It's astonishing: almost every state in the nation has reported widespread flu activity -- 47 states in all, according to the CDC's latest numbers.
Two more children have died since last week's report, raising the total to 20 kids who have succumbed to the virus. Doctors say this strain is worse than last year's.
In New York and other big cities, transit agents are warning passengers to wash hands, cover coughs, and get vaccinated. In Chicago, daycare centers are encouraging kids to keep extra clean.
But that's not enough. While vaccinations are vital for preventing the spread of the disease, Americans have a lot of questions:
Q: Is there enough flu vaccine available?
A: The CDC says, "yes," though some doctors may have to order more. Call ahead to your healthcare provider. Even if you never had the flu, get vaccinated to protect those at high risk.
Q: Can I get the flu if I've already had my shot?
A: Yes. But this vaccine is a good match for this year's most aggressive strain of virus; you can still get sick, but it likely won't be as bad. Experts agree the vaccine is still the most effective way to prevent the illness.
