2010 Statistics
Minnesota's three most common tick-borne diseases are
all carried by the blacklegged tick, often called the "deer
tick." During 2010, cases of these diseases reported to
the Minnesota Department of Health (MDH) totaled as
follows:
• Human anaplasmosis: 720 (more than double the 300-
plus cases in recent years).
• Babesiosis: 56, up from 31 in 2009.
• Lyme disease: 1,293, up 21 percent from 2009 and
slightly above the 2007 level of 1,239.

Minnesota Department of Health 2009 Budget
For the 2009 budget year, we received about $260,000
for West Nile virus (WNV)/arbovirus monitoring. Lyme
disease-specific funds were initially about $40,000, plus
a supplemental $38,000 expected this summer. We have
sought additional funding opportunities for our tick-borne
disease program and are awaiting word on these.
Reported case meeting the surveillance case
definition) for 2009:
-Lyme: 1,065 cases
-Anaplasmosis 317 cases
-Babesiosis 31 cases
Reported case meeting the surveillance case
definition) for 2008:
-WNV: 10 cases (an extraordinarily low year)
-Lyme: 1,043 (provisional)
-Anaplasmosis: 278 (provisional)
-Babesiosis: 28 (provisional)
Tick Life Cycle
Borrelia burgdorferi has been found in various blood-
feeding arthropods, only ticks have been shown to be
efficient at maintaining and transmitting these
spirochetes. Thus, we do not consider these other
arthropods to be part of the Lyme disease transmission
cycle. Unfortunately there are plenty of blacklegged
(deer) ticks in wooded portions of central, east-central,
and southeastern Minnesota.
