Increasing Incidence of Anaplasmosis in the United States, 2012 Through 2016 Academic Article uri icon

abstract

  • Anaplasmosis is a tick-borne disease that is primarily caused by the rickettsial bacterium Anaplasma phagocytophilum. Anaplasmosis is a febrile disease with common symptoms, including headaches, fever, and lethargy, but it can cause serious organ failure and even death if left untreated. Human infections are reported annually to the Centers for Disease Control and Prevention (CDC) through the National Notifiable Diseases Surveillance System (NNDSS). This report analyzed the cases of anaplasmosis reported by the NNDSS from 2012 to 2016. In total, there were 15,778 reported A. phagocytophilum infections, and the incidence rate was 7.27 cases per million persons per year, with the number of reported cases increasing each year. The demographic group most affected was middle-aged and elderly white males. Infections were most abundant in the coastal northeast and northern midwest regions. Our study provides useful results for a basic understanding of incidence, distribution, and severity of A. phagocytophilum infections.
