Neco 2022 Biology Question 37
Practice objective / multiple choice question 37 from the 2022 Neco Biology examination.
In a closed community of 10,000 people a new infectious disease spreads. The transmission rate \(\beta\) is 0.3 per day and the recovery rate \(\gamma\) is 0.1 per day. Before the outbreak a vaccination programme immunises 40% of the population. After 5 days a public‑health campaign reduces the transmission rate by 20%. Using the SIR model, calculate the effective reproduction number after vaccination and after the campaign, and state whether the outbreak will eventually die out.
