Local health officials Friday announced the caseload has jumped from 47 on Tuesday to the current number of 58.

Many of the new cases are in the north area which was recently sprayed with mosquito pesticide from the air. But County Health Officer Dr. Glennah Trochet says it’s still too early to see any results from those treatments.

“We have not had the opportunity yet to see the affect of the spraying that occurred last week. Many of these cases - the incubation period for West Nile virus is 4 days to 14 days so the cases that are being reported this week are likely people who were infected the week of the spraying or the week before that.”

The Sacramento–Yolo Mosquito and Vector Control District had planned to start aerial spraying in southern Sacramento County but strong Delta winds grounded their aircraft all week.

District officials say until they’re able to get their planes off the ground again, it’s important that people protect themselves from mosquito bites.
