Besides a flu shot and good old fashioned hand washing, you can take other steps to kill a flu bug before it bites. Taking medicine before you even get symptoms may stop you from getting sick.
ER physician, Dr. Michael Iversen, said, "If you know the flu is in your household or if it's around you, you can catch your symptoms before they come around. You can take some medications, like Tamiflu, to prevent you from getting it."
Hand washing is probably the best and easiest way to avoid the flu or any other virus. If you can't do that, you can always sanitize. Coughing and sneezing into a tissue is yet another simple way to stop the spread of germs.
Dr. Iversen said, "A lot of times, [people who have just gotten over the flu] get maybe another virus or they may get a secondary infection; so, you don't typically get the same infection two or three times in a row. Your immune system will develop a resistance towards that."
Don't believe that old wives tale...rainy weather will not make you sick. Viruses are spread from person to person. That happens more often this time of year, because people spend more time together indoors.
