West Nile virus detected in south S.J. County

STOCKTON — The surveillance program of the San Joaquin County Mosquito and Vector Control District has confirmed that additional mosquito samples tested positive for the West Nile virus in the Ripon area. A dead bird was also found to have the virus in the southern portion of the county, the district said.

Mosquitoes testing positive for the virus were found in the Ripon area earlier this month. Mosquito and Vector Control in Sacramento and Yolo counties have also found mosquitoes with West Nile virus in Isleton and Zamora, and a dead crow with the virus in the Rosemont area.

West Nile virus can be transmitted to humans, but most cases are mild. Symptoms include fever, headache, body aches, skin rash and swollen lymph nodes. More severe symptoms can include a stiff neck, sleepiness, disorientation, coma, tremors, convulsions and paralysis. Anyone experiencing severe symptoms should seek immediate medical attention.

To protect against mosquito bites, eliminate standing water on your property, avoid spending time outside at dawn and dusk when mosquitoes are most active, use mosquito repellent approved by the EPA and wear protective clothing. Anyone with horses should consult with their veterinarian about WNV vaccinations.
