They are always caused by bacteria

#10

What is the difference between an epidemic and a pandemic?

Epidemics affect a larger geographical area than pandemics

Pandemics are caused by bacteria, while epidemics are caused by viruses

Epidemics affect a larger number of people within a community or region, while pandemics affect a larger number of people globally

Pandemics are seasonal, while epidemics are not

#14

What is the difference between morbidity and mortality?

Morbidity refers to the number of deaths, while mortality refers to the number of illnesses

Morbidity refers to the rate of illness in a population, while mortality refers to the rate of death

Morbidity refers to the spread of disease, while mortality refers to its containment

Morbidity refers to acute illnesses, while mortality refers to chronic illnesses

#15

What is the primary goal of disease surveillance?
