“Prevalence” can be defined as:
a. The proportion of new cases of a disease that occurs in a population at risk over a set period of time.
b. The number of cases of disease in a population.
c. The number of new cases of a disease that occurs in a population annually.
d. The proportion of the total population that has a disease at one point in time.
e. The number of cases of a disease at the midpoint of any year.
Which of the following statements are correct? *
Extended trade territories, increased travels as well as effects on ecosystems due to increased
human population raised the emergence and spread of infectious diseases leading to higher
risks pandemics.
Epidemics that become unusually widespread and even global is referred to as a pandemic.
Major pandemics that have afflicted humankind throughout history include those caused by
plague, cholera, influenza and coronavirus diseases
Because of the lessons learned in the control and management of the SARS-CoV-2 infection,
pandemics will occur less frequently in the future.
