Clinical Context Peer-reviewed veterinary literature continues to shape everyday decision-making for production animal practice, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated A study published in BMC infectious diseases in 2026 evaluated developing laboratory indicators to predict the probability of in-hospital progression to severe disease in elderly patients with influenza A virus infection..

Key Findings The progression of respiratory viral infections to severe disease, and the associated high mortality in elderly patients, pose a significant clinical challenge. Currently, effective warning tools specific for predicting severe influenza are lacking. To preliminarily develop a laboratory‑based prediction model using routine clinical laboratory markers to estimate the risk of in-hospital progression…
