Unmasking Nipah: Understanding the Virus, Outsmarting the Threat

Résumé

Introduction: The Henipavirus genus includes the zoonotic Nipah virus (NiV), primarily transmitted from fruit bats to humans and other animals, notably pigs. Since its first outbreak in Malaysia in 1999, NiV has led to significant morbidity and mortality in regions like Bangladesh and India. Discussion: NiV exhibits fatality rates as high as 90% in certain outbreaks, causing a spectrum of clinical signs ranging from asymptomatic infections to severe respiratory illnesses and encephalitis. The virus's seasonal epidemiology is often linked to the mating cycles of bat reservoirs and the collection of palm sap, a common transmission method in Bangladesh. Diagnosis relies on serological and molecular techniques, while treatment remains largely supportive, with ribavirin and monoclonal antibodies showing clinical efficacy. Results: Preventive measures focus on reducing human exposure to bats and infected animals, enhancing hygiene practices, and enforcing strict infection control in healthcare settings. Currently, no licensed vaccine exists, highlighting the urgent need for research in vaccine development and antiviral therapies to manage future outbreaks. Conclusion: This review synthesizes current knowledge on NiV epidemiology, pathogenesis, clinical manifestations, and preventive strategies. It emphasizes the necessity for increased awareness and preparedness among health professionals and the public to mitigate the impact of NiV.
