Which of the following is a measure of disease frequency in a population?

Median

Mode

Prevalence

Variance

What does the term 'epidemiology' refer to?

Study of the distribution and determinants of health-related events in populations

Treatment of epidemics

Study of individual health

Study of plant diseases

Which of the following is NOT a factor contributing to the spread of infectious diseases?

Poor sanitation

Vaccination

Overcrowded living conditions

Air pollution

What is the basic reproductive number (R0) in epidemiology?

The average number of secondary cases produced by a single infected individual in a susceptible population

The number of cases present at a particular point in time

The total number of cases in a population

The number of susceptible individuals in a population

Which of the following is an example of a non-communicable disease?

Influenza

HIV/AIDS

Diabetes

Tuberculosis

Which statistical measure indicates the spread of disease in a population?

Mean

Median

Variance

Prevalence

What is the difference between incidence and prevalence?

Incidence is the total number of cases in a population, while prevalence is the rate of new cases.

Incidence is the rate of new cases, while prevalence is the total number of cases in a population.

Incidence measures chronic diseases, while prevalence measures acute diseases.

Incidence measures mortality, while prevalence measures morbidity.

Which of the following is a vector-borne disease?

Tuberculosis

Cholera

Malaria

Hepatitis A

What is herd immunity?

When a large proportion of the population is vaccinated, making it difficult for the disease to spread

A type of immunity developed by a single individual after recovering from a disease

The resistance of a population to a particular disease due to previous exposure

The immunity transferred from mother to child during pregnancy

#10

What is the difference between an epidemic and a pandemic?

An epidemic affects a larger geographic area than a pandemic.

An epidemic is more severe than a pandemic.

A pandemic affects a larger population across multiple countries or continents.

An epidemic is limited to a specific population, while a pandemic affects the entire world.

#11

What is an example of a common source outbreak?

Influenza spreading through a school over several weeks

An outbreak of measles due to contaminated food at a restaurant

HIV transmission through needle sharing among drug users

Malaria transmission through mosquito bites

#12

Which of the following is an example of a zoonotic disease?

Common cold

Rabies

Chickenpox

Malaria

#13

Which of the following is a common method used to control vector-borne diseases?

Improving access to clean water

Mass vaccination campaigns

Indoor residual spraying of insecticides

Providing antiretroviral therapy

#14

Which of the following is an example of a syndemic?

Influenza outbreak in a densely populated city

Simultaneous occurrence of obesity and diabetes in a community

Malaria epidemic in a tropical region

Spread of HIV among injection drug users

#15

What is the role of a case-control study in epidemiology?

To observe trends in disease prevalence over time

To identify risk factors associated with a specific disease by comparing cases to controls

To analyze genetic variations among individuals with a particular disease

To study the effectiveness of a new treatment for a disease
