26. Which infection interferes with the immune system, leaving the body open to other opportunistic infections?

Answer: A

Explanation:

HIV interferes with the immune system, leaving the body open to other opportunistic infections.

HIV is a virus that attacks the immune system, specifically targeting CD4 cells, which are crucial for immune response. As the virus progresses, it severely weakens the body’s ability to fight infections, making individuals susceptible to various opportunistic infections.

A) HIV

HIV is known for its significant impact on the immune system, leading to acquired immunodeficiency syndrome (AIDS) if untreated. This condition leaves the body unable to fend off infections and diseases that a healthy immune system would normally combat effectively.

B) MRSA

Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacteria resistant to many antibiotics. While it can cause serious infections, it does not directly interfere with the immune system to the extent that it predisposes the body to other infections like HIV does.

C) Tuberculosis

Tuberculosis (TB) is a bacterial infection that primarily affects the lungs but can also impact other parts of the body. Although TB can follow a weakened immune response, it is not a virus that directly compromises the immune system like HIV does.

D) Meningitis

Meningitis refers to the inflammation of the protective membranes covering the brain and spinal cord, usually caused by infections. While it can be severe, it does not inherently weaken the immune system or leave the body open to opportunistic infections in the same manner as HIV.

Conclusion

HIV is the only option that directly compromises the immune system, leading to a higher risk of opportunistic infections. In contrast, MRSA, tuberculosis, and meningitis function differently and do not have the same immunosuppressive effects as HIV. Therefore, HIV is the clear and definitive answer to the question posed.
