Community-acquired respiratory viral infections (CARV) significantly impact patients with hematological malignancies (HM), leading to high morbidity and mortality. However, large-scale, real-world data on CARV in these patients is limited. This study analyzed data from the EPICOVIDEHA-EPIFLUEHA registry, focusing on patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season. The study assessed epidemiology, clinical characteristics, risk factors, and outcomes. The study examined 1312 patients with HM diagnosed with CARV during the 2023-2024 autumn-winter season. Of these, 59.5% required hospitalization, with 13.5% needing ICU admission. The overall mortality rate was 10.6%, varying by virus: parainfluenza (21.3%), influenza (8.8%), metapneumovirus (7.1%), RSV (5.9%), or SARS-CoV-2 (5.0%). Poor outcomes were significantly associated with smoking history, severe lymphopenia, secondary bacterial infections, and ICU admission. This study highlights the severe risk CARV poses to patients with HM, especially those undergoing active treatment. The high rates of hospitalization and mortality stress the need for better prevention, early diagnosis, and targeted therapies. Given the severe outcomes with certain viruses like parainfluenza, tailored strategies are crucial to improving patient outcomes in future CARV seasons.

Enterovirus D68 (EV-D68) infections are associated with severe respiratory disease and acute flaccid myelitis (AFM). The European Non-Polio Enterovirus Network (ENPEN) aimed to investigate the epidemiological and genetic characteristics of EV-D68 infections and its clinical impact during the fall-winter season of 2021-2022. From 19 European countries, 58 institutes reported 10 481 (6.8%) EV-positive samples of which 1004 (9.6%) were identified as EV-D68 (including 852 respiratory samples). Clinical data were reported for 969 cases; 78.9% of infections were reported in children (0-5 years); and 37.9% of cases were hospitalized. Acute respiratory distress was commonly noted (93.1%) followed by fever (49.4%). Neurological problems were observed in 6.4% of cases including 6 diagnosed with AFM. Phylodynamic/Nextstrain and phylogenetic analyses based on 694 sequences showed the emergence of 2 novel B3-derived lineages, with no regional clustering. In conclusion, we describe a large-scale European EV-D68 upsurge with severe clinical impact and the emergence of B3-derived lineages.

BACKGROUND: Human metapneumovirus (hMPV) epidemiology, clinical characteristics and risk factors for poor outcome after allogeneic stem cell transplantation (allo-HCT) remain a poorly investigated area. METHODS: This retrospective multicenter cohort study examined the epidemiology, clinical characteristics, and risk factors for poor outcomes associated with human metapneumovirus (hMPV) infections in recipients of allo-HCT. RESULTS: We included 428 allo-HCT recipients who developed 438 hMPV infection episodes between January 2012 and January 2019. Most recipients were adults (93%). hMPV infections were diagnosed at a median of 373 days after allo-HCT. The infections were categorized as upper respiratory tract disease (URTD) or lower respiratory tract disease (LRTD), with 60% and 40% of cases, respectively. Patients with hMPV LRTD experienced the infection earlier in the transplant course and had higher rates of lymphopenia, neutropenia, corticosteroid use, and ribavirin therapy. Multivariate analysis identified lymphopenia and corticosteroid use (>30 mg/d) as independent risk factors for LRTD occurrence. The overall mortality at day 30 after hMPV detection was 2% for URTD, 12% for possible LRTD, and 21% for proven LRTD. Lymphopenia was the only independent risk factor associated with day 30 mortality in LRTD cases. CONCLUSIONS: These findings highlight the significance of lymphopenia and corticosteroid use in the development and severity of hMPV infections after allo-HCT, with lymphopenia being a predictor of higher mortality in LRTD cases.

Learning from the COVID-19 pandemic and considering the effects of this pandemic, we provide recommendations that can guide towards sustainable RSV surveillance with the potential to be integrated into the broader perspective of respiratory surveillance. https://bit.ly/40TsO0G
The emergence of SARS-CoV-2 and the resulting coronavirus disease 2019 (COVID-19) pandemic has led to the reconsideration of surveillance strategies for respiratory syncytial virus (RSV) and other respiratory viruses. The COVID-19 pandemic and the non-pharmaceutical interventions for COVID-19 had a substantial impact on RSV transmission in many countries, with close to no transmission detected during parts of the usual season of 2020–2021. Subsequent relaxation of social restrictions has resulted in unusual out-of-season resurgences of RSV in several countries, causing a higher healthcare burden and often a higher proportion of hospitalisations than usual among children older than 1 year in age [1]. In case of an emerging infectious disease with pandemic potential, preparedness to scale up surveillance for the emerging disease while continuing the maintenance of surveillance activities of pre-existing seasonal diseases is necessary.
BACKGROUND: Respiratory syncytial virus (RSV) infections are one of the leading causes of lower respiratory tract infections and have a major burden on society. For prevention and control to be deployed effectively, an improved understanding of the seasonality of RSV is necessary. OBJECTIVES: The main objective of this study was to contribute to a better understanding of RSV seasonality by examining the GERi multi-country surveillance dataset. METHODS: RSV seasons were included in the analysis if they contained ≥100 cases. Seasonality was determined using the "average annual percentage" method. Analyses were performed at a subnational level for the United States and Brazil. RESULTS: We included 601 425 RSV cases from 12 countries. Most temperate countries experienced RSV epidemics in the winter, with a median duration of 10-21 weeks. Not all epidemics fit this pattern in a consistent manner, with some occurring later or in an irregular manner. More variation in timing was observed in (sub)tropical countries, and we found substantial differences in seasonality at a subnational level. No association was found between the timing of the epidemic and the dominant RSV subtype. CONCLUSIONS: Our findings suggest that geographical location or climatic characteristics cannot be used as a definitive predictor for the timing of RSV epidemics and highlight the need for (sub)national data collection and analysis.

