Integrated Risk Matrix and Borda Count Analysis on Importation Risk Assessment of Nipah Virus Infection - China, 1999-2026.

Abstract

What is already known about this topic?: Nipah virus (NiV) is a highly lethal zoonotic pathogen. Its re-emergence in India in early 2026 has heightened global public health concerns.

What is added by this report?: This study systematically assessed the risk of NiV importation into China from five affected countries. India and Bangladesh posed moderate importation risks, whereas Malaysia, the Philippines, and Singapore presented low risks.

What are the implications for public health practice?: The findings emphasize that coupling existing defenses with sustained multi-source surveillance and dynamic risk modeling is essential to mitigate risks of stochastic NiV entry.
