a. Epidemic – fraction of the population having a disease at a specified time<\/p>\n\n\n\n

b. Incidence – number of new cases of a disease<\/p>\n\n\n\n

d. Endemic – a disease that is constantly present in a population<\/p>\n\n\n\n

e. Sporadic – a disease that affects a population occasionally<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The incorrect definition is:<\/p>\n\n\n\n

a. Epidemic – fraction of the population having a disease at a specified time.<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

An epidemic<\/strong> refers to a sudden and widespread occurrence of a disease within a specific geographic area or population that is in excess of what is normally expected. It does not specifically refer to the fraction of the population affected at a given time. Rather, an epidemic is about the sudden rise in the number of cases, typically indicating that something has changed in the environment, behavior, or a pathogen’s ability to spread.<\/p>\n\n\n\n

The correct definition of an epidemic is a widespread occurrence of an infectious disease in a community at a particular time.<\/strong> Epidemics typically focus on the increase in the number of cases of the disease<\/strong> rather than just a fixed fraction of the population.<\/p>\n\n\n\n

Breakdown of the other terms:<\/h3>\n\n\n\n
    \n
  • b. Incidence – number of new cases of a disease:<\/strong> This definition is correct. Incidence refers to the number of new cases<\/strong> of a disease that occur in a specified time period within a defined population. It measures how frequently a disease occurs within that population.<\/li>\n\n\n\n
  • c. Pandemic – a disease that affects a large number of people in the world in a short time:<\/strong> This is correct. A pandemic refers to an outbreak of a disease that occurs over a wide geographic area and affects a large portion of the global population. Pandemics often involve diseases that spread rapidly, such as the COVID-19 pandemic.<\/li>\n\n\n\n
  • d. Endemic – a disease that is constantly present in a population:<\/strong> This is also correct. An endemic disease is one that is regularly found and consistently present in a particular area or population. It can fluctuate in intensity but remains part of the normal health conditions for that population (e.g., malaria in certain regions).<\/li>\n\n\n\n
  • e. Sporadic – a disease that affects a population occasionally:<\/strong> This is correct. A sporadic disease occurs infrequently and irregularly, affecting individuals or small groups at isolated times. This pattern is different from the continuous or widespread nature of an epidemic.<\/li>\n<\/ul>\n\n\n\n

    In conclusion, the definition of “epidemic” in option (a) is the only one that is incorrect, as it misrepresents the concept of an epidemic by describing it as simply a fraction of the population having a disease.<\/p>\n","protected":false},"excerpt":{"rendered":"
