Background Influenza remains an important cause of hospitalizations in the United States. Estimating the number of influenza hospitalizations is vital for public health decision making. Combining existing surveillance systems through capture-recapture methods allows for more comprehensive burden estimations. Methods Data from independent surveillance systems were combined using capture-recapture methods to estimate influenza hospitalization rates for children and adults in Middle Tennessee during consecutive influenza seasons from 2016–2017 through 2019–2020. The Emerging Infections Program (EIP) identified cases through surveillance of laboratory results for hospitalized children and adults. The Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) and New Vaccine Surveillance Network (NVSN) recruited hospitalized patients with respiratory symptoms or fever. Population-based influenza rates and the proportion of cases detected by each surveillance system were calculated. Results Estimated overall influenza hospitalization rates ranged from 23 influenza-related hospitalizations per 10 000 persons in 2016–2017 to 40 per 10 000 persons in 2017–2018. Adults aged ≥65 years had the highest hospitalization rates across seasons and experienced a rate of 170 hospitalizations per 10 000 persons during the 2017–2018 season. EIP consistently identified a higher proportion of influenza cases for adults and children compared with HAIVEN and NVSN, respectively. Conclusions Current surveillance systems underestimate the influenza burden. Capture-recapture provides an alternative approach to use data from independent surveillance systems and complement population-based burden estimates. [ABSTRACT FROM AUTHOR]

Introduction: Traditional surveillance systems may underestimate the burden caused by respiratory syncytial virus (RSV). Capture–recapture methods provide alternatives for estimating the number of RSV‐related hospitalizations in a population. Methods: Capture–recapture methods were used to estimate the number of RSV‐related hospitalizations in adults in Middle Tennessee from two independent hospitalization surveillance systems during consecutive respiratory seasons from 2016–2017 to 2019–2020. Data from the Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) and the Emerging Infections Program (EIP) were used. Annual RSV hospitalization rates were calculated using the capture–recapture estimates weighted by hospitals' market share divided by the corresponding census population. Results: Using capture–recapture methods, the estimated overall adult hospitalization rates varied from 8.3 (95% CI: 5.9–15.4) RSV‐related hospitalizations per 10,000 persons during the 2016–2017 season to 28.4 (95% CI: 18.2–59.0) hospitalizations per 10,000 persons in the 2019–2020 season. The proportion of hospitalizations that HAIVEN determined ranged from 8.7% to 36.7% of the total capture–recapture estimated hospitalization, whereas EIP detected 23.5% to 52.7% of the total capture–recapture estimated hospitalizations. Conclusion: Capture–recapture estimates showed that individual traditional surveillance systems underestimated the hospitalization burden in adults. Using capture–recapture allows for a more comprehensive estimate of RSV hospitalizations. [ABSTRACT FROM AUTHOR]

Background Novel coronavirus disease 2019 (COVID-19) is frequently compared with influenza. The Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) conducts studies on the etiology and characteristics of U.S. hospitalized adults with influenza. It began enrolling patients with COVID-19 hospitalizations in March 2020. Patients with influenza were compared with those with COVID-19 in the first months of the U.S. epidemic. Methods Adults aged ≥ 18 years admitted to hospitals in 4 sites with acute respiratory illness were tested by real-time reverse transcription polymerase chain reaction for influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing COVID-19. Demographic and illness characteristics were collected for influenza illnesses during 3 seasons 2016–2019. Similar data were collected on COVID-19 cases admitted before June 19, 2020. Results Age groups hospitalized with COVID-19 (n = 914) were similar to those admitted with influenza (n = 1937); 80% of patients with influenza and 75% of patients with COVID-19 were aged ≥50 years. Deaths from COVID-19 that occurred in younger patients were less often related to underlying conditions. White non-Hispanic persons were overrepresented in influenza (64%) compared with COVID-19 hospitalizations (37%). Greater severity and complications occurred with COVID-19 including more ICU admissions (AOR = 15.3 [95% CI: 11.6, 20.3]), ventilator use (AOR = 15.6 [95% CI: 10.7, 22.8]), 7 additional days of hospital stay in those discharged alive, and death during hospitalization (AOR = 19.8 [95% CI: 12.0, 32.7]). Conclusions While COVID-19 can cause a respiratory illness like influenza, it is associated with significantly greater severity of illness, longer hospital stays, and higher in-hospital deaths.

