If there is another outbreak of sars, how can I protect myself?  

Stay away . Sars is a virus which is spread by coughing or sneezing. If we have another outbreak stay away from infected people. Wash your hands frequently too. Infected people are likely to be quarintined.
Healthy lifestyle. Lead a healthy lifestyle - avoid anything that may compromise your immune system - smoking, excessive drinking, maintain good exercise routine and weight. If there is such an outbreak, you will need to exercise standard precautions - frequent handwashing, avoiding congested areas or those areas where incidence of it is high. Wearing a mask may not be a bad idea either.
