Understanding and Preventing STDs and HIV/AIDS in India

Sexually transmitted diseases (STDs) and HIV/AIDS remain significant public health challenges in India. While substantial progress has been made in controlling these infections, they continue to affect millions of people and require ongoing awareness, prevention, and treatment efforts. Understanding how these infections spread, recognizing their symptoms, and knowing how to prevent them is essential knowledge for healthcare professionals and the general public alike.

What are sexually transmitted diseases? 🔗

Sexually transmitted diseases (STDs), also called sexually transmitted infections (STIs), are infections primarily spread through sexual contact including vaginal, anal, and oral sex. According to the WHO, more than 30 different bacteria, viruses, and parasites can be transmitted through sexual contact. Some STIs can also spread through mother-to-child transmission during pregnancy, childbirth, and breastfeeding, as well as through contaminated blood transfusions.

Eight pathogens account for the greatest burden of STIs globally. Four of these are currently curable: syphilis, gonorrhoea, chlamydia, and trichomoniasis. The other four are viral infections that can be managed but not cured: hepatitis B, herpes simplex virus (HSV), HIV, and human papillomavirus (HPV).

Common types of STDs 🔗

Bacterial STDs include chlamydia, gonorrhoea, and syphilis. Chlamydia, caused by the bacteria Chlamydia trachomatis, is one of the most common STIs and often presents without symptoms. If untreated, it can lead to pelvic inflammatory disease and infertility in women. Gonorrhoea, caused by Neisseria gonorrhoeae, can affect the reproductive tract, throat, eyes, and rectum.

Viral STDs include genital herpes (caused by herpes simplex virus), HPV (which can cause genital warts and cervical cancer), hepatitis B, and HIV. Unlike bacterial infections, viral STDs cannot be completely cured but can be managed with medications.

Parasitic STDs include trichomoniasis, caused by the parasite Trichomonas vaginalis, which is treatable with appropriate medication.

Symptoms and complications 🔗

STDs often present without noticeable symptoms, making regular screening crucial for sexually active individuals. When symptoms do occur, they may include unusual discharge, painful urination, genital sores or ulcers, and pelvic pain. The WHO notes that gonorrhoea and chlamydia are major causes of pelvic inflammatory disease and infertility in women. Mother-to-child transmission of STIs can result in stillbirth, neonatal death, low birth weight, and congenital deformities.

Understanding HIV/AIDS 🔗

Human Immunodeficiency Virus (HIV) attacks the body’s immune system, specifically the CD4 cells (T cells) that help fight infections. Without treatment, HIV gradually destroys these cells, weakening the immune system and making the body vulnerable to opportunistic infections and certain cancers. The most advanced stage of HIV infection is Acquired Immunodeficiency Syndrome (AIDS).

Transmission of HIV 🔗

According to WHO India, the most common route of HIV transmission in India is unprotected sexual intercourse with an infected person. This is followed by mother-to-child transmission during pregnancy, childbirth, and breastfeeding, sharing of contaminated needles among injecting drug users, and transfusion of contaminated blood.

HIV cannot spread through casual contact such as hugging, shaking hands, sharing food or water, or through mosquito bites. Understanding these facts helps reduce the stigma associated with the infection.

Stages of HIV infection 🔗

HIV infection progresses through three stages if left untreated. The acute infection stage occurs within 2-4 weeks after infection, during which people may experience flu-like symptoms. The clinical latency stage (chronic HIV infection) may last for years, during which the virus reproduces at very low levels. Without treatment, this eventually progresses to AIDS, the most severe stage where the immune system is badly damaged.

HIV/AIDS situation in India 🔗

India has the third-largest population of people living with HIV/AIDS globally, after South Africa and Nigeria. The National AIDS Control Organisation (NACO) estimated that approximately 3.14 million people were living with HIV in India in 2023. However, the adult HIV prevalence rate remains relatively low at around 0.39%, reflecting the country’s large population base.

The epidemic in India is concentrated among specific high-risk groups including female sex workers, men who have sex with men, people who inject drugs, and transgender individuals. Studies show that HIV prevalence in these key populations ranges from 2.2% among female sex workers to 9.9% among people who inject drugs, significantly higher than the general population.

Significant progress has been made in recent decades. According to government data, new infections in India in 2023 were almost 44% lower than in 2010, while AIDS-related deaths declined by 79% during the same period.

National AIDS Control Programme (NACP) 🔗

India’s National AIDS Control Programme, implemented by the National AIDS Control Organisation under the Ministry of Health and Family Welfare, is one of the largest HIV/AIDS control programmes in the world. The programme was established in 1992 and has evolved through multiple phases.

