Reacting to the global reports of HIV/AIDS, Indian
Council of Medical Research (ICMR) initiated
surveillance for HIV infection in India in 1985-1986
and the first evidence of HIV infection in sex workers
in Chennai, Madurai and Vellore was obtained in
1986-19871,2. Gradually centers were established in
the State Capitals of India. National AIDS Control
Organization (NACO) set up under the Ministry of
Health and Family Welfare mandated to implement
initiatives like establishing HIV testing centers,
strengthening blood-safety and controlling hospital
infection took over surveillance activity in 19923. The
epidemiologic data on HIV/AIDS in India has emerged
primarily from the network of sentinel surveillance,
ongoing testing in antenatal clinics and blood banks,
research studies, reporting of AIDS cases and
information generated from mortality statistics. The
geographic distribution of the HIV epidemic in India
is varied and based on the prevalence of HIV
infection in the low and high risk groups, various

Since the first report of HIV infection in India in 1986, the virus has spread all over the country
although there is geographic variation. There are estimated 5.1 million people infected with
HIV with an overall estimated adult prevalence below 1 per cent. Surveys carried out in different
sub-populations have yielded prevalence estimates, but data on HIV incidence are limited. Both
HIV serotypes 1 and 2 exist in India and HIV-1 C is the commonest subtype reported. Sexual
transmission of HIV is most predominant. Spread of HIV in intravenous drug use settings is
localized mostly in the north eastern region and metropolitan cities and parent to child
transmission is on the rise.  Dual epidemics of HIV and tuberculosis, increase in the number of
infected women, stigma and discrimination are the main concerns in the Indian HIV/AIDS
scenario. There is an increasing political will and commitment for HIV prevention and control
efforts in India. A multi-disciplinary approach combining targeted interventions like early
identification and treatment of STDs, condom promotion, blood safety, drug de-addiction programs
and expanding and strengthening VCTCs and long-term strategies like awareness oriented to
behavioural change especially among vulnerable populations, young people and women, steps
towards improvement of literacy, status of women and overall development, reduction in poverty
and development of primary prevention interventions like vaccines and microbicides will have
to be considered for effective prevention and control of AIDS in India.

States have been categorized in high, medium and
low prevalence areas. Andhra Pradesh, Tamil Nadu,
Maharashtra, Karnataka, Goa and Manipur are
classified as high prevalence States with HIV
prevalence of over 1 per cent even in low-risk
populations4.
Urban and rural spread: Surveys carried out in
different sub-populations have yielded prevalence
estimates, but data on HIV incidence are limited.
Boxes 2 and 3 summarize the observed HIV
prevalence by risk categories in various geographic
areas in India. A large cohort study was initiated in
Pune in 1993 to estimate the prevalence and incidence
of HIV infection in persons with high risk behaviour.
Screening of 5321 sexually transmitted disease (STD)
patients during 1993-1995 provided a HIV-1
prevalence rate of 21.2 per cent5 and the first estimate
of HIV incidence of 10.2 per cent per year in a high-
risk population in India6. Although most of the initial
research was focused on high risk populations, some
community-based studies attempted to identify the
extent of spread in the community. A cluster survey
in three randomly selected urban and rural districts
of Tamil Nadu State among 1157 women and 824 men
(age 15-45 yr) from 1114 households reported that
the overall community prevalence of STDs, HIV and
hepatitis B infection was 14.6, 1.8 and 5.3 per cent
respectively7. This indicated that the STD and HIV
epidemics in Tamil Nadu had become generalized and
were not restricted to high risk populations. In
northern States of India, the HIV prevalence is
comparatively low. Among persons reporting to
Voluntary Counselling and Testing Centre (VCTC)
for AIDS in Rohtak (Haryana) during 1986-2002, 0.64
per cent (1178/183912) were HIV sero-positive
indicating a low prevalence over nearly 14 yr 8.
Studies have documented that the HIV epidemic has
reached rural areas of India. In a study on 1251
pregnant women in villages in three Primary Health
Centers in Pune district of Maharashtra, 15 (1.2%)
were detected to be HIV seropositive. The prevalence
was higher among the villages on the highways and
awareness about HIV/AIDS was found to be low9.
Increased mobility of individuals might be contributing
in dissemination of HIV infection from urban to rural

Box I. Some milestones of HIV/AIDS epidemic in India at a glance
1985-86 Indian Council of Medical Research (ICMR)initiated HIV surveillance at specified sites. First report of HIV infections
in sex workers in Chennai and first report of AIDS in Mumbai.
