Reported Cases of Lyme Disease in Manitoba

In 2009, Lyme disease became nationally reportable.  National definitions for confirmed and probable cases were developed by the Public Health Agency of Canada (PHAC), whereby Canadian jurisdictions will consistently report both confirmed and probable cases.  

Case Classification	2009	2010	2011
Confirmed Case *	1	7†	7
Probable Case *	4	5	4
Other **	6	4	4
Total Reported ***	11	16	15

As of March 19, 2012     

* Confirmed and probable cases of Lyme disease became reportable to the Public Health Agency of Canada (PHAC) in 2009.  Manitoba has adopted the national case definitions for reporting. National case definitions are available at: www.phac-aspc.gc.ca/publicat/ccdr-rmtc/09vol35/35s2/Lyme-eng.php

** Cases listed as “Other” include those that have been reported to Manitoba Health either by a physician or lab report, but do not meet the national case definitions for a confirmed or probable case of Lyme disease.

*** Some reported cases are currently under investigation; these cases will be classified when the investigations are complete.

^† One of these cases was an exposure prior to 2010.
