Pediatric patients with "once-daily" fevers are often referred to pediatric infectious disease specialists for evaluation. Often, these fevers occur at nighttime in the absence of additional symptoms and come to the caregiver's attention after a viral illness. It is crucial for caregivers and providers to be able to define and measure fever accurately when trying to ascertain the true etiology of this clinical picture. Fever education is critical in providing reassurance to parents, and fever diaries should be encouraged. In a well-appearing child without any additional symptoms, at least a percentage of these fevers can be explained by normal diurnal variation of temperature. [Pediatr Ann. 2022;51(5):e202-e205.].

Children account for a growing share of coronavirus disease 2019 (COVID-19) infections in the United States. Since the widespread availability of COVID-19 vaccine in adults, there has been an upward trend of cases in children, accounting for approximately 20% of the weekly new cases. The majority (38.3%) reported in high school students age 14 to 17 years. Children are also at risk of a postinflammatory condition, known as multisystem inflammatory syndrome in children, after COVID-19. In addition, infected children could transmit the virus to vulnerable adults, contributing to ongoing pandemic. We believe that children need to be vaccinated against COVID-19 and review the available evidence. [Pediatr Ann. 2022;51(5):e180-e185.].

Influenza A virus (IAV) is a major cause of respiratory infections worldwide, with the most severe cases occurring in the very young and in elderly individuals [...].

Purpose of Study We studied the risk of apnea in otherwise healthy infants < 6 mo based on severity of illness at presentation. We also compared clinical courses between mild and severe disease groups. Methods Used This is a retrospective chart review of infants evaluated in the emergency department (ED) over 3 consecutive RSV seasons: 2017-2018, 2018-2019, and 2019-2020. We included infants < 6 mo with RSV diagnosed using multiplex PCR assay. Infants with history of prematurity ( 37 weeks), past apnea, chronic lung disease, heart disease, airway anomalies, neuromuscular diseases, and genetic disorders were excluded. Clinical data were reviewed to separate patients into mild or severe cases. Infants with respiratory rate (RR) >= 60, retractions, oxygen saturation < 90%, poor oral intake, or dehydration were classified as severe. Summary of Results A total of 161 infants met study criteria: 52 mild and 109 severe. There was no risk of apnea in mild cases and low risk in severe cases. Significant differences included length of stay (LOS), oxygen requirement, ICU admission, and hospital readmission (table 1). About 59% of severe cases required oxygen support, the majority of which received high flow nasal cannula, while 29% of mild cases required support and most were placed on regular nasal cannula (table 2). Twenty-seven severe cases required ICU and LOS was 1 day longer than mild. Forty-two severe cases were readmitted after initial discharge compared to 2 mild cases. Conclusions There was a low incidence of apnea in full term infants < 6 mo with RSV regardless of severity of disease, suggesting that risk of apnea is not a reliable factor when considering hospital admission. Conversely, high RR, retractions, hypoxia on presentation, poor PO intake, and dehydration were specific to severe RSV disease. The differences in oxygen support, ICU admission, and readmission emphasize the importance of identifying mild versus severe RSV to anticipate clinical courses. Further studies are needed to standardize and validate characteristics of RSV that require hospitalization. (Table Presented)

INTRODUCTION/UNASSIGNED:The high burden of respiratory syncytial virus (RSV) infection in young children disproportionately occurs in low- and middle-income countries (LMICs). The PROUD (Preventing RespiratOry syncytial virUs in unDerdeveloped countries) Taskforce of 24 RSV worldwide experts assessed key needs for RSV prevention in LMICs, including vaccine and newer preventive measures. METHODS/UNASSIGNED:A global, survey-based study was undertaken in 2021. An online questionnaire was developed following three meetings of the Taskforce panellists wherein factors related to RSV infection, its prevention and management were identified using iterative questioning. Each factor was scored, by non-panellists interested in RSV, on a scale of zero (very-low-relevance) to 100 (very-high-relevance) within two scenarios: (1) Current and (2) Future expectations for RSV management. RESULTS/UNASSIGNED:Ninety questionnaires were completed: 70 by respondents (71.4% physicians; 27.1% researchers/scientists) from 16 LMICs and 20 from nine high-income (HI) countries (90.0% physicians; 5.0% researchers/scientists), as a reference group. Within LMICs, RSV awareness was perceived to be low, and management was not prioritised. Of the 100 factors scored, those related to improved diagnosis particularly access to affordable point-of-care diagnostics, disease burden data generation, clinical and general education, prompt access to new interventions, and engagement with policymakers/payers were identified of paramount importance. There was a strong need for clinical education and local data generation in the lowest economies, whereas upper-middle income countries were more closely aligned with HI countries in terms of current RSV service provision. CONCLUSION/UNASSIGNED:Seven key actions for improving RSV prevention and management in LMICs are proposed.

OBJECTIVE: The aim of this study is to compare outpatient respiratory syncytial virus (RSV) immunoprophylaxis (IP) use and relative RSV hospitalization (RSVH) rates for infants <29 weeks' gestational age (wGA) versus term infants before and after the 2014 American Academy of Pediatrics (AAP) policy change. STUDY DESIGN/METHODS: Infants were identified in the MarketScan Commercial and Multi-State Medicaid databases. Outpatient RSV IP receipt and relative <29 wGA/term hospitalization risks in 2012 to 2014 and 2014 to 2016 were assessed using rate ratios and a difference-in-difference model. RESULTS: = 0.2867). CONCLUSION/CONCLUSIONS: The 2014 policy change was associated with a decrease in RSV IP use and an increase in RSVH risk among otherwise healthy infants <29 wGA.
