Key Points

Seroprevalence increased to 1.6% in the past decade, highlighting a concerning trend.
A total of 25 positive cases were identified from 1,872 samples, indicating a significant change.
Residual sera analysis from individuals aged 10 to 64 years was conducted across Nova Scotia.
The findings may prompt public health responses to manage the risks of Lyme disease.

Implication

Analysis shows a rise in borrelia seroprevalence to 1.6% in Nova Scotia residents, suggesting a trend in tick-borne infections.

Abstract

Lyme disease (LD), a tick‐borne infection, is endemic in Nova Scotia. One decade ago, the seropositivity rate to Borrelia burgdorferi was 2/1855 (0.14%). In the current study, using residual sera representing ages 10–64 years, we demonstrate an increase in seroprevalence, to 25/1872 (1.60%), with the highest seroprevalence in the western area of the province.
