In the field of epidemiology, synthetic blood holds significant importance due to its potential to address several key health challenges: - Blood Shortages: Natural blood supplies often face shortages, especially during major outbreaks or disasters. Synthetic blood can help mitigate these shortages. - Transfusion-transmitted Infections (TTIs): Traditional blood transfusions carry the risk of TTIs, such as HIV and Hepatitis B. Synthetic blood eliminates these risks. - Universal Compatibility: Synthetic blood has the potential to be universally compatible, reducing the need for blood typing and cross-matching.
