India has the third largest HIV epidemic in the world.
In India (2016)
Approx. 2.5 million people living with HIV.
0.3% adult HIV prevalence.
86,000 new HIV infections.
HIV prevention in India- NACO is the body responsible for
prevention and control of the HIV epidemic in INDIA.
Current programme, NACP-IV (2012-2017) , aims to reduce the
HIV infections by 50%.
The rate of HIV transmission during pregnancy, labor or
delivery from mothers infected with HIV is
25% - 30% with no interventions
But can be reduced
up to <2% with
appropriate intervention.

Preferred regimen-
Tenofovir 300mg + Lamivudine 300mg+ Efavirenz 600mg
Alternate regimen
Azathioprine + Lamivudine + Efavirenz,
Azathioprine + Lamivudine + Nevirapine,
Tenofovir + Lamivudine + Nevirapine
According to NACO guideline- Dec 2013
Previous it was single dose Nevirapine.
Daily Nevirapineprophylaxis for 6 weeks
If mother received ART
adequately in the antenatal period
Daily Nevirapineprophylaxis for 12 weeks
If mother has not received ART
Received ART for less than 24
weeks
OR
According to NACO guideline- Dec 2013
1) Exclusive breastfeeding is the recommended infant feeding
choice in the first 6 months.
2) In situations where breastfeeding cannot be done (maternal
death, severe maternal illness) or individual mother’s choice (at
her own risk), then exclusive replacement feeding may be
considered only if AFASS Criteria for exclusive replacement
feeding is fulfilled.
3) After 6 months complementary feeding should be introduced
gradually.
4) MIXED FEEDING should NOT be done during the first 6
months. (Feeding a baby with both breast feeds and
replacement feeds in the first 6 months is known as mixed
feeding which leads to mucosal abrasions in the gut of the baby
facilitating HIV virus entry through these abrasions).
• Breastfeeding continued until 12 month of age.
If EID Is negative
• Breastfeeding continue until the baby is 2 year old.
If EID Is positive
Breast-feeding should NOT be stopped ABRUPTLY

Integrated Counsellingand Testing Centres
An ICTC is a place where a person is counseled and tested for
HIV, on his/her own will (self- initiated) or as advised by a
medical provider (provider- initiated).
Functions of ICTC
Early detection of HIV
provide basic information on modes of transmission and
prevention of HIV for promoting behavioural changes and
reducing vulnerability.
Linking PLHIV with other HIV prevention, care and
treatment services.
ICTC
Fixed ICTC
Standalone ICTC

CLINICAL GOALS : Prolongation of life and improvement in quality of
life
VIROLOGICAL GOALS : Greatest possible reduction in viral load for as
long as possible
IMMUNOLOGICAL GOALS : Immune reconstitution both quantitative
and qualitative
THERAPEUTIC GOALS : Rational sequencing of drugs that achieves
clinical , virological and immunological goals while maintaining treatment
options limiting drug toxicity and facilitating drug adherence
REDUCTION OF HIV TRANSMISSION : By suppression of viral load
ART should be initiated in all adults, adolescent , pregnant and breast
feeding living with HIV regardless of WHO clinical stage and at any
CD4 cell count
As a priority, ART should be initiated in all with severe or advanced
HIV clinical disease{WHO clinical stage 3 and 4}and with CD4 count
<350cells/mm3
In infant and children younger than 10 years of age:
Infants diagnosed in the first year of life
Children living with HIV 1 year old to less than 10 year
Children <2 years and younger than 5 years of age with WHO clinical
stage 3 & 4 & or CD4 count <750 cells/mm3 and 5 years of age and