Evolution of NACP 🔗

NACP Phase I (1992-1999) focused on creating awareness about HIV/AIDS and ensuring blood safety. This phase established the foundation for India’s response to the epidemic.

NACP Phase II (1999-2007) expanded prevention efforts by introducing direct interventions. This phase saw the development of the prevention of mother-to-child transmission programme (PMTCT) and the provision of antiretroviral treatment.

NACP Phase III (2007-2012) dramatically increased targeted interventions with the aim of halting and reversing the epidemic. This phase significantly scaled up HIV testing and treatment services.

NACP Phase IV (2012-2017) aimed to reduce new HIV infections by 50% and provide comprehensive care to all people living with HIV. The programme focused on consolidating gains and accelerating reversal of the epidemic.

NACP Phase V (2021-2026) is currently ongoing with the vision of achieving the global target of ending AIDS as a public health threat by 2030. The programme follows the “Three Zeros” goals: zero new infections, zero AIDS-related deaths, and zero discrimination.

Key achievements 🔗

Under the NACP, a network of over 18,000 integrated counselling and testing centres has been established across the country. The programme provides free antiretroviral therapy (ART) through hundreds of ART centres nationwide. NACO emphasizes that ART effectively suppresses viral replication, restores the immune system, and reduces chances of opportunistic infections when taken consistently.

Prevention strategies 🔗

Prevention remains the cornerstone of controlling STDs and HIV/AIDS. Multiple strategies work together to reduce transmission and protect individuals.

Safe sexual practices 🔗

The WHO states that when used correctly and consistently, condoms offer one of the most effective methods of protection against STIs, including HIV. While highly effective, condoms do not provide complete protection for STIs that cause extra-genital ulcers such as syphilis or genital herpes.

Regular screening and early treatment 🔗

Since many STIs are asymptomatic, regular testing is crucial for sexually active individuals. Early detection enables prompt treatment, preventing complications and reducing transmission to partners. Partner notification and treatment is an essential component of STI management.

Vaccination 🔗

Safe and effective vaccines are available for hepatitis B and HPV. These vaccines represent major advances in STI prevention. HPV vaccination, combined with cervical screening, is crucial for eliminating cervical cancer as a public health problem.

Prevention of mother-to-child transmission 🔗

HIV-positive pregnant women can significantly reduce the risk of transmitting HIV to their babies through antiretroviral therapy during pregnancy, safe delivery practices, and appropriate infant feeding counselling. India’s PMTCT programme ensures that HIV-positive pregnant women receive appropriate interventions.

Harm reduction for injecting drug users 🔗

Needle and syringe exchange programmes, along with oral substitution therapy, help reduce HIV transmission among people who inject drugs. These harm reduction strategies are integral components of India’s targeted intervention programmes.

Treatment options 🔗

Treatment approaches differ based on whether the STD is bacterial, viral, or parasitic in origin.

Treatment for bacterial and parasitic STDs 🔗

According to the WHO, three bacterial STIs (chlamydia, gonorrhoea, and syphilis) and one parasitic STI (trichomoniasis) are generally curable with existing single-dose antibiotic regimens. However, antimicrobial resistance, particularly in gonorrhoea, has increased rapidly in recent years and poses a significant threat to treatment options.

Antiretroviral therapy for HIV 🔗

NACO states that HIV infection is not the end of life, and people can lead healthy lives for a long time with appropriate medical care. Antiretroviral therapy effectively suppresses viral replication, restores the immune system, and enhances both quality of life and longevity. India adopted the “Treat All” policy in 2017, providing ART to all people living with HIV regardless of CD4 count.

Research indicates that early initiation of ART improves outcomes for people with HIV, decreases transmission, and is cost-effective. Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are also available for high-risk individuals to prevent HIV acquisition.

Addressing stigma and discrimination 🔗

Stigma and discrimination remain significant barriers to HIV prevention and treatment. The HIV/AIDS (Prevention and Control) Act 2017 was enacted to end stigma and discrimination against HIV-positive persons in workplaces, hospitals, and society while ensuring patient privacy. Creating supportive environments encourages people to get tested, seek treatment, and adhere to therapy.

Public awareness and education 🔗

Awareness campaigns play a crucial role in prevention. NACO’s Intensified IEC Campaign has successfully engaged health workers, community members, and youth in raising awareness and reducing stigma. The campaign involves various stakeholders including state leaderships, social influencers, and community organizations.

What do you think? How can healthcare professionals better address the stigma surrounding STDs and HIV/AIDS in their communities? What role can nursing students play in promoting awareness about prevention strategies among young people?