Respiratory syncytial virus (RSV) is a common cause of acute lower respiratory tract infections and hospitalisations among young children and is globally responsible for many deaths in young children, especially in infants aged <6 months. Furthermore, RSV is a common cause of severe respiratory disease and hospitalisation among older adults. The development of new candidate vaccines and monoclonal antibodies highlights the need for reliable surveillance of RSV. In the European Union (EU), no up-to-date general recommendations on RSV surveillance are currently available. Based on outcomes of a workshop with 29 European experts in the field of RSV virology, epidemiology and public health, we provide recommendations for developing a feasible and sustainable national surveillance strategy for RSV that will enable harmonisation and data comparison at the European level. We discuss three surveillance components: active sentinel community surveillance, active sentinel hospital surveillance and passive laboratory surveillance, using the EU acute respiratory infection and World Health Organization (WHO) extended severe acute respiratory infection case definitions. Furthermore, we recommend the use of quantitative reverse transcriptase PCR-based assays as the standard detection method for RSV and virus genetic characterisation, if possible, to monitor genetic evolution. These guidelines provide a basis for good quality, feasible and affordable surveillance of RSV. Harmonisation of surveillance standards at the European and global level will contribute to the wider availability of national level RSV surveillance data for regional and global analysis, and for estimation of RSV burden and the impact of future immunisation programmes.

OBJECTIVES: Due to immunosenescence and presence of comorbidities, respiratory syncytial virus (RSV) disease burden is a major health concern in older adults, which is expected to increase with the life expectancy rise. Data on RSV burden are scarce in older adults residing in long-term care facilities, a vulnerable population living in crowded settings. Therefore, two independent prospective studies were conducted during the 2003-2004 and 2004-2005 RSV seasons to assess RSV acute respiratory illnesses (ARIs) and lower respiratory tract infections (LRTIs) in ≥ 65-year-old adults residing in long-term care facilities in the Czech Republic. METHODS: RSV ARI episodes were confirmed by polymerase chain reaction in nasal swabs collected within 3 days of symptoms onset. The mortality and morbidity of RSV-confirmed ARIs, as well as the risk factors associated with RSV-confirmed ARIs were evaluated. RESULTS: Among 1,251 participants in the 2003-2004 season (ARI surveillance between October and March), there were no RSV-positive cases in 255 ARI and 105 LRTI episodes. Among 1,280 participants in the 2004-2005 season (ARI surveillance between October and April), there were 39 and 26 RSV-positive cases in 335 ARI and 217 LRTI episodes, respectively, and RSV-positive ARI and LRTI episode incidence rates were 45.82 and 30.40 per 1,000 person-years. Among 290 RSV-negative and 39 RSV-positive ARI cases in the 2004-2005 season, 15 and 4 hospitalizations, 188 and 26 LRTIs, and 11 and 3 deaths were reported. Risk factors associated with RSV-positive ARI were female gender (odds ratio: 4.98), chronic heart failure class II (odds ratio: 2.31) and diabetes requiring insulin treatment (odds ratio: 9.82). CONCLUSIONS: These studies showed that RSV was an important cause of ARI in older adults living in long-term care facilities in the 2004-2005 season, with fluctuating yearly incidences.

