What is the name of the bloodborne pathogen that weakens the immune system by destroying white blood cells?

The Human Immunodeficiency Virus (HIV) is the pathogen that specifically targets the immune system by attacking and destroying white blood cells known as CD4 cells or T-helper cells. This reduction in the number of these crucial immune cells leads to a weakened immune system, making the body more vulnerable to infections and diseases. As the infection progresses without treatment, it can lead to Acquired Immunodeficiency Syndrome (AIDS), severely compromising the individual's ability to fight off common illnesses.

In contrast, Hepatitis C Virus primarily affects the liver and does not directly attack the immune system in the same way HIV does. The Herpes Simplex Virus causes outbreaks of sores and can remain dormant in nerve cells but also does not target white blood cells directly. MRSA, or Methicillin-resistant Staphylococcus aureus, is a type of bacteria resistant to certain antibiotics and does not relate to bloodborne pathogens that target the immune system. Understanding the specific actions of each pathogen is essential for recognizing the implications for health and safety, especially in a skin care or beauty context.
