Progress Toward Achieving National HIV/AIDS Strategy Goals for Quality of Life Among Persons Aged ≥50 Years with Diagnosed HIV - Medical Monitoring Project, United States, 2017-2023.

Ensuring good quality of life (QoL) among persons with diagnosed HIV (PWH) is a priority of the National HIV/AIDS Strategy (NHAS), which established 2025 goals for improving QoL. Goals are monitored through five indicators: self-rated health, unmet needs for mental health services, unemployment, hunger or food insecurity, and unstable housing or homelessness. Among the growing population of PWH aged ≥50 years, progress toward these goals has not been assessed. Data collected during the 2017-2022 cycles of the Medical Monitoring Project, an annual complex sample survey of U.S. adults with diagnosed HIV, assessed progress toward NHAS 2025 QoL goals among PWH aged ≥50 years, overall and by age group. The recent estimated annual percentage change from baseline (2017 or 2018) to 2022 was calculated for each indicator. Among PWH aged ≥50 years, the 2025 goal of 95% PWH with good or better self-rated health is 46.2% higher than the 2022 estimate. The 2025 goals of a 50% reduction in the other indicators range from 26.3% to 56.3% lower than the 2022 estimates. Decreasing hunger or food insecurity by 50% among PWH aged ≥65 was the only goal met by 2022. If recent trends continue, other NHAS QoL 2025 goals are unlikely to be met. Multisectoral strategies to improve access to housing, employment, food, and mental health will be needed to meet NHAS 2025 goals for QoL among older PWH.

Risk Factors for Ebola Virus Persistence in Semen of Survivors in Liberia.

BACKGROUND: Long-term persistence of Ebola virus (EBOV) in immunologically privileged sites has been implicated in recent outbreaks of Ebola virus disease (EVD) in Guinea and the Democratic Republic of Congo. This study was designed to understand how the acute course of EVD, convalescence, and host immune and genetic factors may play a role in prolonged viral persistence in semen. METHODS: A cohort of 131 male EVD survivors in Liberia were enrolled in a case-case study. "Early clearers" were defined as those with 2 consecutive negative EBOV semen test results by real-time reverse-transcription polymerase chain reaction (rRT-PCR) ≥2 weeks apart within 1 year after discharge from the Ebola treatment unit or acute EVD. "Late clearers" had detectable EBOV RNA by rRT-PCR >1 year after discharge from the Ebola treatment unit or acute EVD. Retrospective histories of their EVD clinical course were collected by questionnaire, followed by complete physical examinations and blood work. RESULTS: Compared with early clearers, late clearers were older (median, 42.5 years; P < .001) and experienced fewer severe clinical symptoms (median 2, P = .006). Late clearers had more lens opacifications (odds ratio, 3.9 [95% confidence interval, 1.1-13.3]; P = .03), after accounting for age, higher total serum immunoglobulin G3 (IgG3) titers (P = .005), and increased expression of the HLA-C*03:04 allele (0.14 [.02-.70]; P = .007). CONCLUSIONS: Older age, decreased illness severity, elevated total serum IgG3 and HLA-C*03:04 allele expression may be risk factors for the persistence of EBOV in the semen of EVD survivors. EBOV persistence in semen may also be associated with its persistence in other immunologically protected sites, such as the eye.

Assessment of Anti-SARS-CoV-2 antibody levels among university students vaccinated with different COVID-19 primary and booster doses - fall 2021, Wisconsin.

BACKGROUND: University students commonly received COVID-19 vaccinations before returning to U.S. campuses in the Fall of 2021. Given likely immunologic variation among students based on differences in type of primary series and/or booster dose vaccine received, we conducted serologic investigations in September and December 2021 on a large university campus in Wisconsin to assess anti-SARS-CoV-2 antibody levels. METHODS: We collected blood samples, demographic information, and COVID-19 illness and vaccination history from a convenience sample of students. Sera were analyzed for both anti-spike (anti-S) and anti-nucleocapsid (anti-N) antibody levels using World Health Organization standardized binding antibody units per milliliter (BAU/mL). Levels were compared across categorical primary COVID-19 vaccine series received and binary COVID-19 mRNA booster status. The association between anti-S levels and time since most recent vaccination dose was estimated by mixed-effects linear regression. RESULTS: In total, 356 students participated, of whom 219 (61.5%) had received a primary vaccine series of Pfizer-BioNTech or Moderna mRNA vaccines and 85 (23.9%) had received vaccines from Sinovac or Sinopharm. Median anti-S levels were significantly higher for mRNA primary vaccine series recipients (2.90 and 2.86 log [BAU/mL], respectively), compared with those who received Sinopharm or Sinovac vaccines (1.63 and 1.95 log [BAU/mL], respectively). Sinopharm and Sinovac vaccine recipients were associated with a significantly faster anti-S decline over time, compared with mRNA vaccine recipients (P <.001). By December, 48/172 (27.9%) participants reported receiving an mRNA COVID-19 vaccine booster, which reduced the anti-S antibody discrepancies between primary series vaccine types. CONCLUSIONS: Our work supports the benefit of heterologous boosting against COVID-19. COVID-19 mRNA vaccine booster doses were associated with increases in anti-SARS-CoV-2 antibody levels; following an mRNA booster dose, students with both mRNA and non-mRNA primary series receipt were associated with comparable levels of anti-S IgG.

