Transmission: Nipah virus primarily spreads through direct contact with infected animals, particularly fruit bats (Pteropus genus). Humans can transmit, via close contact with one another, infected individuals’ respiratory secretions or bodily fluids.
Outbreaks: Since its discovery, the Nipah virus has been associated with several outbreaks in South and Southeast Asia. Outbreaks have occurred in Bangladesh, India, Malaysia, and Singapore. These outbreaks have mainly been localized, with sporadic or small clusters of cases reported.
Seasonality: In certain regions, Nipah virus outbreaks have shown seasonal patterns. In Bangladesh and India, for example, outbreaks have been linked to the consumption of date palm sap, which gets contaminated with bat urine or saliva during the winter months when bats feed on the sap.
Case Fatality Rate: The case fatality rate of Nipah virus infection can vary. It was said to be more than 40-75% in some outbreaks. The severity of the disease can be as low as respiratory symptoms to severe encephalitis.
Hosts: Fruit bats, also known as flying foxes, are considered the natural reservoir hosts of the Nipah virus. Intermediate hosts, such as pigs, can amplify the virus and facilitate transmission to humans. In some outbreaks, human-to-human transmission has occurred without the involvement of intermediate hosts.
Occupational Risk: Landowners, veterinarians, and individuals dealing closely with animals such as pigs or bats are at a higher risk of infection by Nipah.
When an outbreak occurred, it was first identified in Malaysia in 1998 and is known in humans; it can induce severe respiratory disease and encephalitis And other animals.
The Nipah virus is classified as follows:
Domain: Riboviria
Kingdom: Orthornavirae
Phylum: Negarnaviricota
Class: Monjiviricetes
Order: Mononegavirales
Family: Paramyxoviridae
Subfamily: Paramyxovirinae
Genus: Henipavirus
Species: Nipah henipavirus
The Nipah virus has a unique structure consisting of a lipid envelope surrounding a helical nucleocapsid. The membrane for host cells is the source of this envelope and contains viral glycoproteins on its surface.
The viral genome of the Nipah virus is a single-stranded negative-sense RNA molecule. It is approximately 18,234 nucleotides long and encodes for several viral proteins required for replication and virulence.
The viral glycoproteins on the surface of the Nipah virus play a crucial role in attachment and entry into host cells. The two main glycoproteins are the fusion (F) protein and the attachment (G) protein. These proteins facilitate the fusion of the viral envelope with the host cell membrane, allowing the virus to enter the cell.
Inside the host cell, the Nipah virus replicates its RNA genome and produces viral proteins, which assemble to form new virus particles. The infected cell releases the newly formed viruses, spreading the infection to other cells and tissues in the host organism.
The Nipah virus is a transmissible virus related to Henipavirus and Hendra virus. The Nipah virus G glycoprotein is a critical antigenic protein that facilitates viral attachment to host cell receptors. The G glycoprotein head region in monkey models is highly antigenic, eliciting head-specific antibodies. One head-specific antibody, m102.4, has finished Phase 1 clinical studies and has been utilized under compassionate use circumstances.
Based on phylogenetic analyses of the N & G gene sequences, the Nipah virus is divided into two main clades: the NiV-MY clade & the NiV-BD clade. Isolates from Malaysia & Cambodia belong to the NiV-MY clade, while isolates from India and Bangladesh belong to the NiV-BD clade. Thailand NiV isolates exhibit a heterogeneous population of sequences.
T-cell epitopes that are part of Nipah virus pathogenic proteins, notably the G glycoprotein, have been discovered and modeled in several investigations. These epitopes can trigger CD4+ or CD8+ T cells to react & may be helpful in the development of vaccines or immunotherapy. In the NiV-G protein, for example, one research discovered an H2-b-restricted nonameric peptides epitope having CD8+ T cell antigenic properties and an H2-b 15mer with a CD4+ T cell antigenicity.
Nipah is a zoonotic virus that may cause severe sickness and death in humans and animals. The pathogenesis of Nipah virus infection involves the following steps:
The virus enters the host through direct contact with infected animals or their secretions or by consuming contaminated food, such as raw date palm juice.
The respiratory tract’s epithelial cells are infected by the virus, especially in the bronchioles and alveoli, and replicate rapidly.
The virus spreads to other organs, such as the kidneys, spleen, liver, and brain, through the bloodstream and lymphatic system.
The virus causes widespread vasculitis, a key event in the pathogenesis of Nipah virus infection, which leads to vascular leakage, edema, hemorrhage, and necrosis of various tissues.