BACKGROUND: Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis, which are typically transmitted via respiratory droplets, are leading causes of invasive diseases, including bacteraemic pneumonia and meningitis, and of secondary infections subsequent to post-viral respiratory disease. The aim of this study was to investigate the incidence of invasive disease due to these pathogens during the early months of the COVID-19 pandemic. METHODS: In this prospective analysis of surveillance data, laboratories in 26 countries and territories across six continents submitted data on cases of invasive disease due to S pneumoniae, H influenzae, and N meningitidis from Jan 1, 2018, to May, 31, 2020, as part of the Invasive Respiratory Infection Surveillance (IRIS) Initiative. Numbers of weekly cases in 2020 were compared with corresponding data for 2018 and 2019. Data for invasive disease due to Streptococcus agalactiae, a non-respiratory pathogen, were collected from nine laboratories for comparison. The stringency of COVID-19 containment measures was quantified using the Oxford COVID-19 Government Response Tracker. Changes in population movements were assessed using Google COVID-19 Community Mobility Reports. Interrupted time-series modelling quantified changes in the incidence of invasive disease due to S pneumoniae, H influenzae, and N meningitidis in 2020 relative to when containment measures were imposed. FINDINGS: 27 laboratories from 26 countries and territories submitted data to the IRIS Initiative for S pneumoniae (62 837 total cases), 24 laboratories from 24 countries submitted data for H influenzae (7796 total cases), and 21 laboratories from 21 countries submitted data for N meningitidis (5877 total cases). All countries and territories had experienced a significant and sustained reduction in invasive diseases due to S pneumoniae, H influenzae, and N meningitidis in early 2020 (Jan 1 to May 31, 2020), coinciding with the introduction of COVID-19 containment measures in each country. By contrast, no significant changes in the incidence of invasive S agalactiae infections were observed. Similar trends were observed across most countries and territories despite differing stringency in COVID-19 control policies. The incidence of reported S pneumoniae infections decreased by 68% at 4 weeks (incidence rate ratio 0·32 [95% CI 0·27-0·37]) and 82% at 8 weeks (0·18 [0·14-0·23]) following the week in which significant changes in population movements were recorded. INTERPRETATION: The introduction of COVID-19 containment policies and public information campaigns likely reduced transmission of S pneumoniae, H influenzae, and N meningitidis, leading to a significant reduction in life-threatening invasive diseases in many countries worldwide.

AIM: Evidence has demonstrated that breastfeeding is the optimal nutrition for infants. The present study aims to report possible associations of the duration of full or partial breastfeeding with selected health outcomes during infancy. METHODS: Data from 2304 mothers were obtained by online mother-reported questionnaires at the age of 1 year of the child, providing information on full and partial breastfeeding durations, the frequency of infant upper respiratory tract infections and possible antibiotics use, and the occurrence of allergic diseases. RESULTS: Overall breastfeeding initiation rates (i.e. including both partial and full breastfeeding rates counted together) were 97.8%, declined to 95.1% at the age of 3 months, and remained as high as 90.0% at 6 months. At 1 year, 74.7% of children were still partially breastfed. There was no significant benefit of either full or partial breastfeeding over formula feeding for upper respiratory tract infection rates. Fully breastfed children had a significantly lower risk of early exposure to antibiotics when compared with either partially breastfed (odds ratio, OR: 0.74; 95% CI: 0.56, 1.00, P = 0.048) or formula-fed (OR: 0.67; 95% CI: 0.46, 1.0, P = 0.047) children. We found a neutral effect of breastfeeding on the development of allergies. CONCLUSIONS: Although no significant association between either full or partial breastfeeding versus formula feeding and the occurrence of respiratory infections during infancy was found, we demonstrated a significantly lower risk of early exposure to antibiotics in fully breastfed children when compared with those either partially breastfed or formula-fed.

BACKGROUND: Monitoring changes in the epidemiology of cystic fibrosis (CF) pathogens is essential for clinical research, quality improvement, and clinical management. METHODS: We analyzed data reported to the European Cystic Fibrosis Society Patient Registry (ECFSPR) from 2011 to 2016 to determine the overall and the age-specific annual prevalence and incidence of selected CF pathogens and their trends during these years. The ECFSPR collects data on three chronic infections: Pseudomonas aeruginosa (PsA), Burkholderia cepacia complex Species (BCC) and Staphylococcus aureus (SA), as well as on the occurrence of non-tuberculous mycobacteria (NTM) and Stenotrophomonas maltophilia (SM). The same analyses were performed for different country groups, according to their gross national income (GNI). RESULTS: The pathogens with the highest prevalence were SA and PsA, with prevalence, in 2016, equal to 38.3% and 29.8% respectively, followed by SM (8.1%). The pathogens with the lowest prevalence were NTM (3.3%) and BCC (3.1%). The overall prevalence and incidence significantly decreased for PsA; they also decreased for BCC, while they increased significantly for SA. The overall prevalence of NTM and SM increased significantly. The most considerable prevalence changes were observed for PsA, which decreased across all income country groups and all age strata (with the exception of 0-1 years) The prevalence and incidence of pathogens differed significantly according to GNI. CONCLUSIONS: The epidemiology of CF pathogens in Europe has changed; epidemiologic data differ significantly among countries with different socio-economic status. The causes of these observations are multifactorial and include improvements in clinical care and infection control.
