Positive test for West Nile virus in mosquitoes

NUEVO

Nuevo is a rural community located east of Lake Perris and the city of Perris in Riverside County,

Most people infected with WNV have no

symptoms. Of those who become ill, mild

symptoms may include a fever, headache, body

aches, nausea, a skin rash on the trunk of the

body, or swollen lymph nodes. In severe cases,

inflammation of the brain, the membrane

around the brain, or both may occur. These

cases may result in high fever, headache, stiff

neck, disorientation, coma, tremors, paralysis,

and possibly death. Permanent neurological

damage may occur. The elderly and those with

weakened immune systems are at greatest risk

of illness associated with WNV.

The time between the mosquito bite and the

onset of the illness ranges from 5 to 15 days.

About 1 in 150 people who are infected with

WNV will require hospitalization.

Mosquitoes collected in the Nuevo area have tested positive for West Nile virus, the first time this year there has been a positive test in the western-county area served by the Riverside County Vector Control Program. It is not unusual for mosquitoes to test positive for West Nile virus, especially during the summer months. The sample of mosquitoes were collected June 17 near Mystic Field. The Department’s vector-control staff has intensified mosquito surveillance, as well as efforts to control adult and larval mosquitoes in these areas to reduce the mosquito populations and interrupt the disease transmission cycle. Residents may get rid of unwanted tires and other debris that can collect water. Even small amounts can be a breeding site for hundreds of mosquitoes.