The virus infects the endothelial and smooth muscle cells of the blood vessels and the central nervous system neurons & glial cells (CNS).
The virus induces inflammatory cytokines and chemokines, which attract immune cells and cause further tissue damage and immune dysregulation.
The virus causes severe respiratory illness and fatal encephalitis in humans, characterized by fever, headache, cough, sore throat, difficulty breathing, vomiting, dizziness, drowsiness, altered consciousness, neurological signs, seizures, and coma.
The predicted case fatality rate for Nipah viral infection is 40% to 75%, depending on the outbreak and the clinical management. Some survivors may have long-term neurological sequelae or latent infections.
To trigger IFN responses, Nipah virus chromosomal RNA is recognized by intracellular cytoplasmic RNA helicases. There is a balance between the cell’s ability to trigger its natural immune system to defend itself and the virus’s ability to antagonize it upon identification. In vitro, the endothelial cells (an essential cell type addressed in vivo) infected by the Nipah virus release IFNβ as well as intrinsic chemokines & cytokines particularly IP-10 & IL-6, respectively.
IP-10 is a ligand that attracts activated T cells, while IL-6 is a cytokine that promotes acute-phase proteins and functions as an inflammation molecule. Not unexpectedly, in vitro migration experiments showed that these chemokines can functionally attract T cells.
The capacity of RNA-based viruses that trigger illness in humans to antagonize the immune system’s natural response appears to be widespread. The Nipah virus is being extensively studied in vitro as its capacity to subvert natural immunity through a variety of mechanisms. The Nipah virus P gene is transcriptionally modified to generate not just the phosphoprotein but additionally two alternate V and also W proteins, with an alternative ORF producing a C protein.
In humans, Nipah virus infection causes a range of clinical manifestations, from asymptomatic subclinical to acute respiratory infection and fatal encephalitis, according to the World Health Organization. A mortality rate of 40% to 75% is estimated for cases. This rate varies based on the epidemic and local conditions, epidemiological surveillance, and clinical management capabilities. Nipah virus infections are:
Fever
Headache
Cough
Sore throat
Difficulty breathing
Vomiting
Dizziness
Drowsiness
Altered consciousness.
Neurological signs that indicate acute encephalitis
Seizures
Coma
The symptoms typically appear in 4-14 days following exposure to the virus. If symptoms like dizziness, disorientation, and confusion are present, which can quickly occur in a coma within 24-48 hours, a phase of brain swelling called encephalitis may develop.
The diagnostic process:
Clinical Evaluation: A healthcare professional will assess the patient’s symptoms, medical history, and potential exposure to Nipah virus risk factors. Common symptoms of Nipah virus infection include fever, headache, muscle pain, respiratory distress, and encephalitis (brain inflammation).
Laboratory Tests: a. Blood Tests: Blood samples are collected to detect the presence of Nipah virus-specific antibodies or genetic material (RNA) using laboratory techniques like polymerase chain reaction (PCR) or enzyme-linked immunosorbent assay (ELISA). b. CSF Analysis: If neurological symptoms exist, a lumbar puncture may be performed to obtain cerebrospinal fluid (CSF) for analysis. CSF testing can help identify Nipah virus RNA or specific antibodies. c. Tissue Biopsy: Postmortem tissue samples may be collected to examine and confirm Nipah virus infection in severe cases or fatal outcomes.
Epidemiological Investigation: Public health authorities conduct investigations to identify the source of the Nipah virus outbreak and determine potential contacts and exposures. It involves interviewing patients and gathering information about their recent travel history, animal contact, or exposure to contaminated environments.
Avoid contact with infected animals: Nipah virus is primarily transmitted to humans through direct contact with infected animals, particularly fruit bats (also known as flying foxes). Avoid handling sick or dead animals, and do not consume fruits or other food items partially eaten by bats or other animals.
Practice good personal hygiene: Maintaining proper hygiene is crucial in preventing the transmission of the Nipah virus. Wash your hands frequently, especially after encountering animals, animal products, or contaminated surfaces. If neither water nor soap is accessible, a hand sanitizer made with alcohol should be used.
Implement infection control measures: In healthcare settings, it is essential to follow strict infection control protocols to prevent the spread of the Nipah virus. It includes using personal protective equipment (such as gloves, masks, and gowns) when caring for infected patients, practicing proper waste disposal, and maintaining a clean environment.
Increase awareness & educate others: Increasing awareness of the Nipah virus and its prevention methods is essential in controlling its spread. Educate yourself and others about the virus, its symptoms, and preventive measures. Encourage your community to adopt safe practices and promptly report any suspected cases to health authorities.
