Medical Research: What are the main findings of the study that were just published in Ticks and Tick-borne Diseases?
Dr. Salkeld: The primary findings of this new study show that western black-legged ticks, which can transmit Lyme disease, are active throughout the year in Northwest California, making the threat of Lyme disease year-round phenomenon.
More specifically, my colleagues from California Department of Public Health Vector-borne Disease Section and University of California, Berkeley and I found that the activity of Western Black-legged ticks (Ixodes pacificus), which are the ticks most commonly known to carry Lyme disease (caused by Borrelia burgdorferi) in Northwest California, is largely predictable and year-round. In general, tick larvae (newly hatched immature ticks) are active April to June, and sometimes activity extends into October, while adult ticks are active from October to May. Nymphal ticks (the tick stage following larvae and preceding adults) are active from January to October but peak from April-June. This is important because nymphs are responsible for most Lyme disease infections.
