SARS is spooking everyone. There's almost nothing you can do to avoid or prevent it. You have to bank on your body's immune system.

People are now afraid to travel to HK, Singapore, Vietnam and South China. As if the war and the on-going terrorist treat are not bad enough. When I was a kid, dengue fever was the most common epidemic (It still is). Serious cases can cause death. The disease is carried by the Aedes mosquito. Mosquitoes, coughs and sneezes are now harbingers of death.
