Black-legged ticks (ixodes scapularis), also known as deer ticks, are responsible for most of the tick borne illnesses on Long Island. They’re best known as the primary vector for Lyme disease but they also cause babesiosis, ehrlichiosis, bourbon virus disease, Powassan disease, borrelia diseases, and an emerging public health threat called anaplasmosis.
Anaplasmosis is a bacterial infection that attacks the white blood cells, causing flu-like symptoms that can escalate into severe health complications or result in death. Also referred to as human granulocytic anaplasmosis, the disease was first identified in 1994. The number of cases rises each year and New York State is second only to Minnesota in the number of reported anaplasmosis cases.
The disease is now second only to Lyme disease in the percentage of state-tracked tick-borne disease cases it represents.
