Confidence Interval for invassiveness index (Case carrier ratio)

[Fredrick orwa]

Dear colleagues I have incidence of invasive pneumococcal disease (IPD incidence) as 26.2 and Carriage prevalence of pneumococcal pneumonia as 28.3.I want to calculate case carrier ratio (CCR) which is always given as:
CCR=IPD incidence/Carriage prevalence. This is direct as it is just division.However how do I calculate confidence interval for this calculated CCR in stata?
Regards,

I have realised I can use metaprop.But just wondering if the calculation for the confidence interval is correct since metaprop require (n/N) but in this case my n and N are proportions already. Also which type of confidence interval does metaprop calculate.

I suppose calculating the CI using bootstrapping seem to be another way?
