Japanese encephalitis is a viral disease affecting humans, mostly the children and is a major concern to public health. The single stranded flavivirus is mainly transmitted by mosquitoes of the Culex genus and causes neurological disorders with high fatality. The virus is well amplified in animals like pigs (swine) that act as a host. Close proximity of the domesticated pigs to human settlements increases the risk of human infection. The animal to human zoonoses of this antigen is occured through the mosquitoes bite. Recent developments have led to discovery of various vaccines for the treatment of the disease. This review discusses various aspects of the Japanese encephalitis disease with their transmission, pathogenesis and diagnostic strategies. Moreover it highlights the importance of prevention of transmission of the disease over its cure by proposing a hypothetical kit design model to detect presence of the Japanese encephalitis antigen in the swine populations. This detection process may help to detect infected animals and thus help to keep such animals away from the human settlements so as to prevent transmission as well as outbreak of the disease. This may further help to create a disease free environment, thus saving many lives.
