Encephalitis is a viral infection which causes flu-like symptoms such as high fever, convulsions, headache, vomiting and in extreme cases, brain dysfunction, seizure, and inflammation of heart and kidney.

More than 100 children have now died in an outbreak of suspected acute encephalitis syndrome (AES) in India's Bihar state, officials say.

At least 200 patients, many of whom are below the age of 10, are still being treated at two hospitals. State officials have said that many victims had died due to hypoglycemia, or low blood sugar.

Some of children`s death sue to brain disease believed to be linked to a toxic substance found in lychee fruit, health officials have said. The outbreaks of the disease have happened annually during summer months in Muzaffarpur and neighbouring districts since 1995, typically coinciding with the lychee season.

US researchers had said the brain disease could be linked to a toxic substance found in the exotic fruit. They also said more study was needed to uncover the cause of the illness, which leads to seizures, altered mental state and death.

Outbreaks of neurological illness have also been observed in lychee-growing regions of Bangladesh and Vietnam.

Pay attention to only lychee is not enough if you are traveling world. There are much more diseases which have risk of infection diseases with orally transmitted. We are always open to people who are willing to get advice about the matter!
