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. We examined epidemiologic characteristics and reported temporal trends of Shigella cases by sex and species. RESULTS: From 2007 to 2016, 10,430 shigellosis cases were reported. The annual number of reported shigellosis cases across jurisdictions increased 70%, from 821 cases in 2007 to 1398 cases in 2016; males saw a larger increase compared with females. Twenty percent of male shigellosis case-patients had an STI reported in the reference period versus 4% of female case-patients. The percentage of male shigellosis case-patients with an STI increased from 11% (2007) to 28% (2016); the overall percentage among females remained low. CONCLUSIONS: We highlight the substantial proportion of males with shigellosis who were diagnosed with STIs within 24 months and the benefit of matching data across programs. Sexually transmitted infection screening may be warranted for male shigellosis case-patients.

Inadequate Engagement in HIV Care Among People With HIV Newly Diagnosed With a Sexually Transmitted Disease: A Multijurisdictional Analysis.

BACKGROUND: A key challenge of HIV surveillance-based HIV care reengagement is locating people living with HIV (PLWH) who seem to be out of care to reengage them in care. Providing reengagement services to PLWH diagnosed with a sexually transmitted disease (STD)-individuals who are in jurisdiction and connected to the health care system-could be an efficient means of promoting HIV treatment and reducing HIV transmission. METHODS: Early and late syphilis (ES/LS) and gonorrhea (GC) cases diagnosed in 2016 and 2017 in Louisiana, Michigan, Mississippi, Oregon, Rhode Island, and Texas were matched to each state's HIV surveillance data to determine the proportion of PLWH with these infections who (1) did not have evidence of a CD4 count or viral load in the prior ≥13 months (out of care) or (2) had a viral load ≥1500 copies/mL on their most recent HIV RNA test before STD diagnosis (viremic). RESULTS: Previously diagnosed HIV infection was common among persons diagnosed with ES (n = 6942; 39%), LS (n = 4329; 27%), and GC (n = 9509; 6%). Among these ES, LS, and GC cases, 26% (n = 1543), 33% (n = 1113), and 29% (n = 2391) were out of HIV medical care or viremic at the time of STD diagnosis. CONCLUSIONS: A large proportion of STD cases with prior HIV diagnosis are out of care or viremic. Integrating relinkage to care activities into STD partner services and/or the use of matching STD and HIV data systems to prioritize data to care activities could be an efficient means for relinking patients to care and promoting viral suppression.

Brief Report: Ryan White Participation Increased the Prevalence of COVID-19 Vaccination Among People Living with HIV in Michigan.

INTRODUCTION: People living with HIV (PLWH) have higher prevalence of adverse COVID-19 outcomes, and many reside in socially vulnerable communities. Our aim was to evaluate how engagement in HIV care may increase vaccination likelihood. METHODS: Michigan HIV surveillance data were extracted from the Enhanced HIV/AIDS Reporting System and matched at the person-level to COVID-19 vaccination records from the Michigan Care Improvement Registry (through December 31, 2021 [n = 15,537]). Based on residential census tract, we classified PLWH into quartiles (<25th percentile [least vulnerable], 25th to <50th, 50th to <75th, ≥75th [most vulnerable]) of the 2018 CDC Social Vulnerability Index. Using log binomial regression, we estimated the relative prevalence of COVID-19 vaccine series initiation among PLWH by quartile of social vulnerability and Ryan White participation; models were adjusted for covariates. RESULTS: By December 31, 2021, 67% of PLWH in Michigan had initiated a COVID-19 vaccine series; 47% resided in an area deemed most vulnerable and 54% had participated in Ryan White services. Compared with PLWH in the most vulnerable quartile, those who resided in least vulnerable quartiles had higher prevalence of vaccine initiation (Prevalence Ratio [95% Confidence Interval]: 1.67 [1.50 to 1.86]). Participants in Ryan White had greater prevalence of initiation (1.52 [1.42 to 1.62]) compared with those who were not participants; initiation remained higher when adjusted for covariates including social vulnerability quartile. CONCLUSIONS: Ryan White participation was associated with increased COVID-19 vaccine initiation regardless of community-level vulnerability. Wraparound services may be key in vaccine promotion interventions in this vulnerable population.
