ABSTRACT: In the late 60s, the presence of Japanese encephalitis, the most common arboviral encephalitis in South East Asia, had been documented in Myanmar. Sporadic outbreaks with clinically suspected JE cases have been reported from some parts of Myanmar but only few cases have been confirmed. Acute Encephalitis Syndrome (AES) Surveillance done at the National Health Laboratory, found Rakhine State endemic for JE in 2007 and 2008. From 2009 to 2011, a total of 409 sera samples and 41 CSF samples were tested for JE IgM using Panbio JE/Dengue Combo and X-Cyton JEV Che X (JE IgM) ELISA Kits. In 2009, no JE positive was detected but in 2010, 17 cases were positive from the 216 sera samples. Up to September 2011, 17 out of 156 sera samples and 3 out of 22 CSF samples tested positive for JE IgM antibodies. All positives were confirmed at the WHO Reference Center at the National Institute of Mental Health and Neurological Science (NIMHANS) in Bangalore, India. JE positives were from Yangon, Mandalay, Bago, Magway, Ayeyawady, Taninthayi Regions and Rakhine, Shan, Kayin, Kayah and Mon States, showing a wide geogra-phical range. Was JE already in those areas and diagnosed after heightened awareness or was it due to the climatic and environmental changes, bringing about the surge of vectors and spread of the disease? Will vaccination be needed? These are the questions which need to be answered.
