Which term refers to a disease that spreads through the body via the bloodstream?

• A. Parasitic Disease
• B. Hepatitis
• C. Direct Transmission
• D. Systemic Infection

Answer: (D)

Systemic infection describes a disease that spreads beyond the initial site through the bloodstream, circulating pathogens to multiple organs and causing widespread symptoms. The bloodstream acts as a highway that carries the infectious agents to distant tissues, which is why you see effects in several body systems rather than just at the entry point. A localized infection stays confined to one area and doesn’t disseminate throughout the body. Direct transmission refers to how the disease is passed from one person to another, not how it travels inside the body after infection. Hepatitis is a liver-specific inflammation and, while viruses can travel in blood, the term itself denotes liver involvement rather than general hematogenous spread. Parasitic disease is a broad category and isn’t specific to dissemination through the bloodstream. So, the term that fits a disease spreading through the body via the bloodstream is systemic infection.
