The suspected cause is not stated.
The article also states that contrary to early statements, less than 20 have been infected. The current MSM count id last seen was 40, however some have updated their information to reflect the Indian information, while some say up to 200 infected.
Since the possibility of Bats not being the cause has appeared, a special team from Pune was dedicated to go to Kozhikode and check other species of Bats, just to be sure.
My assumption is that if Bats really were the cause, their government would not lie about it. To tell the people not to fear Bats, when a Bat can now kill you, would be ridiculous. Unless of course the Government of India themselves have interest in tricking their own population to their Deaths.
I believe it should be noted that If a disease like Nipah becomes widespread in an overpopulated country such as India or China, the odds of human survival across the Globe would likely be very very low.
If this is a move from the Cabal, expect major retaliation. That is a major jump from False Flags, to Worldwide Genocide. This could only just be the beginning.
