Impact of Age and Comorbid Conditions on Incidence Rates of COVID-19-Associated Hospitalizations, 2020-2021.

Background: COVID-19-associated hospitalization rates by age and comorbid conditions can more precisely assess risk for severe illness and target prevention and treatment strategies.

Methods: We performed a retrospective study to estimate population-based COVID-19-associated hospitalization among patients by age and selected comorbid conditions in three hospital systems in Rochester and New York City (NYC), NY. Incidence rate ratios (IRR) comparing incidence rates for patients with and without these comorbidities were determined.

Shigellosis Cases With Bacterial Sexually Transmitted Infections: Population-Based Data From 6 US Jurisdictions, 2007 to 2016.

Background: Shigella species, which cause acute diarrheal disease, are transmitted via fecal-oral and sexual contact. To better understand the overlapping populations affected by Shigella infections and sexually transmitted infections (STIs) in the United States, we examined the occurrence of reported STIs within 24 months among shigellosis case-patients.

Methods: Culture-confirmed Shigella cases diagnosed from 2007 to 2016 among residents of 6 US jurisdictions were matched to reports of STIs (chlamydia, gonorrhea, and all stages of syphilis) diagnosed 12 months before or after the shigellosis case.

Brief Report: Use of Remnant Specimens to Assess Use of HIV PrEP Among Populations With Risk of HIV Infection: A Novel Approach.

Background: HIV-uninfected persons being evaluated for sexually transmitted infections (STIs) may be good HIV pre-exposure prophylaxis (PrEP) candidates. We measured PrEP use in a sentinel STI patient population.

Design: Cross-sectional study, New York City Sexual Health Clinics (January 2019-June 2019).

Test of Cure Return Rate and Test Positivity, Strengthening the US Response to Resistant Gonorrhea, United States, 2018-2019.

Background: Reduced antibiotic susceptibility (RS) in Neisseria gonorrhoeae (GC) may increase treatment failure. Conducting tests of cure (TOC) for patients with RS-GC may facilitate identification of treatment failures.

Methods: We examined 2018 to 2019 data from 8 jurisdictions participating in the US Centers for Disease Control and Prevention's Strengthening US Response to Resistant Gonorrhea project.

Effectiveness of Syphilis Partner Notification After Adjusting for Treatment Dates, 7 Jurisdictions.

Background: Disease intervention specialists (DIS) prevent syphilis by ensuring treatment for patients' sex partners through partner notification (PN). Different interpretations of how to measure partners treated due to DIS efforts complicates PN evaluation. We measured PN impact by counting partners treated for syphilis after DIS interviewed the patient.

Epidemiology of Reported HIV and Other Sexually Transmitted Infections During the COVID-19 Pandemic, New York City.

Early in the coronavirus disease 2019 (COVID-19) crisis, a statewide executive order (PAUSE) severely restricted the movement of New Yorkers from 23 March to 7 June 2020. We used New York City surveillance data for human immunodeficiency virus (HIV), chlamydia, gonorrhea, and syphilis to describe trends in diagnosis and reporting surrounding PAUSE. During PAUSE, the volume of positive HIV/sexually transmitted infection tests, and diagnoses of HIV, chlamydia, gonorrhea, and syphilis declined substantially, reaching a nadir in April before rebounding.

Assessing the Burden of Infant Deaths Due to Herpes Simplex Virus, Human Immunodeficiency Virus, and Congenital Syphilis: United States, 1995 to 2017.

Background: Despite advances in diagnosis and treatment, neonatal infection with herpes simplex virus (HSV) has a high case fatality rate. The national burden of neonatal HSV and associated deaths is unknown because this condition is not nationally notifiable. We investigated trends in HSV-related infant deaths compared with infant deaths from congenital syphilis (CS) and human immunodeficiency virus (HIV).

Unnamed Partners From Syphilis Partner Services Interviews, 7 Jurisdictions.

