Question

A town of 20,000 has 80 reported cases of influenza in one week. Calculate the weekly incidence per 1,000 population and assess whether a threshold of 4 cases per 1,000 per week has been exceeded. Show your work.

Accepted Answer

4 per 1,000 per week; the threshold of 4 per 1,000 has been met and warrants heightened surveillance and consideration of control measures.

Answer

0.4 per 1,000 per week; the threshold has not been met and no action is needed.

Answer

Incidence cannot be calculated without knowing the age distribution of the cases, so no interpretation is possible from the provided data.

Answer

40 per 1,000 per week; the threshold has been dramatically exceeded and immediate lockdown is the only option.
