Does anyone know where I can find out what the actual STAGES for the flu are? Specifically when they turn fatal, and what happens in the body in those different stages from mild to fatal? I had found and bookmarked a site before that listed these things, but it's disappeared. I only remember that at whatever stages, it listed what was happening in the lungs, whether the person experienced delirium or not, if/when they experienced seizures, etc. Can anyone help? I have a story that's really itching to be written, but I can't do so until I have this information. I've looked through all kinds of websites with different sorts of search phrases, but all I can find are sites that only tell the very basic 'fever, chills, achy joints and muscles, and it lasts this long' don't-want-to-scare-the-public sort of info. Thanks ahead of time to anyone who can offer any help!
