5. HIV/AIDS: Basic Concept
Acquired immuno-deficiency syndrome is a
fatal disease caused by the human immuno-
deficiency virus (a retro virus)
Sometimes it is called Slim disease
Termed as modern pandemic
No effective treatment & vaccine is available
To combat HIV/AIDS is a MDG (MDG-6)
Regarded as social & developmental problem
8. History of HIV/AIDS
1981: First case of AIDS identified in Los
Angeles but was named as AIDS in 1984.
1982-85: Rapid spread in western Europe and
Australia.
1983: Virus identified at Pasteur institute but
named HIV in 1986.
1984: Antibody detection test discovered.
1984: First HIV positive in Asia identified.

Per-enteral: Through infected Blood/blood
products (tissues and organs transplantation)
Per-enteral: Through contaminated needles,
syringes, medical utensils and other piercing

• HIV+ Cases 370 3241
• AIDS Cases 95 1299
• AIDS Death 82 472
Source: NASP Publication, 1 December 2013
36. Geographic proximity to highly prevalent
neighboring countries like India, Thailand &
Myanmar and air and water routes with the world
High prevalence of STDs
High levels of unprotected sex by CSWs
High rate of needle sharing among IDUs
Limited correct knowledge on HIV/AIDS
Large number of STD cases

Factors Making Bangladesh a
High Risk Country
37. Low condom use among the MARP and the
bridging population.
Low level of voluntary blood donation.
External and internal migration.
Subordinate status of women.
Violence against women.
Unequal access to health care services.
Legal laws and human rights.
Factors Making Bangladesh a
High Risk Country
38. Symptoms of AIDS
Major Symptoms:
Loss of weight by more than 10% during last 6 months

39. A two months old infant born to a mother with AIDS. The child
developed pneumonia and oral candidiasis
40. The child was first seen
at the age of 9 months
for recurrent diarrhoea,
otitis media and failure to
thrive. He was marasmic
and had generalised
lymphadenopathy, and
hepatosplenomegaly.
Chest x-ray showed
evidence of pulmonary
tuberculosis. HIV tests in
mother, baby and the
father were positive.
41. WOMEN ARE ESPECIALLY
VULNERABLE TO HIV/AIDS
Biologically vulnerable
to infection
Sexual exploitation
including trafficking
Inability to refuse sex /
negotiate safer sex
Violence against women
Migration
Poverty
42. Young people and HIV
Sexual experimentation
(40% male adolescents go to CSWs and
80% of them do not use condom)
Many are Drug users
Low awareness level on HIV
prevention
Vulnerability in the workplace
Street children (Forced sex)
Nearly half of new HIV infections occur
to young people below the age of 24
43. Key National Responses of GOB…
1985: National AIDS Committee(NAC) was
formed.
Formation of TC of NAC & 2 sub-committees:
Monitoring sub-committee (MSC) & Motivation
cum Publicity sub-Committee (MPSC).
1987: GOB started AIDS Prevention activities.
1988: 5 HIV diagnostic laboratory established.
1989: 3-year Medium Term Plan was formulated.

