To understand the scenario, we need to connect case growth to the basic reproduction number, R0. Option 1: 'The R0 value was less than 1' When R0 < 1, each infected person infects less than one other person on average, so an outbreak would tend to shrink over time rather than grow. Therefore, sustained increases in cases are unlikely under R0 < 1. Option 2: 'None of the above' This would be plausible only if none of the listed statements matched the situation; however, there is a statement that logically corresponds to rising cases, so this option is not consistent with epidemic dynamics. Option 3: 'The R0 value was greater than 1' If R0 > 1, each infected person transmits to more than one person on average, leading to exponential growth in cases in the absence of strong interventions. When weekly cases are rising, this is the hallmark behavior of R0 exceeding 1 in the early phase of an outbreak or when transmission accelerates. Option 4: 'The R0 value was 1' An R0 of 1 implies a steady state where cases neither grow nor decline on average; that would not explain a continued weekly increase in case counts. In summary, the pattern of ongoing increases aligns with transmission sufficient to push the population reproduction number above the threshold of 1, making sustained growth the expected outcome under R0 > 1. The other options describe conditions that would produce stable, shrinking, or unchanged case trajectories rather than persistent growth.