A cohort study measuring SARS-CoV-2 seroconversion and serial viral testing in university students.

BACKGROUND: To improve understanding of the antibody response to SARS-CoV-2 infection, we examined seroprevalence, incidence of infection, and seroconversion among a cohort of young adults living on university campuses during the fall of 2020. METHODS: At the beginning (semester start) and end (semester end) of an 11-week period, serum collected from 107 students was tested using the qualitative Abbott Architect SARS-CoV-2 IgG and AdviseDx SARS-CoV-2 IgG II assays. Results were matched to interim weekly surveillance viral testing and symptom data. RESULTS: With the SARS-CoV-2 IgG assay, 15 (14.0%) students were seropositive at semester start; 29 (27.1%) students were seropositive at semester end; 10 (9.3%) were seropositive at both times. With the AdviseDx SARS-CoV-2 IgG II assay, 17 (16.3%) students were seropositive at semester start, 37 (35.6%) were seropositive at semester end, and 16 (15.3%) were seropositive at both times. Overall, 23 students (21.5%) had positive viral tests during the semester. Infection was identified by serial testing in a large majority of individuals who seroconverted using both assays. Those seropositive at semester end more frequently reported symptomatic infections (56.5%) than asymptomatic infections (30.4%). CONCLUSION: Differences between antibody targets were observed, with more declines in antibody index values below the threshold of positivity with the anti-nucleocapsid assay compared to the anti-spike assay. Serology testing, combined with serial viral testing, can detect seroconversions, and help understand the potential correlates of protection provided by antibodies to SARS-CoV-2.

Characteristics of Ebola Virus Disease Survivor Blood and Semen in Liberia: Serology and Reverse Transcription Polymerase Chain Reaction (RT-PCR).

INTRODUCTION: Ebola virus (EBOV), species Zaire ebolavirus, may persist in the semen of male survivors of Ebola virus disease (EVD). We conducted a study of male survivors of the 2014-2016 EVD outbreak in Liberia and evaluated their immune responses to EBOV. We report here findings from the serologic testing of blood for EBOV-specific antibodies, molecular testing for EBOV in blood and semen, and serologic testing of peripheral blood mononuclear cells (PBMCs) in a subset of study participants. METHODS: We tested for EBOV RNA in blood by quantitative reverse transcription polymerase chain reaction (qRT-PCR), and for anti-EBOV-specific immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies by enzyme-linked immunosorbent assay (ELISA) for 126 study participants. We performed PBMC analysis on a subgroup of 26 IgG-negative participants. RESULTS: All 126 participants tested negative for EBOV RNA in blood by qRT-PCR. The blood of 26 participants tested negative for EBOV-specific IgG antibodies by ELISA. PBMCs were collected from 23/26 EBOV IgG-negative participants. Of these, 1/23 participants had PBMCs that produced anti-EBOV-specific IgG antibodies upon stimulation with EBOV-specific glycoprotein (GP) and nucleoprotein (NP) antigens. CONCLUSIONS: The blood of EVD survivors, collected when they did not have symptoms meeting the case definition for acute or relapsed EVD, is unlikely to pose a risk for EBOV transmission. We identified 1 IgM/IgG negative participant who had PBMCs that produced anti-EBOV-specific antibodies upon stimulation. Immunogenicity following acute EBOV infection may exist along a spectrum, and absence of antibody response should not be exclusionary in determining an individual's status as a survivor of EVD.

Assessment of State, Local, and Territorial Zika Planning and Preparedness Activities - United States, June 2016-July 2017.

The emergency response to Zika virus disease required coordinated efforts and heightened collaboration among federal, state, local, and territorial public health jurisdictions. CDC activated its Emergency Operations Center on January 21, 2016, with seven task forces to support the national response. The State Coordination Task Force, which functions as a liaison between jurisdictions and federal operations during a response, coordinated the development of CDC Guidelines for Development of State and Local Risk-based Zika Action Plans, which included a Zika Preparedness Checklist (1). The checklist summarized recommendations covering topics from the seven task forces. In July 2016, CDC's Office of Public Health Preparedness and Response (OPHPR) awarded $25 million in supplemental funding to 53 jurisdictions (41 states, eight territories, and four metropolitan areas) to support Zika preparedness and response activities. In December 2016, CDC awarded an additional $25 million to 21 of the 53 jurisdictions at the greatest risk for seeing Zika in their communities based on the presence of the mosquito responsible for spreading Zika, history of local transmission, or a high volume of travelers from Zika-affected areas. The additional $25 million was part of the $350 million in Zika supplemental funding provided to CDC by Congress in 2016* (2,3). Funded jurisdictions reported progress through the checklist at five quarterly points throughout the response. Data were analyzed to assess planning and response activities. Among the 53 jurisdictions, the percentage that reported having a Zika virus readiness, response, and recovery plan increased from 26% in June 2016 to 64% in July 2017. Overall, Zika planning and response activities increased among jurisdictions from June 2016 to July 2017. The recent Zika virus outbreak underscores the importance of strengthening state, local, and territorial health department capacity for rapid response to emerging threats.

