Neco Model Questions Vol1 2022 Agricultural Science Question 28
Practice objective / multiple choice question 28 from the 2022 Neco Model Questions Vol1 Agricultural Science examination.
In a herd of 150 cattle, a contagious disease has an incubation period of 7 days. During a 30‑day monitoring period the numbers of new cases recorded each week were: Week 1 = 5, Week 2 = 12, Week 3 = 18, Week 4 = 10. Assuming the disease spreads proportionally to the number of infected animals present at the start of each week, (a) estimate the basic reproduction number \(R_{0}\) using the data from weeks 2 and 3, and (b) using this estimated \(R_{0}\) and the recurrence \(I_{n+1}=I_{n}+R_{0}I_{n}\) (ignoring depletion of susceptibles), determine the proportion of the herd that would be infected after 6 weeks. Express the proportion as a decimal rounded to two decimal places.
