Post-Viral Olfactory Loss
The most common condition to impact the olfactory nerve is the common cold, but other viral illnesses can have the same effect.
You probably know that when nasal congestion fills your sinuses, it can result in a lowered ability to smell that comes back after the congestion clears up.
Sometimes, though, it takes a while to come back all the way. This is called post-viral olfactory loss (PVOL), and everyone probably experiences it at some point. Researchers don't understand exactly why this happens, but they suspect it's because certain viruses—including the common cold and influenza—somehow damage the mucous membrane and the olfactory epithelium.
