Abstract
HIV belongs to Lentivirus, which are also known as "slow virus". The name indicates there mode of action as they enters into body and remain in it for longer period of time. They have unique property of being inserting the information into the DNA of host cell and also have the ability to replicate in non-dividing cells. Two types of HIV has been characterized; HIV-1 and HIV-2. HIV-1 is the most virulent and pathogenic strain. Worldwide, the predominant virus is HIV-1, and generally when people refer to HIV without specifying the type of virus they will be referring to HIV-1. The basic aim of the study is to analyze the prevalence and reasons of growing epidemics of HIV/AIDS in a Pakistani population. This study was basically conducted in a Pakistani population by designing a questionnaire. This was done during 2017 to 2018 with the help of different hospitals and different other departments of universities and hospitals. Basically we design a questionnaire to find out the reasons and prevalence of HIV/AIDS in Pakistani nation. The prevalence of STDs is alarmingly high in Pakistan especially in male individuals. Currently, the STD rate in men in urban areas of Pakistan is estimated to be8.5% in Karachi, 5.3% in Lahore, 4.0% in Faisalabad, 4.3% in Quetta, 2.5% in Rawalpindi, and 2.0% in Peshawar. This is the common thought in the minds of Pakistani people that as an Islamic Republic, Pakistan is protected from HIV/AIDS. This is true that Islam is against pre-marital sex or extra-marital sex and also homosexuality, and this is a valuable barrier against HIV/AIDS. But still there is a threat of prevalence of this disease in Pakistan.
