Hi, My husband gets cold sores. I have never had one but I know I could still carry the virus. I was drinking from a straw and then my elbow bumped it. Any chance of getting the virus on my arm from this? I don't believe I have any open skin on my elbow but I went ahead and used purell on it. After, I realized that the hand i used to rub purell on my elbow had a small cut. Any chance of whitlow from this?
