Faulse claimes can easily make their way into the mind of the uninformed. Two years ago Ebola virous broke in Nigeria, some people said it was a terrorist attack by boko-haram(nigerian ISIS) and everyone should have their bath before 6am with salt and some said salt and warm water. As i type this now i smile, remembering how funny it was . Salts quickly disappearing in shops and family members calleling friends and loved one to take a "salt bath" before six am. I remember asking my sister what if one didn't do that before the stipulated time, and you can't imagine the scloding i got from her and my mum..but i eventualy didn't do it because i knew from the start that that was a factless information. Just like you said, if it were to be in the air which still circulates, the pepetrators will also taste their own poisoned hands(my people'saying).
I think yhe best way to deal with this form of missinformation is to neglect it because, the more you talk about, the more it gains ground even if yoi are saying against it.
Nice one kyriacos.
