First isolated in 1994, the virus has since been connected to numerous outbreaks of disease in domestic horses and seven human cases. Hendra virus belongs to the genus Henipavirus, which also contains the zoonotic Nipah virus. The reservoir species of Hendra virus are four species of bat within the genus Pteropus native to Australia.
In common with other members of the Paramyxoviridae family, the number of nucleotides in the henipavirus genome is a multiple of six, consistent with what is known as the 'rule of six'. [ 18 ] [ 19 ] Deviation from the rule of six, through mutation or incomplete genome synthesis, leads to inefficient viral replication, probably due to ...
The Nipah virus structural model, constructed at an atomic resolution, depicts a particle with a diameter of 90 nm, adorned with spikes. This model affords a glimpse into the virus's interior. The Nipah virus is known for its high mortality rate and is viewed as a potential candidate for the next pandemic.
Both viruses are contagious, highly virulent, and capable of infecting a number of mammalian species and causing potentially fatal disease. Due to the lack of either a licensed human vaccine (a Hendra virus vaccine exists for horses) or antiviral therapies, Hendra virus and Nipah virus are designated as Biosafety level (BSL) 4 agents. The ...
Nipah virus Nipah is a henipavirus, the most lethal of paramyxoviruses . It was first identified in pigs in Malaysia and Singapore in the late 1980s, though its natural reservoir is fruit bats.
Nipah virus infection is an infection caused by the Nipah virus. Symptoms from infection vary from none to fever , cough, headache, shortness of breath , and confusion. This may worsen into a coma over a day or two, and 50% to 75% of those infected die.
Henipavirus contain an enveloped single-strand negative-sense RNA genome. Therefore, they belong to the same genomic group of viruses such as measles and mumps which are more commonly found to cause pathogenesis and infection in humans; Measles, mumps, and other related viral pathogens also belong to the viral family Paramyxoviridae.
Langya henipavirus (LayV), also known as Langya virus, is a species of henipavirus first detected in the Chinese provinces of Shandong and Henan. [ 1 ] [ 2 ] [ 3 ] It has been announced in 35 patients from 2018 to August 2022.