Monitoring of Persons with Risk for Exposure to Ebola Virus - United States, November 3, 2014-December 27, 2015.

During November 3, 2014-December 27, 2015, CDC implemented guidance on movement and monitoring of persons in the United States with potential exposure to Ebola virus (Ebola) (1). Monitoring was concluded in December 2015. After CDC modified the guidance for monitoring travelers from Guinea (the last country for which monitoring of travelers was recommended) in late December 2015, jurisdictional reports were no longer collected by CDC. This report documents the number of persons monitored as part of the effort to isolate, test, and, if necessary, treat symptomatic travelers and other persons in the United States who had risk for exposure to Ebola during the period the guidance was in effect. Sixty jurisdictions, including all 50 states, two local jurisdictions, and eight territories and freely associated states, reported a total of 29,789 persons monitored, with >99% completing 21-day monitoring with no loss to follow-up exceeding 48 hours. No confirmed cases of imported Ebola were reported once monitoring was initiated. This landmark public health response demonstrates the robust infrastructure and sustained monitoring capacity of local, state, and territorial health authorities in the United States as a part of a response to an international public health emergency.

Clinical Outcomes of Adults With Diagnosed HIV Living in Ending the HIV Epidemic Priority Areas, Medical Monitoring Project, 2018.

OBJECTIVES: The Ending the HIV Epidemic (EHE) initiative prioritizes treatment and prevention efforts in counties where most new HIV diagnoses occur and states with substantial incidence of new HIV diagnoses in rural areas. Understanding the characteristics of adults with HIV living in EHE priority areas, and how these characteristics compare with adults with HIV living in non-EHE priority areas, can inform EHE efforts. METHODS: We analyzed data from the 2018 Medical Monitoring Project (MMP) to understand the characteristics of adults with HIV living in 36 of 48 EHE priority counties; San Juan, Puerto Rico; and 1 of 7 EHE priority states. We calculated weighted percentages of sociodemographic characteristics, behaviors, and clinical outcomes of adults with diagnosed HIV living in MMP EHE priority areas and compared them with characteristics of adults who did not live in MMP EHE priority areas using prevalence ratios (PRs) with predicted marginal means. RESULTS: Living in an MMP EHE priority area was more common among adults who were non-Hispanic Black or Hispanic, experienced homelessness, or were food insecure compared with adults who were non-Hispanic White (59.3% and 58.4% vs 41.0%), not experiencing homelessness (60.9% vs 51.9%), or not food insecure (59.8% vs 51.0%). Adults who lived in MMP EHE priority areas were significantly less likely to be adherent to their HIV medications (PR = 0.95; 95% CI, 0.91-0.99) and durably virally suppressed (PR = 0.94; 95% CI, 0.91-0.97), and more likely to miss scheduled appointments for HIV care (PR = 1.31; 95% CI, 1.10-1.56) than adults who did not live in MMP EHE priority areas. CONCLUSION: To increase viral suppression and reduce HIV transmission, it is essential to strengthen public health efforts to improve medication and appointment adherence in this population.

Risk Factors for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection and Presence of Anti-SARS-CoV-2 Antibodies Among University Student Dormitory Residents, September-November 2020.

BACKGROUND: Multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks occurred at universities during Fall 2020, but little is known about risk factors for campus-associated infections or immunity provided by anti-SARS-CoV-2 antibodies in young adults. METHODS: We conducted surveys and serology tests among students living in dormitories in September and November to examine infection risk factors and antibody presence. Using campus weekly reverse-transcription polymerase chain reaction (RT-PCR) test results, the relationship between survey responses, SARS-CoV-2 antibodies, and infections was assessed. RESULTS: Of 6136 students, 1197 completed the survey and 572 also completed serologic testing in September compared with 517 and 414 in November, respectively. Participation in fraternity or sorority events (adjusted risk ratio [aRR], 1.9 [95% confidence interval {CI}, 1.4-2.5]) and frequent alcohol consumption (aRR, 1.6 [95% CI, 1.2-2.2]) were associated with SARS-CoV-2 infection. Mask wearing during social events (aRR, 0.6 [95% CI, .6-1.0]) was associated with decreased risk. None of the 20 students with antibodies in September tested positive for SARS-CoV-2 during the semester, while 27.8% of students who tested RT-PCR positive tested negative for antibodies in November. CONCLUSIONS: Frequent drinking and attending social events were associated with SARS-CoV-2 infection. Antibody presence in September appeared to be protective from reinfection, but this finding was not statistically significant.
