Current Situation and Global Perspective of Nipah Virus

Area of Science:

• * Infectious Diseases
• * Virology
• * Public Health

Background:

• * Nipah virus (NiV) is a highly pathogenic zoonotic virus identified in 1998.
• * NiV outbreaks have occurred in South and Southeast Asia, with high case fatality rates (40-75%).
• * Geographic concerns and population mobility keep Indonesia on high alert despite no reported cases.

Purpose of the Study:

• * To review the global epidemiological situation of NiV as of 2026.
• * To evaluate public health preparedness for NiV.
• * To analyze ongoing research, including vaccine and therapeutic development.

Main Methods:

• * Literature review of epidemiological data.
• * Assessment of public health surveillance and response strategies.
• * Analysis of current vaccine and therapeutic research.

Main Results:

• * NiV outbreaks are concentrated in Bangladesh and India, primarily bat-to-human transmission through food.
• * Human-to-human transmission is limited.
• * Improved surveillance and rapid response have reduced outbreak sizes.
• * Vaccine candidates are in Phase II clinical trials.

Conclusions:

• * Nipah virus remains a high-consequence emerging pathogen with a low current global pandemic risk.
• * Sustained surveillance, vaccine development, ecological research, and strengthened health systems are critical.
• * Continued vigilance is necessary, especially in regions like Indonesia.
