Homework Answers
a) e. 1.5 Transmission probability ratio is measure of risk of transmission from infected to susceptible populations through contact. In simulitis , the spread or transmission rate is very rapid thus probability of transmission will be higher. The higher value in the given options is 1.5. Hence i choose option e.
b) d. S, I and R . The three stages are based on the resistance level in individuals. susceptible individuals are those who are likely to be influenced by any harmful microbes or environment. infected individuals are those who become affected by these infectious microbes, mostly susceptible individuals become infected. recovered individuals are those individuals who become recovered from the microbes that caused disease by increasing the resistance to the microbe ( improve immunity).
c) a) Yes susceptible individuals are most vulnerable individuals. Hence a susceptible individual can easily become infected , by the exposure to this microbes.
d) b) No Recovered person gets high immune power , due to antibodies produced in the own blood of individual against those infectious microbes. So they have no chance of again getting infected.

Part A - SIR model for the spread of disease Overview. This part of the assignment uses a mix of theory and data to estimate the contact number c=b/k of an epidemic and hence to estimate the infection-spreading parameter b. The point is that once you know the value of b for a certain disease and population, you can use it in your model the next time there is an cpidemic, thus cnabling you to make predictions about the demand...
