In the past century alone, more than 10 million people have died from rodent-borne diseases. Although rodents are not major threats to our everyday health, it is justified to be concerned over the potential for rodents to transmit diseases. By their very nature and design, rodents make excellent “vehicles” for harboring and rapidly transporting diseases.