"Post exposure prophylaxis" (PEP) refers to the comprehensive management given to minimize the risk of infection following potential exposure to blood-borne pathogens (e.g.HIV,HBV,HCV).
It includes-1. First aid
2. Counseling
3. Risk assessment Relevant laboratory investigations based on
informed consent of the source and exposed person.
4. Depending on the risk assessment, the provision of short term (4
weeks) of antiretroviral drugs.
6. Follow up and support.
Exposure route risk
Blood transfusion 90-95%
perinatal 20-40%
Sexual exposure 0.1-10%
vaginal 0.05-0.1%
anal 0.065-0.5%
oral 0.005-0.1%
Needle stick exposure 0.3 %
• Immediately wash the wound with water and soap.Skin
• Irrigate exposed eye immediately with water or normal salineEye
• Spit fluid out immediately
• Rinse the mouth thoroughly, using water or saline and spit again
Mouth
Mild exposure
• Mucus membrane /non intact skin with small volume
• e.g. superficial wound with plain or low calibreneedle
Moderate exposure
• Mucus membrane /non intact skin with large volume.
• cut or needle stick injury penetrating gloves.
Severe exposure
• Percutaneous with large vol.
• An accident with caliber needle visibly contaminated with blood.
Step 2.1-assessing nature of exposure and risk of transmission
• PEP is not effective when given more than 72 hours after exposure. A baseline rapid HIV testing should be done before starting PEP.• Initiation of PEP where indicated should not be delayed while waiting for the results of HIV testing of the source of exposure.• Informed consent should be obtained before testing of the source as per national HIV testing guidelines.
PEP must be initiated as soon as possible, preferably within 2 hours
Source h.i.v status
Definition of risk
h.i.v. negative Source is not h.i.v. infected
Low risk h.i.v positive and clinically asymptomatic
Moderate risk h.i.v. positive and clinically symptomatic
unknown Status of patient is unknown (risk assessment will be based upon h.i.v. prevalence in that locality)
• The exposed individual should have confidential counseling and assessment
by an experience physician.
• The exposed individual should be assessed for pre-existing HIV infection
intended for people who are HIV negative at the time of their potential exposure
to HIV.
• Exposed individuals who are known or discovered to be HIV positive should
not receive PEP. They should be offered counseling and information on
prevention of transmission and referred to clinical and laboratory assessment
to determine eligibility for antiretroviral therapy (ART).
• Exposed persons should receive appropriate information about PEP and risk
and benefits of PEP in order to get informed consent.
• It should be clear that PEP is not mandatory.
• Psychological support: Many people will feel anxious after exposure. This
will help to relieve part of the anxiety, but some may require further
specialized psychological support.
.
• HIV testing of the source patient should not delay the decision about
whether or not to start PEP.
• In the case of a high risk exposure from a source patient who has
been exposed to or is taking antiretroviral medications, consult an
expert to choose the PEP regimen, as the risk of drug resistance is
high.

Consider 2-drug PEP
SEVEREStart 3-drug PEP Start 3-drug PEP Usually no PEP or
Consider 2-drug PEP
Step 4.1-Deciding on PEP regimen
There are two types of regimens-
• Basic regimen: 2-drug combination (Zidovudine, Stavudine)• Expanded regimen: 3-drug combination (Zidovudine, Stavudine, Lamivudine)
• All clients starting on PEP must take 4 weeks (28 days) of medication.
Step 4.2 Selection of the PEP regimen when the source patient is
known to be on ART:
The physician should consider the comparative risk represented by the
exposure and information about the exposure source, including-
history of and response to antiretroviral therapy based on clinical response,
CD4cell counts,
viral load measurements(if available)
current disease stage (WHO clinical staging and history).
When the source person's virus is known or suspected to be resistant to one or
more of the drugs considered for the PEP regimen, the selection of drugs to
which the source person's virus is unlikely to be resistant is recommended.
• All clients starting on PEP must take 4 weeks (28 days) of medication.
• In all cases, the first dose of PEP should be offered as soon as possible, once the decision to give PEP is made.
• HIV testing or results of the source HIV test can come later.
Step 4.3 Amount of Medication to dispense for PEP
The reason for HIV testing soon after an occupational exposure is to establish a
"baseline“ against which to compare future test results.
• If the person is HIV-negative at the baseline test, it is in principle possible to prove
that subsequent infection identified by follow-up testing is related to the occupational
exposure (Depending on the timing of infection and consideration of other risks or
exposures) .
• When offered HIV testing, the exposed person should receive standard pre-test
counseling according to the national HIV testing and counseling guidelines, and
should give informed consent for testing.
• Confidentiality of the test result must be ensured..
Do not delay PEP if HIV testing is not available.
Step 5 – Laboratory Evaluation
• An exposed person should be advised to use precautions (e.g., avoid
blood or tissue donations, breastfeeding, unprotected sexual relations or
pregnancy) to prevent secondary transmission, especially during the first
6-12 weeks following exposure. Condom use is essential.
Whether or not PEP prophylaxis has been started, follow up is indicated
to monitor for possible infections and provide psychological support.
Step 6- FOLLOW UP
LABORATORY FOLLOW UP
• Follow-up HIV testing: exposed persons should have post-PEP
HIV tests at the completion of PEP
• Therefore, testing at 3 months and again at 6 months is
recommended.
Adherence and side effect counseling should be provided and
reinforced at every follow-up visit. Psychological support and
mental health counseling is often required.

