Nipah virus (NiV): biological principles
Core principles relating to the biology and transmission of Nipah virus.
Documents
Details
The biological principles document represents an expert consensus position and is used for emerging infections where there remains a high degree of uncertainty about the pathogen’s properties. This document was produced for NiV in March 2026 and reflects the working position at that time. This document is not maintained as a live summary of the current evidence and is reviewed annually.
This document outlines the current knowledge and assumptions about the biology and transmission of NiV to be used in developing an evidence-based response to cases of NiV.
