JACKSONVILLE, FLA. -- The reasons for prominent increases in reported gonorrhea cases since 2000 in five Western states as well as Hawaii and Alaska remain unknown, Dr. Lori M. Newman said at a conference on STD prevention sponsored by the Centers for Disease Control and Prevention.
A combination of better gonorrhea detection, increased risky sexual behavior, reduced disease control efforts, and/or increased antimicrobial resistance likely accounts for the 25% or more jump in gonorrhea cases in the "wild West," said Dr. Newman, medical officer, Division of STD Prevention at the CDC.
Among states with at least 500 gonorrhea cases reported in 2005, preliminary data indicate that the greatest increases since 2000 were seen in Utah (206% increase), Hawaii (107%), California (55%), Washington (53%), Oregon (50%), Alaska (48%), and Nevada (40%).
In contrast to national trends, aggregated data for these seven states indicate a 48% increase in new cases among males and a 40% increase in new cases among females between 2000 and 2005. This disparity parity suggests increases among men who have sex with men, Dr. Newman said. However, overall increases suggest heterosexual transmission as well.
The overall gender gap for gonorrhea has narrowed. Historically, males have had higher infection rates, but female transmission surpassed that of males slightly during the last 3 reported years. The 2004 transmission rates were 117 females per 100,000 and 110 males per 100,000 in the United States.
CDC researchers have yet to identify any demographic risk factor that might explain the increases in the seven states. The increases are ...
