**4.1 Age and gender**

The combination of age more than 65 and female gender is a significant risk factor for the development of urosepsis. Bacteriuria is frequent in elderly population; more than 50% of geriatric females will have bacteriuria. A multicentre study showed that patients older than 65 years of age admitted with febrile UTIs were nearly 2.5 times more likely to develop bacteraemia than patients under the age of 65 [15].
