If you have symptoms of flu- fever, chills, cough -
even if you've had a flu shot, it's important to get checked
out in two situations.
First, if you're severely ill and having trouble breathing,
and second, if you have an underlying health problem
such as diabetes.
People with those conditions should see a doctor promptly,
because treatment in the first 48 hours can greatly reduce your
chances of becoming severely ill.