Background: Reducing transmission depends on the percentage of infected partners treated; if many are missed, impact on transmission will be low. Traditional partner services metrics evaluate the number of partners found and treated. We estimated the proportion of partners of syphilis patients not locatable for intervention.

The Distribution and Spread of Susceptible and Resistant Neisseria gonorrhoeae Across Demographic Groups in a Major Metropolitan Center.

Background: Genomic epidemiology studies of gonorrhea in the United States have primarily focused on national surveillance for antibiotic resistance, and patterns of local transmission between demographic groups of resistant and susceptible strains are unknown.

Methods: We analyzed a convenience sample of genome sequences, antibiotic susceptibility, and patient data from 897 gonococcal isolates cultured at the New York City (NYC) Public Health Laboratory from NYC Department of Health and Mental Hygiene (DOHMH) Sexual Health Clinic (SHC) patients, primarily in 2012-2013. We reconstructed the gonococcal phylogeny, defined transmission clusters using a 10 nonrecombinant single nucleotide polymorphism threshold, tested for clustering of demographic groups, and placed NYC isolates in a global phylogenetic context.

Estimating Neonatal Herpes Simplex Virus Incidence and Mortality Using Capture-recapture, Florida.

Background: Neonatal herpes simplex virus infection (nHSV) leads to severe morbidity and mortality, but national incidence is uncertain. Florida regulations require that healthcare providers report cases, and clinical laboratories report test results when herpes simplex virus (HSV) is detected. We estimated nHSV incidence using laboratory-confirmed provider-reported cases and electronic laboratory reports (ELR) stored separately from provider-reported cases.

Do Prescriptions for Expedited Partner Therapy for Chlamydia Get Filled? Findings From a Multi-Jurisdictional Evaluation, United States, 2017-2019.

Background: Expedited partner therapy (EPT) is commonly provided by prescription; however, the efficacy of this modality is unknown. We examined whether EPT prescriptions are filled when the cost barrier is removed.

Methods: To track EPT prescription fill rates, we used single-use pharmacy vouchers that covered the cost of azithromycin, 1 g (chlamydia treatment).

Frequency and Characteristics of Biological False-Positive Test Results for Syphilis Reported in Florida and New York City, USA, 2013 to 2017.

Discordant syphilis test results, with a reactive nontreponemal test and nonreactive treponemal test are usually considered biological false-positive test results (BFPs), which can be attributed to other conditions. Syphilis surveillance laws mandate laboratory reporting of reactive syphilis tests, which include many BFPs. We describe the frequency of BFPs, titer distributions, and titer increases from reported test results in Florida and New York City (NYC).

Incidence and Characteristics of Neonatal Herpes: Comparison of Two Population-Based Data Sources, New York City, 2006-2015.

Background: Neonatal herpes (nHSV) is a potentially fatal disease caused by herpes simplex virus (HSV) infection during the neonatal period. Neonatal herpes simplex virus infections are not nationally notifiable, and varying incidence rates have been reported. Beginning in 2006, New York City (NYC) required reporting of nHSV infections and conducted case investigations.

Factors Contributing to Congenital Syphilis Cases - New York City, 2010-2016.

Congenital syphilis occurs when syphilis is transmitted from a pregnant woman to her fetus; congenital syphilis can be prevented through screening and treatment during pregnancy. Transmission to the fetus can occur at any stage of maternal infection, but is more likely during primary and secondary syphilis, with rates of transmission up to 100% at these stages (1). Untreated syphilis during pregnancy can cause spontaneous abortion, stillbirth, and early infant death.

Lymphogranuloma Venereum: An Increasingly Common Anorectal Infection Among Men Who Have Sex With Men Attending New York City Sexual Health Clinics.

Using Chlamydia trachomatis anorectal specimens routinely tested for lymphogranuloma venereum (LGV) (2008-2011) and samples of archived specimens tested for LGV (2012-2015), we observed increased LGV positivity among men who have sex with men attending NYC Sexual Health Clinics. Using clinical data, we determined predictors of anorectal LGV that may guide clinical management.

