I can understand what you mean as the night the Global Warming e-mails were dumped I was on line and in the heat of it as bloggers and scientists came together in the dead of night. I followed it all as they wanted confirmation...shared what was coming out...etc. I'll never forget it and didn't sleep at all that night.
That's why I am not opposed to bloggers etc. Although some can muddy the waters in a crisis most are very good at attracting people of brillant minds who can filter the false from the real. In a crisis they have little time to give the bogus stuff any mind so those fall off the speed the internet takes in getting the facts out as the information comes in. In no time the sites where the truth of the matter is and dilogue about rises to the top.
Though of course a pandemic is another story altogether as dealing with life matters and something which one can't necessarily see to fight.
You say the HIV virus has already infiltrated every nation and thus many who are carriers. I thought one could be tested for this? I know surgeons who require such a test before they will do surgery.
