STDs caused by bacteria or parasites can be treated with antibiotics. There’s no cure for STDs caused by viruses, but treatment can relieve symptoms and help keep the STD under control. For example, although there's no cure for HIV, ART can prevent HIV from advancing to AIDS.

Untreated STDs may lead to serious complications. For example, untreated gonorrhea in women can cause problems with pregnancy and infertility. Untreated HIV will eventually advance to AIDS and cause death.

I found a website that may help us to understand more about HIV and STD :

#Department of Health and Human Services: Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents

As the number of Asians in the United States continues to grow, health professionals are beginning notice obvious gaps of knowledge in caring for this population, including HIV-infected individuals. Little is known about the impact of religion and faith on Asian Americans with HIV and their families. The study focuses on the participants’ reported experiences to understand the variety of roles religion can play in the progression of a highly stigmatized chronic disease.

An in-depth interview was conducted in San Francisco and New York City with 30 HIV-infected Asians. Narrative samples and summarized responses was used to highlight themes that emerged from the participants’ anecdotes. Interpretive content analysis was employed. These groups were categorized as (a) those who did not adhere to any religion, (b) those of tenuous religious faith with conflicted feelings, and (c) those of strong religious faith with congruent beliefs. Within these three groups, various themes were synthesized from the members’ perceptions and past experiences with religion. Within each group, participants displayed various stages of reconciliation with their current faith-related beliefs and escape the family stress from their religion practices. Each participant’s story shown the vast range of human understanding and faith experiences including self-actualization, acculturation, and depression. This research provides new insight on the challenge of managing HIV-infected patients in a culturally and religiously appropriate manner.
