High-Yield Explanation
Leptospirosis is the bacterial disease that has been associated with the 3 "Rs" i.e., rats, ricefields, and rainfall. Leptospira infects various animals including rats and other rodents, domestic livestock, and household pets. Animals excrete leptospiras in urine, which contaminates water and soil. Swimming in contaminated water or consuming contaminated food or drink results in human infection. Leptospira are tightly coiled, thin, motile, flexible spirochetes with very fine spirals, one end is often bent forming a hook. Human infection usually results from the entry of organism through breaks in the skin and mucus membranes.