1989 HIV infection reported among intravenous drug users in Manipur State.
1990-91 National AIDS Control Organization (NACO) was established. Indian National AIDS Control Programme was launched.
1992 ICMR established National AIDS Research Institute (NARI) in Pune city.
1998-99 Majority of intravenous drug users investigated in Manipur were found to be HIV infected, sexual transmission to
partners of HIV infected drug users documented.
1999 The Supreme Court ruling made HIV testing of all  blood bottles mandatory. NACO estimated 3.87 million HIV infections
in 1998 in India.
2000-01 Feasibility studies for prevention of parent-to-child transmission of HIV with zidovudine and nevirapine were initiated
by NACO.
2001 Indian pharmaceutical companies marketed antiretroviral (ARV) drugs with considerable price reduction.

areas. Screening of the 2063 individuals in rural and
urban areas in south India revealed the HIV
prevalence to be 7.7 per cent10. Men move to urban
areas for work leaving their spouses behind to look
after their farms, the children and elderly; remain
away from their families for a long time and might
indulge in high-risk behaviour. The infected men carry
the infection back to their spouses in the rural areas.
Living away from the family has been reported to be
an independent predictor of HIV acquisition in men6.
The HIV epidemic has reached the general population
as suggested by data from metropolitan cities with
rates of HIV infection crossing 2 per cent in Mumbai,
>1 per cent in Hyderabad, Bangalore, Chennai and
<1 per cent in Kolkata, Ahmedabad and Delhi. The
community-based studies done in Tamil Nadu have
documented community prevalence of HIV to be 1.8
per cent11.
HIV - serotypes and subtypes: Both HIV serotypes
1 and 2 have been shown to exist in India. In western
India, HIV-2 and dual infections with HIV-1 and
HIV-2 have been reported since early nineties12-14
and in South India in late nineties10. However, in
Kolkata in eastern India, HIV-2 has been only recently
detected although HIV surveillance is being done since
198615. In addition to heteroduplex mobility assay
(HMA), peptide enzyme immunoassay (PEIA), and
DNA sequence analysis have been used for subtype
analysis16 and HIV-1 C has been the commonest
reported subtype in India. Other subtypes like A and
B have been found and some recombinants have also
been reported17-19.
Sexual transmission: Sexual behaviour as reflected
by more number of sexual partners, sex with sex
workers, being in sex work and receptive anal sex,
has been reported to be strongly associated with HIV
infection6,10,20. Risky sexual behaviour of mobile and
traveling populations has been linked to HIV infection.
A study among 263 truck drivers/assistants recruited
at a highway clinic in south India in 1999-2001
reported frequent female sex workers (FSW)
contacts, alcohol consumption, presence of various
STDs and high positivity rates of HIV, Venereal
Disease Research Laboratory (VDRL) reactivity and
HBsAg (15.9, 13.3 and 21.2% respectively)21. Poor
educational background has been often reported to
be linked to higher risk of STD and HIV
acquisition6,22. Low and inconsistent condom use and
genital ulcer disease or genital warts have been
associated with prevalent and incident HIV infection
in high risk populations like FSWs 12. Men tend to
have preferences in condom use as seen in a STD
patients’ cohort where condom usage by men with
sex workers increased over time, but over 70 per
cent of them  continued to have sex with their
spouses without condoms even in presence of active
STDs23. Married women do not have adequate
understanding or perception of risk of STD/HIV
from their spouses24.
Few studies have been done on men having sex
with men (MSM). In a cross-sectional population-
based random sample survey in 200125, 774 randomly
selected residents of 30 slums in Chennai were
interviewed for behavioural risk factors and 46
(5.9%) of them reported sex with other men. MSM
were 8 times more likely to be seropositive for HIV
and over twice more likely to have a history of STD
than non-MSM. Risk behaviour assessment of 10,785
men attending 3 STI clinics in Pune from 1993 to 2002
indicated that 708 (6.6%) were MSM. Hence specific
interventions targeting MSM should also be included
in the control of HIV and STDs26.
Certain biological factors like age, STDs and
circumcision have been reported to be significant in
sexual transmission of HIV. In a study of 1872 male
STD patients seen during 1998-200027, risky sexual
behaviour like early initiation of sex, premarital sex
and bisexual orientation was common in younger men.
