This image depicts Dr. James J. Sejvar, Neuroepidemiologist from the Centers for Disease Control and Prevention (CDC), Atlanta, as he was examining an acute encephalitis syndrome (AES) patient, three weeks after being discharged from the hospital on July 5, 2013. An outbreak of AES occurred in Muzaffarpur, Bihar, India, from May to July, 2013. This child presented with post AES left upper limb hemiparesis, leading to the rejection of the a priori belief that AES cases in Bihar are resolved with no remaining sequelae.
During the outbreak, investigators searched for possible environmental exposures associated with the disease, including toxins in the soil, and where the children were playing.
“Acute encephalitis syndrome (AES) is a clinical condition caused by infection with Japanese encephalitis virus (JEV) or other infectious and noninfectious causes. A confirmed etiology is generally not required for the clinical management of AES.”
