Epidemiology of HIV/ AIDS in India National AIDS Research Institute, Pune, India
Phases of spread of HIV epidemic in India Commonest mode of HIV spread in India is by sexual route Mother to child transmission is on the rise HIV spread among intravenous drug users mostly in north-eastern states Blood transfusion associated spread is on the decline
Factors related to HIV infection [STD clinic attendees in Pune] * Practice of sex work * No. of sex partners * Receptive anal sex * Females in sex work (FSW) * Men having sex with FSW recently * Lack of formal education * Persons living away from family * Previous / present STDs * Absence of circumcision
HIV/AIDS IN MANIPUR HIV was first detected in Manipur in 1989 among intravenous drug users, HIV prevalence >70% in drug users 75.2% knew that needle sharing could lead to acquisition of AIDS, however, needle sharing was practiced by 96.8% Drug users: predominantly male (94.8%), between 15 and 35 years (95.3%) Median duration of drug use: 5 years, No. of times heroin used: 1 – 14 per day SKB ICMR
AIDS Epidemiology • Modes of transmission Sexual 84.24% Perinatal 26.1% Blood 2.99% IDUs 2.83% Others 7.32%
Distribution in States • Maharashtra 10797 • Gujarat 2141 • Karnataka 1617 • Tamil Nadu 18276 • Andhra Pradesh 2565 • Manipur 1238 • Nagaland 298
High prevalent States States where HIV prevalence in antenatal women is 1% or more. Moderate prevalent States States where the HIV prevalence in antenatal women is less than 1% and prevalence in STD and other high risk groups is 5% or more. Low prevalent States States where the HIV prevalence in antenatal women is less than 1% and HIV prevalence among STD and other high-risk group is less than 5%.

HIV Prevalence Trend in India Prevalence New Infections 1998 3.5 m - 1999 3.7 m 0.2 m 2000 3.86 m 0.16 m • 3.97 m 0.11 m 2003 5.1m Inference : New infections are declining
Sentinel Surveillance for HIV Infection in pregnant women in Pune
Sentinel surveillance for HIV Infection in tuberculosis patients in Pune HIV seroprealence % Tuberculosis is the most likely presentation of AIDS in India
Molecular epidemiology HIV-1 C is the commonest prevalent subtype in India
Clinical conditions and CD4 counts * Oral candidiasis and weight loss were associated with and were highly predictive of low CD4 counts * Absence of clinical conditions were good predictors of high CD4 counts
