Question:

Read the given passage and answer the questions that follow:-
The word AIDS means deficiency of immune system acquired during the lifetime of an individual indicating that it is not a congenital disease. AIDS was first reported in 1981 and in the last 25 years it has spread all over the world killing more than 25 million persons. AIDS is caused by the HIV (Human Immuno deficiency Virus). The people who are at high risk of getting this infection includes the individuals who have multiple sexual partners ,drug addicts who take drugs intravenously, individuals who require repeated blood transfusions and children born to an HIV infected mother. It is imperative for the physical and psychological well being that the HIV / AIDS infected persons are not isolated from the family and society. A widely used diagnostic test for AIDS is ELISA .AIDS has no cure, prevention is the best option.

Read the given statements .
Statement 1:- Treatment of AIDS using anti-retroviral drugs is only partially effective.
Statement 2:- Anti-retroviral drugs can prolong the life of patient as well as always prevent death.

Options:

Both the statements are correct

Only statement 2 is incorrect.

Only statement 1 is incorrect.

Both the statements are incorrect

Correct Answer:

Only statement 2 is incorrect.

Explanation:

The correct answer is Option (2) - Only statement 2 is incorrect.

AIDS has no cure, prevention is the best option. Anti-retroviral drugs are not a cure for HIV, but they are highly effective in managing the virus.

They suppress viral replication, allowing the immune system to recover and fight off infections.

Prior to the development of anti-retroviral drugs, HIV infection almost always progressed to AIDS, a condition that significantly weakened the immune system and led to death from opportunistic infections.

With consistent adherence to anti-retroviral therapy, people with HIV can achieve an undetectable viral load. This means the amount of virus in the blood is so low it cannot be detected by standard tests. An undetectable viral load prevents the progression to AIDS and dramatically reduces the risk of transmitting HIV to others.

While anti-retroviral drugs can't prevent death from all causes, they significantly improve life expectancy for people with HIV. With proper treatment, people with HIV can live a near-normal lifespan.
