Past-Year HIV Testing, Current Antiretroviral Therapy Use, and Participation in Services for People Who Inject Drugs.

Evaluating routine HIV testing and treatment and use of services for people who inject drugs (PWID) is critical to curb the ongoing HIV epidemic. We analyzed data from the 2018 National HIV Behavioral Surveillance of PWID aged 18 years or older, recruited using respondent-driven sampling and offered anonymous HIV testing after survey. We performed bivariate and multivariable analyses with log-linked Poisson regression of the generalized linear models to examine the associations between demographics and PWID service use, past-year HIV testing, and current antiretroviral therapy (ART) use. Among 10,311 HIV-negative PWID, 56% reported past-year HIV testing, and of the 553 HIV-positive PWID, 69% reported current ART use. Of the HIV-negative PWID, 64% (2874/4482) in drug treatment and 62% (3386/5440) who used syringe service programs (SSPs) reported past-year HIV testing. Among HIV-positive PWID, 75% (187/248) in drug treatment and 67% (200/298) SSP participants were on ART. In the adjusted multivariable model, past-year HIV testing was associated with drug use treatment (aPR 1.26, 95% CI 1.23-1.31) and SSP participation (aPR 1.19, 95% CI 1.13-1.26) among HIV-negative PWID. Current ART use was associated with drug use treatment (aPR 1.13, 95% CI 1.00-1.28) but the link was not significant probably due to small sample size. Findings support the expansion and improvement of PWID-targeted services, into comprehensive programs, including drug use treatment, SSP, and HIV testing and treatment.

A Comprehensive Program to Improve Treatment of Precancerous Cervical Lesions in the Rio Grande Valley of Texas.

OBJECTIVE: To assess the impact of a multicomponent intervention in women with cervical dysplasia who were treated with loop electrosurgical excision procedure (LEEP), as well as the time between colposcopy and treatment. DESIGN: Retrospective cohort study. INTERVENTION: Clinic participation in a multicomponent cervical cancer prevention program that included community outreach, patient in-reach, and navigation, as well as provider capacity building with in-person training and ongoing telementoring through Project ECHO. MAIN OUTCOME MEASURES: Medical records were reviewed to evaluate women with cervical dysplasia undergoing treatment with LEEP within 90 days of colposcopy, as well as time between colposcopy and treatment. Baseline data from year 1 were compared with each subsequent year of implementation. Additional variables examined included patient's age, history of abnormal screening results, and percentage of families living below poverty line based on county of residence, parity, and clinic site. We performed logistic regression and multiple linear regression analyses to assess the programmatic impact in the outcomes of interest by year of program implementation. RESULTS: A total of 290 women were included in the study. The proportion of women undergoing treatment within 90 days of colposcopy increased from 76.2% at baseline to 91.3% in year 3 and 92.9% in year 4 of program implementation. The odds of undergoing treatment within 90 days were 5.11 times higher in year 4 of program implementation than at baseline. The mean time between colposcopy and LEEP decreased from 62 days at baseline to 45 days by year 4 of program implementation. CONCLUSIONS: Implementation of our multicomponent cervical cancer prevention program increased the proportion of women undergoing LEEP within 90 days of colposcopy and decreased the time between colposcopy and LEEP. This program has the potential to support cervical cancer prevention efforts and could be implemented in other low-resource settings.

Analysis of the spatial and temporal distribution of malaria in an area of Northern Guatemala with seasonal malaria transmission.

The risk of malaria infection displays spatial and temporal variability that is likely due to interaction between the physical environment and the human population. In this study, we performed a spatial analysis at three different time points, corresponding to three cross-sectional surveys conducted as part of an insecticide-treated bed nets efficacy study, to reveal patterns of malaria incidence distribution in an area of Northern Guatemala characterized by low malaria endemicity. A thorough understanding of the spatial and temporal patterns of malaria distribution is essential for targeted malaria control programs. Two methods, the local Moran's I and the Getis-Ord G*(d), were used for the analysis, providing two different statistical approaches and allowing for a comparison of results. A distance band of 3.5 km was considered to be the most appropriate distance for the analysis of data based on epidemiological and entomological factors. Incidence rates were higher at the first cross-sectional survey conducted prior to the intervention compared to the following two surveys. Clusters or hot spots of malaria incidence exhibited high spatial and temporal variations. Findings from the two statistics were similar, though the G*(d) detected cold spots using a higher distance band (5.5 km). The high spatial and temporal variability in the distribution of clusters of high malaria incidence seems to be consistent with an area of unstable malaria transmission. In such a context, a strong surveillance system and the use of spatial analysis may be crucial for targeted malaria control activities.

Depression and HIV risk among men who have sex with men in Tanzania.

Studies have shown high rates of depression among men who have sex with men (MSM) in developed countries. Studies have also shown association between depression and HIV risk among MSM. However, very little research has been done on depression among African MSM. We assessed depression and HIV risk among a sample of MSM in Tanzania. We reviewed data on 205 MSM who were recruited from two Tanzanian cities using the respondent driven sampling method. Demographic and behavioral data were collected using a structured questionnaire. HIV and sexually transmitted infections data were determined from biological tests. Depression scores were assessed using the Patient Health Questionnaire (PHQ-9). For the analysis, depression scores were dichotomized as depressed (PHQ > 4) and not depressed (PHQ ≤ 4). Bivariate and multivariable Poisson regression analyses were conducted to assess factors associated with depression. The prevalence of depression in the sample was 46.3%. The mean (±SD) age of the sample was 25 (±5) years. In bivariate analysis, depression was associated with self-identifying as gay (p = .001), being HIV positive (p < .001: <8% of MSM knew they were HIV infected) and having a high number of sexual partners in the last 6 months (p = .001). Depression was also associated with sexual (p = .007), physical (p = .003) and verbal (p < .001) abuse. In the Poisson regression analysis, depression was associated with verbal abuse (APR = 1.91, CI = 1.30-2.81). Depression rates were high among MSM in Tanzania. It is also associated with abuse, HIV and HIV risk behaviors. Thus, reducing the risk of depression may be helpful in reducing the risk of HIV among MSM in Africa. We recommend the colocation of mental health and HIV preventive services as a cost-effective means of addressing both depression and HIV risk among MSM in Africa.

Interventions to increase follow-up of abnormal cervical cancer screening results: A systematic literature review and meta-analysis.

INTRODUCTION: Ensuring timely follow-up of abnormal screening results is essential for eliminating cervical cancer. OBJECTIVE: The purpose of the study was to review single and multicomponent interventions designed to improve follow-up of women with abnormal cervical cancer screening results. We report on effectiveness across studies, and describe what aspects of these interventions might be more impactful. METHODS: Publications were searched between January 2000 and December 2022. The search included observational, quasi-experimental (pre-post studies) and randomized controlled studies describing at least one intervention to increase follow-up of women with abnormal cervical cancer screening results. Outcomes of studies included completion of any follow-up (i.e., attending a follow-up appointment), timely diagnosis (i.e., colposcopy results within 90 days of screening) and time to diagnostic resolution (i.e., days between screening and final diagnosis). We assessed risk of bias for observational and quasi-experimental studies using the Newcastle-Ottawa Scale (NOS) tool and the Cochrane collaboration tool for randomized studies. We conducted a meta-analysis using studies where data were provided to estimate a summary average effect of the interventions on follow-up of patients and to identify characteristics of studies associated with an increased effectiveness of interventions. We extracted the comparison and intervention proportions of women with follow-up before and after the intervention (control and intervention) and plotted the odds ratios (ORs) of completing follow-up along with the 95% confidence intervals (CIs) using forest plots for the interventions vs. controls when data were available. FINDINGS: From 7,457 identified studies, 28 met the inclusion criteria. Eleven (39%) of the included studies had used a randomized design. Most studies (63%) assessed completion of any follow-up visit as the primary outcome, whereas others measured time to definite diagnosis (15%) or diagnostic resolution (22%). Navigation was used as a type of intervention in 63% of the included studies. Most interventions utilized behavioral approaches to improve outcomes. The overall estimate of the OR for completion of follow-up for all interventions was 1.81 (1.36-2.42). The highest impact was for programs using more than one approach (multicomponent interventions) to improve outcomes with OR = 3.01 (2.03-4.46), compared with studies with single intervention approaches with OR = 1.56 (1.14-2.14). No statistical risks were noted from publication bias or small-study effects in the studies reviewed. CONCLUSION: Our findings revealed large heterogeneity in how follow-up of abnormal cervical cancer screening results was defined. Our results suggest that multicomponent interventions were more effective than single component interventions and should be used to improve follow-up after abnormal cervical cancer screening results. Navigation appears to be an important tool for improving follow-up. We also provide recommendations for future studies and implications for policy in terms of better defining outcomes for these interventions.

