I heard possible reports last night that scientists from Cardiff University have suggested that the SARS virus may have originated from space (https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fsmilies.networkessence.net%2Fs%2Fcontrib%2Fedoom%2Fvery_first_smiley.gif&hash=e4a38a91893cfb0aaece01ea57024bf6) , possibly from a comet/meteor fragment? Ideas?

Interesting it's an issue to consider, then this will mean that there are other living organism in outer space maybe something more than viruses.
I would thought that the SARS virus is mutated form of the common flu. Because people now go and see doctor when ever they have a little cold, bacteria and virus start to get immune to the drugs. The constantly mutating antigen is the result this.
Just a theory.

SARS is definitely NOT a mutated form of 'flu.
See the sticky topic folder at the top of this forum for links to the latest SARS news. It is actually a variant of the virus reponsible for the common cold !

Just heard on the news that they think SARS originates from the sivit (spelling?) cat(https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2F66.227.101.70%2Fotn%2Fanimals%2Fnibble6.gif&hash=ce7c6c8a697edb74d2e1d76f209f5b76), which is a delicacy in China.
Influenza comes from migratory birds. Their droppings fall (https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fsmilies.crowd9.com%2Fgames%2Fff%2Fff4%2Fff4creature%2Fcockatrice.gif&hash=7b6c13b65488dda44b50e5c4022afdb6) where domestic birds can pick up the virus and pass it on to other farm animals(https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2F216.40.249.192%2Fs%2Fotn%2Fanimals%2Foink.gif&hash=da5188e4c4dc09b54a721d76cdc56a73), who pass it on to farmers who pass it on to us.
See, we are all connected! (https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2F216.40.249.192%2Fs%2Fotn%2Fanimals%2Ffrog2.gif&hash=e0531221957881044271b9a7dc521f56) Charming thought.

But the changing flag sort of reflect on how you change your countries every 1 or 2 weeks though.
Not that I want it back on.

Yesterday, the BBC programme, 'Horizon', was talking about SARS. any body seen that? I think it's quite good.

I found this interesting update on SARS diagnosis :
BRITISH JOURNAL OF OPHTHALMOLOGY
[The severe acute respiratory syndrome coronavirus in tears Br J Ophthalmol 2004; 88: 861-3]
SARS, the highly infectious respiratory virus, has been found in tears, reveals a small study in the British Journal of Ophthalmology.
The finding suggests that tear analysis could not only be an effective means of diagnosing the infection, but also an unrecognised source of its spread, if appropriate preventive measures are not taken, say the authors.
Tear samples were swabbed from the tear ducts of 36 patients in Singapore with suspected SARS over 12 days in April 2003. Most of those thought to have the infection were healthcare workers, including nurses.
Eight of these patients subsequently turned out to have probable SARS.
Chemical analysis confirmed the presence of the infection in three of these patients; in one, the virus was found only in the tears. These patients had only recently become infected - they were tested within 9 days of the start of symptoms.
The other five patients had no discernible evidence of the virus in their tear samples. But their symptoms had started over 11 days earlier, suggesting that the tear duct sampling may be a sensitive test for early stage infection, say the authors.
If the infection is caught early, this could make treatment (and isolation) more effective, they say. But the presence of the virus in tears poses a hazard for healthcare professionals caring for these patients.
It is not unusual for viral particles to be present in the eye, say the researchers. Herpes viruses, chicken pox, Epstein Barr virus, hepatitis C and B, and measles have all been detected in tears. But these are the first reported cases of SARS in tear duct fluid, they say.
