I was at work and accidentally cut my hand with knife. there was no blood coming out. am i at risk of getting hiv from this?

No: HIV transmission is not likely in above scenario. Make sure your tetanus shot is up to date and watch the wound until healed as a superficial wound infection remains possible.

Agree with Dr. P: Get tetanus booster. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
