Why Is This Important?
Lyme disease is primarily caused by bacteria called ''Borrelia burgdorferi'' and is transmitted to humans through the bite of infected blacklegged ticks (or deer ticks, ''Ixodes scapularis''). Typical symptoms include chills, fever, bull's-eye rash, headache, and muscle pain. Lyme disease affects the central nervous system, heart, and joints in its advanced stages.
Definition
Incidence (new cases) of Lyme disease Data were captured by county of residence, not county of exposure.
Data Notes
The table displays the incidence rate and number of CDRSS reported cases of Lyme disease from 2007 through 2020 in New Jersey. Annual estimates of the resident population (July 1, 2007-2020) were used to calculate county incidence rates. National surveillance case definition was revised in 2008 to include probable cases. 2007 incidence rate was calculated using confirmed cases. Incidence rates from 2008 to 2020 were calculated using confirmed and probable cases.Data Sources
