Although the Swine Flu has not sickened anywhere near the number of people that the plain old Flu does each year, it has captured the attention of the media like wildfire.
There are common sense things that we all should do each and every day to protect our health. The first thing is to keep our hands clean. Either wash your hands or use an alcohol based hand cleaner and do it often. Try to form a habit of not touching your mouth or your nose with your hands.
When you go to the grocery store, use those sanitizing wipes on your cart. The last person to use it could have had the flu. When you bring your groceries home, clean your hands again and wash your produce and meat before you use them.
If you do get sick try to stay at home if you can. If you need medical attention be sure to keep your mouth and nose covered with tissue or surgical mask when around others.
There are supplements that can boost your immunity and help you to fight off viruses to which you are exposed. Having a good healthy immune system will help you tremendously.
To summarize, just practice good hygiene like you should do anyway and remember to protect your health with good nutrition. Getting Vitamin D from sunshine or supplements is one way to boost your immunity. Check with your doctor to see what else you should be doing.
