Show Chlamydia (Cases in 1998 in Utah = 2,209) Chlamydia infection is the most common of all bacterial sexually transmitted diseases. From 1988 through 1991 the Utah:U.S. ratio showed a Utah rate approximately one-third of the national rate. However, in 1992 the Utah rate increased to about one-half of the U.S. rate. This ratio has stayed approximately the same for the past few years, possibly reflecting increased efforts in sexually transmitted disease screening, reporting, and recognition of asymptomatic infection. Women have a higher reported incidence than do men. This may represent poor reporting of infected males and increased screening of females. The Utah:U.S. ratio for females is slightly less than half of the national figure. The male Utah:U.S. ratio is generally higher, although in 1995,1996, and 1997, the Utah rate for men dropped to nearly half the national rate. Table 67. Chlamydia" Year Utah U .S.
