Abstract: The present study was an effort to know the AIDS knowledge and Information needs of the adolescent girls of Jammu. Sample was selected from the two Government and two Private institutions. The research was an attempt to study the knowledge level and information needs regarding HIV/AIDS among adolescent girls. The sample comprised of 100 respondents from the East Zone of Jammu City. Systematic random sampling technique was adopted. The tool used for obtaining information was close-ended questionnaire. The findings revealed that there was significant difference regarding knowledge level of HIV/AIDS between respondents of government and private school. Private school respondents had better knowledge as compare to their counter parts. Government School sample lack general knowledge regarding HIV/AIDS and related issues. Majority of the respondents from both the categories had knowledge about affected section and affected age group of society but were ignorant about the most vulnerable group and the level of risk for adolescents. A lot more still needs to be done for combating a campaign against this devastating disease. Political parties, religious leaders and NGOs should join hand for this purpose. The psychologists are also of the view that teaching alone will not solve the problem unless the programmes are framed according to the situation on correcting vicious behaviors like injecting drugs, indulging in heterosexual activity, homo sexuality etc. which would help in decreasing the number in the long run.
