HCV, HIV, and HBV are bloodborne viruses that contribute to substantial morbidity and mortality, with significant implications for public health.

• HIV, the virus linked to AIDS, damages vital CD4+ T cells, and weakens the immune system. 
• Hepatitis B is a liver disease caused by the HBV, leading to lifelong infection, liver cirrhosis, cancer, and potential fatality. 
• Hepatitis C, caused by the HCV, also results in persistent infection and poses risks of cirrhosis and liver cancer.

Early diagnosis and effective treatment of such blood-borne infections are an important strategy for the prevention of sexually transmitted disease.
