First rule, and written clearly on the back cover:DON'T PANIC.
That being said, there is indeed pandemic potential for the Swine Flu. If you're not familiar with this recent development, look here:http://news.yahoo.com/s/ap/20090425/ap_on_re_la_am_ca/med_swine_flu
Swine Flu's first victims were in their 20-40s in age. This is reminiscent of the Spanish Flu, which also killed people indiscriminantly of their age or apparent health. The reason this is the case is that it's a cross-species virus. Human immune systems have no exposure to this virus, so we have little to no species immune history against it.
It's in the U.S., confirmed cases in Kansas, California, New York, and possibly 4 other states. It is spreading human to human, so it has extremely high potential to mutate.
Don't panic. If you get the flu (be it Swine Flu or regular), bite the bullet and don't go to work: go to your doctor. Symptoms include fever, lethargy, lack of appetite, coughing, runny nose, sore throat, nausea, vomiting and diarrhea; in other words, the same symptoms for any other flu.
If it does become a global pandemic and you want to prepare? Well... if a pandemic happens you're probably going to get infected. Vaccines take months to make, so you won't get them in time. So what can you do?
Stay healthy. Wash your hands
. Eat healthy. Moderate aerobic exercise daily (nothing too extreme or damaging). Stay hydrated. Increase your Vitamin C.
