My Friend Has A Cold Sore And Gave Me A

My friend has a cold sore and gave me a piece of food on her fork to try. I pulled the food off the fork with my fingers and ate the piece of food not realising she had the cold sore til later. She told me it was day 5 of her cold sore and took medicine as soon as she got symptoms on day 1 and that the cold sore had mostly crusted over. Is there a chance I have the virus. Just worried as I have never had a cold sore before and I have a 13 month old son who I don't want to get anything either. This happened approx 24 hours ago. Thanks
