Like I said I heard it on the radio then read that post I haven't checked ! but I'm sure if it's true we'll know soon enough....Do you not find it strange considering the length of time they've been researching this thing ,that no Scientist anywhere in the world is any further forward in working this virus out ..They're actually coming up with more question marks than full stops..Can't find it on any official government or nhs twitter account though... strange if their desperate to circulate it on twitter...
