Sexual Exposures Associated With Mpox Infection: California, November 2022 to June 2023.

Background: Exposures associated with mpox infection remain imperfectly understood.

Methods: We conducted a case-control study enrolling participants who received molecular tests for mpox/orthopoxvirus in California from November 2022 through June 2023. We collected data on behaviors during a 21-day risk period before symptom onset or testing among mpox case patients and test-negative controls.

Comparing 7-Day Versus 6-8-Day Penicillin Treatment Intervals Among Pregnant People With Syphilis of Late or Unknown Duration: No Difference Found in Incidence of Congenital Syphilis.

Background: Guidelines recommend that pregnant patients with syphilis of late/unknown duration be treated with benzathine penicillin G, dosed as 3 weekly intramuscular injections (BPGx3) given ideally at strict 7-day intervals. Given limited pharmacokinetic data, it is unknown whether more flexible BPG treatment intervals might be effective in preventing congenital syphilis (CS).

Methods: We used California surveillance data to identify birthing parent/infant dyads wherein the pregnant parent had syphilis of late/unknown duration between January 1, 2016 - June 30, 2019.

Characterizing the Rise of Disseminated Gonococcal Infections in California, July 2020-July 2021.

Background: California has experienced an increase in reported cases of disseminated gonococcal infection (DGI). Given significant morbidity associated with DGI and the ability of Neisseria gonorrhoeae to rapidly develop antibiotic resistance, characterization of these cases can inform diagnosis, management, and prevention of DGI.

Methods: As part of the public health response to increased reports of DGI, we used gonorrhea surveillance data reported to the California Department of Public Health to identify all DGI cases in a geographically-bound region.

Congenital syphilis prevention in the context of methamphetamine use and homelessness.

Background And Objectives: Congenital syphilis (CS) is increasing in the United States and is associated with intersecting social and structural determinants of health. This study aimed to delineate birthing parent characteristics associated with CS in an adjusted model. METHODS (N = 720): People diagnosed with syphilis during pregnancy from 2017 to 2018 who were interviewed and linked to infants in the California state surveillance system were included (herein, "birthing parents").

Neurosyphilis Surveillance: Exploring the Use of Multiple Data Sources to Better Understand Morbidity in California.

Accurate reporting of neurosyphilis diagnoses is important to quantify and monitor severe outcomes associated with infection of Treponemal pallidum. This analysis compared the demographic distribution of neurosyphilis diagnoses in sexually transmitted disease surveillance data with administrative hospital data in the California Project Area from 2016 to 2018. Although neurosyphilis morbidity was similar, significant differences were noted by sex, age group, race/ethnicity, and region.

Measuring the Impact of the COVID-19 Pandemic on Sexually Transmitted Diseases Public Health Surveillance and Program Operations in the State of California.

Background: As public health personnel and resources are redirected to COVID-19, sexually transmitted diseases (STD) programs have been unable to sustain pre-COVID-19 activities.

Methods: We used California (CA) surveillance data to describe trends in case reporting for gonorrhea, chlamydia, and syphilis of any stage in the pre- versus post-COVID-19 eras (January-June 2019 and January-June 2020). We also analyzed data from an electronic survey administered by the CA STD Control Branch to local health jurisdictions in April, June, and September of 2020, assessing the impact of COVID-19 on STD programs.

Routine Screening in a California Jail : Effect of Local Policy on Identification of Syphilis in a High-Incidence Area, 2016-2017.

Objectives: California is experiencing a syphilis and congenital syphilis epidemic, and many persons diagnosed with syphilis report a history of recent incarceration or sexual contact with a person who has recently been incarcerated. Fresno County's local health department and jail collaborated to implement a routine syphilis screening policy for male adults aged 18-30 and female adults aged 18-35 booked into the facility. We evaluated syphilis screening, case finding, and treatment rates after implementation of the new policy.

Trends in Chlamydia Screening, Test Positivity, and Treatment Among Females in California Juvenile Detention Facilities, 2003-2014.

Background: Juvenile detention facilities house adolescents at high risk for sexually transmitted diseases. Collaboration between health departments and juvenile detention authorities can provide routine, cost-efficient chlamydia screening and treatment to females with limited access to care. We describe trends in screening, positivity, treatment, and associated costs in a well-established juvenile detention chlamydia screening program.
