can someone give me ideas of how i can write article about how coronavirus has affected the small business?

Yah!

Explanation:

You can start with writing about a small business like a restaurant. You can say that since the coronavirus is contagious and spreads fast people have to stay inside. Resturants can't do business because that would mean sitting on seats people have already been on Which would spread a lot of germs. You could also write about how the people in the kitchen could already be sick and cough or sneeze in the food.
