    Abstract:
    A passive surveillance program monitored ticks submitted by the public in Iowa from 1990-2013. Submitted ticks were identified to species and life stage, and Ixodes scapularis Say nymphs and adults were tested for the presence of Borrelia burgdorferi. An average of 2.6 of Iowa's 99 counties submitted first reports of I. scapularis per year over the surveillance period, indicating expansion of this tick species across the state. The proportion of vector ticks infected by B. burgdorferi increased over time between 1998 and 2013. In 2013, 23.5% of nymphal and adult I. scapularis were infected with B. burgdorferi, the highest proportion of any year. Active surveillance was performed at selected sites from 2007-2009. Ixodes scapularis nymphs collected at these sites were tested for the presence of B. burgdorferi, Anaplasma phagocytophilum, and spotted fever group Rickettsia spp. (likely representing Rickettsia buchneri). Nymphs tested were 17.3% positive for B. burgdorferi, 28.9% for A. phagocytophilum, and 67.3% for Rickettsia spp. The results of these surveillance programs indicate an increasing risk of disease transmission by I. scapularis in Iowa.
