A difference between pregnant and nonpregnant women is that the prevalence of asymptomatic bacteriuria in pregnant women is 2.5-11%, as opposed to 3-8% in nonpregnant women. In as many as 40% of these cases, bacteriuria may progress to symptomatic upper UTI or pyelonephritis; this rate is significantly higher than that seen in nonpregnant women. [6]