Such evidence highlights the need for introducing
targeted interventions among adolescents27. Past high
risk behaviour (history of STDs or VDRL
reactivity)10,12  and present risk behaviour (presence
of active STD) have been associated with high HIV
prevalence as well as HIV transmission6. In a cohort
of HIV-1-seronegative patients attending STD clinics
in Pune28, the incidences of herpes simplex virus 2
(HSV-2) and HIV-1 were and 5.8 cases/100 person-
years respectively. Recent incident HSV-2 infection
was found to be associated with the highest risk of
HIV-1 infection28. This suggests that prevention and
effective treatment of STDs including HSV-2
infection might reduce the risk of HIV-1 acquisition
359
considerably6,28. Circumcision has been reported to
be protective against STDs and HIV 29,30. In a
prospective study of 2298 HIV-uninfected STD
patients in Pune, India31, circumcision was found to
be strongly protective against HIV-1 infection but not
against herpes simplex virus type 2, syphilis or
gonorrhea. Thus, the protective effect of male
circumcision could be primarily due to biological rather
than behavioural reasons. With majority of the male
population being uncircumcised, it is important to
stress penile hygiene and condom use in the context
of prevention of sexual transmission of HIV in India.
Transmission in couples: In a study among women
attending STD clinics in Pune from 1993 to 199632,
prevalence of HIV infection was observed to be 49.9
per cent in FSWs and 13.6 per cent in those who
were not sex workers with majority reporting single
sexual partner. This was the first evidence of a high
HIV prevalence in married monogamous women in
India with a strong suggestion of risk from their
husbands32. Similarly sexual partners of intravenous
drug users (IDUs) in Manipur in north east India have
been shown to have a high risk of HIV infection 33. A
study among STD patients in a district hospital in
Maharashtra state documented difficulties and
deficiencies in communication with regular sexual
partners on sexual matters34. Specific strategies need
to be considered for improving sexual communication
and negotiation of safe sex in couple settings. In the
first couples’ cohort study in India, 242 HIV sero-
discordant couples were enrolled in 2002-2003 and
the incidence of HIV infection was observed to be
1.97 per cent per year35, much lower compared to
that reported in Africa36,37.
Parent to child transmission: Consequent to spread
of HIV in women there is a potential for perinatal
HIV transmission resulting in paediatric HIV
epidemic. Studies from India38,39 documented mother-
to-infant HIV transmission rates between 36 and 48
per cent. It has been reported that 63 per cent of the
multi-transposed thalassaemic HIV infected children
became symptomatic in infancy with a 9 per cent
fatality rate within 14 months of age40. Another study
reported median survival of 8.5 months (range: 0.3-
2 yr) in 26.3 per cent perinatally infected children41.
Hence, prevention of perinatal HIV infections is
important. In Mumbai, in a non-randomized study, an
intervention involving administration of zidovudine
(AZT) for the last 6 wk of the pregnancy, delivery by
elective caesarian section, oral AZT administration
to the infant and avoidance of breast-feeding resulted
in 5.9 per cent transmission rate compared to 24 per
cent in the non-intervention arm42. NACO instituted
a multi-site study in 11 institutions selected from the
5 high prevalence States in India to assess the
feasibility of administration of AZT in pregnant women
to reduce mother-to-child transmission of HIV
infection43. Acceptability of AZT prophylaxis among
pregnant women in this study was 43.6 and 22 per
cent of the women opted for breast-feeding at birth.
Subsequently NACO also undertook feasibility study
of one dose nevirapine for the prevention of parent-
to-child transmission of HIV. The results of both these
studies would provide guidelines while deciding
strategies for scaling up efforts to prevent parent-
to-child spread of HIV.
Transmission of HIV in injecting drug users :
Although injecting drug use is known to be prevalent
in many major cities of India, the problem of HIV
has been investigated in the north-eastern States and
in cities like Chennai, Kolkata and Delhi. The
prevalence of HIV infection among injecting drug
users in Manipur State increased rapidly from
2-3 per cent in 1989 to over 50 per cent in 1991 44 and
has been estimated to be above 75 per cent at present.
