I don't know if you noticed this video I posted it might contain something very helpful to help prevent the virus very cheaply and easily. I am going to try this. The video is from a hundred year old lady from the US State of Alabama who was ten years old when the 1918 Spanish Flu hit their tiny little town in the sticks. They were a very devout Christian and I would say holy family, very ,very charitable. They were the only family in the entire town not to get smitten and between them they nursed over 200 residents back to health! Awesome! If they had not done so the entire place might have been wiped out!! But this lady says the reason why she thinks her family escaped the virus was that their mother gave them a half spoonful of Bicarbonate of soda miked up with water each Morning! She said this changed the bodies chemistry to be more Alkaline and stopped the virus dead in its tracks. I am certainly going to try this. So cheap and easy!! Anyway her story is so very,very touching.
