Which disease is transmitted by all components or blood?-
**Core Concept**
The question is testing the understanding of a disease that can be transmitted through all components of blood. This concept is related to the transfusion-transmissible diseases, which are infections that can be spread through blood transfusions. The correct answer is a disease that can be transmitted through all blood components, including red blood cells, plasma, and platelets.
**Why the Correct Answer is Right**
The correct answer is Hepatitis B. Hepatitis B virus (HBV) can be transmitted through all components of blood, including plasma, platelets, and red blood cells. This is because HBV is a blood-borne pathogen that can infect liver cells and cause liver inflammation. The virus can be present in the blood of infected individuals and can be transmitted through transfusions, as well as through mother-to-child transmission during pregnancy.
**Why Each Wrong Option is Incorrect**
* **Option A:** Hepatitis C is another blood-borne pathogen, but it primarily infects the liver and is transmitted through plasma and other blood products, not through all blood components.
* **Option B:** HIV (Human Immunodeficiency Virus) is a blood-borne pathogen that primarily infects the immune system and can be transmitted through plasma and other blood products, but not through all blood components.
* **Option C:** This option is blank.
**Clinical Pearl / High-Yield Fact**
Hepatitis B is a significant concern in the context of blood transfusions, and all blood donations are screened for HBV. This highlights the importance of strict infection control measures in transfusion medicine.
**Correct Answer:** B. Hepatitis B.
