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.

From childhood, many girls are taught to be agreeable, responsible and perfect in everything they do. They are praised for being obedient, hardworking and emotionally controlled. Over time, this expectation can shape behavior in ways that may quietly harm mental and physical health.
This pattern is often referred to as “Good Girl Syndrome”. While it is not a formal medical diagnosis, doctors say the effects of constantly trying to live up to expectations can be very real. The pressure to appear composed and capable all the time can lead to emotional suppression, chronic stress and eventually hormonal disturbances.
To understand how this pressure affects the body, NDTV Health spoke with Dr. Y. D. Meherprasad, Senior Consultant in Endocrinology and Preventive Healthcare at MGM Malar Hospital, Chennai, who says he has observed this pattern among many young women in his clinical practice.
Good Girl Syndrome describes a behavioral pattern where individuals, often women, feel compelled to meet expectations without showing weakness or stress. This can translate into people pleasing behaviour, fear of conflict and difficulty setting boundaries.
Dr. Meherprasad explains that constantly trying to maintain this image can create a persistent stress response in the body.
“Hormonal imbalances are being noticed in young Indian women associated with the Good Girl Syndrome, where women are always trying to meet expectations and are continuously successful, all without showing any signs of stress,” he told NDTV Health.
According to him, the problem arises when emotions are suppressed for long periods. “When women suppress emotions for long periods, the body remains in a state of constant stress response,” he said.
Emerging research in the field of psychoneuroendocrinology suggests that emotional stress can directly influence hormonal regulation in the body.
At the centre of this process is cortisol, the body’s main stress hormone. Normally, cortisol rises briefly during stressful situations and then returns to normal levels once the threat passes.
However, when stress becomes constant, cortisol levels can remain elevated for long periods.
Studies have shown that chronic high cortisol can disrupt reproductive hormones. One effect described in research is sometimes called “progesterone steal,” where the body prioritizes producing stress hormones instead of reproductive hormones.
Low progesterone levels can contribute to irregular menstrual cycles, acne and other hormonal symptoms that many young women experience.
Dr. Meherprasad says chronic stress may also contribute to metabolic changes. In some cases, it can mimic or worsen conditions such as Polycystic Ovary Syndrome (PCOS).
When cortisol levels remain high, the body releases more glucose into the bloodstream to provide energy for a perceived threat. If that energy is not used through physical activity, insulin levels rise to regulate blood sugar.
Over time, this can lead to insulin resistance, which is a key factor associated with PCOS. Women may experience abdominal weight gain, irregular ovulation and difficulty managing their weight.
The effects of prolonged stress do not appear overnight. They often show up gradually through subtle changes in the body.
Dr. Meherprasad says menstrual irregularities are one of the early warning signs. Some women may experience delayed cycles or even a temporary halt in ovulation.
Sleep disturbances are also common. Many women report difficulty falling asleep because their minds remain constantly active, leading to fatigue the next day.
Other symptoms may include mood swings, persistent anxiety, brain fog and difficulty losing weight despite maintaining a careful diet.
Dr. Meherprasad says addressing these hormonal issues requires both medical evaluation and lifestyle changes.
Regular hormone screenings can help detect issues related to thyroid function, insulin levels and reproductive hormones such as LH and FSH. Early treatment is important if conditions such as PCOS or thyroid dysfunction are present.
Equally important is addressing the emotional component of chronic stress.
“Hormonal imbalance is not only physical but also closely linked to emotional health,” said the doctor.
He recommends prioritizing adequate sleep, regular physical activity and practices such as yoga that help calm the body’s stress response. Creating space for emotional expression through journaling or therapy can also help reduce long term stress.
In a culture that often rewards perfection, doctors say it may be time to rethink the idea of the “perfect girl”. Sometimes, protecting one’s health begins with allowing space for imperfection.
Cancer deaths in the United Kingdom have dropped to their lowest recorded levels, according to new data from the charity Cancer Research UK. The figures show that cancer death rates have fallen by 11 per cent in the past decade, reflecting progress in early detection, screening, treatment and prevention.
Researchers estimate that around 247 people in every 100,000 in the UK now die from cancer each year. This is a significant decline from the peak recorded in 1989, when about 355 people per 100,000 died annually from the disease. Overall, that represents a 29 per cent reduction over the past few decades.
Experts say this steady improvement is the result of sustained scientific progress, improved healthcare systems and public health measures that target risk factors such as smoking.
