Feeling sick? It could be this (and not the flu)

(CNN) -- Getting sick during winter isn't unheard of. For many, it's expected.

If you experience symptoms like a runny nose, sore throat, breathing problems and headache you may think it's the flu. But it could be another family of viruses known as adenoviruses.

In addition to flu-like symptoms, these kinds of viruses can also cause pink eye and diarrhea in children. The viruses may also lead to pneumonia, and in some extreme and very rare cases: death.

Most adenovirus infections are mild. Typically, the viruses are spread by coughing, sneezing, and direct contact with an infected person. You can also contract the viruses by touching items like door handles and light switches, where the viruses can live for long periods of time.

If you do get sick, the Centers for Disease Control and Prevention says symptoms typically last about 10 days. For most patients, home remedies and over the counter medicines to alleviate symptoms will be the only treatment necessary.
