A population of 1,000 healthy, at risk people is monitored for one year starting on January 1st, and the development of cases of

masha68 [24]

Answer:

$\mathbf{cummulative \ incidence = \dfrac{60}{1000}}$

Explanation:

We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.

Mathematically:

$\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number \ of \ population \ at \ risk \ at \ onset}}$

Given that:

Number of the population at risk = 1000 individuals

New cases during Jan 1 - Dec 31 = 60 because;

At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:

∴

$\mathbf{cummulative \ incidence = \dfrac{60}{1000}}$