The new data highlights falling death rates across several major cancers. Ovarian cancer deaths have dropped by 19 per cent over the past ten years, up to 2024. Lung cancer deaths have fallen by 22 per cent during the same period, reflecting the long-term impact of reduced smoking rates and better treatment options.
Deaths from stomach cancer have seen one of the most dramatic improvements, dropping by 34 per cent in the past decade. Bowel cancer deaths have decreased by six per cent, while breast cancer deaths have fallen by 14 per cent.
Other cancers have also seen notable declines. Cervical and prostate cancer deaths have both dropped by 11 per cent. Deaths from leukemia are down by nine per cent, while esophageal cancer deaths have fallen by 12 per cent.
Experts say improved diagnosis, new therapies and better awareness are playing a key role in these trends.
One of the biggest public health successes has been the decline in cervical cancer deaths. Since the 1970s, deaths from cervical cancer have fallen by around 75 per cent in the UK. Health experts attribute much of this progress to the national cervical screening programme run by the NHS.
Screening helps detect abnormal cells early, allowing treatment before cancer develops or spreads.
Another major contributor is the human papillomavirus vaccine, commonly known as the HPV vaccine. The vaccine protects against the virus responsible for most cervical cancer cases. It is routinely offered to schoolchildren in the UK, and since its introduction in 2008, at least 6.5 million young people have received it.
Public health experts believe the vaccine will continue to reduce cervical cancer rates in the coming decades.
Despite the overall progress, the data also shows worrying increases in deaths from certain cancers. Gallbladder cancer deaths have risen by 29 per cent, while deaths from eye cancer have increased by 26 per cent.
Liver cancer deaths are up by 14 per cent, and kidney cancer deaths have risen by five per cent. Meanwhile, death rates for thyroid cancer, pancreatic cancer and melanoma have remained largely unchanged.
Another important trend is that the total number of people dying from cancer continues to rise. This is largely due to population growth and an ageing population, as cancer risk increases with age.
Experts say the long-term decline in cancer deaths reflects decades of medical research and innovation. However, they stress that continued investment is necessary to sustain progress.
Cancer Research UK researcher Dr Sam Godfrey said the figures show the impact of scientific breakthroughs over many years. He has called on the government to support more clinical trials and ensure that NHS staff have enough time and resources to take part in life saving research.
Public health policies such as smoking bans, along with screening programmes and vaccines, are also credited with helping drive down cancer deaths across the country.

Are you in the habit of catching up on social media or news updates while sitting on the pot? A new study shows you may be "unintentionally" spending extra time and increasing your risk of developing painful hemorrhoids by 46 percent.
The study, published in the open-access journal PLOS One, explained that getting distracted by news or social media can increase pressure on sensitive anal tissues, which leads to hemorrhoids.
Hemorrhoids, also called piles, are swollen and inflamed veins around your anus or in your lower rectum.
"Using a smartphone while on the toilet was linked to a 46 percent increased chance of having hemorrhoids. We're still uncovering the many ways smartphones and our modern way of life impact our health,” Trisha Pasricha, from the Beth Israel Deaconess Medical Center in the US.
“It's possible that how and where we use them -- such as while in the bathroom -- can have unintended consequences," she added.
For the study, the researchers examined data from colonoscopies of 125 adults in America, and conducted an online survey to understand their lifestyle habits and behavior while using the toilet.
Two-thirds of the participants reported using their smartphones while on
the toilet. Compared with those who did not, endoscopists found that they had a 46 percent higher risk of hemorrhoids.
More than a third of bathroom smartphone users reported spending more than five minutes there during a single visit -- reading news (54.3 percent), or browsing social media (44.4 percent).
In comparison, just 7.1 percent of non-users reported staying that long.
"Smartphone use may unintentionally extend the time people spend sitting on the toilet. Sitting for longer periods could increase pressure on tissues in the anal region, which may contribute to the development of hemorrhoids,” the researchers said.
Pasricha suggested individuals leave smartphones outside the bathroom to understand the actual time it takes for a bowel movement.
"If it's taking longer, ask yourself why. Was it because having a bowel movement was really so difficult, or was it because my focus was elsewhere?" she said, calling for more studies.
Studies estimate that hemorrhoidal disease affects 40% of people all over the world, and it is one of the most common diseases in the anorectal region.
The two types of hemorrhoids are:
