Official health records reveal that in the year 2023, the metropolis documented 24 cases of leptospirosis, marking its zenith within a single annum. This stark contrasts with the preceding years, wherein an average of merely three cases per annum transpired between 2001 and 2020. To date this year, six instances have been officially reported.

The condition garnered attention two years prior, subsequent to reports of several canines purportedly succumbing to leptospirosis, conceivably contracted at the dog enclosure in McCarren Park, situated in Williamsburg.
