Health officials reported another new case of human West Nile Virus in San Joaquin County this past week – neighboring Stanislaus reported five – and officials are reminding residents to continue to take precautions against mosquitoes that can carry the illness. “This year we have seen an overall higher population of mosquitoes than last year and also a higher population than the five-year average throughout the entire county,” noted San Joaquin County Mosquito and Vector Control District spokesman Aaron Devencenzi. Both the Escalon and Farmington areas have had mosquito samples test positive for WNV in the past week and the region has had both ground and aerial spraying in an effort to contain the population.
