Abstract : Emerging as a WHO priority pathogen, Nipah virus (NiV) – an RNA virus within the Paramyxoviridae family – first ignited outbreaks in 1998 Malaysia. Closely related to Hendra virus, NiV continues to threaten South and Southeast Asia. A zoonotic threat, Nipah virus (NiV) jumps from its natural reservoir, fruit bats, to pigs and then humans. This BSL-4 threat, with no cure or shield, compels us to harmonise the voices of humans, animals, and the environment in a One Health symphony to prevent future outbreaks. A 2018 Chinese study identified populations at high risk for Nipah virus infection are Fruit farmers, traders, palm wine brewers, Cattle herders, especially pig farmers and Tourists. Nipah virus exhibits remarkable zoonotic versatility, with transmission pathways between humans and animals varying based on geography. Factors such as diverse livestock breeding practices, local eating habits, and the interplay with the natural reservoir - fruit bats - contribute to this fascinating mosaic of infection routes. Unravelling these complexities is crucial for designing effective control strategies tailored to specific regions. Following exposure to the Nipah virus (NiV), symptoms typically appear within two weeks, ranging from 4 days to 2 months. Fever, headache, dizziness, and vomiting are common initial signs, potentially progressing to severe encephalitis. A promising development in the fight against Nipah virus emerges as the National Institute of Allergy and Infectious Diseases (NIAID) initiates an early-phase clinical trial for an investigational vaccine.
