Sars: A test of limits to medical expertise Dr Maurice McKeown "Researchers now believe that the corona virus, acting alone, is capable of the severe symptoms seen in some patients. The involvement of other viruses and bacteria cannot be completely ruled out, however. Two other viruses, both paramyxoviruses, seem to be associated with the disease. One of these is a metapneumovirus -- a subclass of the paramyxoviruses. Some researchers believe that these viruses may play a crucial role in some severe cases of the disease. Their reasonable idea is that if they are also present at the same time as the coronavirus they could account for the devastating course which the disease takes in about 20 per cent of those afflicted. Chinese scientists believe that an unusual airborne variety of the bacteria chlamydia, generally known as a sexual transmitted disease, may also be involved. ..... If you have been monitoring the spread of SARS on it’s rapid world transit you might just have wondered, as I did, why it does not appear to have infected Japan or Korea to any significant extent. A Taiwan doctor, Lee Chi Wei, has a hypothesis. He thinks that in the Hong Kong tower block where there has been a spread of the virus without any known congregation of people, there must be a route of transmission other than airborne particles. He suggests that perhaps the route could be via particles left on solid surfaces such as stair rails, lift doors, and even floors and carpets. The coronavirus is probably able to survive for hours on such surfaces. He suggests that more than 90 per cent of people living in Korea and Japan take off their street shoes before entering their apartments, while those in China, Hong Kong and Singapore wear their street shoes into their apartments.
