The Twin Falls County Pest Abatement District (TFCPAD) has collected at least one mosquito carrying West Nile virus in a trap along the Jerome and Twin Falls county line.
Citizens can view a mosquito trapping and spraying map depicting areas where WNV has been detected and subsequently sprayed to reduce the adult mosquito population.
"These positive mosquitoes are a reminder that West Nile virus may be present in areas around the state", said State Health Officer Jeanne Ayers. Residents are urged to take the necessary precautions to protect themselves from mosquito bites.
"The virus has established itself in Greece through migratory birds and we are recommending that everyone takes personal protective measures such as wearing long sleeves, avoiding places with stagnant water and using mosquito nets and repellent", she said.
The department says maintaining vigilance to prevent exposure is extremely important.
The department says common symptoms for the virus include fever, nausea, headache and muscle aches.
In some cases, infected people go on to develop meningitis, encephalitis or paralysis - and there is no treatment or vaccine.
WNV is spread to people through the bite of an infected mosquito and is not transmitted person to person.
The Clay County Health Department is conducting surveillance for West Nile virus throughout the county.
Limit time outdoors at dusk and dawn, when mosquitos are most active. More severe infections may involve the central nervous system.
Wearing loose-fitting clothes with long sleeves and trousers.
Installing screens on all windows and doors.
Checking for, and draining, any standing water around your home every three to six days.
