Practice objective / multiple choice question 50 from the 2019 Neco Agricultural Science examination.
In a poultry farm, a contagious disease spreads with a transmission coefficient \(\beta = 0.8\) per day per infected bird. Infected birds recover at a rate \(\gamma = 0.2\) per day and die from the disease at a rate \(\mu = 0.05\) per day. Assuming no births, (i) calculate the basic reproduction number \(R_0\), (ii) state whether an epidemic is expected, and (iii) determine the minimum proportion of birds that must be vaccinated with a perfect vaccine to prevent an epidemic.
