Hi, Recently i travelled in a train in india and i opened my food. it was rice biriyani. in between i had to go and wash my hands and there was no one in that area near to the food. when i came back, i saw a railway sweeper coming out from the place where this food was kept in an open posiion. when i came back i took the food immediately. Now i am tensed thinking about this, and worries whether that fellow had mixed some infected blood in that food. to increase the worry, i had a small cut on my lips at that point of time. Since i immediately had the food, the time gap was hardly a few seconds. i know the fact that the hiv virus dies quickly in outside environment but this was only a few seconds. Can any one tellme what is the risk involved, if any sort of this kind has happened? Do i need to test for hiv? i am completely worried and has sleepless nights after this incident.
