I'm not sure that they have identified Japanese encephalitis virus as the 'mysterious disease' that Rohan had talked about in India. The Uttar Pradesh Chief Secretary called a major meeting to come up with preventative and control measures for the disease. It has already killed 400 people and has caused over 1200 cases from this state in the past year. With a population as large as India's, you can imagine how fast it might spread! It will be interesting to watch this unfold.
