Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,
                    "explanation": "EXPLAIN WHY THE ANSWER IS CORRECT"

            ]

            sea, 
vomiting, myalgia, headache 
weight lass, pharyngitis, skin 
rashes (roseola-like or 
urticarial), lymphadenopathy; 
symptoms clear in cells/uL
about 1-2 wk
HIV antibody—negative at start 
of syndrome Seroconversion 
occurs near end of the 
syndrome.
CD4+ and CD8+ lymphocytes 
reduced in numbers, but >500 
cells/µL. 
After acute symptoms, they 
tend to return toward normal 
levels.
ELISA and Western blot are 
positive.
The severity of the acute 
syndrome varies among 
infected persons. 
The period for seroconversion 
of 30% of patients without 
acute symptoms varies and 
can be 1-6 mo or longer.

Stage 2: latent 
period 
(asymptomatic 
stage)
Median time from initial 
infection to onset of clinical 
symptoms: 8-10 years -50%-
70% of patients develop PGL
ELISA and Western blot are 
positive. A slow but usually 
steady increase in viral load. 
Usually, a steady decline in 
CD4+ cell count; CD4+/CD8+ 
ratio begins to approach 1
Viral replication is ongoing 
and progressive.
A steady decline in CD4+ cell 
counts occurs, except in the 
fewer than 1% who are 
nonprogressors (also have 
low viral load).
Stage 2: early 
symptomatic stage
Without treatment, lasts for 1-3 
yr, any of the following: PGL, 
fungal infections, vaginal yeast 
and trichomonal infections, oral 
hairy leukoplakia, herpes zoster, 
herpes simplex, HIV retinopathy 
Constitutional symptoms: fever, 
night sweats, fatigue, diarrhea, 
weight loss, weakness
ELISA and Western blot are 
positive. HIV antigen, RNA, and 
DNA tests are positive.
Signs and symptoms increase 
as CD4+ cell count declines and 
approaches 200/µL; often 
between 200 and 300/µL. 
Viral load continues to increase
Platelet count may decrease in 
about 10% of patients.
The spectrum of disease 
changes as CD4+ cell count 
declines.

Stage 3: AIDS
Opportunistic infection(s): 
Pneumocystis
jiroveci pneumonia, 
cryptococcosis, tuberculosis, 
toxoplasmosis, histoplasmosis, 
others.
Malignancies: Kaposi sarcoma, 
Burkitt lymphoma, non-
Hodgkin lymphoma, primary 
CNS lymphoma, invasive 
cervical cancer, carcinoma of 
rectum, slim (wasting) disease
High viral load; CD4+ cell count 
<200/μL CD4+ cell count 
<50/µL at high risk for 
lymphoma and death
Platelet count may be low.
Neutrophil count may be low.
ELISA and Western blot are 
positive. 
HIV antigen, RNA, and DNA 
tests are positive.
Death usually occurs 
because of wasting, 
opportunistic infection, or 
malignancies.
The use of combination 
antiretroviral agents has 
slowed the death rate, but 
long-term outlook must 
depend on vaccines for
prevention and treatment 
because the virus promotes 
resistance to these agents.

Persistent generalized lymphadenopathy :
An early sign of HIV infection found in about 70%
of infected patients during the latent stage of
infection. And posterior cervical, submandibular,
