What virus is responsible for causing AIDS?

• A. HIV
• B. HBV
• C. HCV
• D. HPV

Answer: (A)

The virus responsible for causing AIDS is HIV, which stands for Human Immunodeficiency Virus. This virus attacks the immune system, specifically targeting CD4 cells (T cells), which are crucial for fighting off various infections. Over time, if untreated, HIV can lead to the progressive deterioration of the immune system, culminating in AIDS (Acquired Immunodeficiency Syndrome). This syndrome is characterized by the body's inability to fend off opportunistic infections and certain cancers, making it a critical condition that results from the advanced stage of HIV infection. Other viruses listed have different impacts; for instance, HBV (Hepatitis B Virus) primarily affects the liver, leading to conditions such as liver cirrhosis or liver cancer. HCV (Hepatitis C Virus) also affects the liver but is separate from the immune deficiency effects of HIV. HPV (Human Papillomavirus) is known for being linked to different forms of cancer, particularly cervical cancer, but is not related to the immune system's functioning as HIV is. Thus, understanding these differences is crucial in the field of virology and healthcare, emphasizing why HIV is specifically associated with AIDS.
