People who know blood?!
Question:
People who know blood?
If there is dried up blood on something how long does it take for it not to be dangerous. I guess like not to catch hiv or something
Answers:
All blood, whether dried or fresh, should be considered potentially infectious. The CDC (Center for Disease Control) states that on environmental surfaces at room temperature:
1. Hepatitis B can live for up to 7 days.
2. Hepatitis C viruses can live for 16 hours to 4 days.
3. HIV "does not survive well" outside the body. In the lab, the virus has been shown to reduce 90-99% after several hours of drying on a surface. No known cases of HIV have been spread through dried blood.
