As world continues recover from coronavirus disease 2019, World Health Organization identified list of high-priority pathogens with potential cause future pandemics. Among them virus (NiV), poses significant threat. Even small outbreak could trigger widespread panic among public.

Nipah virus (NiV) is one of a group highly pathogenic viruses classified within the Henipavirus genus. Since 2012 at least 11 new henipa-like have been identified, including from locations and reservoir hosts; pathogenicity these has yet to be determined, but two them associated with morbidity, fatalities. The efficacy cross-reactivity vaccine candidates derived soluble glycoproteins both NiV Hendra (HeV) was evaluated in our recently established hamster model. Both preparations resulted strong humoral responses against antigenic targets, demonstrating cross-reactive immunity. Efficacy determined through challenge hamsters Malaysian (NiV-M) strain. 100% survived lethal dose after prime/boost immunisation HeV presence adjuvant, clinical signs pathology being significantly reduced immunised animals. This first time compared NiV-M model Alhydrogel AddaVax, providing evidence that closely related henipavirus species can provide cross-protectivity infection alternate henipaviruses, supporting potential an effective pan-henipavirus for use frontline outbreak response.

Zoonotic viruses have significant pandemic potential, as evidenced by the coronavirus pandemic, which underscores that zoonotic infections historically caused numerous outbreaks and millions of deaths over centuries. induce types illnesses in their natural hosts. These are transmitted to humans via biological vectors, direct contact with infected animals or bites, aerosols. continuously evolve adapt human hosts, resulting devastating consequences. It is very important understand pathogenesis pathways associated viral across various hosts develop countermeasure strategies accordingly. In this review, we briefly discuss advancements diagnostics therapeutics for infections. provides insight into recent outbreaks, dynamics, licensed vaccines, well vaccine candidates progressing clinical investigations. Despite advancements, challenges persist combating due immune evasion, unpredicted complexity responses. Most these lack effective treatments relying entirely on supportive care preventive measures. Exposure animal reservoirs, limited access, insufficient coverage further pose efforts. This review highlights critical need ongoing interdisciplinary research collaboration strengthen preparedness response against emerging infectious threats.

Nipah virus is a high-consequence pathogen that causes sporadic outbreaks with high mortality, and there are currently no vaccines or therapeutics available for Nipah. Vaccine development against faces challenges due to its current epidemiology limited outbreak sizes, which impedes the feasibility of conducting vaccine efficacy trials focused on disease endpoints. We review progress candidates in human clinical highlight evaluating nature outbreaks, given epidemic potential implications pandemic preparedness. examine alternative regulatory pathways, including US FDA's Animal Rule EMA's conditional marketing authorization, permit approval based surrogate markers rather than data from large-scale Phase-3 trials.

Nipah virus (NiV) is a non-segmented negative-strand RNA (nsNSV) with high pandemic potential, as it frequently causes zoonotic outbreaks and can be transmitted from human to human. Its RNA-dependent polymerase (RdRp) complex, consisting of the L P proteins, carries out viral genome replication transcription therefore an attractive drug target. Here, we report cryo-EM structures NiV complex in apo early elongation state incoming substrate bound. The structure enzyme reveals architecture L-P which shows degree similarity other nsNSV complexes.

SUMMARY Henipaviruses were first identified 30 years ago and have since been associated with over outbreaks of disease in humans. Highly pathogenic henipaviruses include Hendra virus (HeV) Nipah (NiV), classified as biosafety level 4 pathogens. In addition, NiV has listed a priority pathogen by the World Health Organization (WHO), Coalition for Epidemic Preparedness Innovations (CEPI), UK Vaccines Research Development Network (UKVN). Here, we re-examine epidemiological, ecological, clinical, pathobiological studies HeV to provide comprehensive guide current knowledge application identify evaluate countermeasures. We also discuss therapeutic vaccine development efforts. Furthermore, case identification, prevention, treatment mind, highlight limitations research recognize gaps necessitating additional studies.
