How is Leptospira transmitted to people?

Explanation:
Leptospira infection happens when the bacteria shed in the urine of infected animals contaminate water or soil, and how it enters the body depends on the integrity of surfaces it contacts. The main route is entry through mucous membranes (like the eyes, nose, or mouth) or through skin that is damaged or abraded. Intact skin generally provides a barrier, so simply touching water or soil without a break in the skin is unlikely to cause infection. While inhalation of aerosols and ingestion of contaminated water can occur in some circumstances, they are not the primary routes; the classic risk is contact with contaminated material that reaches mucous membranes or broken skin.
