Importance: During the 2023-2024 respiratory syncytial virus (RSV) season in the United States, 2 new RSV prevention products were recommended to protect infants in their first RSV season: nirsevimab and Pfizer's maternal RSV vaccine. Postlicensure studies are needed to assess prevention product impact and effectiveness.
Objective: To compare the epidemiology and disease burden of medically attended RSV-associated acute respiratory illness (ARI) among children younger than 5 years during the 2023-2024 RSV season with 3 prepandemic RSV seasons (2017-2020), estimate nirsevimab effectiveness against medically attended RSV-associated ARI, and compare nirsevimab binding site mutations among circulating RSV in infants with and without nirsevimab receipt.
In forest ecosystems, the interplay among plant-driven processes and anthropogenic activities profoundly influences water balance dynamics. Hydraulic redistribution is one plant-driven process that can provide a large proportion of a plant's daily water. However, critical gaps exist in our knowledge of hydraulic redistribution including how forest management processes, like thinning, and site-specific factors like basal area and hillslope position, may affect it.