Majority of the injecting drug users in Manipur;
primarily young males, using drugs for a median of
five years, in spite of high level of awareness about
the possibility of HIV transmission through sharing
of needles routinely share injecting equipment. A
study among women in Manipur45 in 1997 revealed a
high HIV prevalence of 57 per cent among drug users
compared to 20 per cent among non-injecting drug
users. Majority of them also had genital discharge
disease45. A study in Chennai also reported multiple
risk behaviours like exchanging money for sex or
having sex with men among men who used illicit
drugs25. Thus, in addition to prevention of parenteral
transmission through measures like reducing availability
of drugs, de-addiction programmes, education for safe
injecting practices and providing clean needles;
prevention of sexual transmission also needs to be
focused in the drug use settings.

Transfusion associated AIDS: Various studies have
reported a gradual increase of HIV prevalence in
blood donors over the last two decades and this
observation generally reflects the trends seen in the
sentinel surveillance. In replacement donors in New
Delhi, HIV prevalence increased from 0 in 1991 to
0.06 per cent in 199746. A five year study (1994-1999)
among 46,957 donors in north-western India reported
overall HIV prevalence of 0.44 per cent, more in
replacement (0.461%) as compared to voluntary
(0.279%) donors47. Between 1993 and 1996, 1.81 per
cent of the 12,235 replacement blood donors in
Mumbai were found to be seropositive for antibodies
to HIV types 1 and 214. Prevalence of HIV infection
among non-professional blood donors at the Christian
Medical College and Hospital, Vellore increased from
1.6 per 1000 in 1988-1989 to 3.8 per 1000 in 1996-
199748. Majority of the blood donors are normally
healthy adult males and HIV prevalence of over 2-3
per cent in replacement blood donors could be
indicative of generalization of the epidemic in the
country. It is important to promote voluntary donor
movement to ensure that the donors are free from
transfusion transmissible infections like hepatitis B
and C, HIV-1 and HIV-2, syphilis and malarial
parasites. The first cases of paediatric AIDS in India
were reported in multitransfused thallasaemic
children, in two different studies from Delhi and
Manipur, showing the same HIV prevalence of 8.9
per cent40,49. Although transfusion associated AIDS
contributed significantly to the total HIV disease
burden in India in the late 1980s to early 1990s, this
proportion rapidly fell thereafter.
HIV disease burden in India: There has always been
some controversy around this issue in India. The
estimates of the Indian Government and the United
Nations agencies have always been at variance.
NACO has based its estimations on the sentinel
surveillance system in specific high and low risk
groups and generated point estimates of 3.50, 3.70
and 3.86 million for the years 1998, 1999 and 2000,
respectively. Considering that all risk groups were not
adequately represented in these estimations and that
AIDS cases were not included in this exercise, a
20 per cent range was applied and the upper bounds
were taken as working estimates for the country4,50.
Subsequently, exercises were employed for validating
community based STD prevalence in rural and urban
areas. Additionally Behavioural Sentinel Surveillance
data of 200151 and HIV Sentinel Surveillance data
from urban and rural subsets were used for HIV
burden estimation in 2003. As of October 2003, an
estimate of 5.1 million was provided by NACO with
an overall adult prevalence below 1 per cent (59.9%
of all infections in the rural areas and 61.75% in the
high prevalent states)52. For the year 2004, annual
round of sentinel surveillance has been planned at
670 sites, inclusive of 124 rural sites in high prevalence
States and relocation of 18 STD sites in private sector
hospitals in order to ensure participation of private
sector STD clinics.
Some studies were done to estimate the actual
burden of HIV disease and economic impact on the
society. A study in Mumbai estimated 85,200
individuals to be HIV infected in 1997 and at least
4120 excess deaths due to AIDS53. A study in Pune54
used micro level estimates and documented that
district level disease burden estimates (in DALYs per
1000) based on locally generated data were higher
than the Global Burden of Disease estimates for India.
The community prevalence in Pune district for 2000
was estimated to be 1.28 per cent, with at least 5729
persons qualifying for antiretroviral therapy54. A
simplistic model of two scenarios with and without
HIV/AIDS and steady state population demographics
and life table approach estimated life years lost per
case of HIV infection to be 44.4 yr with a total
economic loss of Rs.1014 billion in 1997 in India 55. It
is important to have well-set surveillance network
with wide and uniform coverage, reliable community-
based incidence and prevalence data on HIV and
STDs and mortality data due to AIDS as well as HIV
related illnesses for realistic estimation of HIV
disease burden in the country.