Revealing patterns of SARS-CoV-2 variant emergence and evolution using RBD amplicon sequencing of wastewater.

OBJECTIVES: Rapid evolution of SARS-CoV-2 has resulted in the emergence of numerous variants, posing significant challenges to public health surveillance. Clinical genome sequencing, while valuable, has limitations in capturing the full epidemiological dynamics of circulating variants in the general population. This study aimed to monitor the SARS-CoV-2 variant community dynamics and evolution using receptor-binding domain (RBD) amplicon sequencing of wastewater samples. METHODS: We sequenced wastewater from El Paso, Texas, over 17 months, compared the sequencing data with clinical genome data, and performed biodiversity analysis to reveal SARS-CoV-2 variant dynamics and evolution. RESULTS: We identified 91 variants and observed waves of dominant variants transitioning from BA.2 to BA.2.12.1, BA.4&5, BQ.1, and XBB.1.5. Comparison with clinical genome sequencing data revealed earlier detection of variants and identification of unreported outbreaks. Our results also showed strong consistency with clinical data for dominant variants at the local, state, and national levels. Alpha diversity analyses revealed significant seasonal variations, with the highest diversity observed in winter. By segmenting the outbreak into lag, growth, stationary, and decline phases, we found higher variant diversity during the lag phase, likely due to lower inter-variant competition preceding outbreak growth. CONCLUSIONS: Our findings underscore the importance of low transmission periods in facilitating rapid mutation and variant evolution. Our approach, integrating RBD amplicon sequencing with wastewater surveillance, demonstrates effectiveness in tracking viral evolution and understanding variant emergence, thus enhancing public health preparedness.

RBD amplicon sequencing of wastewater reveals patterns of variant emergence and evolution.

Rapid evolution of SARS-CoV-2 has resulted in the emergence of numerous variants, posing significant challenges to public health surveillance. Clinical genome sequencing, while valuable, has limitations in capturing the full epidemiological dynamics of circulating variants in the general population. This study utilized receptor-binding domain (RBD) amplicon sequencing of wastewater samples to monitor the SARS-CoV-2 community dynamics and evolution in El Paso, TX. Over 17 months, we identified 91 variants and observed waves of dominant variants transitioning from BA.2 to BA.2.12.1, BA.4&5, BQ.1, and XBB.1.5. Our findings demonstrated early detection of variants and identification of unreported outbreaks, while showing strong consistency with clinical genome sequencing data at the local, state, and national levels. Alpha diversity analyses revealed significant periodical variations, with the highest diversity observed in winter and the outbreak lag phases, likely due to lower competition among variants before the outbreak growth phase. The data underscores the importance of low transmission periods for rapid mutation and variant evolution. This study highlights the effectiveness of integrating RBD amplicon sequencing with wastewater surveillance in tracking viral evolution, understanding variant emergence, and enhancing public health preparedness.

Wastewater pandemic preparedness: Toward an end-to-end pathogen monitoring program.

Molecular analysis of public wastewater has great potential as a harbinger for community health and health threats. Long-used to monitor the presence of enteric viruses, in particular polio, recent successes of wastewater as a reliable lead indicator for trends in SARS-CoV-2 levels and hospital admissions has generated optimism and emerging evidence that similar science can be applied to other pathogens of pandemic potential (PPPs), especially respiratory viruses and their variants of concern (VOC). However, there are substantial challenges associated with implementation of this ideal, namely that multiple and distinct fields of inquiry must be bridged and coordinated. These include engineering, molecular sciences, temporal-geospatial analytics, epidemiology and medical, and governmental and public health messaging, all of which present their own caveats. Here, we outline a framework for an integrated, state-wide, end-to-end human pathogen monitoring program using wastewater to track viral PPPs.

Wastewater sequencing reveals community and variant dynamics of the collective human virome.

