An epidemiologist has been studying a recent outbreak of polar snow flu and the documented results are listed below: Jan. 10: >Incidence: 25 cases of the polar-snow flu > Outbreak appears to be centered around a small town in Michigan as all patients are from said town > Signs/symptoms are similar to those of influenza but cannot identify virus in body fuid samples Jan. 20: >All patients initially were from one town but now neighboring towns are being affected >Doctor, that has been treating polar-snow flu, is now ill > Doctor's family also ill along with neighbors and grocery store clerk, all whom have not been in contact with the initial 25 patients >Signs/symptoms of initial patients improving >Incidence: 20 additional cases Jan. 30: >Initial 25 cases: patients no longer experiencing signs/symptoms > 20 cases diagnosed on Jan. 20 seeing improvement in health >No new cases identified over past 10 days. Question: Based on the information/notes provided by the epidemiologist, what is the prevalence of the disease at the end of January? Total identified cases would be 45 which would also be the prevalence. Prevalence is a cumulative number and therefore the initial 25 plus the additional 20 would If the incidence is 25 and 20 respectively than the prevalence is the average of these two numbers and would be 22.5 average cases. Prevalence is the difference between the two incidence numbers therefore 5. This information cannot be gathered from the above data​
