Introduction Respiratory syncytial virus (RSV) causes a substantial disease burden among infants. In older children and adults, incidence is underestimated due to nonspecific symptoms and limited standard-of-care testing. We aimed to estimate RSV-attributable hospitalizations and deaths in Spain during 2016–2019. Methods Nationally representative hospitalization and mortality databases were obtained from the Ministry of Health and the National Statistical Office. A quasi-Poisson regression model was fitted to estimate the number of hospitalizations and deaths attributable to RSV as a function of periodic and aperiodic time trends and viral activity, while allowing for potential overdispersion. Results In children, the RSV-attributable respiratory hospitalization incidence was highest among infants aged 0–5 months (3998–5453 cases/100,000 person-years, representing 72% of all respiratory hospitalizations) and decreased with age. In 2019, estimated rates in children 0–5, 6–11, 12–23 months and 6–17 years were approximately 1.3, 1.4, 1.5, and 6.5 times higher than those based on standard-of-care RSV-specific codes. In adults, the RSV-attributable cardiorespiratory hospitalization rate increased with age and was highest among persons ≥ 80 years (1325–1506 cases/100,000, 6.5% of all cardiorespiratory hospitalizations). In 2019, for persons aged 18–49, 50–59, 60–79, and ≥ 80 years, estimated rates were approximately 8, 6, 8, and 16 times higher than those based on standard-of-care RSV-specific codes. The RSV-attributable cardiorespiratory mortality rate was highest among ≥ 80 age group (126–150 deaths/100,000, 3.5–4.1% of all cardiorespiratory deaths), when reported mortality rate ranged between 0 and 0.5/100,000. Conclusions When accounting for under-ascertainment, estimated RSV-attributable hospitalizations were higher than those reported based on standard-of-care RSV-specific codes in all age groups but particularly among older children and older adults. Like other respiratory viruses, RSV contributes to both respiratory and cardiovascular complications. Efficacious RSV vaccines could have a high public health impact in these age and risk groups.

First study of social inequalities in tobacco-attributable mortality (TAM) in Spain considering the joint influence of sex, age, and education (intersectional perspective). Data on all deaths due to cancer, cardiometabolic and respiratory diseases among people aged ≥35 years in 2016 were obtained from the Spanish Statistical Office. TAM was calculated based on sex-, age- and education-specific smoking prevalence, and on sex-, age- and disease-specific relative risks of death for former and current smokers vs lifetime non-smokers. As inequality measures, the relative index of inequality (RII) and the slope index of inequality (SII) were calculated using Poisson regression. The RII is interpreted as the relative risk of mortality between the lowest and the highest educational level, and the SII as the absolute difference in mortality. The crude TAM rate was 55 and 334 per 100,000 in women and men, respectively. Half of these deaths occurred among people with the lowest educational level (27% of the population). The RII for total mortality was 0.39 (95%CI: 0.35-0.42) in women and 1.61 (95%CI: 1.55-1.67) in men. The SII was -41 and 111 deaths per 100,000, respectively. Less-educated women aged <55 years and men (all ages) showed an increased mortality risk; nonetheless, less educated women aged ≥55 had a reduced risk. TAM is inversely associated with educational level in men and younger women, and directly associated with education in older women. This could be explained by different smoking patterns. Appropriate tobacco control policies should aim to reduce social inequalities in TAM.

