Activity B (continued from previous page) Compare: How does the spread of a foodborne pathogen compare to the spread of the person-to-person pathogen you studied in activity A? a foodborne pathogen is much slower than a person-to-person pathogen. The small confined room makes it easier and much faster to spread the virus. Foodborne only gets infected by consuming contaminated food. On the other hand, a person-to-person pathogen does not require that Predict: How would you expect the spread of an airborne disease to be similar to and different from the spread of a foodborne disease and a person-to-person disease? The similarity of a airborne disease and both a foodborne and person-to-person disease is numerous. One of the similarities is that they are all diseases. Another similarity is that they can all infect and spread. These diseases not only have similarities but they also have differences. One of the many differences they have is the way they spread and infect. Airborne diseases spread by a victim breathing in pathogens in the air. This is different from how foodborne and person-to-person diseases spread because foodborne diseases spread by being consumed and person-to-person diseases spread by contact of two people. In conclusion all the types of diseases including foodborne, person-to-person, and airborne all posses numerous similarities and as well as numerous differences. Experiment: Run a few simulations with the airborne pathogen. What patterns do you notice in how the airborne pathogen spreads? There are no patterns on how the airborne pathogen spreads. People get infected with the disease in different parts of the room randomly. How does the spread of an airborne pathogen compare to the spread of foodborne and person-to-person pathogens? An airborne disease spreads randomly as the disease is in the air. It depends if the disease is inhaled. On the other hand, foodborne and person-to-person pathogens are predictable. Foodborne pathogens spread from contaminated food and person-to-person pathogens are spread from contact of infected people. Think about it: Suppose there is an infectious disease at a party. How could doctors tell if the disease was foodborne, airborne, or transmitted person to person? Doctors could look for patterns to find out what type of transmission the pathogen inflicted. For foodborne, they could make a chart and find out who ate the food and who got the disease or, they could microscope the food to find pathogens. A way for finding person to person pathogens would be to go to the bathroom at the party and examine the towel for diseases or find out if anyone touched another person or shared another persons item. To find airborne pathogens, doctors must first find both foodborne and person to person pathogens. If there arn’t any, then it leaves airborne the only option left. In conclusion, doctors could tell how a disease was transmitted through these methods. Download 335.71 Kb. Share with your friends:
