This cold and flu season could star a cornucopia of viruses. Doctors say they worry the two flu strains (H1N1 and seasonal) could combine, further complicating the situation. Mix in colds, which are prevalent this time of year, and the immune system of Americans could be dealt a one-two punch.

So, how can someone tell if those sniffles they're having is something to be concerned about?

Infectious disease experts say people need to be aware of the symptoms. Dr. Shmuel Shoham, an infectious-disease specialist at Washington Hospital Center, says the common cold, seasonal flu and H1N1 are all respiratory illnesses, but they're caused by different viruses.

Symptoms of the cold are more common, and can make the patient miserable for three to five days. A patient usually has a stuffy nose, congestion, some body aches and a growing cough.

According to the CDC seasonal flu and H1N1 symptoms consist of fever, more painful body aches, dry cough, diarrhea and severe fatigue. It's hard, without testing, to tell apart the seasonal strain of flu from the H1N1 variety. Watch more on cold, flu and H1N1 symptoms »

"People need to take notice when they begin to feel bad. If they start to have respiratory problems, or are dehydrated because of a bug, they should go to the doctor. It could be H1N1 or seasonal influenza," says Shoham. "Some people with influenza can get very sick and could end up in the hospital if it's not taken care of."

People at greatest risk for catching H1N1 include young people ages 6 months to 25 years, pregnant women, and people with chronic health conditions like asthma, diabetes or heart and lung disease. The CDC recommends that these groups -- as well as health care workers -- get vaccinated first.

The seasonal influenza vaccination is especially important for people at high risk of serious flu complications, according to the CDC, including children ages 6 months to 18 years, people with immune system problems, women who plan on being pregnant during the flu season, those 50 years and older and health care workers.

But if someone doesn't fall into these categories, it doesn't mean he or she should skip vaccinations altogether. Experts say everyone should get both flu shots. "It's the best way to protect yourself," Shoham says.

Other than flu shots, are there other ways to stay healthy and avoid all of these bugs? Doctors say wash your hands and keep your fingers away from your mouth, nose and eyes. If you sneeze, sneeze into your elbow so as not to transfer your germs to your hands -- and everything else around you.

As for the myth about avoiding cold drafts -- forget it. "It doesn't seem to play out that sleeping with the window open, going out with your hair wet in the cold affects your immune system," Shoham says.

Also, keep your immune system healthy. That translates to eating well, getting enough sleep and staying active.

If you become ill and experience severe symptoms, see your doctor. Your physician may recommend antiviral drugs that can treat the flu. Antiviral drugs are prescription medicines (pills, liquid or an inhaled powder) that fight the flu by keeping the virus from reproducing in your body.

Above all, stay away from others. If you have the flu, the CDC recommends you stay home for at least 24 hours after your fever is gone. It's the best way to keep others from getting infected.
