Question

Fill in each blank with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase can be used only once.

Prevalence	Reservoir	Zoomotic	Pandemic	Endemic
Emergicing	Vector	Antibiotic	Virus	Epidemic
Vehicle	Incidence	Airborn	Vaccine

Epidemiologists monitor the total number of cases of infectious diseases in order to know its _____________________ within a population. This information can be used to determine whether preventative measures like that the use of a _______________ is currently effective or needs to be improved. If the current incidence rate of an infectious disease is similar to its previously observed incidence rate, then it is considered to be an _______________ pathogen within the population. However, many RNA viruses can evolve quickly and become more highly virulent strains that create an ________________ with a higher than expected incidence rate of disease. Because of their rapid evolution, they are also a significant source of novel __________________ diseases that have a __________________ origin and use a host cell receptor that is phylogenttically conserved among a broad spectrum of species.

Answer 1

Epidemiologists monitor the total number of cases of infectious diseases in order to know its PREVALENCE within a population. This information can be used to determine whether preventative measures like that the use of a VACCINE is currently effective or needs to be improved. If the current incidence rate of an infectious disease is similar to its previously observed incidence rate, then it is considered to be an ENDEMIC pathogen within the population. However, many RNA viruses can evolve quickly and become more highly virulent strains that create an EPIDEMIC with a higher than expected incidence rate of disease. Because of their rapid evolution, they are also a significant source of novel PANDEMIC diseases that have a ZOONOTIC origin and use a host cell receptor that is phylogenttically conserved among a broad spectrum of species.
