4.Compare: How does the spread of a foodborne pathogen compare to the spread of theperson-to-person pathogen you studied in activity A?A foodborne pathogen is much slower to spread than a person-to-person pathogen. The smallconfined room makes it easier and much faster to spread the virus. Foodborne only getsinfected by consuming contaminated food. On the other hand, a person-to-person pathogendoes not require that.5.Predict: How would you expect the spread of an airborne disease to be similar to anddifferent 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 isnumerous. One of the similarities is that they are all diseases. Another similarity is that they canall 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 diseasesspread by a victim breathing in pathogens in the air. This is different from how foodborne andperson-to-person diseases spread because foodborne diseases spread by being consumed andperson-to-person diseases spread by contact of two people. In conclusion all the types ofdiseases including foodborne, person-to-person, and airborne all posses numerous similaritiesand as well as numerous differences.6.Experiment: Run a few simulations with the airborne pathogen.A.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 thedisease in different parts of the room randomly.B.How does the spread of an airborne pathogen compare to the spread of foodborneand person-to-person pathogens?An airborne disease spreads randomly as the disease is in the air. It depends if the disease isinhaled. On the other hand, foodborne and person-to-person pathogens are predictable.Foodborne pathogens spread from contaminated food and person-to-person pathogens arespread from contact of infected people.7.Think about it: Suppose there is an infectious disease at a party. How could doctors tell if thedisease was foodborne, airborne, or transmitted person to person?Doctors could look for patterns to find out what type of transmission the pathogen inflicted. Forfoodborne, 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 pathogenswould be to go to the bathroom at the party and examine the towel for diseases or find out if
