term that translates to "West Nile" in Finnish. It is most commonly associated with the West Nile virus, a mosquito-borne arbovirus that can cause illness in humans and animals. The virus is found in temperate and tropical regions across the world, including parts of Europe, Africa, the Middle East, and the Americas.

The West Nile virus is transmitted to humans primarily through the bite of an infected mosquito. Mosquitoes become infected when they feed on an infected bird, which are the natural hosts of the virus. While most human infections are asymptomatic or result in mild flu-like symptoms, a small percentage of people can develop severe neurological disease, such as encephalitis or meningitis, which can be fatal.

Prevention of West Nile virus infection focuses on reducing mosquito breeding sites and avoiding mosquito bites. This includes draining stagnant water, using insect repellent, and wearing protective clothing. Public health agencies monitor West Nile virus activity in bird populations and mosquito vectors to assess risk and inform the public.