Consolidating the national response for
prevention and control
When HIV infection was discovered in India in
1986, the health authorities set up the NACO which
prepared an outline for National AIDS Control
Programme (NACP)54 that was primarily funded by
the World Bank and technically supported by WHO.
NACP operates with a multi-directional approach

and various strategies include blood safety, condom
distribution, control of STDs, surveillance
and information-education-communication.
Nongovernmental and community based organizations
are also active in the area of HIV prevention.
Improvements in programme management and
application of appropriate interventions have
documented successes. The Supreme Court of India
banned paid donations by the end of 1997 and
autonomous National Blood Transfusion Council and
the State Transfusion Councils were established.
Attempts are ongoing to improve the transfusion
service in India. There has been a considerable decline
in transfusion associated HIV transmission and
change over to voluntary donor service would further
reduce this number. National efforts are ongoing in
this direction57. Prevention of perinatal transmission
of HIV is one of the few success stories in HIV
prevention research. With the reduction in the cost of
ART drugs and demonstration of ability to introduce
HIV testing and chemotherapeutic intervention among
the pregnant women in the feasibility studies of AZT
and nevirapine by NACO43, it is likely that this
intervention will be made available for countrywide
application as a part of the national programme soon.
The programme to offer antenatal counselling, testing,
and antiretroviral treatment to prevent mother-to-child
transmission has already been expanded to 225
antenatal clinics, and is the largest national antenatal
screening programme in the world58. By enhancing
access to treatment and through interventions like
counselling, education, and provision of condoms for
prevention of STDs, especially genital ulcer disease,
among disadvantaged men, the disparity in rates of
HIV incidence could be lessened considerably 22.
Interventions in MSM in Chennai slums suggested
that HIV prevention strategies aimed at changing
unsafe drug and sexual practices should target the
general population of men rather than giving specific
attention to areas with high rates of MSM25.
During the beginning of the African epidemic,
Uganda faced a severe crisis, with almost 30 per cent
of the adult population infected with HIV/AIDS in
1980s and 1990s. Uganda responded through a mix
of rationalist and creative policy approaches and after
a decade of intervention a decline in HIV prevalence
was noted59. Similarly, with limited resources the
national programme for preventing mother-to-child
HIV transmission in Thailand was successful due to
focusing attention on counselling, communication,
training and focused monitoring in the programme60
and a behavioural intervention comprising of
consistent condom use, reducing alcohol consumption
and brothel patronage improving sexual negotiation
and condom skills among conscripts in the Royal Thai
Army for 15 months substantially reduced the risk of
incident STI and HIV61.
There is an increasing political will and
commitment to HIV prevention and control efforts in
India. A recently constituted National Parliamentarian
Forum has stressed support for additional HIV
prevention programmes including a large school-based
adolescent education programme and a national
campaign to raise awareness about STDs and
treatments. The annual budget for the NACP has
doubled over the past 3 yr58. Antiretroviral drugs are
manufactured in the country and exported elsewhere,
but their affordability to a common man (despite a
drastic reduction in costs) and technical difficulties
in creating facilities for monitoring for adverse
reactions and resistance are in question. A recently
started programme of Government of India to provide
highly-active antiretroviral therapy (HAART) to
100,000 HIV infected patients in six high HIV
prevalent states in India indicates the commitment to
the cause of those who are living with HIV infection62.
The Government of India has strengthened the
collaboration between TB and AIDS control
programmes for better management of dual HIV-TB
epidemic and regions with higher prevalence of HIV
infection have been prioritized for the Revised
National TB Control Program (RNTCP) focusing on
directly observed therapy-short course (DOTS)
coverage63.
Meeting the challenge
Evidence indicates that trajectory of the HIV
epidemic in India is distinct from some African
countries58. However, there is no justification for
complacency and the focus of HIV prevention in India
should be on evidence based intervention among
vulnerable communities, enhancing access to care and
GODBOLE & MEHENDALE: TWO DECADES OF HIV EPIDEMIC IN INDIA
364 INDIAN J MED RES, APRIL  2005
treatment for people living with HIV/AIDS and
decentralization of the programme financially and
operationally by supporting States and districts to
develop critical capacities64,65. There appears to be a
need for an integrated and all-inclusive approach than
a compartmental AIDS prevention centered
approach. Close co-ordination between the
governmental, non governmental, international and
community-based organizations in implementation of
intervention programmes may prove to be cost-
effective and cost-efficient60.
