Hi C.,
I'm glad you asked. My work is dedicated to public health planning for pandemic influenza, and the seasonal flu (regular flu) is transmitted much the same way.
The best way to hamper the spread of most contagious diseases is "in your hands". Most viruses, like the flu, are transmitted by coughs and sneezes. Sometimes, if conditions are right, viruses left on an object by cough or sneeze can be picked up by someone else on their hands. Your a mom and you know how some people - not excluding men ( ;) no offense, dad), but particularly children manage their coughs,sneezes, and mucus (aka boogers).
Here's how you can slow the spread:
1. COVER THOSE COUGHS AND SNEEZES! We need to change some habits though. We've all learned to cover our mouth and nose with our hand. It's best to cover with a tissue. I mean REALLY COVER. Then throw the tissue into the trash, and wash your hands with soap and water scrubbing for 20 seconds before rinsing. If you don't have a tissue handy at the critical moment, cough or sneeze into your sleeve at your elbow. That puts the virus (and other ickyness) away from your hands so you don't leave it behind on objects or people when you touch.
2. STAY AWAY FROM PEOPLE WHO ARE SICK. You're more likely to pick up their "germs", just like Granny told you. In your case, your little one needs to eat. If you have stored milk in the freezer, have Dad or big brother feed that. You can pump and store your milk while your down with the flu. The milk is still good as long as you are very careful about handwashing before you handle the equipment, milk, etc.
3. WASH YOUR HANDS FREQUENTLY THROUGHOUT THE DAY WITH SOAP AND RUNNING WATER. Rub and Scrub for 20 seconds before rinsing. If soap and water are not available, use hand sanitizer gels containing 60% alcohol or more. It's a good substitute, but hand washing is the best.
4. KEEP YOUR HANDS AWAY FROM YOUR FACE. Viruses infect us through our mucus membranes of the eyes, nose and mouth. If your hands are carrying a virus and your rub your eye, eat without washing your hands, or do some unseemly thing with your nose, you can plant the virus exactly where it needs to be in order to grow and infect you.
5. THE WORLD IS FULL OF VIRUSES. Here in "the OC" most grocery stores have those wipes at the door. Use them to wipe down the handle and places you might touch on the grocery cart. It might sound a little like MONK (TV show about a germ-phobic detective), but we know it helps. If you carry handwipes (60% alcohol-by the way, handwipes don't count against your carry-on liquids in the airport, another virus laden place)you can use it in other places where wipes are not provided.
6. GET A FLU SHOT EVERY YEAR!!! I know the biggest myth known to mankind is: you'll get the flu from the shot." LIES-ALL LIES!!! People who come down with the flu after getting the shot had been exposed to the virus the week before getting the shot. In fact, the shot will make the illness less severe than if they hadn't been immunized. This year things got a little different with a strain of human influenza that was not expected, but CDC has things under control for this coming years vaccine. There will be several events in the Fall offering free vaccine. It's also not too late to get your flu shot now, for this year. Keep your eye on the news for coming flu shot events.
Sorry about the long-winded response. I'm glad you're still breastfeeding you little one. That will help build his immunities as well. By the way, chicken soup is still good for the one who has the flu. Good Luck and I hope you feel better soon.
