Babesia microti is transmitted by Ixodes scapularis in which US regions?

• A. Southeast by Ixodes scapularis
• B. West by Dermacentor variabilis
• C. Northeast and Upper Midwest by Ixodes scapularis
• D. Southeast by Amblyomma americanum

Answer: (C)

Transmission of Babesia microti follows its tick vector, Ixodes scapularis. In the United States, this tick is most prevalent in the Northeast and the Upper Midwest, where babesiosis is endemic. The West uses different tick species, and Dermacentor variabilis is associated with other pathogens, not the primary transmission of Babesia microti. Amblyomma americanum is linked to other diseases as well. Therefore, the region where Babesia microti is transmitted by Ixodes scapularis is the Northeast and Upper Midwest.
