Continue to observe: From your question, I cannot tell with what you were ill. If you have/had Covid-19, new loss of taste or smell is one of the symptoms. It is unclear how long that may last. Many patients report that it lasts well after other symptoms have resolved. If you are otherwise well, you can observe for the next few weeks and contact your doctor if it persists.
