“…We showed a peak in November–December in Group B (post-pandemic), while in Group A (pre-pandemic), the peak was reached in January–February. This confirms new epidemiological trends of HRSV infection as reported worldwide [ 18 , 24 , 25 , 26 , 27 ].…”

The SARS-CoV-2 Pandemic affected the global epidemiology of respiratory infections, including Human Respiratory Syncytial Virus (HRSV), thanks to state governments’ implementation of mitigation strategies, like the promotion of face masks and lockdowns. However, after the Pandemic, the dramatic resurge of these diseases was reported worldwide. Our retrospective study, involving three Spoke Pediatric Departments, includes all the infants under one year of age hospitalized for HRSV bronchiolitis in a period before the Pandemic period (2017–2020), during the SARS-CoV-2 Pandemic (2020–2021), and after the Pandemic (2021–2023). The primary aim was to analyze the temporal trend of HRSV in these three periods. Then, the clinical and epidemiological characteristics were analyzed to highlight the clinical differences in the affected patients, in the severity of the infections, and in the short-term outcomes. Ultimately, we analyzed the HRSV prevalence in the global bronchiolitis hospitalization over the reported periods. Overall, we included 237 patients. Before the Pandemic, the peak was recorded in January and February, while after the Pandemic, the peak was in November and December. A higher prevalence of HRSV was demonstrated after the Pandemic compared to the period before the Pandemic; overall, no difference in severity was reported. In conclusion, an increase in HRSV cases after the Pandemic has been demonstrated with an anticipated peak, while no differences were recorded in severity.

“…Lachassinne et al [ 87 ] also found in their seroprevalence studies in French day care centres that the share of SARS-CoV-2 infections in young children was low. However, recent studies have shown that the continuation of the epidemic with new SARS-CoV-2 variants and shifts in preventive measures and vaccination changed the situation [ [88] , [89] , [90] , [91] ]. In addition, it seems that transmission between family members seemed more important than transmission within day care centres [ 87 , 92 ].…”

“…9 The increase in severity of illness could also be due to a greater virulence of circulating RSV. 10 Cord RSV IgG antibody level is related with disease severity in the first six months. 11 Decreased encounters of pregnant women with RSV due to COVID-19 appropriate behavior may have resulted in an inherently less passive immunity against the virus in their newborns leaving them susceptible to potentially severe RSV illness.…”

Objective Neonatal bronchiolitis is not well characterized. We studied the profile of acute bronchiolitis in term newborns during a respiratory syncytial virus (RSV) surge following relaxation in coronavirus disease 2019 (COVID-19) appropriate behavior. Methods This was a retrospective descriptive study performed in the neonatology division of a tertiary care pediatric hospital at Srinagar, Jammu and Kashmir, India. Term neonates (born at ≥37 completed gestational weeks) from 7 up to 28 days of life admitted with bronchiolitis over a 1-month period (November 2021) were included. Results Out of total 480 neonatal admissions over a month, 35 (7%) had acute bronchiolitis. Eight neonates were excluded. Out of 27 included neonates, 13 were males. Mean age at presentation was 20 days. All neonates were born at term (≥37 completed gestational weeks). Cough (26), rapid breathing (20), and lower chest indrawing (20) were the predominant presenting features. Median SPO2 was 87% (interquartile range 85–92%). Fourteen (52%) neonates needed admission to neonatal intensive care unit. Respiratory support was needed in the form of oxygen through nasal prongs in 24 (89%) newborns. Heated humidified high-flow nasal cannula (HHHFNC) and bubble continuous positive airway pressure were used in five neonates each. Two neonates were mechanically ventilated. The mean duration of the hospital stay was 6.2 days. All neonates survived. Conclusion A series of 27 term neonates with bronchiolitis during an RSV surge is reported in the aftermath of lifting of COVID-19 restrictions. Many of these neonates were sick enough to require significant respiratory support. The outcome was good in all neonates.
