Routes of infection for SARS virus, artwork. The SARS virus (spiky balls) causes severe acute respiratory syndrome. It is a coronavirus (as are some common cold viruses), and infects the lungs (purple, in chest) where it causes coughing, sneezing and watering eyes. This spreads the virus in liquid droplets through the air and on hands. It can also be contracted by touching contaminated surfaces or fluids. SARS was first recorded in China in late 2002. The disease can cause death by respiratory failure, and has a mortality rate of around 10%, although this is higher in the elderly.
