Urinary tract infections are found more frequently in women than in men. It is estimated that more than 30% of women will experience at least one episode of cystitis. Of these 30%, 20% women will have recurrent cystitis. The case-fatality rate/mortality rate of uncomplicated cystitis is approximately zero. Females are more commonly affected with cystitis than males. The female to male ratio is 4 to 1. Acute uncomplicated cystitis commonly affects women ages 18-39 years. There is no racial predilection to cystitis. Cystitis is a common disease that affect everyone, mostly women, worldwide.
- It is estimated that one third of the women population has at least one episode of cystitis in their lifetime. Of these many will have recurrent cystitis.
- 81% of the total UTIs in the world occur in women.
- 27% of women with an episode of UTI have another episode within the next 6 months while 48% within the next 12 months.
- More than 7 million uncomplicated UTIs occur in the US per year.
- Sexually active women are known to have a higher incidence of UTIs than women of other categories.
- The incidence of cystitis in women is 5-7 per year per 100,000 while that in same age men is 50-80 per 100000.
- The incidence of UTI is higher in sexually active women than postmenopausal women.
- There is a higher incidence of urinary tract infection in immunocompromised, elderly, diabetic, and individuals with indwelling catheters.
- Almost 30% of the women will experience at least one episode of cystitis during their life span. Of these 30%, 20% of these women will have recurrent cystitis.
Case-fatality rate/Mortality rate
- The case-fatality rate/mortality rate of uncomplicated cystitis is approximately zero.
- Acute uncomplicated cystitis commonly affects women ages 18-39 years.
- UTIs are less frequent in 2-13 years old girls.
- Urinary tract infections can rarely occur in boys in the first year after birth in the presence of a structural defect or due to lack of circumcision.
- There is no racial predilection to cystitis.
- Females are more commonly affected with cystitis than males. The female to male ratio is 4 to 1.
- Cystitis is a common disease that affect everyone, mostly women, worldwide.
