The cold, like the flu, is a virus and cannot be treated with antibiotics. Unfortunately, the only true treatment is to wait until has run it's course.
The flu is similar to the common cold but the symptoms are usually much more severe. Five to 20 percent of the American population come down with the flu each year. It can be very serious and even fatal.
The flu is a virus called influenza. It cannot be treated with antibiotics, but may be prevented with a flu shot and new antiviral medications, such as Tamiflu, may help shorten the duration of the flu.
Cold or Flu?
The common cold and the flu are both respiratory illnesses with similar symptoms. So how can you differentiate between the two?
The main difference between the common cold and the flu (influenza) is the severity of the symptoms.
Flu symptoms:
* Come on quickly and severely.
* Include fever, which tend to be higher and last longer (3 to 4 days) than the occasional low-grade fever that may accompany a cold.
* Include body aches and severe tiredness or fatigue.
Common cold symptoms:
* Gradually get worse over a few days.
* Are more likely to include runny or stuffy nose than the flu.
* Often include a sore throat, while flu rarely does.
* May cause tiredness, but it is much less severe than the exhaustion that comes with the flu.
* Do not usually result in serious health problems and hospitalizations.
Tests are also available to diagnose the flu but there are no such tests for colds.
A quick flu test can be done in the doctor's office and the results are usually available within a few minutes. These tests may help your doctor decide whether antiviral medications will benefit you if you do have the flu, but are more often used for the purpose of determining how widespread your flu is. Doctor's can usually decide which course of treatment is best for you based on your symptoms and medical history.
