Consider the following information to answer questions 15, 16, 17, 18, 19 and 20: A community contains 150,000 inhabitants and a subject infected with a highly contagious virus arrives. It is estimated that once a person is infected, they recover in approximately 10 days. However, for every 100 infected, 7 die. The rate of social interaction in this community is, in average, 3 people per inhabitant and the probability of contagion in such interactions is 16%.

a. If a fifth of the population is immune to the virus, what will be the total number of registered deaths once the epidemic ends?

b. Taking into account the information in question 15, what will be the total registered infections once the epidemic is over?

c. Taking into account the information in question 15, what will be the total registered infections if the social distancing and the use of masks reduce the probability of contagion by 30%?

d. If the population does not have immunity to the virus and the diet consumed by the average inhabitant reduces the duration of infection by 60%, what will then be the total number of infections recorded once? Will the epidemic ever end?
