What is called a taste is 90% in reality smell that reaches the nose from behind over the throat cavity. The nose even reacts differently to smells, depending on where they come from. That explains why makers smell cheese bad, but tastes delicious.
In colds with colds, the nose is often clogged, so that the smells do not reach the odorous mucosa at all, so that the food does not taste.

Even with heavy colds and flu, the smelling capacity is usually preserved, nothing comes to smell. As soon as the mucus is gone, you smell again.
The SARS-CoV-2 also damages or kills odor cells, so you can wait for months until they have recovered or have been replicated.
The virus does not only cause respiratory diseases, but also attacks the vessels and others.

even with light, “cold” the nasal mucosa are irritated and react with increased mucus production. This makes the “substance exchange” more difficult with the odor organs and thus weakens the sense of smell.
