"While the prime West Nile virus transmission season is waning, I expect to continue to see an increase in the number of human cases in September and October because of the lag time between being bitten and getting a confirmed diagnosis. The risk of being bitten by a mosquito carrying West Nile Virus is still extremely high and will continue to be high until mosquitoes die off with the first killing frost," said Delta County public health director Bonnie Koehler.
"It's still not over for Delta County."
The Delta County Department of Health and Human Services is announcing that two more human cases of West Nile virus have been diagnosed in Delta County residents over the last two weeks.
This brings the 2013 Delta County total to 12 cases. In addition, a horse from the Delta area has also recently tested positive for the virus.
The 11th human case was recorded in a 40-to- 49-year-old female from the North Fork area of the county. She is recovering from a case of uncomplicated fever.
The 12th case was in a 50-to-59-year-old male also from the North Fork area. He is recovering from a case of uncomplicated fever.
The year-to-date county case-summary is as follows:
Cases are for five women and seven men; age range is 25-74; nine cases of uncomplicated fever, and one case of meningitis; seven cases from the North Fork, two from Surface Creek and three from the Delta area.
Eleven of the county's cases have been uncomplicated fever, and one other resulted in a hospitalization.
It is important to note that human cases being reported now were likely infected two to four weeks ago (mid-August). Significant numbers of human cases are still being reported daily, a trend that, given the recent, long period of hot weather, will likely continue for several weeks.
There is no licensed human vaccine to prevent WNV infections and the season will probably last for at least another month. Therefore, prevention strategies continue to be the key to reducing cases of human illness. Personal protective measures include the 4 Ds: DEET or other effective repellents; drain standing water; avoid being outside at dusk and dawn; and dress appropriately.
"These measures can be effective if they are followed consistently. Also, there is still time to vaccinate your animals," Koehler said.blog comments powered by Disqus
