What is HIV
•Human: Infecting human
beings
•Immunodeficiency: Decrease
or weakness in the body’s
ability to fight off infections
and illnesses
•Virus: A pathogen having the
ability to replicate only inside a
living cell
What is AIDS
.Acquired: To come into
possession of something new
.Immune Deficiency:
Decrease or weakness in the
body’s ability to fight off
infections and illnesses
.Syndrome: A group of signs
and symptoms that occur
together and characterize a
particular abnormality
6. Basic Term
Antigen: A substance which is
recognized as foreign by the immune
system. Antigens can be part of an
organism or virus, e.g., envelope, core
(p24) and triggers antibody
production.
Antibody: A protein
(immunoglobulin) made by the
body’s immune system to recognize
and attack foreign substances
Disease Progression
• Severity of illness is determined by amount of virus
in the body (increasing viral load) and the degree of
immune suppression (decreasing CD4+ counts)
• As the CD4 count declines, the immune function
decreases.
Window Period
• Time from initial infection
with HIV until antibodies
are detected by a single test
• Usually 3-8 weeks before
antibodies are detected
• May test false-negative for
HIV antibodies during this
time period
• Can still pass the virus to
others during this period

Difference Between HIV and
AIDS
• HIV is a virus and AIDS is
disease
• HIV develops into AIDS
• AIDS is deficiency in the
body’s defense mechanism or
immune system
• AIDS is acquired not
hereditary
How does HIV make a
person Sick?
• Immune suppression
leads to opportunistic
infections
• Direct infection of major
organs
Brain (HIV
encephalopathy)
Kidney (HIV
nephropathy)
Heart (HIV
cardiomyopathy)

Why HIV Rates not going Down
Sex at an early age
Little life-skills and sex education
Little condom use
Multiple partners
Stigma and Discrimination
Sex for money or sex for .....things
Substance abuse: Ganja, cocaine,
alcohol
Men having sex with men &
homophobia
Gender inequity and gender roles

Magnitude of HIV/AIDS
• First HIV case in India was reported from Chennai in
1986
• First AIDS case ws reported from Mumbai in 1987
• Approximately 2.27 million PLHIV in India
• HIV cases are now reported from all states of India
• All districts are classified into categories A, B, C and D
based on prevalence in antenatal women and high risk
groups

17. Pre-Exposure Prophylaxis (PrEP)
Meaning
•Pre-exposure Prophylaxis: A pharmacologic HIV prevention
intervention for persons at high risk of becoming infected with
HIV.
•An HIV-uninfected individual takes antiretroviral medication(s)
before potential HIV exposure
•The use of medication for prophylaxis is well established:
–Use of contraceptive methods to prevent pregnancy
–Use of antimalarial medications before traveling to endemic
areas

Use of Antiretrovirals for HIV Prevention
•Prevention of mother-to-child transmission
–Antiretrovirals given to the mother during
pregnancy, labor, and delivery and to the infant
postpartum[1]
–PMTCT has nearly eliminated perinatal HIV infection
in the US and other developed countries
•Post-exposure prophylaxis
–Antiretrovirals given within hours of a known or
suspected HIV exposure (eg, needle stick injury, rape,
unprotected sexual intercourse with someone whose
HIV status is unknown )

19. Pre- Vs Post-exposure Prophylaxis
• After exposure to HIV,
infection may become
established
• Postexposure
prophylaxis (initiated
soon after exposure)
reduces the chance of
infection
• Pre-exposure prophylaxis
begins treatment earlier
(before exposure)

Charotar University of Science & Technology
Accredited Grade “A” with NAAC & KCG
Meaning
It refers to the use of
Antiretroviral
Prophylactically to prevent
HIV infection following an
occupational exposure
General Guideline
• Potential benefits weighed
against potential risks and to
inform the staff
• Adherence and adverse
effects be monitored
• Baseline HIV test of staff
with counseling
• Follow-up:
Counseling and HIV
testing
Monitor for drug toxicity
22. Steps for Post EP
• Assess nature of exposure
• Assess HIV status of source of
exposure
• PEP evaluation
• PEP Regimens-Drugs and Dosage
for PEP
• Follow up

Module 1: Overview of HIV Infection
Trainer Notes:
The trainer explains the HIV Estimates in different states in India, as shown in the graphic
Declining trends in adult HIV prevalence are sustained in all of the high prevalence States (Andhra Pradesh & Telengana, Karnataka, Maharashtra, Manipur, Nagaland and Tamil Nadu) and other States such as Goa, Odisha and West Bengal
Stable adult HIV prevalence has been noted in States such as Bihar, Chhattisgarh, Gujarat, Mizoram, Rajasthan and Uttar Pradesh
However, rising trends in adult HIV prevalence has been observed in some of the hitherto relatively low prevalence States/UTs like Assam, Chandigarh, Delhi, Jharkhand, Punjab, Tripura and Uttarakhand
Among the states/UTs, in 2015, Manipur has shown the highest estimated adult HIV prevalence of 1.15%, followed by Mizoram (0.80%), Nagaland (0.78%), Andhra Pradesh & Telengana (0.66%), Karnataka (0.45%), Gujarat (0.42%) and Goa (0.40%)
Besides these States, Maharashtra, Chandigarh, Tripura and Tamil Nadu have shown estimated adult HIV prevalence greater than the national prevalence (0.26%)
Odisha, Bihar, Sikkim, Delhi, Rajasthan and West Bengal have shown an estimated adult HIV prevalence in the range of 0.21–0.25%.
All other States/UTs have levels of adult HIV prevalence below 0.20%
