Neco Model Questions Vol1 2023 Agricultural Science Question 20
Practice objective / multiple choice question 20 from the 2023 Neco Model Questions Vol1 Agricultural Science examination.
Animal Diseases: In a cattle herd, a contagious disease has a transmission coefficient \(\beta = 0.8\) week\(^{-1}\). The average infectious period is 2 weeks, giving a recovery rate \(\gamma = 0.5\) week\(^{-1}\). The disease also causes a mortality rate of \(\mu = 0.1\) week\(^{-1}\). The basic reproduction number is given by \(R_{0}= \frac{\beta}{\gamma + \mu}\). Compute \(R_{0}\) (to two decimal places) and state whether the disease is expected to spread in the herd.