The epidemic continues to progress with the following
characteristics
High risk groups to low risk groups
Urban to rural areas
High prevalence states to all states
High vulnerability of young persons and women
MSM and IDUs not received appropriate attention
Growing number of people living with HIV/AIDS has
increased the need for care , support and treatment
Providing psychosocial support to the infected and affected individual esp. to marginalised woman and children affected by epidemic
Ensure accessible, affordable and sustainable treatment services.
Free antiretroviral therapy
Prevention and treatment of opportunistic infections including TB
Facilitating home based care and impact mitigation
Medicine Departments of Medical Colleges and District hospitals.
Based on prevalence of HIV in the region
Provide free comprehensive services including ART, CD4
testing & drugs required for treatment of Opportunistic Infections.
“306 centres providing freeART to more than 4,12,125 patients in
India”.
Main constraints-- Distance, travel time and costs to access ART services and adherence to treatment.
Leads to--Poor drug adherence, lost to follow up and missed cases.
Make -- Accessible and facilitate delivery of ARV drugs, Link ART Centres are established , located at district level hospitals nearer to the patient’s residence.
Located -- Integrated Counseling and Testing Centres (ICTC) which further helped in linkage between ICTC and ART
April 2011-- “612 Link ART Centres facilitate delivery of services nearer to the patients homes”
Patients needed to travel long distance to access the second line
treatment. This issue has resulted in low uptake of second line treatment.
In View of these, it was decided to expand the number of facilities that
can provide second line ART.Previously till 2009 it was given in 2 COE.
For this, some good functioning ART Centres were upgraded & labelled
as ‘ART Plus Centres’

TB and HIV co-infection is when people have both HIV infection, and also either latent or active TB disease. Each disease speeds up the progress of the other.
The estimated 10% activation of dormant TB infection over the lifespan of an infected person, increases to 10% in one year, if HIV infection is superimposed.
TB is one of the most commonly occurring opportunistic infections in HIV infected patients.
HIV and TB interact in several ways:
- Reactivation of latent infection.- Primary infection.- Recurring infection.- In the community.
“When a virus (HIV) and a bacteria (TB) can work so well together, why can't we?”
- UNAIDS
1. Huge dual burden of both HIV and TB. 2. High mortality of TB-HIV coinfection. 3. Large country with heterogeneous HIV
epidemic. Health system capacity varies tremendously.
4. Late diagnosis of HIV. 5. Leaky care cascade for HIV: difficult to track LFU.6. Airborne infection control difficult due to over-
congested health facilities.
Purpose: The overall purpose is to articulate the national policy for TB/HIV Collaborative Activities between RNTCP and NACP so as to ensure reduction of TB and HIV burden in India.
Objectives:
1. To maintain close coordination between RNTCP and NACP at National, State and District levels.
2. To decrease morbidity and mortality due to TB among persons living with HIV/AIDS
3. To decrease impact of HIV in TB patients and provide accessto HIV related care and support to HIV-infected TB patients.
4. To significantly reduce morbidity and mortality due to HIV/TB through prevention, early detection and prompt managementof HIV and TB together.

Started from February 1, 2017. People who have been tested positive for HIV, and those affected
with tuberculosis, have to collect Fixed Dose Combination (FDC) from district hospital and ART centre to be taken on a daily basis.
Daily supply of FDC, instead of thrice a week, has been introduced under the 99 DOTS (Directly Observed Treatment, Short-Course) scheme.
The scheme is called 99 DOTS because it has 99% chances of cure of the patients taking the medical course.
Under this initiative, medicines for 28 days will be given to the patient and there will be a tab on the consumption of the medicines. Patient medication is packaged envelopes with dosage instructions, and a series of hidden numbers behind the pills. Each time a patient takes a dose of medication, he will have to call on the number and if a call is not received at the centre, he is called on the registered mobile number to remind him about the dosage.
To determine the level of HIV infection among general population as well as HRGs in different states.
To understand the trends of HIV epidemic among general population as well as HRGs in different states.
To understand the geographical spread of HIV infection and to identify emerging pockets.
To provide information for prioritisation of programme resources and evaluation of programme impact.
To estimate HIV prevalence and HIV burden in the country.
