What is the Influenza Virus?

 It’s beginning to look a lot like Christmas, and it’s beginning to sound like a runny nose.

Scientifically known as seasonal influenza, the flu is a viral respiratory infection experienced by between five and 20 percent of Americans every year.

The influenza virus is spread through direct and indirect contact with infected individuals.

Infectious disease specialist MaryAnn Tran, M.D., an assistant professor of medicine at Michigan State University, said the flu is transmitted within a three to six foot range.

Tran also said there is a different strain of the virus every season, and its mutation rate is second likely to only HIV.

 Many major symptoms of the flu are similar to the common cold; however, complications that arise from the virus can be much more serious, ranging from bacterial infections to death.

Tran said infants, the elderly, pregnant women, and individuals with co-morbidities (such as heart disease) are among those who are most at risk for serious flu complications.

 However, she said for the most part, the college-age demographic is not at risk.

           

“A young, healthy person probably won’t [have many complications],” said Tran.
