Nipah and Hendra virus infectious diseases

Area of Science:

• Virology
• Zoonotic Diseases
• Public Health

Background:

• Nipah virus and Hendra virus emerged in the 1990s, causing high-mortality epidemics in Australia and Southeast Asia.
• These viruses belong to the genus Henipavirus within the Paramyxoviridae family, exhibiting unique characteristics.
• Henipaviruses are zoonotic, with broad tropism, leading to severe respiratory illness and encephalitis.

Purpose of the Study:

• To review the emergence patterns of henipaviruses.
• To summarize reservoir hosts and associated pathology.
• To present recent advancements in henipavirus vaccines and antiviral therapies.

Main Methods:

• Literature review of scientific publications on henipaviruses.
• Analysis of epidemiological data on henipavirus outbreaks.
• Synthesis of research findings on henipavirus vaccines and antivirals.

Main Results:

• Henipaviruses have repeatedly emerged since the 1990s in Australia and Southeast Asia.
• These viruses possess high virulence and a wide host range, necessitating Biosecurity Level 4 containment.
• Significant progress has been made in developing vaccines and antiviral treatments.

Conclusions:

• Henipaviruses represent a significant zoonotic threat requiring ongoing surveillance and research.
• Understanding emergence patterns and pathology is crucial for control strategies.
• Advancements in vaccines and antivirals offer promising therapeutic options against henipavirus infections.
