This is what my university is advising students from areas currently affected, which is defined as Hong Kong, Singapore, Taiwan, Inner Mongolia, Ulaanbaatar City (Mongolia), Toronto (Canada) and, in China, the regions of Guangdong, Shanxi, Beijing and Tianjin.
1. If you do not have the SARS symptoms the medical advice is that you are not a risk to others and should continue with your studies, exams and other activities as normal.
2. If you have returned from a SARS affected region it would be helpful if you would inform the University Health Centre. Any information will be treated in confidence.
3. If, within 10 days, of returning from a SARS affected region you feel unwell you should immediately return to your term-time home and phone your doctor for advice. If you are not currently registered with a doctor you should phone the University Health Centre.
A much more apprioriate course of action, in my opinion.
