Rodents have been associated with numerous severe epidemics in the past, prompting microbiologist Hans Zinsser in the 1930s to write a book, Rats, Lice, and History, in which he documented the important role of rodents in epidemics
Discuss why rodent control is still desirable, even in an age when it is perceived that the "magic bullets" of chemotherapy and immunization to control infectious disease are readily available.
What will be an ideal response?
Answer: Rodents, among other animals, can serve as reservoirs and vectors of infectious diseases. Due to rodents' high reproductive rate, they can quickly propagate infectious diseases and in little time engender disease epidemics. Even if a disease is easily curable with a particular drug, it is still desirable to consider upstream efforts to eliminate the reservoir of an infectious disease, thus reducing human exposure to the disease agent. Currently emerging diseases such as hanta virus have a rodent reservoir and both plague and typhus can still cause significant numbers of cases worldwide.
