Epidemiology is defined as the study of A. where and when a disease occurs, and how it is transmitted. B. how a disease is transmitted. C. when a disease occurs. D. where a disease occurs.

What is the role of epidemiology? To learn which medicines are effective at killing pathogens. To learn how to treat and prevent various diseases. To learn which organisms cause disease. To learn what diseases can be caused by respiratory pathogens.

A patient acquires an infection by touching a contaminated door handle. Which mode of transmission best describes this scenario? droplet transmission direct contact transmission vehicle transmission indirect contact transmission

A dog develops a diarrheal disease after drinking water from a creek during a hike with his owner. Which of the following best describes this method of disease transmission? vector transmission vehicle transmission contact transmission There is not enough information to determine the mode of transmission.

Plague is transmitted through the bite of an infected flea. Which of the following best describes this mode of transmission? direct contact transmission vehicle transmission vector transmission indirect contact transmission

Which of the following would be considered a fomite? Which of the following would be considered a fomite? A fly Contaminated water A tick A toy

Which of the following would be considered a vector? Which of the following would be considered a vector? Water containing bacteria from fecal matter A fly carrying disease from fecal matter to food Water droplets that come from a sneeze from an infected individual Saliva that is transmitted between individuals during kissing

When aerosols containing pathogens spread disease from a distance of less than one meter, it is considered When aerosols containing pathogens spread disease from a distance of less than one meter, it is considered waterborne transmission. airborne transmission. contact transmission. vector transmission.

Which of the following is considered a major category of transmission of disease? Which of the following is considered a major category of transmission of disease? Vehicle transmission Contact transmission Vector transmission Contact, vehicle, and vector transmission

Which is an example of vehicle disease transmission? Which is an example of vehicle disease transmission? The presence of Listeria on undercooked chicken served for dinner The bite of a mosquito containing malaria The transmission of MRSA from skin to skin contact Touching a telephone with cold viruses on its surface

H5N1 avian influenza is widely considered to be the most serious global pandemic threat today, and is the target of much worldwide surveillance. Currently, the virus is not readily passed person-to-person, but reports that the virus may have recently entered (or re-entered) the swine population are of concern because of__________. A. humans typically come into more frequent contact with swine than with birds. B. possible reassortment of the influenza genome with swine and human strains. C. influenza more easily passing from pig-to-human than from human-to-human. D. possible antigenic drift.

The ideal bioweapon would be __________. The ideal bioweapon would be __________. one that is easily spread in aerosol form one that is cheap to produce, even if it is difficult to disseminate one that requires safety equipment to handle one with low morbidity