Background: Influenza causes significant morbidity and mortality and stresses hospital resources during periods of increased circulation. We evaluated the effectiveness of the 2019-2020 influenza vaccine against influenza-associated hospitalization in the United States.Methods: We included adults hospitalized with acute respiratory illness at 14 hospitals and tested for influenza viruses by reserve-transcription polymerase chain reaction. Vaccine effectiveness (VE) was estimated by comparing the odds of current-season influenza vaccination in test-positive influenza cases vs test-negative controls, adjusting for confounders. VE was stratified by age and major circulating influenza types along with A(H1N1)pdm09 genetic subgroups.Results: A total of 3116 participants were included, including 18% (n = 553) influenza-positive cases. Median age was 63 years. Sixty-seven percent (n = 2079) received vaccination. Overall adjusted VE against influenza viruses was 41% (95% confidence interval [CI], 27%-52%). VE against A(H1N1)pdm09 viruses was 40% (95% CI, 24%-53%) and 33% against B viruses (95% CI, 0-56%). Of the 2 major A(H1N1)pdm09 subgroups (representing 90% of sequenced H1N1 viruses), VE against one group (5A + 187A,189E) was 59% (95% CI, 34%-75%) whereas no VE was observed against the other group (5A + 156K) (-1% [95% CI, -61% to 37%]).Conclusions: In a primarily older population, influenza vaccination was associated with a 41% reduction in risk of hospitalized influenza illness.

Background Demonstration of influenza vaccine effectiveness (VE) against hospitalized illness in addition to milder outpatient illness may strengthen vaccination messaging. Our objective was to compare patient characteristics and VE between United States (US) inpatient and outpatient VE networks. Methods We tested adults with acute respiratory illness (ARI) for influenza within 1 outpatient-based and 1 hospital-based VE network from 2015 through 2018. We compared age, sex, and high-risk conditions. The test-negative design was used to compare vaccination odds in influenza-positive cases vs influenza-negative controls. We estimated VE using logistic regression adjusting for site, age, sex, race/ethnicity, peak influenza activity, time to testing from, season (overall VE), and underlying conditions. VE differences (ΔVE) were assessed with 95% confidence intervals (CIs) determined through bootstrapping with significance defined as excluding the null. Results The networks enrolled 14 573 (4144 influenza-positive) outpatients and 6769 (1452 influenza-positive) inpatients. Inpatients were older (median, 62 years vs 49 years) and had more high-risk conditions (median, 4 vs 1). Overall VE across seasons was 31% (95% CI, 26%–37%) among outpatients and 36% (95% CI, 27%–44%) among inpatients. Strain-specific VE (95% CI) among outpatients vs inpatients was 37% (25%–47%) vs 53% (37%–64%) against H1N1pdm09; 19% (9%–27%) vs 23% (8%–35%) against H3N2; and 46% (38%–53%) vs 46% (31%–58%) against B viruses. ΔVE was not significant for any comparison across all sites. Conclusions Inpatients and outpatients with ARI represent distinct populations. Despite comparatively poor health among inpatients, influenza vaccination was effective in preventing influenza-associated hospitalizations. [ABSTRACT FROM AUTHOR]

Background: The influenza vaccine is one of the best ways to prevent influenza infection, but little is known about influenza vaccine failure.Methods: This study evaluated patients admitted for acute respiratory illness during 2015-2019 influenza seasons to compare vaccinated influenza-negative to vaccinated influenza-positive patients. Statistical analyses were performed with STATA and R using Pearson χ 2, Kruskal-Wallis, Wilcoxon rank-sum tests, and multivariate logistic regression.Results: Of 1236 enrolled patients vaccinated for influenza, 235 (19%) tested positive for influenza. Demographics, vaccines, and comorbidities were similar between groups except for morbid obesity (13% influenza negative vs 8%, P = .04), and immunosuppression (63% influenza positive vs 54%, P = .01). Logistic regression analysis demonstrated older patients (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.03-2.10) and immunosuppressed patients (OR, 1.56; 95% CI, 1.15-2.12) were at increased risk for influenza despite immunization. When evaluated by influenza subtype, immunosuppression increased the risk for influenza A/H3N2 (OR, 1.86; 95% CI, 1.25-2.75).Conclusions: Our study demonstrated increased risk of influenza vaccine failure in older patients and immunosuppressed patients. These groups are also at increased risk for influenza complications. To improve protection of patients against influenza illnesses, more effective vaccines and strategies are needed.

- Abstract
Human herpesvirus type 6 (HHV-6) has been well described as an agent of meningoencephalitis in post-haematopoietic stem cell transplantation patients, but is a rare cause of meningoencephalitis in immunocompetent adults. We report an immunocompetent adult with HHV-6-associated meningoencephalitis. The patient was an elderly diabetic man who presented with fever and confusion, with cerebrospinal fluid (CSF) pleocytosis. HHV-6 DNA was amplified from CSF by polymerase chain reaction. In our review of the medical literature we examine clinical presentations, laboratory findings, neuroimaging studies, treatments and clinical outcomes in immunocompetent patients with HHV-6 meningoencephalitis.
