World Aids Day
The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change. Despite the significant strides made in treatment and prevention, the confusion surrounding the relationship between HIV and AIDS still persists.
Young people have become influential advocates in the fight against HIV/AIDS. Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities. These young activists utilize digital platforms and peer-to-peer education to dispel myths, promote safe practices, and foster supportive environments for those affected by HIV/AIDS.
Dr Gowri Kulkarni, an expert in Internal Medicine, explains that while the terms HIV and AIDS are often used interchangeably, they are distinctly different. "HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a condition that occurs when HIV severely damages the immune system," she clarifies. To understand the implications of these differences, it's important to explore the fundamental distinctions between the two.
HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.
AIDS, on the other hand, is a syndrome, not a virus. Dr Kulkarni further elaborates that AIDS is a collection of symptoms and illnesses that emerge when the immune system is severely compromised due to prolonged HIV infection. It represents the most advanced stage of HIV, and is characterized by very low CD4 counts or the onset of opportunistic infections like tuberculosis, pneumonia, or certain cancers.
A key distinction to remember is that not everyone with HIV will progress to AIDS. Thanks to advancements in medicine, particularly antiretroviral therapy (ART), individuals living with HIV can manage the virus and maintain a healthy immune system for many years, or even decades, without ever developing AIDS. ART works by suppressing the virus to undetectable levels, effectively preventing the damage HIV would otherwise cause to the immune system.
Without treatment, however, HIV progresses through three stages:
- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.
- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.
- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.
Another key distinction between HIV and AIDS is the way in which they are transmitted. HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding.
AIDS, however, is not transmissible. It is not a disease that can be passed from one person to another. Rather, AIDS is the result of untreated, advanced HIV infection and is a direct consequence of the virus’s damage to the immune system.
HIV and AIDS are diagnosed through different methods. HIV is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.
AIDS, on the other hand, is diagnosed using more specific criteria. Dr Kulkarni notes that the diagnosis of AIDS is made when the individual’s CD4 cell count falls below 200 cells/mm³, or when opportunistic infections or certain cancers (such as Kaposi's sarcoma or lymphoma) are detected. Diagnosing AIDS involves a more thorough assessment of the individual’s immune function and overall health, as opposed to just the detection of HIV.
The treatment goals for HIV and AIDS differ significantly, although both involve antiretroviral therapy (ART). For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to ART.
For individuals diagnosed with AIDS, the treatment plan becomes more complex. While ART remains an essential part of managing the virus, treatment for AIDS also focuses on addressing the opportunistic infections and secondary health complications associated with severe immune suppression. The goal of treatment for AIDS is not only to manage the HIV virus but also to improve the quality of life and extend survival by treating these secondary health issues.
While the medical community has made great strides in managing HIV, the battle to curb its transmission is also a social and cultural issue. Dr Daman Ahuja, a public health expert, highlights that HIV/AIDS awareness and education are vital to reducing transmission rates and supporting those affected by the virus. "Young people, especially, have become key advocates in the fight against HIV/AIDS," says Dr Ahuja. "Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities."
Additionally, grassroots activism plays a significant role in raising awareness and addressing stigma. As the World Health Organization reports, community-based interventions have been proven to increase HIV testing rates and improve treatment adherence, which are crucial in the fight against the pandemic.
The ultimate goal of organizations like UNAIDS is to eliminate the HIV/AIDS pandemic by 2030. Achieving this requires global collaboration, from medical treatment advancements to public health strategies, education, and advocacy. Dr Kulkarni’s insight underscores the importance of early detection, treatment adherence, and community support in the fight against HIV/AIDS.

Amid increasing contamination and adulteration of food products, India’s food regulator has introduced new safety standards across a wide range of foods such as besan (gram flour), edible and cold-pressed seed oils, as well as prawns.
The draft regulations by the Food Safety and Standards Authority of India (FSSAI) cover heavy metals, toxins, antibiotic residues, and quality standards for both commonly used foods and emerging edible products, the Times of India reported.
The new regulations are expected to come into force on December 1.
Under the new rules, the FSSAI has:
In a separate draft notification, the FSSAI proposed quality and safety standards for lesser-used edible oils made from chilli, tomato, muskmelon, and okra seeds as demand rises for cold-pressed oils, seed-based snacks, and plant-based nutrition products.
The proposed norms require these oils to remain free from adulteration, harmful impurities, rancidity, and mineral oil contamination, while also prescribing limits for moisture, acidity, and metal content.

The draft rules also cover edible seeds such as watermelon, cucumber, pumpkin, sunflower, sesame, and flaxseed sold in raw, roasted, or salted forms, requiring them to be clean and free from insects, fungus, and visible contamination before sale.
FSSAI has invited public comments on the draft regulations for 60 days before finalization.
In Ghaziabad, the state food regulator seized 10 quintals of suspected paneer stored in unhygienic conditions. With contamination risks high, the joint team swiftly sampled the batch and destroyed the entire 1,000 kg consignment.
In Muzaffarnagar, food safety officials inspected an ice cream outlet. The drive focused on ice creams and ice candies to ensure they met regulatory standards. A total of three legal samples were collected.

The FSSAI noted that hidden adulterants in everyday food can create serious concerns for consumers.
Food adulteration happens when there is an intentional addition of foreign or inferior substances to original food products.
A 2024 study published in SAGE Open Medicine noted various health impacts of adulterated food, including:
The study also noted that adulteration could lead to allergic reactions. Pregnant women, children, and the elderly are more prone to developing illnesses if adulterated food is consumed.

