There are two parts—cells—involved here. Part one are the support cells. They can capture a chemical compound and craft a message saying: "Hey! I found something!" Part two are the network of nerve cells that carry that message up to the brain.

The part one support cells are more exposed to anything that wanders by, so they tend to get hammered first by whatever shows up.

Typically, with something like the common cold, a tiny handful of support cells get infected. A tiny handful are far too few to impact your sense of smell perception. However, these cells are also really good at noticing something's gone wrong and sending a different message: "I'M FUCKING FUCKED PLEASE KILL ME!" With that message, your body fires up with all that nifty inflammation and pumping out the mucus. People report a loss of smell afterward, what with their shit getting all blocked up. Ain't hard to understand at all. For most people, this is the total of their experience with Covid too. They treat it like a typical cold and move on with their lives. They get their smell back quickly once it's over because all that inflammation and shit protected most of the support cells. Plus these cells are meant to grow back from scratch pretty quickly.

Some few people have a different experience though. For them, Covid gets in there and rips up most of the support cells before their body reacts properly. They may have had too large of an initial blanketing dose, or the cells are too slow to notice something's invaded them, or their immune system's too busy watching t-cell porn over on /bio_d/, etc. What happens in this case is these people report a "loss of smell" before noticing any other symptom at all. Which is weird, because they know, you know, "the common cold don't do that!"

So Covid's sometimes a little scary for seeming to be a little different sometimes, if it don't flat out kill you that is.

Stuff can get more complicated as well, involving the part two never cells, the immune system flipping the fuck out, potential long term loss of smell, overall systemic injury, death, etc. But, as to why someone loses their smell from Covid, that it in a nutshell.

If you want to talk about protein spikes, and really understand all of why, you're gonna need a proper medical bioengeneer to wander by and explain things. Also, you might wanna take a two or three week course in high-school level cellular microbiology so as not to waste his time trying to explain should he happens to show up.
