lasted 12 days after 3 day incubation. caught it visiting friend in hospital. it was a stitched together man-made item that featured 48 hour progressive compartments of different flu examples. that is, every 48 hours a different strain would manifest. One had runny stools. another had pneumonia pain in chest, etc.
do not trust me. ask people who are sick with this if this is the progression they are experiencing.
that will confirm.
