They are often overlooked, but can produce millions of mosquitoes each season.
"Once they establish themselves here it would be more hard to control and maybe we'll see some diseases we haven't seen before", he said, adding the species can also transmit dengue fever and chikungunya - both of which can cause fevers, and headaches along with muscle and joint pain. The virus is spread by one simple bite by an infected mosquito. "The findings serve as a reminder to our community that risks can be greatly reduced by taking simple precautions".
The Ohio Department of Health says West Nile virus is most commonly spread by infected mosquitoes that can lead to severe fever, encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord).
In 2017, there were 203 cases of symptomatic Zika virus reported in the United States, according to the Centers for Disease Control and Prevention.
The Maryland Department of Health suggests staying inside during prime mosquito feeding hours, which are dusk and dawn.
Remove anything around your house and yard that collects water; just one cup of water can produce hundreds of mosquitoes.
West Nile has been detected in Elk Grove and across Sacramento and Yolo counties for the past 12 years. This is the first case in the county this year. In some cases, people will develop a fever, headaches, body aches, or joint pain, but they recover completely after a few weeks. And people should eliminate any sources of standing water.
Apply EPA-registered insect repellent containing DEET, picaridin, oil of lemon eucalyptus, IR3535 or para-menthane-diol products per the manufacturer's instructions.
According to OCCHD Epidemiologist Megan Holderness, those with the symptoms of West Nile should be tested by a physician.
Public health suggests wearing a long-sleeved shirt and trousers, especially in mosquito-prone areas, as well as wearing bug repellent containing DEET.
Even though the Los Angeles area has seen an increase in the number of people affected, the rest of the state has seen minimal numbers. "Survey your property after a rain to get rid of mosquito habitats", Phil Maytubby, OCCHD Public Health Protection Director, said.
The primary culprit is the northern house mosquito, which becomes infected when they feed on infected birds.