Wastewater is a discarded human by-product, but its analysis may help us understand the health of populations. Epidemiologists first analyzed wastewater to track outbreaks of poliovirus decades ago, but so-called wastewater-based epidemiology was reinvigorated to monitor SARS-CoV-2 levels while bypassing the difficulties and pit falls of individual testing. Current approaches overlook the activity of most human viruses and preclude a deeper understanding of human virome community dynamics. Here, we conduct a comprehensive sequencing-based analysis of 363 longitudinal wastewater samples from ten distinct sites in two major cities. Critical to detection is the use of a viral probe capture set targeting thousands of viral species or variants. Over 450 distinct pathogenic viruses from 28 viral families are observed, most of which have never been detected in such samples. Sequencing reads of established pathogens and emerging viruses correlate to clinical data sets of SARS-CoV-2, influenza virus, and monkeypox viruses, outlining the public health utility of this approach. Viral communities are tightly organized by space and time. Finally, the most abundant human viruses yield sequence variant information consistent with regional spread and evolution. We reveal the viral landscape of human wastewater and its potential to improve our understanding of outbreaks, transmission, and its effects on overall population health.

Accelerated hepatitis B vaccination schedule among drug users: a randomized controlled trial.

BACKGROUND: Hepatitis B vaccine provides a model for improving uptake and completion of multidose vaccinations in the drug-using community. METHODS: The Drugs, AIDS, STDs, and Hepatitis (DASH) project conducted a randomized controlled trial among not-in-treatment current drug users in 2 urban neighborhoods. Neighborhoods were cluster-randomized to receive a standard behavioral intervention (which provided information on human immunodeficiency virus [HIV]) or an enhanced behavioral intervention (designed to increase acceptance of or adherence to the hepatitis B vaccination protocol). Participants within clusters were randomized to a standard vaccination schedule (vaccines at 0, 1, and 6 months) or an accelerated vaccination schedule (vaccines at 0, 1, and 2 months). The outcomes were completion of the 3-dose vaccine and seroprotection against hepatitis B virus (HBV). RESULTS: Of participants with negative screening results for HIV and HBV, 77% accepted hepatitis B vaccination, and 75% of vaccinees received all 3 doses. Injection drug users (IDUs) on the accelerated schedule were significantly more likely to receive 3 doses (76%) than those on the standard schedule (66%; P = .04), although for drug users as a whole the corresponding adherence rates were 77% and 73%, respectively. No difference in adherence was observed between the behavioral intervention groups. Predictors of adherence were older age, African American race, stable housing, and alcohol use. Cumulative HBV seroprotection (≥10 mIU/mL) was gained within 12 months by 65% of those completing the schedule. Seroprotection at 6 months was greater for those on the accelerated schedule. CONCLUSION: The accelerated vaccination schedule improves hepatitis B vaccination adherence among IDUs.

Juvenile Justice-Involved Youth: Preventive Health Services Received Prior to Detention.

Few studies on youth in the juvenile justice system describe preventive services received at community health visits. We determined preventive services received at their most recent visit to a health care provider through a cross-sectional survey of youth at a detention center. Data on their health outcomes were abstracted from medical records. Many did not receive comprehensive screenings for sexual health, mental health symptoms, or substance use at well-child visits in the past year. Health outcomes were not significantly different from those who did not attend a well visit in the past year. Limited preventive screenings could explain why well checks did not influence health outcomes; therefore, providers should incorporate recommended screenings into sick visits as well as preventive visits.

The Epidemiology of Meningitis in Infants under 90 Days of Age in a Large Pediatric Hospital.

BACKGROUND: Meningitis is associated with substantial morbidity and mortality, particularly in the first three months of life. METHODS: We conducted a retrospective review of patients <90 days of age with meningitis at Texas Children's Hospital from 2010-2017. Cases were confirmed using the National Healthcare Safety Network (NHSN) definition of meningitis. RESULTS: Among 694 infants with meningitis, the most common etiology was viral (n = 351; 51%), primarily caused by enterovirus (n = 332; 95%). A quarter of cases were caused by bacterial infections (n = 190; 27%). The most common cause of bacterial meningitis was group B Streptococcus (GBS, n = 60; 32%), followed by Gram-negative rods other than E. coli (n = 40; 21%), and E. coli (n = 37; 19%). The majority of Gram-negative organisms (63%) were resistant to ampicillin, and nearly one-fourth of Gram-negative rods (23%) other than E. coli and 2 (6%) E. coli isolates were resistant to third-generation cephalosporins. Significant risk factors for bacterial meningitis were early preterm birth and the Black race. CONCLUSIONS: Enteroviruses most commonly caused viral meningitis in infants; GBS was the most common bacterial cause despite universal screening and intrapartum prophylaxis. The emergence of MRSA and resistance to third-generation cephalosporins in Gram-negative bacterial meningitis challenges the options for empirical antimicrobial therapy.

