A HIV infected person has a weakened immune system as the HIV virus goes to the immune system and damages its function.

Direction: In each of the following questions, a statement of Asserti...
Assertion: HIV infected person is prone to opportunistic diseases.
Reason: Immune system weakens during HIV infection.
Explanation:
The correct answer is option 'A' which states that both the assertion and reason are true and the reason is the correct explanation of the assertion.
The HIV virus attacks and weakens the immune system of an infected person. This weakening of the immune system makes the person more susceptible to opportunistic diseases, which are diseases that generally do not affect individuals with a healthy immune system but can take advantage of the weakened immune system in HIV-infected individuals.
Here is a detailed explanation of why the reason is the correct explanation of the assertion:
1. HIV Infection and Immune System: HIV (Human Immunodeficiency Virus) specifically targets and attacks the CD4+ T cells, which are a type of white blood cells responsible for coordinating the immune response. As the virus replicates and destroys more CD4+ T cells, the immune system becomes progressively weaker.
2. Weakening of Immune System: The progressive destruction of CD4+ T cells leads to a decline in the ability of the immune system to effectively fight off infections and diseases. This weakening of the immune system creates an opportunity for opportunistic diseases to take hold in the body.
3. Opportunistic Diseases: Opportunistic diseases are caused by organisms that are typically harmless or kept in check by a healthy immune system. However, in the case of HIV-infected individuals, the weakened immune system cannot properly control these organisms, leading to the development of opportunistic diseases. Examples of opportunistic diseases include tuberculosis, pneumonia, candidiasis, and certain types of cancers.
4. Increased Susceptibility: HIV-infected individuals are more prone to developing opportunistic diseases due to their weakened immune system. These diseases can cause severe illness and can be life-threatening if not treated promptly.
In conclusion, the assertion that HIV-infected persons are prone to opportunistic diseases is true, and the reason for this is the weakening of the immune system during HIV infection. The weakened immune system creates an opportunity for opportunistic diseases to take hold and cause illness in HIV-infected individuals.
