New York City Hit by Spike of a Rare Disease Spread by Rat Urine

New York City is coping with an uncommon outbreak of a uncommon, typically deadly illness unfold by means of rat urine, referred to as leptospirosis. At least 15 locals have contracted the bacterial illness in 2021 thus far, in keeping with well being officers, with most hospitalized and one individual useless because of this. It’s not recognized why circumstances have been extra widespread this yr, although hotter climate situations fueled by local weather change could also be an element.

Leptospirosis, additionally referred to as Weil’s illness, is caused by skinny, corkscrew-shaped Leptospira micro organism. It’s a zoonotic illness, which means that infections are transmitted to people by means of animals, on this case their contaminated urine. This can occur by means of direct contact with urine or when the urine contaminates the setting, comparable to our meals and water.

But within the U.S., it’s not often reported, with round 100 to 200 circumstances documented yearly, with most coming from Puerto Rico. In New York City, in keeping with well being division information, 57 circumstances of leptospirosis had been documented over a 15-year span from 2006 to 2020, or fewer than 4 circumstances a yr on common.

Though NYC did expertise historic flooding attributable to the tail finish of Hurricane Ida this yr, not one of the circumstances this yr appear to be associated to that occasion.
