The recent revelation by the Centers for Disease Control and Prevention (CDC) of HIV transmission via cosmetic needles has underscored the multifaceted nature of HIV transmission. According to Dr Balakrishna G K, HOD and Senior Consultant Internal Medicine at Gleneagles Hospital Kengeri, Bengaluru, when HIV is transmitted, the immune system becomes significantly weakened. This increases susceptibility to illnesses that typically do not affect those with a healthy immune system and can prove to be lethal. Hence it is imperative to understand HIV transmission beyond conventional means. In exploring the diverse avenues through which HIV can be contracted, we illuminate the complexities and nuances of this pervasive virus.
Ways HIV Can Be Transmitted
Transmission Through Sexual Intercourse
The predominant mode of HIV transmission remains through unprotected sexual intercourse, encompassing both vaginal and anal sex. Engaging in sexual activity without barrier methods or antiretroviral therapy significantly heightens the risk of HIV transmission. The receptive partner in anal sex faces heightened vulnerability due to the thin lining of the rectum, facilitating the entry of the virus into the bloodstream. Similarly, vaginal intercourse presents a risk, with HIV gaining access through the delicate tissues of the vagina and cervix.

Perinatal Transmission
Mother-to-child transmission, though less common today due to advancements in prevention and treatment, remains a significant mode of HIV acquisition. During pregnancy, childbirth, or breastfeeding, the virus can be passed from an HIV-positive mother to her infant. However, diligent adherence to antiretroviral therapy during pregnancy and breastfeeding substantially mitigates this risk, exemplifying the efficacy of preventive measures.
Injection Drug Use
Sharing needles, syringes, or other drug paraphernalia poses a substantial risk for HIV transmission. Intravenous drug use, characterised by the sharing of contaminated equipment, perpetuates the spread of the virus through blood-to-blood contact. Implementing harm reduction strategies, such as needle exchange programs and access to sterile injection equipment, is paramount in curbing HIV transmission among individuals who inject drugs.

Uncommon Modes of Transmission
While certain activities pose minimal risk of HIV transmission, rare occurrences highlight alternative pathways for infection. Oral sex, albeit low risk, can facilitate transmission under specific conditions, such as the presence of oral ulcers or bleeding gums. Workplace incidents involving needle injuries underscore the importance of stringent safety protocols in healthcare settings. Similarly, isolated cases of HIV transmission through food contamination serve as a reminder of potential risks in unconventional scenarios.
Dispelling Myths and Misconceptions
Debunking myths surrounding HIV transmission is crucial in fostering accurate understanding and combatting stigma. HIV cannot be transmitted through casual contact, such as kissing, touching, or sharing food. Contrary to misconceptions, HIV does not spread through saliva, intact skin, or closed-mouth kissing. These clarifications dispel unfounded fears and promote informed interactions with individuals living with HIV.
Cosmetic Procedures and Bloodborne Pathogens
The emergence of HIV transmission via cosmetic needles underscores the intersection of healthcare practices and infection control standards. While cosmetic procedures, including tattoos and body piercings, generally pose minimal risk, lapses in infection control protocols can lead to dire consequences. Ensuring adherence to stringent sterilisation practices and utilising new or sterilised equipment is paramount in mitigating the risk of bloodborne pathogen transmission.
Bottomline
The identification of HIV transmission through cosmetic needles serves as a poignant reminder of the diverse routes through which the virus can spread. By comprehensively examining modes of transmission, from sexual intercourse to unconventional scenarios, we equip ourselves with the knowledge necessary to combat HIV effectively. Vigilance, education, and adherence to preventive measures remain our most potent tools in the ongoing battle against HIV/AIDS.
