CLINICAL MEDICINE

Detailed explanation-1: -Common methods of identifying additional cases (expanding surveillance) as part of an outbreak investigation include: Advising the public through newspapers, TV, radio, and the health department’s website to contact the local health department. Asking case-patients who they were with at the time of exposure (if known)

Detailed explanation-2: -Disease outbreaks are usually caused by an infection, transmitted through person-to-person contact, animal-to-person contact, or from the environment or other media. Outbreaks may also occur following exposure to chemicals or to radioactive materials.

Detailed explanation-3: -The primary reason for conducting outbreak investigations is to identify the source in order to establish control and to institute measures that will prevent future episodes of disease. They are also sometimes undertaken to train new personnel or to learn more about the disease and its mechanisms for transmission.

Detailed explanation-4: -Epidemiology is widely considered to be the basic science of public health. Epidemiologists count cases of disease (or injury), consider the distribution of the cases, and define the affected population.
