Hello doctor , my concern is Yesterday I was walking on road , my shoe laces got opened up , which I tied as soon as this happened , and did not wash my hands , but I realised later that I ate biscuits after tieing my shoe laces with those hands , Now my mind is thinking that , since my laces touched the road and other various areas and dog and other animals live on the road So should I be concerned that I may get affected by any disease either Rabies or any other disease ???  Please reply