Caregiver and Pediatric Health Care Provider Views on Social Needs Identification.

Background: The American Academy of Pediatrics recommends that pediatricians address the social determinants of health (SDOH) through research, community partnership, and policy development. Objective: This study aimed to identify the unmet SDOH of the patients served by the Pasadena-Pediatric and Adolescent Health Center (PA-PAHC) and to understand provider perspectives on screening for SDOH. Methods: The PA-PAHC is a low-income pediatric clinic in southeast Houston. A cross-sectional survey eliciting potential SDOH concerns was administered to caregivers of children presenting for their well-child exam, along with pediatric residents and staff/faculty. Staff/faculty and residents were asked about their perceptions of SDOH screening. Statistical analysis calculated frequencies for categorical data and mean/median for continuous variables. Secondary data analysis consisted of chi-square test and logistic regression. Results: A total of 110 caregivers, 22 residents, and 21 staff/faculty participated in the study. Caregivers listed health care access the most frequently (15.5%), followed by childcare, school, and immigration status as SDOH concerns. Residents (31.8%) and staff/faculty (23.8%) also identified health care access as a concern. When comparing topic selection by survey role, there was no statistically significant difference among the 3 groups (P = .257). Residents were more likely to indicate that screening was more time-consuming than were faculty/staff (P = .004). Conclusion: Staff/faculty and residents agree that SDOH affect child health and screening is valuable in the patient encounter. There were no differences in the needs identified by the 3 groups. Further evaluation to assess caregiver perspectives on standardized SDOH screening versus obtaining routine social history needs to be undertaken.

Low Yield of Hepatitis C Infection in an Outreach Screening Program in Harris County, Texas.

A community outreach hepatitis C virus (HCV) infection screening program provided low yield of detecting HCV-infected patients, linking them to our hepatology clinic for treatment. Our data underscore that most of the yield was related to addiction centers and birth cohort; these groups should be targeted by future interventions.

Factors associated with knowledge of where to access health care among youth in juvenile detention: a mixed methods study.

BACKGROUND: Mental illness, substance use, and sexual health issues are major health concerns among detained youth compared with the general population. There is a dearth of studies that demonstrate what detained youth in the United States know about where to access health services in the community. Given the magnitude of these health concerns among detained youth compared with youth in the general population, knowing where to access health care in the community could lead to early intervention and better health outcomes. OBJECTIVES: This study determines what detained youth know about where to access care for mental health symptoms, substance use, and sexually transmitted infections, and identifies the factors associated with knowledge of where to access health care. METHODS: Data were collected using mixed methods from a cross-sectional sample of 301 detained youth. Information was obtained using surveys (which included closed and open-ended questions), and data abstraction from their medical records. Logistic regression analysis, Chi-squared tests and thematic analysis were used to analyze the data. Results Having a primary care provider, perceived susceptibility, and previous experiences with health care providers all influenced what youth in our study knew about where to seek health care. CONCLUSIONS: The use of mixed methods including open-ended questions allowed us to gain a better perspective of where detained youth would seek help for health issues. Detained youth have poorer health outcomes yet many did not know where to access health resources. Primary care providers who see youth should provide comprehensive, youth-friendly services.

Does Juvenile Detention Impact Health?

Youth involved in the juvenile justice system represent a medically underserved population. Recidivist youth have poorer health outcomes compared to youth detained for the first time. This study determined differences in immunization history, substance use, mental health symptoms, and sexual behavior between recidivist youth and first-time detainees following improvements in intake screenings at a large, urban juvenile detention center in the Southeastern United States. Multivariable logistic regression analysis found that recidivist youth had significantly higher acellular pertussis immunization rates compared with first-time detainees (odds ratio [ OR] = 3.3; p = .02), and recidivist males were less likely to test positive for chlamydia ( OR = 0.6; p = .03) after controlling for age and Black race. There was no significant difference for most other outcomes between recidivist youth and first-time detainees after controlling for age.

Enhanced Methodologies to Enumerate Persons Experiencing Homelessness in a Large Urban Area.

