Japanese encephalitis is transmitted to pigs as rapidly in Cambodian peri-urban areas as rural areas

Japanese encephalitis (JE) virus, which causes acute encephalitis in Eastern and Southern Asia, is traditionally considered a rural disease. Now, researchers have shown that pigs in a peri-urban and a rural farm were infected by the virus at the same rate. This finding suggests vaccination efforts should be widened to encourage travelers to receive JE virus immunization.
