Flu Symptoms in Adults, Children: 2012 Season Reaching 'Moderately Severe' Levels, Says CDC

The flu season is upon us, and it's hitting hard this year.

Reports of influenza-like-illnesses (ILI) have jumped from 2.8 percent to 5.6 percent in the past four weeks, and widespread cases litter the majority of the U.S., according to the Center for Disease Control.  In contrast last season registered a maximum of only 2.2 percent ILIs.

"Reports of [ILIs] are nearing what have been peak levels during moderately severe seasons," says Dr. Joe Bresee. "While we can't say for certain how severe this season will be, we can say that a lot of people are getting sick with influenza and we are getting reports of severe illness and hospitalizations."

It is still possible to contract the flu despite taking immunization precautions, and those who are over 65, young children, and pregnant women are at a higher risk of serious complications than others.

Symptoms include fever, sore throat, chills, a cough, runny or stuffy nose, headaches, muscle or body aches, fatigue, and potentially diarrhea and vomiting. Infants will often experience poor circulation, lethargy, swollen glands, and a lack of appetite.

Once infected, most people have the ability to sicken others between five and seven days after symptoms become apparent. The illness can also be transferred up to one day before any effects are felt. However, the CDC clarifies that "young children and people with weakened immune systems might be able to infect others for an even longer time."

Contagious people can spread the flu through sneezing, coughing, or talking nearby others. Make sure to be careful of surfaces or objects that flu afflicted friends or family touch, as the virus can be spread in that manner as well.

Bresee asserts, "Anyone who has not already been vaccinated should do so now."

Stay safe and don't hesitate to seek medical attention if you experience any of these symptoms.
