Leptospirosis is a zoonotic bacterial disease caused by *Leptospira* bacteria. It primarily affects animals like rodents and livestock, but humans can become infected through contact with contaminated water or soil. It is most common in tropical and subtropical regions worldwide.

It can change overnight. Be the first to know when it does.
Leptospirosis was first clinically described in 1886 by Adolf Weil. The causative bacterium, *Leptospira*, was identified in 1907. Historically, it significantly impacted agricultural workers and soldiers due to exposure in contaminated environments.
Leptospirosis spreads through contact with urine from infected animals (e.g., rodents, cattle, dogs). Humans become infected when contaminated water, soil, or food touches skin abrasions, mucous membranes (eyes, nose, mouth), or by ingesting contaminated water. Person-to-person spread is rare.
Contagious Period: Varies by disease
