You can take all the precautions in the world, but sometimes the flu sneaks around your defenses. So what do you do when someone in your house has the flu -- or even swine flu?
To give you an idea, here's a countdown of five average days with the flu. Keep in mind that this rundown is based on a typical case of seasonal flu. There's still a lot we don't know about swine flu. But so far, its symptoms seem to be pretty similar to those of common seasonal flu viruses.
Isn't the 2009 H1N1 swine flu vaccine too new to trust?

Is the 2009 H1N1 swine flu vaccine safe?
No vaccine is 100% safe for everyone. People with allergies to eggs, for example, can't take flu vaccines
because eggs are involved in the manufacturing process.
And flu vaccines cause mild but common reactions. About one in three people
get a sore arm from the shot, some with a little redness or even swelling. Some
10% to 15% of people feel tired or get a headache; some may even run a low fever.
And vaccines can trigger rare but serious reactions, even among people with
no apparent allergies or sensitivities.
So if vaccines aren't 100% safe, why risk them?
Approved vaccines -- including the 2009 H1N1 swine flu vaccine -- are
calculated to be much, much less risky than the diseases they prevent. For
example, out of every million people who get a flu shot, one or two will get a
serious neurological reaction called Guillain-Barre syndrome (GBS).
But flu itself causes serious problems, including GBS, in far more than two
in a million cases. And since a large proportion of the population will get
swine flu, the vaccine risk is far smaller than the disease risk.
In clinical trials, 10,000 to 15,000 children and adults have received
various manufacturers' brands of H1N1 swine flu vaccine. Nothing serious
happened to any of them, including this reporter, who received a double dose of
the Sanofi-Pasteur swine flu vaccine.
