You’re tired, you have a headache, a sore throat, and you’re sneezing. Is it a cold? Or is it the flu? Learn how to differentiate between these illnesses.
An acute upper respiratory infection (URI) is any infection of the nose or throat, which are part of the body’s upper respiratory system. URIs cause the common cold and tend to be relatively mild infections.
Strep throat is a highly contagious bacterial infection of the throat and tonsils, and needs to be treated with antibiotics. Strep is common in children, causing pain and redness in the throat, and often a fever. But adults can get it too.

Gastroenteritis (the stomach flu) and influenza (the flu) have different causes, and mostly different symptoms. But both can usually be treated at home—and a lot of the same precautions can keep you from getting either “flu” in the first place.