HIV Care and Viral Load Suppression After Sexual Health Clinic Visits by Out-of-Care HIV-Positive Persons.

Outcomes among people living with HIV (PLWH) in New York City (NYC) remain suboptimal. To assess the potential role of the city's sexual health clinics (SHCs) in improving HIV outcomes and reducing HIV transmission, we examined HIV care status and its correlates among HIV-positive SHC patients in NYC. Clinic electronic medical records were merged with longitudinal NYC HIV surveillance data to identify HIV-positive patients and derive their retrospective and prospective HIV care status.

Reactor Grids for Prioritizing Syphilis Investigations: Are Primary Syphilis Cases Being Missed?

Background: Health departments prioritize investigations of reported reactive serologic tests based on age, gender, and titer using reactor grids. We wondered how reactor grids are used in different programs, and if administratively closing investigations of low-titer tests could lead to missed primary syphilis cases.

Methods: We obtained a convenience sample of reactor grids from 13 health departments.

The Epidemiology of Syphilis in New York City: Historic Trends and the Current Outbreak Among Men Who Have Sex With Men, 2016.

Background: Male primary and secondary (P&S) and early latent syphilis cases have increased markedly in New York City (NYC) after a historic nadir in 1998. The majority of cases are among men who have sex with men (MSM). We describe the epidemiology of syphilis among NYC males to provide a model of how 1 jurisdiction collects, analyzes, interprets, uses, and disseminates local data to guide programmatic activities directed at syphilis control.

Frequency of Nucleic Acid Amplification Test Positivity Among Men Who Have Sex With Men Returning for a Test-of-Cure Visit 7 to 30 Days After Treatment of Laboratory-Confirmed Neisseria gonorrhoeae Infection at 2 Public Sexual Health Clinics, New York City, 2013 to 2016.

Background: The Centers for Disease Control and Prevention 2015 Sexually Transmitted Disease Treatment Guidelines recommend that clinicians consider cephalosporin treatment failure in patients who deny interval sexual exposure and are nucleic acid amplification test (NAAT) positive for Neisseria gonorrhoeae (NG) at least 7 days after adequate treatment. We evaluate the real-world implications of the interval the Centers for Disease Control and Prevention recommends for a NAAT test-of-cure (TOC), by ascertaining the frequency of NG NAAT positivity at different anatomic sites among men who have sex with men (MSM) at TOC 7 to 30 days after treatment.

Methods: We analyzed data from the medical records of MSM with laboratory-confirmed NG who were presumptively treated for NG during the period from June 2013 to April 2016 and returned for a TOC visit within 30 days.

Sentinel Surveillance for Expedited Partner Therapy Prescriptions Using Pharmacy Data, in 2 New York City Neighborhoods, 2015.

Background: Expedited partner therapy (EPT) for Chlamydia trachomatis (Ct) is the practice of providing Ct-infected patients with medication, or prescription (prescription-EPT) to deliver to their sex partners without first examining those partners. New York City (NYC) providers commonly use prescription-EPT, yet NYC pharmacists report only occasional receipt of EPT prescriptions. This project assessed the frequency of EPT prescriptions filled in 2 NYC neighborhoods.

Pharmacists' Knowledge and Practices Surrounding Expedited Partner Therapy for Chlamydia trachomatis, New York City, 2012 and 2014.

Background: Health care providers in New York City can prescribe treatment for Chlamydia trachomatis (Ct) for a patient's partner without the partner having a medical evaluation ("prescription-expedited partner therapy" [EPT]), and use of prescription-EPT is common. However, there is little known about pharmacists' knowledge and practices surrounding EPT.

Methods: Two cross-sectional surveys, in 2012 and 2014, were conducted with representative samples of supervising pharmacists in NYC neighborhoods with high rates of Ct infection.