INTRODUCTION: Homelessness is a public health problem, and persons experiencing homelessness are a vulnerable population. Estimates of the number of persons experiencing homelessness inform funding allocations and services planning and directly determine the ability of a community to intervene effectively in homelessness. The point-in-time (PIT) count presents a logistical problem in large urban areas, particularly those covering a vast geographical area. MATERIALS AND METHODS: Working together, academia, local government, and community organizations improved the methodology for the count. Specific enhancements include use of incident command system (ICS), increased number of staging areas/teams, specialized outreach and Special Weapons and Tactics teams, and day-after surveying to collect demographic information. RESULTS: This collaboration and enhanced methodology resulted in a more accurate estimate of the number of persons experiencing homelessness and allowed comparison of findings for 4 years. While initial results showed an increase due to improved counting, the number of persons experiencing homelessness counted for the subsequent years showed significant decrease during the same time period as a "housing first" campaign was implemented. The collaboration also built capacity in each sector: The health department used ICS as a training opportunity; the academics enhanced their community health efforts; the service sector was taught and implemented more rigorous quantitative methods; and the community was exposed to public health as a pragmatic and effective discipline. PRACTICAL IMPLICATIONS: Improvements made to increase the reliability of the PIT count can be adapted for use in other jurisdictions, leading to improved counts and better evaluation of progress in ending homelessness.

Effect of age and frequency of injections on immune response to hepatitis B vaccination in drug users.

Despite the high immunogenicity of the hepatitis B vaccine, evidence suggests that immunological response in drug users is impaired compared to the general population. A sample of not-in-treatment adult drug users from two communities in Houston, TX, USA, susceptible to hepatitis B virus (HBV), was sampled via outreach workers and referral methodology. Participants were randomized to either the standard multi-dose hepatitis B vaccine schedule (0, 1, and 6 months) or to an accelerated (0, 1, and 2 months) schedule. The participants were followed for 1 year. Antibody levels were measured at 2, 6 and 12 months after enrollment in order to determine the immune responses. At 12 months, cumulative adequate protective response was achieved in 65% of the HBV susceptible subgroup using both the standard and accelerated schedules. The standard group had a higher mean antibody titer (184.6 mIU/mL vs 57.6 mIU/mL). But at 6 months, seroconversion at the adequate protective response was reached by a higher proportion of participants and the mean antibody titer was also higher in the accelerated schedule group (104.8 mIU/mL vs. 64.3 mIU/mL). Multivariate analyses indicated a 63% increased risk of non-response for participants 40 years or older (p=0.046). Injecting drugs more than once a day was also highly associated with the risk of non-response (p=0.016). Conclusions from this research will guide the development of future vaccination programs that anticipate other prevalent chronic conditions, susceptibilities, and risk-taking behaviors of hard-to-reach populations.

Relationship of cosmetic procedures and drug use to hepatitis C and hepatitis B virus infections in a low-risk population.

We conducted an anonymous cross-sectional seroprevalence study of a population with a low frequency of injection drug use to determine whether persons with a history of cosmetic procedures, such as tattooing and body piercing, or intranasal drug use were at increased risk for hepatitis C virus (HCV) or hepatitis B virus (HBV) infection. Students 18 years and older from eight college campuses in Houston, Texas, were invited to participate in the study. Of the 7,960 who completed a self-administered questionnaire and provided a blood sample, 5,282 U.S.- or Canadian-born participants were analyzed. Their median age was 21, 62% were female, 42% were white, 26% black, 22% Hispanic, and 10% Asian or other. Two percent reported injection drug use, 13.7% intranasal drug use, 21.2% body piercings, and 25.2% tattoos. The overall prevalence of HCV infection was 0.9% and of HBV infection was 5.2%. Higher HCV prevalence was independently associated with increasing age (odds ratio [OR] per year = 1.11; 95% confidence interval [CI] = 1.08-1.14), history of injection drug use (OR = 18.24; 95% CI = 7.74-42.92), blood transfusion before 1991 (OR = 3.21; 95% CI = 1.02-10.12), and incarceration (OR = 3.48; 95% CI = 1.45-8.37). Among 5,066 students who denied injecting drugs, HCV prevalence was 0.8% in those who reported intranasal drug use and 0.6% each in those who reported tattoos and those who reported body piercing. Increased HBV prevalence was associated with high-risk sexual behaviors and black or Asian race. In conclusion, there was no increased risk for HCV or HBV infection in low-risk adults based solely on history of cosmetic procedures or snorting drugs. However, proper infection control practices for cosmetic procedures should be followed, illegal drug use discouraged, and hepatitis B vaccination provided to adolescents and sexually active adults.
