This image depicts Dr. Parvez Pathan, an Epidemic Intelligence Service (EIS) officer, in the process of collecting environmental information from a case of acute encephalitis syndrome (AES) after this female patient had been discharged from the hospital on June 15, 2013. An outbreak of AES occurred in Muzaffarpur, Bihar, India from May to July, 2013. During the investigation, EIS officers visited 101 case houses, and 101 community control houses for this type of data collection.
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.”
