Nipah Virus -Infection, Symptoms, Diagnosis & Treatment !

Viruses

Nipah virus (NiV) is a member of the family Paramyxoviridae, genus Henipavirus. NiV was initially isolated and identified in 1999 during an outbreak of encephalitis and respiratory illness among pig farmers and people with close contact with pigs in Malaysia and Singapore. Its name originated from Sungai Nipah, a village in the Malaysian Peninsula where pig farmers became ill with encephalitis. Given the relatedness of NiV to Hendra virus, bat species were quickly singled out for investigation and flying foxes of the genus Pteropus were subsequently identified as the reservoir for NiV (Distribution Map).

In the 1999 outbreak, Nipah virus caused a relatively mild disease in pigs, but nearly 300 human cases with over 100 deaths were reported. In order to stop the outbreak, more than a million pigs were euthanized, causing tremendous trade loss for Malaysia. Since this outbreak, no subsequent cases (in neither swine nor human) have been reported in either Malaysia or Singapore.

The Current State of Diagnostics for Meningitis and Encephalitis

Infections of the central nervous system (CNS) such as meningitis or encephalitis can be caused by myriad microorganisms and may be life-threatening. Patients with acute CNS infections generally present with similar findings of fever, headache, and neurological changes. Given the similarity in symptomology, it is often difficult to distinguish bacterial and viral infection based on clinical presentation alone. As a result, obtaining a rapid and accurate diagnosis is important for proper patient management. Indeed, rapid identification of CNS pathogens is critical for antimicrobial treatment in cases of bacterial or herpes simplex virus (HSV) infection. Any delays in appropriate therapy can lead to poor patient outcomes, including death.

The aim of this Continuing Education article is to review the current landscape for diagnostic testing of cerebrospinal fluid (CSF) in acute CNS infections, present the potential impact of rapid identification, and discuss methods to increase the diagnostic yield in uncertain cases. It is anticipated that new technologies will aid in providing rapid and accurate pathogen identification, potentially leading to better patient outcomes, improved antimicrobial stewardship, and decreased hospital costs.
