Japanese encephalitis virus: a review on emerging diagnostic techniques.

Japanese Encephalitis Virus (JEV) is the most common Flavivirus based mosquito borne viral encephalitis in the world, especially in countries of South-East Asia. The conventional methods such as Enzyme-Linked Immunosorbent Assays (ELISA), Reverse Transcriptase Polymerase Chain Reaction (RT-PCR), Plaque Reduction Neutralization Test and virus isolation are still in use today but new advances are being made to develop more efficient, inexpensive, quicker, sensitive and time-saving techniques to detect JEV. Some of these include the use of immunosensors, both lateral flow based assays and electrochemical, as well as the incorporation of nanotechnology into biosensors to develop highly sensitive detection tools. This review focuses on the recent advances that have been made to diagnose Japanese Encephalitis Virus which are critical in breaking the link to zoonotic transmission into the human population where humans are dead-end hosts.
