Need to compare incidence between two groups.

So, I have this big table. I am only interested in looking at incidence of infection (number of infections / total days of admission per age group ) and determining if there was a difference between the pre and post intervention group. What analysis should I be using.

The second table attached is the simplified version: (Total number of infections, total admissions days and Incidence of infection per 100 days of admission) distributed per age group.

Any suggestion/ help is much appreciated.

Admission daysAge groupnumber of infectionsIntervention group