Introduction We aimed to describe the risk profile of respiratory syncytial virus (RSV) infections among adults ≥ 60 years in Valladolid from January 2010 to August 2022, and to compare them with influenza and COVID-19 controls. Methods This was a retrospective cohort study of all laboratory-confirmed RSV infections identified in centralized microbiology database during a 12-year period. We analyzed risk factors for RSV hospitalization and severity (length of stay, intensive care unit admission, in-hospital death or readmission < 30 days) and compared severity between RSV patients vs. influenza and COVID-19 controls using multivariable logistic regression models. Results We included 706 RSV patients (635 inpatients and 71 outpatients), and 598 influenza and 60 COVID-19 hospitalized controls with comparable sociodemographic profile. Among RSV patients, 96 (15%) had a subtype identified: 56% A, 42% B, and 2% A + B. Eighty-one percent of RSV patients had cardiovascular conditions, 65% endocrine/metabolic, 46% chronic lung, and 43% immunocompromising conditions. Thirty-six percent were coinfected (vs. 21% influenza and 20% COVID-19; p  =  < .0001 and 0.01). Ninety-two percent had signs of lower respiratory infection (vs. 85% influenza and 72% COVID-19, p  =  < .0001) and 27% cardiovascular signs (vs. 20% influenza and 8% COVID-19, p  = 0.0031 and 0.0009). Laboratory parameters of anemia, inflammation, and hypoxemia were highest in RSV. Among RSV, being a previous smoker (adjusted OR 2.81 [95% CI 1.01, 7.82]), coinfection (4.34 [2.02, 9.34]), and having cardiovascular (3.79 [2.17, 6.62]), neurologic (2.20 [1.09, 4.46]), or chronic lung (1.93 [1.11, 3.38]) diseases were risks for hospitalization. Being resident in care institutions (1.68 [1.09, 2.61]) or having a coinfection (1.91[1.36, 2.69]) were risks for higher severity, while RSV subtype was not associated with severity. Whereas RSV and influenza patients did not show differences in severity, RSV patients had 68% (38–84%) lower odds of experiencing any severe outcome compared to COVID-19. Conclusions RSV especially affects those with comorbidities, coinfections, and living in care institutions. RSV vaccination could have an important public health impact in this population.

Introduction We aimed to describe the risk profile of RSV infections among children aged ≤ 24 months in Valladolid from January 2010 to August 2022 and to compare them with influenza and COVID-19 controls. Methods We conducted a retrospective cohort study of all laboratory-confirmed RSV, influenza, and COVID-19 infections. We analyzed risk factors for RSV hospitalization and severity (length-of-stay ≥ 8 days, intensive-care-unit admission, in-hospital death or readmission < 30 days) and compared severity between hospitalized RSV patients vs. influenza and COVID-19 controls using multivariable logistic regression models. Results We included 1507 patients with RSV (1274 inpatient), 32 with influenza, and 52 COVID-19 controls. Hospitalized RSV (mean age 5.3 months) and COVID-19 (4 months) were younger than influenza (9.1 months) patients. Sixteen percent of patients had RSV within the first month of life. Most infants did not have comorbidities (74% RSV, 56% influenza, and 69% COVID-19). Forty-one percent of patients with RSV and influenza were coinfected vs. 27% COVID-19 ( p  = 0.04). Among RSV, hospitalization risk factors were prematurity (adjusted OR 3.11 [95% CI 1.66, 4.44]) and coinfection (2.03 [1.45, 2.85]). Risks for higher severity were maternal smoking (1.89 [1.07, 3.33]), prematurity (2.31 [1.59, 3.34]), chronic lung disease (2.20 [1.06, 4.58]), neurodevelopmental condition (4.28 [2.10, 8.73]), and coinfection (2.67 [2.09, 3.40]). Breastfeeding was protective against hospitalization (0.87 [0.80, 0.95]) and severity (0.81 [0.74, 0.88]), while complete vaccination schedule was protective against severity (0.51 [0.27, 0.97]). RSV had 2.47 (1.03, 5.96) higher risk of experiencing any severe outcome compared to influenza and did not show significant differences vs. COVID-19. Conclusions RSV hospitalizations were more frequent and severe than influenza, while severity was comparable to the early pandemic COVID-19. Currently, both influenza and COVID-19 vaccines are included in the maternal and childhood Spanish immunization schedule between the ages of 6 and 59 months. RSV monoclonal antibody is recommended for ≤ 6 months but a third of patients were aged 6–24 months. Maternal RSV vaccination can protect their children directly from birth and indirectly through breastfeeding.

Recent international communicable disease crises have highlighted the need for countries to assure their preparedness to respond effectively to public health emergencies. The objective of this study was to critically review existing tools to support a country’s assessment of its health emergency preparedness. We developed a framework to analyze the expected effectiveness and utility of these tools. Through mixed search strategies, we identified 12 tools with relevance to public health emergencies. There was considerable consensus concerning the critical preparedness system elements to be assessed, although their relative emphasis and means of assessment and measurement varied considerably. Several tools identified appeared to have reporting requirements as their primary aim, rather than primary utility for system self-assessment of the countries and states using the tool. Few tools attempted to give an account of their underlying evidence base. Only some tools were available in a user-friendly electronic modality or included quantitative measures to support the monitoring of system preparedness over time. We conclude there is still a need for improvement in tools available for assessment of country preparedness for public health emergencies, and for applied research to increase identification of system measures that are valid indicators of system response capability.
