San Mateo County: Lyme Disease Surveillance Winter/Spring 2005-06

Entomology Report March 2006, San Mateo County Mosquito Abatement District

Laboratory testing revealed ticks positive for the Lyme disease agent at 5 parks this year. Prevalence rates are similar to other parts of Northern California. Tick density varies widely between parks as shown in the map. The prevalence of infection at Huddart Park and Edgewood Parks is inaccurately low due to the small number of ticks tested to date. Further testing is needed at these sites.
