Do not worry about this new flu. It is treatable, and very few people in Ca. have contracted it. It's origin is from Mexico. And although, most unfortunately it has made it's way into different parts of the U.S. still, it is by no means a pandemic.
I always like to remind people, to stay home, if they can, in the event that they are sick. And to wash thoroughly their hands with soap and water. If soap is not available at the time, a very good washing with hot water will work too. And try to stay away from anyone that appears to be hacking up a lung. I do not like to stand too close to anyone either, partly it is a matter of my personal space not being invaded, and partly so I can at least attempt to avoid any one's germs.
