Answers
AIDS (Acquired Immuno Deficiency Syndrome)
● Caused by HIV (Human Immunodeficiency Virus) [HIV is a retrovirus (RNA virus)]
➡️ ● Transmission of HIV occurs through:
○ Sexual contact with infected person
○ Sharing infected needles (as in case of intravenous drug abusers)
○ Transfusion of contaminated blood
○ Infected mother to child through placenta.
● Time lag between infection and appearance of symptoms − Few months to many years (5-10 years)
➡️ ➡️ How does AIDS infection spread?
○ Virus enters the body of a person and enters macrophages.
○ Here, virus replicates (viral RNA reverse transcribes to viral DNA,
which gets incorporated into hosts DNA and subsequently new viral particles are produced).
○ Macrophages become a virtual HIV factory.
○ Thereafter, HIV enters helper T-lymphocytes, replicates, and produces
progenies.
○ As the progenies are released, they attack other T-lymphocytes.
○ Therefore, T-lymphocytes start decreasing in number and immune
response of the person becomes weak.
○ Even infections which could be overcome easily start aggravating.
● Diagnosis of AIDS − By ELISA (Enzyme Linked Immuno Sorbent Assay)
● Treatment − No permanent cure; antiretroviral therapies can prolong
the life of patient
✴️ Prevention of AIDS
○ Ensuring use of disposable syringes
○ Screeningblood from blood banks
○ Advocating safe sex
○ NACO (National AIDS Control Organization) and many NGOs are
doing a lot to create awareness among people.