44. 1994-1996: UNDP supported the HIV/AIDS
Intervention.
1997: The National Policy on HIV/AIDS and
STD Related Issues was approved by the
cabinet.
1997: A five-year National Strategy (1997-
2002) adopted in NAC for effective launching
of HIV/AIDS Interventions.
1998-2005: Six Behavioral and Serological
Surveillance BSS on HIV and Syphilis was
completed.
Key National Responses of
GOB…
45. 1998:NASP management structure outlined,
activities being carried out by three main
functionaries : the NAC, MOHFW & DGHS.
1998-2000: UNDP supported Multi-sectoral
AIDS Prevention Project (MAPP).
2002: Laws on blood safety passed by the
parliament (98 blood screening centers
established; screening HIV, Syphilis,
Malaria, HBV & HCV).
2004-2010: A National Strategic Plan on
HIV/AIDS formulated & implemented.
Key National Responses of
GOB…
46. NASP has developed
National ART guideline.
National STI management Guideline.
National harm reduction strategy for IDUs.
Safer sex promotion strategy in work place.
Guideline for clinical management.
Safe blood transfusion program.
National Sero & Behavioral Surveillance.
Mutisectoral involvement of NGOs, Donor, Civil society.
Human Rights issues for PLWHA.
Stigma & discrimination prevention.
Contribution of NASP
47. Levels of Prevention of HIV/AIDS
It needs all levels of prevention
Primordial Prevention
Primary Prevention
Secondary Prevention
Tertiary Prevention
50. Primary Prevention..
4 ‘S’ should be followed
Safe sex to practice (ABC)
Safe blood to transfuse
Safe injection to use
Safe Pregnancy to ensure
51. Vaccination
First clinical trial of Phase I of HIV
vaccination took place in 1987 in USA.
Phase II trial took place in Africa.
One large scale of Phase III trial is
currently undergoing in Thailand.
Scientists all over the world are trying
very hard for it.
53. Diagnosis of HIV/AIDS
Diagnosis is done by:
History
Clinical feature (major & minor) and
Specific laboratory investigations
HIV enzyme immunoassay
Western blot assay, detect HIV
antibodies in serum, plasma, oral fluid,
dried blood spot or urine of patient
54. Treatment
Antiretrovirals are not a permanent cure,
but it reduces the viral load and extends
the life of people living with HIV.
UNAIDS declared the lack of treatment
in low and middle income countries is a
global public health emergency.
55. Management of HIV/AIDS
Clinical Stage-1 (Asymptomatic): HIV is not
categorized as AIDS.
Clinical Stage-2 (Mild disease): Includes minor
mucocutaneous manifestations and recurrent
upper respiratory tract infections.
Clinical Stage-3 (Moderate disease): Includes
unexplained chronic diarrhea for longer than a
month, severe bacterial infections and pulmonary
tuberculosis.
Clinical Stage-4 (Severe disease): Includes
toxoplasmosis of the brain, candidiasis of the
esophagus, trachea, bronchi or lungs and Kaposi's
sarcoma; these diseases are indicators of AIDS.
56. General Management Measures
Bed Rest
Ensure adequate nutrition and fluid & electrolyte
balance
Provide proper nursing care and counseling
Maintain personal & oral hygiene
Symptomatic management of fever, pain, itching etc
O2 inhalation SOS
Catheterization SOS
Changing posture & oropharyngeal suctions SOS
Supplementation of vitamins and minerals
60. World AIDS Campaign
Brings diverse global voices on HIV/AIDS
together through a collaborative approach.
Holds world leaders & governments to
account for their promises on AIDS.
Share global actions and awareness on
HIV/AIDS.
“Stop AIDS Keep The Promise” (2006).
Universal Access and Human Rights (2010).
61.
62. Why Leadership?
All our efforts are not delivering at the
speed & scale required.
Promises are not being kept due to
Lack of leadership at all level.
Despite efforts to hold leaders
accountable, progress in halting HIV is
still falling far short of targets.
63. Why Leadership?
It acts as a vehicle for uniting efforts within a
common global message.
To maximize national, regional and
international visibility of global campaigning
efforts on AIDS.
It can promote a wide range of AIDS issues
globally.
It brings media, governments, businesses
and a range of institutions locally and
globally to embrace common issues on
HIV/AIDS.
64. Message for All
ABCD – 4 Basic rules of HIV Prevention
D-No to drugs
C-Use condom
B- Be faithful /Transfuse safe blood
A- Abstinence
65. Recommendations
Prevention of sexual transmission
Prevention of mother-to child transmission
Prevention of transmission through injecting
drug use, including harm-reduction measures
Ensure safety of blood supply
Prevention of transmission in health facilities
Promote greater access to voluntary HIV
counseling and testing while principles of
confidentiality and consent are followed
66. Integrate HIV prevention and AIDS
treatment into existing healthcare services.
Focus on HIV prevention among young
people
Provide HIV related IEC to enable
individuals to protect themselves from
infection.
Confront and mitigate HIV related stigma
and discrimination.
Prepare for access and use of vaccines and
microbicides
Recommendations
67. Firstly, Formulating the national
HIV/AIDS communication strategy.
Secondly, concentrating on groups
most vulnerable to the infection.
Thirdly, working with the general
population (community mobilization
and community participation).
Fourthly, care and support to those
already infected and affected by
HIV/AIDS (voluntary counseling).
Recommendations
68. Ray of Hopes…
Epidemics of HIV/AIDS is declining
Prevalence of HIV/AIDS has
decreases by 20% in last 20 years
Death rate due to HIV/AIDS has
reduced by 20% by last 5 years
(Report: UNDIDS, 22nd Anniversary,
World AIDS Day, 2010)
69. Ensure Universal access and human rights
in terms of prevention, promotion, health
care, access to opportunities, employment
and social affairs.
Use effective leadership at all levels both
nationally and globally to make Bangladesh
HIV/AIDS free.
