A certain disease has a basic reproduction number (R0) of 3. If one infected person enters a population of 1000, how many people could potentially be infected after one generation? (2021)
Step 1: Understand what R0 means. R0 (basic reproduction number) indicates how many people one infected person can infect.
Step 2: Note the value of R0 given in the question, which is 3.
Step 3: Since R0 is 3, this means that one infected person can infect 3 other people.
Step 4: Calculate the potential number of new infections by multiplying the number of infected people (1) by R0 (3).
Step 5: Perform the calculation: 1 infected person * 3 = 3 potential new infections.
Step 6: Conclude that after one generation, 3 people could potentially be infected.
Basic Reproduction Number (R0) – R0 represents the average number of secondary infections produced by one infected individual in a completely susceptible population.
