Interesting facts about rodents

Rodents play an ecologically important role in degrading organic matter, but they are also responsible for the contamination and destruction of food and fabrics, damaging structures, causing fires by gnawing wires, carrying and spreading pathogens via their bodies, parasites (fleas), and excrements.

They can be vectors of lung diseases that come from airborne particles, like histoplasmosis and hantavirus. Other important diseases related to rodents are the plague, which can be transmitted through the bite of fleas that infest rodents, rat bite fever, which can be transmitted through rodent bites, and leptospirosis, which can be transmitted through rodent urine. They are also responsible for spreading food-borne diseases, like Campylobacteriosis and Salmonellosis.

According to the World Health Organization (WHO), foodborne diseases, including Campylobacteriosi and Salmonellosis, are responsible for 33 million deaths a year worldwide.
