The problem with the flue is that it regularly mutates. There is a "antigenic drift" every 2-3 years which causes epimia. Every 10-40 years there are bigger changes, "antigenic shift", caused by reassortment betweent other species, which cause pandemia with millions of dead. There were 4 Pandemia in the 20th century.
- already mentioned was the spanish pandemia (H1N1 virus) which caused 20 mio dead
- 1957 Asia pandemia (H2N2) and 1968 Hongkong pandemia (H3N2)
- 1977 Russian pandemia (H1N1)
1997 totally new subtype of Influenza A Virus appeared in the Hongkong epipemia
ther is no cure against viruses
... not true - there are a couple of antiviral treatements out there which work against certain types of Influenza when applied within the first 24-48 hours. (e.g. Neuraminidase inhibitors, Amantadin and Rimantadin)

SARS has not been specified yet but we will hear about it as ssoon as they know more - by chance this week since we'll have lecture with a leading infectionologist in Switzerland.
Personally I think there is no reason to panic... but people like those big catastrophes on tv - while obesity, smoking and traffic kills millions in the meanwhile...
scary it is
Some things that were in the media and here on the boards scare me a thousand times more than any disease!!!