Do you smoke herbal cigarettes believing they are “natural”, “chemical-free”, and “tobacco-free”? You may be mistaken. New research, ahead of World No Tobacco Day 2026, has raised concerns over the growing popularity of herbal cigarettes, suggesting that herbal cigarettes are not safer than conventional cigarettes and may be equally harmful to health.
The new joint study by the Indian Institute of Technology Gandhinagar (IITGN) and the University of Illinois Urbana-Champaign (UIUC), US, has found that herbal cigarettes can produce emissions comparable to — and in some cases more harmful than — those generated by tobacco cigarettes.
The study, published in the Journal of Hazardous Materials, highlight significant health concerns surrounding herbal smoking products, many of which currently fall outside India’s primary tobacco control laws.
The study compared emissions from two of India’s best-selling tobacco cigarette brands and four popular herbal cigarette varieties containing ingredients such as basil, clove, cinnamon, mint, green tea, water lily, and chamomile.
Two of the herbal products also used tendu (ebony) leaves as wrappers — the same material commonly used in bidis, India’s most consumed smoking product.

Researchers analyzed the physical, chemical, and oxidative properties of mainstream smoke generated from the products. According to the study, herbal cigarette smoke released extremely fine particles and toxic compounds at levels similar to or exceeding those found in tobacco smoke.
“Our findings challenge the widely held belief that tobacco-free means risk-free. Emissions from herbal cigarettes are comparable to or exceed those from tobacco cigarettes on nearly every metric we measured. Leaf-wrapped herbal variants turned out to be the most hazardous of all the samples tested,” said Prof. Sameer Patel, Assistant Professor at IITGN’s Department of Civil Engineering and Chemical Engineering.
Further, the researchers combusted each cigarette inside a sealed automated two-chamber system designed to mimic human inhalation patterns, to decode particle size, chemical composition, and oxidative potential.
Shockingly, the team found that particles smaller than 500 nanometers — associated with cardiovascular and respiratory diseases — were emitted at nearly 20 per cent higher concentrations in herbal cigarette smoke compared to tobacco smoke.
The study also measured the “oxidative potential” (OP) of smoke particles — a marker of their ability to generate reactive oxygen species that contribute to inflammation, lung damage, and vascular disease.
According to the researchers, particulate matter from herbal cigarettes showed significantly higher oxidative potential than tobacco cigarettes. Tendu-leaf-wrapped variants recorded OP levels nearly 49 per cent higher than paper-wrapped products.
Notably, one basil-filled herbal cigarette marketed as “100% natural” and “chemical-free” showed the highest lead concentration among all products tested.
Prof. Vishal Verma, Associate Professor of Environmental Engineering at UIUC and co-author of the study, said the results are particularly significant because many consumers believe nicotine-free products are less harmful.
“That finding is important because many consumers associate nicotine-free products with reduced harm,” he said.

Researchers also pointed to regulatory loopholes surrounding herbal cigarettes. India’s Cigarettes and Other Tobacco Products Act (COTPA), 2003, regulates tobacco products through health warnings, advertising restrictions, and public smoking rules. However, many products marketed as tobacco-free do not fall under the same regulatory framework.
Lead author Dr. Alok Kumar Thakur said several herbal cigarette brands claim therapeutic benefits, including relief from cough, anxiety, and sleep problems, despite limited scientific evidence on their safety.
“However, there is limited scientific evidence evaluating the emissions and toxicological impacts of these products,” he said.
The findings also align with the World No Tobacco Day 2026 under the theme, “Unmasking the appeal: countering nicotine and tobacco addiction.”
The researchers stressed the urgent need for evidence-based regulation and stricter oversight of alternative smoking products to prevent misleading health claims and protect public health.

Digestive disorders are becoming a global health issue affecting millions of people of all ages all over the world. Conditions such as acid reflux, fatty liver disease, irritable bowel syndrome, inflammatory bowel disease, constipation, and colorectal cancer are becoming more prevalent on a steady basis, fueled by changing diets, sedentary lifestyles, stress, poor sleep, alcohol consumption, and increasing obesity rates.
But digestive symptoms are often ignored until they are severe. Bloating, ongoing acidity, irregular bowel habits, abdominal discomfort, unexplained weight loss, or chronic fatigue are often brushed aside as temporary problems. In many cases, these early signs are reflective of an underlying gastrointestinal disease that is amenable to timely intervention.
This is a particularly important problem because digestive health impacts far more than just the stomach or intestines. The gut is key to immunity, metabolism, nutrient absorption, hormone regulation, and even mental health.
Damage to the gut can therefore impact many systems in the body. Colorectal cancer is diagnosed more frequently in younger adults worldwide, and fatty liver disease is one of the fastest-growing metabolic disorders worldwide. The increase in ultra-processed foods, reduced intake of fiber, and sedentary lifestyles have also played a part in digestive dysfunction in developed and developing countries alike.
This shift is also changing the way health care systems address preventive care and patient engagement.
Early screening, continuous monitoring, digital health tools, and data-driven care models are gaining importance in identifying digestive disorders before complications escalate.
Growing Role Of Preventive Care And Technology
As healthcare moves towards being more personalized and preventive, technology-enabled patient engagement and longitudinal health tracking are taking on a greater role in improving outcomes and supporting long-term disease management. Late diagnosis is still a big problem.
Many GI diseases develop silently for years before complications arise. For example, fatty liver disease can progress to liver inflammation or fibrosis without symptoms.
Similarly, inflammatory bowel diseases and gastrointestinal cancers are often more challenging to treat when diagnosed late. Diet also continues to be central to digestive health. Eating a diet high in fiber, staying well hydrated, getting enough physical activity, and eating less ultra-processed foods will promote healthy gut function and reduce risk over the long term.
World Digestive Health Day
World Digestive Health Day is a reminder that digestive symptoms shouldn’t be ignored or normalized. Early attention, timely diagnosis, and preventive care can greatly reduce the long-term burden of digestive disease worldwide.
