The number of deer ticks submitted from each town and the number infected are summarized by town for the year 2001. If the town is served by a health district, its totals are included with the town listed in the second column. For example, Ansonia is served by the Naugatuck Valley Health District, which is located in Shelton. Any ticks that may have been received from Ansonia through the health district are included in the totals for Shelton. Those totals reflect the data for all the towns served by the health district. For a directory of local health departments and districts, see the state website at:  http://www.dph.state.ct.us/Local_health/localmap.asp?bar=1
