The Reed-Frost model for the spread of an epidemic predicts that the number I of newly infected people is I = S(1 − e−rx), where S is the number of susceptible people, r is the effective contact rate, and x is the number of infectious people.† Suppose that a school reports an outbreak of measles with x = 8 cases, and that the effective contact rate is r = 0.3. If the number of susceptibles is S = 550, use the Reed-Frost model to estimate how many students will be newly infected during this stage of the epidemic.

The Reed-Frost model for the spread of an epidemic predicts that the number I of newly infected people is

I = S(1 − e⁻^rx),

where S is the number of susceptible people, r is the effective contact rate, and x is the number of infectious people.† Suppose that a school reports an outbreak of measles with

x = 8

cases, and that the effective contact rate is

r = 0.3.

If the number of susceptibles is

S = 550,

use the Reed-Frost model to estimate how many students will be newly infected during this stage of the epidemic. (Round your answer to the nearest whole number.)

The rate of increase of COVID-19 infection is directly proportional to the number of people infected and to the number people not yet infected. An isolated remote barangay of population 10,000 records its first case on June 15, 2020. After two days, 100 people are infected. Develop a model that predicts the number of COVID-19 cases in the barangay. How long will it take for 90% of the population to be infected? Assume that the virus persists in the person infected.
