As an expert in the field of microbiology and infectious diseases, I can provide you with information on the transmission of diseases through blood.
Blood can indeed carry diseases, especially if it is fresh and contains viable pathogens. However, once blood dries, the environment becomes less conducive to the survival of most pathogens. The drying process can lead to the death of many bacteria and viruses due to the lack of moisture, which is often essential for their survival.
That being said, some diseases, particularly those caused by viruses like HIV and hepatitis, can potentially be transmitted through dried blood under certain conditions. For instance, if the dried blood contains a high concentration of the virus and comes into contact with broken skin or mucous membranes, there is a risk, albeit a significantly lower one compared to fresh blood.
It's important to note that the risk of transmission from dried blood is generally considered to be low, and proper precautions such as wearing gloves and avoiding direct contact with blood can further minimize the risk.

This is because certain bloodborne viruses can live for days outside the body and still cause infection. Hepatitis B virus can live in dried blood for up to a week.1Hepatitis C virus can survive for up to four days. ... disinfect surfaces that may have been in contact with blood or other body fluids*.
