Three more results are awaited, they added. With timely action, the district authorities managed to effectively contain the spread and limited it to just six positive cases,even when they had identified 1,286 suspects. Since the scare began, 352 samples were sent for testing and with no positive cases in the past five days, authorities have started to breathe easy, even though caution continues at the two places which reported two deaths. On Thursday, there were 952 people under observation and the condition of a nine-year-old boy who was positive has turned much better. The NIV Pune officials are continuing their studies and testing with the bats in the affected two places, but still have not been able to either get a positive result nor have they been able to identify the cause of it.
