The loss was so complete that I couldn't smell household garbage, taste strong blue cheese or get anything from extremely spicy chilis except for the physical sensation - it was quite eery and very unlike the reduced senses you'd get with the common cold.
Other symptoms included an intermittent headache and nausea. Nothing else except for coughing very rarely and a fever that never topped 100.
Definitely not research but I've read several comments on /r/italy that were mentioning just that, i.e. loss of smell combined with loss of taste for some of the commenters in there or their friends/acquaintances (who also had other covid-related symptoms). I've first read this 3 or 4 or days ago, so it was not written as responses to articles like these (which have started showing up in the last two or so days).
It could be related to the fact that Spring is starting in the Northern Hemisphere, and thus, the body reacts to the increased amount of polen in the air.
I'm allergic, so it's normal for me to suffer those symptoms every Spring.
I could smell laundry detergent very faintly so I know I had not completely lost the sense. I also felt a pain in the back of my nose/top of head as if I had water go up it, so I assume something was irritating that part of my nose. A dry cough has started to take place only after the fever stopped and I noticed my breathing is a bit harder than before the virus took over.
