Thanks for your question. I would not worry about getting HIV or Hepatitis this way.These infections are not spread through surfaces or casual contact.
You cannot get HIV from touching contaminated surfaces, even if there are cuts on your hands. HIV dies within seconds after it is out of a human body, so there would be no virus left in the blood by the time you touched it.
Hepatitis C can live a little bit longer outside the body, but it is still unlikely you could get Hepatitis C this way. It is not impossible – if there was enough blood and it entered into your open cut, it could transmit the virus. In practice, though, we are not seeing this happen very often.
Hepatitis B is also spread by blood-to-blood contact, but there is a vaccine that can protect you from getting Hepatitis B. If you are not already vaccinated against Hepatitis B, ask for the vaccine through your doctor or public health unit.
In general, it’s a good idea to keep cuts covered with bandaids or gloves until they are healed over (not bleeding), just to reduce risks of transmission. If you are concerned, you could get a blood test for Hepatitis C at your doctor or at an STI clinic.
