Baby recovered from Covid

My 14 mths old baby just recovered from Covid a week ago and he doesn't seems to eat as much as before, has been having rice, vege, meat etc for his daily meal. Now only to eat a few bites, and mostly drink milk and water. Does it affect his appetite, is there a possibility of him lossing his taste bud due to Covid? Will he regain his taste bud? If yes how long it will take to regain it? For now what I can give him for nutrients? #pleasehelp
