Confused about swine flu? Even the name of this flu can be puzzling. Usually called swine flu, you'll also hear it called 2009 H1N1 flu and novel influenza A (H1N1). No wonder we're all a little baffled.
But swine flu isn't that hard to understand; it's a lot like seasonal flu. It has similar symptoms, such as fever, cough, sore throat, stuffy nose, body aches, headache, chills, and fatigue. As a matter of fact, it's hard to tell swine flu from seasonal flu without a lab test.

You usually don't get a fever with a cold. If you do, it may be a sign you've got the flu or an infection with a bacteria.
For the first few days that you're sick, your runny nose will be watery, but it turns thicker and darker after that. You may also get a mild cough that can last into the second week of your cold.
Since a cold can make your asthma worse, check with your doctor to see if you need to change your regular treatment plan.
If you cough up thick or dark mucus or you get a fever, you may have an infection with a bacteria. See your doctor to find out how to treat it. Also see him if your cough doesn't get better after a few weeks.
Your symptoms usually start between 1 and 3 days after you get infected with a cold virus. They typically last for about 3 to 7 days. By then the worst is over, but you may feel stuffed up for a week or more.
You're most contagious during the first 3 days that you're sick, but it's still possible to spread it during the first week.
Is It Allergies Instead of a Cold?
Sometimes you might mistake cold symptoms for hay fever. If they begin quickly and are over in 1 to 2 weeks, chances are it's not an allergy.
Allergies are caused by an overactive immune system, your defense against germs. Your body overreacts to things like dust or pollen. It then releases chemicals like histamine. This causes the passageways in your nose to swell, leading to a runny nose, coughing, and sneezing.
Hay fever isn't contagious, but some people may inherit a tendency to get it.
