The West Nile virus, caused by mosquito bites, is spread worldwide, including in the U.S and, the average of cases is higher during the hot season. This mosquito-borne disease affects one in five people infected, and one in s hundred and fifty people develop symptoms. The CDC further explains the symptomatology of the West Nile infections: fever, common cold symptoms, headaches, joint pain, diarrhoea, vomiting and local rashes. The good news is that most infected people develop no symptoms, and most of those who do, recover completely. Those less unfortunate who do develop severe cases might need hospitalisation. Acute symptoms such as encephalitis or meningitis have been reported, but researchers concluded it is more common for those over 60 or immuno-compromised people.
Mosquitoes from Benton and Walla Walla County tested positive for West Nile virus
Recent reports have detected the virus in mosquitoes in several parts of the U.S, such as Kennewick, Richland and Walla Walla County. The Benton-Franklin Health District announced that there had not been identified any West Nile case in humans this year. Until air quality improves, it is impossible to use chemical substances such as mosquitoes against the mosquitoes. The infection is most common in animals such as birds and horses. Fortunately for horses, there is a vaccine available against the West Nile virus.
With no available vaccine for humans, the Benton Country Mosquito Control announced they are keeping things under control by using fog treatment in different locations. However, due to wildfires, they will try to limit their fog treatment impact. The advice given is to use repellent and avoid going out without proper clothes during dusk and dawn. The West Nile virus is just one of many infections humans can get after a mosquito bite.
