II. Narrative

The Delta Vector Control District (DVCD) seasonal laboratory staff ended their term for the season, following a decrease in service requests and outstanding property re-inspections. No strategic trapping took place in the month of November.

 

Arbovirus screening for West Nile virus (WNV), St. Louis Encephalitis Virus (SLEV), and Western Equine Encephalitis Virus (WEEV) did not take place in November. To date, a total of 2,785 mosquito samples have been tested with 143 samples testing positive for WNV and 37 positive for SLEV. No samples have tested positive for WEEV.

 

The invasive Aedes mosquitoes have continued to be found in some areas of the District. Inspections continued for service requests and high trap count areas. As of the end of November, a total of 3,178 inspections for invasive Aedes aegypti have been conducted, representing 2,611 unique properties. Of these properties, 729 had mosquito breeding sources at least once during the season. Additionally, 2,177 were inspected only once while 352 were inspected twice during the season. The remaining 82 properties were inspected three or more times.

 

Three oral presentations as well as three posters were accepted by the Mosquito and Vector Control Association of California (MVCAC) to be presented by the Laboratory staff at the upcoming MVCAC Virtual Annual Meeting from February 1-3, 2021. Also, three oral presentations were accepted to be presented at the next virtual Annual Meeting of the American Mosquito Control Association from March 2-5, 2021.

 

Throughout November, employees continued to complete the online screening of COVID-19 survey and take paid time off to seek test results when required. All employees at this time have tested negative. The District will continue to be proactive in keeping employees and the public safe, with no planned rollback of any of the safety precautions that have been put in place.

 

Staff continued to respond to service requests as needed. Vector Control Technician II’s left at the start of the month. Full time technicians began to clean, review and repair the vehicle fleet in November, as well as addressing the maintenance needs of the District grounds and fixing safety concerns. Ordering of parts and equipment began in earnest.

 

Cleaning out of outdated records began, in compliance with legal requirements and the records retention policy to clean up clutter around the administrative office and laboratory.

 

Staff appreciation luncheon, with a taco catering truck, took place on November 16th, and Paul Jobe and Tim Christianson were recognized and presented with their retirement plaques.

 

Administrative Assistant, Sheri Davis, attended a virtual training from the California Special District Association and is now certified as a Special District Board Secretary/Clerk.

 

The DVCD hosted the California Department of Public Health (CDPH) Vector Control Technician Certification exams on categories A-D on November 19th with 21 personnel from the Southern San Joaquin region taking the exams and among them were five from the DVCD. On the same day, the CDPH Biologist assigned to DVCD completed his semi-annual review of the DVCD and signed off on his inspection.

The District has a vacation policy that requires 24 hour notice in order to ensure the operational integrity of the workforce.  Sick leave for doctor, dentist and/ or family medical necessity also requires advance notice- in so much as it is possible.  Illness is unplanned and therefore unscheduled.  Attendance records for the current year are shown in the table.
