Uh oh. Sore throat, runny nose, yucky cough, drippy eyes. You started your day feeling well, but as the day went by, you started to get sicker and sicker – the symptoms just keep piling on. This all probably sounds familiar because chances are, you’ve had an upper respiratory infection before.
Upper respiratory infections (URIs) are common and they happen to everyone at one time or another. In 2019, there were over 17 billion worldwide cases reported. But did you know URIs are not one single illness? Here’s how to recognize a URI, the different types of infections, and what to do if you get one.
What is an upper respiratory infection?
Let’s take it back to elementary school for a minute. Imagine one of those 3D, plastic human anatomy models. Looking at the model, find the mouth, throat, lungs, nose, voice box, diaphragm, windpipe. See how the body parts you use to breathe and speak are all connected? That’s the respiratory system The respiratory system can be divided in half into the lower respiratory system (the lungs and windpipe) and the upper respiratory system (the throat, mouth, nose, nasal cavity, and voice box).
An infection occurs when a virus invades your respiratory tract. How do you pick up a virus? You can pick it up anywhere by simply touching a surface or shaking a hand that has the bacteria on it and then touching your nose or mouth. Respiratory infections are more common than other types of infections because of how we interact with the world. Upper respiratory infections are more common than lower. This is a good thing because lower respiratory infections (LRIs) are usually more severe.
Some of the most common kinds of URIs include:
- The common cold
- Sinus infection