The dual epidemic of HIV and tuberculosis is a
cause for concern in India where these two infections
are prevalent in epidemic proportions. The
seroprevalence of HIV among tuberculosis patients
in various parts of India has been increasing steadily66.
Among newly diagnosed tuberculosis patients in Pune,
the overall seroprevalence of HIV infection increased
from 3.2 per cent in 1991 to 20.1 per cent in 1996 67.
It is expected that HIV will increase the number of
TB cases in India by at least 10 per cent and by a
considerably higher percentage if HIV becomes much
more widespread. In India, TB is the indicator disease
for HIV infection and most often the first AIDS-
defining disease. The risk of development of TB in
HIV infected patients in India has been estimated to
be nearly 7 per 100 person-years63. Though primary
and acquired multi-drug resistant tuberculosis in India
is a major likely threat, it is still not a major public
health concern68,69. There are challenges in the
management of dual infections due to HIV and TB
and clinicians will have to be trained adequately.
India’s experience shows that DOTS can achieve high
cure rates70, however, its effectiveness needs to be
critically evaluated on the background of ongoing HIV
epidemic.
Sexually transmitted infections play a significant
role in HIV transmission and acquisition. A significant
increase in the number of viral STDs and a decline in
the bacterial diseases have been observed in recent
years71. Whether the observed decline is a real
phenomenon due to higher awareness of HIV/AIDS,
success of control programme and syndromic
management of STDs71 or this population has got
diverted to unqualified persons and self-treatment by
across-the-counter purchase of drugs to avoid HIV
testing needs to be investigated. So is the need to
capture qualified health care providers in the private
sector in the programme and address the issue of
unqualified workers' needs.
Estimating disease burden in a community is always
a challenge. In view of the limitations of the traditional
cohort method of estimating incidence which is
important for estimating disease burden, novel
approaches of incidence estimation such as using
mathematical models based on cross-sectional
surveys72 or a multi-stage pooling method to detect
RNA-positive pools and then re-analyzing smaller
pools73, or detuned ELISA tests may have to be tried.
Planning is currently underway to estimate the disease
burden of HIV infection in India because this is crucial
for strategic planning for programme implementation.
HIV infected persons have repeatedly voiced their
right to live with dignity. They experience
discrimination from the health care workers due to
inadequate knowledge and unduly high perception of
occupational risk. Training of health care workers
thus becomes a major priority. It is important to equip
us with adequate and appropriate facilities for
inpatient and outpatient care of HIV infected people
with a focus on providing access to primary care and
home-based care.
A large number of women in India are affected
with no risk behaviour of their own. Community
gender norms have a sanction for domestic violence
that interferes while adopting and negotiating HIV-
preventive behaviours by women. Given the choice
between the immediate threat of violence and the
relatively hypothetical threat of HIV, women often
resign themselves to sexual demands and indiscretions
that may increase their risk of HIV acquisition74. It is
therefore important to be sensitive about gender-
related issues while designing strategies and
interventions for AIDS prevention. Young women are
often detected as HIV infected during their first
pregnancy, majority of them within the first two years
of marriage. Due to social and family pressures girls
agree to early and “timely” marriages, because
delayed wedding among girls carries social stigma
and young males often aware of their risk behaviour
and possibly also of their HIV status cannot remain
365
single. In India, HIV-related counselling services are
still not readily available. Systematic efforts to
eliminate stigma should be continued and
establishments of voluntary counselling and testing
centers (VCTCs) at the district level are expected to
play a major role in this direction.
Though like many other developing countries, the
main barriers to effective control of AIDS are
reported to be insufficient resources, illiteracy, and
stigma, there is a need to assess if the prevention
and control efforts are directed to the right populations
and if appropriate programmes are in place and are
working optimally. AIDS is less of a medical problem,
but more of a social, cultural and developmental
problem. Thus, there is probably not going to be an
easy solution. Short-term strategies like aggressive
case detection and management of STDs, condom
promotion, blood safety and drug de-addiction
programmes might yield quick results.  However, they
should be effectively complemented by a multi-
disciplinary approach and long-term strategies for
HIV prevention and control. These include steps
towards removing social injustice and inequity,
improving economy and achieving overall
development, efforts to increase the status of women
in the community and development of safe and
effective primary prevention interventions like
vaccine or vaginal microbicides.
