Virus wiki
Nipah
Nipah virus is a zoonotic paramyxovirus with high case-fatality risk; outbreaks are often linked to bats, pigs, or contaminated food products in South and Southeast Asia.

Important
Virus Tracker provides aggregated outbreak monitoring for education and situational awareness. It is not medical advice, a diagnostic service, or a substitute for guidance from qualified health professionals or official public health agencies. Always consult licensed clinicians and authoritative sources for personal health decisions.
Overview
Nipah virus causes severe encephalitis and respiratory disease. Spillover events remain episodic but carry outsized public concern due to severity and potential for nosocomial amplification. Surveillance integrates animal health, food safety, and rapid isolation protocols. Virus Tracker provides a high-level geographic lens on reported human activity where open datasets exist.
Transmission
Fruit bats (flying foxes) are natural reservoirs. Humans may be infected through consumption of contaminated date palm sap or close contact with infected animals or humans in healthcare settings without adequate infection prevention.
Symptoms & clinical notes
Illness may present as fever, headache, drowsiness, disorientation, and respiratory symptoms; encephalitis can progress rapidly. Early isolation and supportive care are critical.
Prevention & control
Avoid raw sap where outbreaks occur, use personal protective equipment around suspect cases, and strengthen hospital infection control. Community messaging should be culturally tailored and coordinated with veterinary services.
Surveillance context
Event-based surveillance, contact tracing, and laboratory networks anchor response. Cross-sector alerts reduce delay between animal signals and human case detection.

FAQ
Is this page medical advice?
Virus Tracker provides aggregated outbreak monitoring for education and situational awareness. It is not medical advice, a diagnostic service, or a substitute for guidance from qualified health professionals or official public health agencies. Always consult licensed clinicians and authoritative sources for personal health decisions.
What does the pressure index mean on Virus Tracker?
Pressure index reflects active-case burden relative to recoveries in our models. It helps compare stressed outbreak zones within the dataset—it is not a clinical score.
How often is this wiki updated?
Figures refresh on the site’s ingestion and revalidation schedule (typically about every 30 minutes in production). Timestamps on the dashboard snapshot indicate the last build of the underlying dataset.
Why might the heat map not match official government totals?
We merge multiple open sources and fallbacks; reporting lag, testing policy, and geographic coverage differ by country. Use national health ministries for authoritative case definitions.
