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.

Obesity, diabetes, and kidney diseases are three serious health issues that are linked to one another. These health issues have created a dangerous health triangle that is harming millions of people across the world.
When any of these health issues appear in a person’s health profile, the chances of developing the other health issues are high. These health issues are interconnected and may have a serious impact on a person’s health.
Obesity is a serious health issue that increases the risk of developing diabetes. Obesity increases the risk of developing diabetes because the extra fat accumulated in the abdomen interferes with the production of the hormone called insulin.
The hormone insulin helps the body regulate the levels of glucose present in the blood. If the levels of glucose are not regulated in the blood, a person may develop diabetes. If diabetes is not controlled over time, it may harm the kidneys.
The kidneys have an important function in filtering out wastes and extra fluids from the blood. However, high blood glucose levels, which occur in diabetes, can affect the small blood vessels in the kidneys. This results in diabetic kidney disease, also referred to as diabetic nephropathy.
This disease gradually impairs the function of the kidneys. If not treated, it can lead to chronic kidney disease or even kidney failure.
Being obese can also affect kidney function. This is because being obese forces the kidneys to work harder, thus leading to impairment.
Being obese can also lead to high blood pressure, which can cause kidney disease. It has been observed that if high blood pressure and diabetes occur simultaneously, there is an increased chance of kidney damage.
The good news is that this health triangle can be prevented or managed through a healthy lifestyle. Eating a healthy meal, exercising regularly, and keeping a healthy body weight are some of the steps that can be taken.
Monitoring blood sugar levels as well as blood pressure is important, especially for those who are overweight or have a family history of diabetes.
By taking early steps to diagnose and treat medical conditions, as well as making healthy lifestyle changes, it is possible to break the cycle of obesity, diabetes, and kidney disease.

In India, around 95 percent of kidney transplants and a significant proportion of liver transplants depend on living donors—primarily family members. While live donation can be lifesaving, it transforms a medical crisis into a family ordeal.
Parents feel obligated to donate to their children, spouses face immense pressure, and siblings also navigate complex emotional stress. This decision is typically free from the weight of duty, guilt, and family expectations. I have seen young professionals delay their careers, mothers hide their own health concerns, and elderly parents risk their lives—all because we lack a robust deceased donor program.
Moreover, the real challenge lies with living donors. Donors face surgical complications, long recovery periods, and potential long-term health consequences. While we counsel families about these risks, the urgency of their loved one's condition often overshadows rational decision-making.
Despite the introduction of the Transplantation of Human Organs Act and necessary amendments in India, the decrease in organ rates continues to remain abysmal—approximately 0.8 donors per million population, compared to 20 in the UK, 36 in Spain, and 33 in the United States.
Several deeply rooted factors explain this gap:
Cultural and religious misconceptions continue to persist. Many Indians also believe that the donation of organs conflicts with the religious beliefs regarding the sanctity of the body or rebirth, even though many religious institutions have endorsed organ donation.
The concept of brain death remains poorly understood; families struggle to accept that their loved one is dead when the heart still beats, and the chest rises on ventilator support. Families fear that clinical teams may hasten death to procure organs or that the wealthy will receive preferential treatment.
These anxieties, while often unfounded and deep-rooted, reflect legitimate concerns about transparency and equity in our healthcare institutions. We lack trained transplant coordinators, efficient organ retrieval networks, and standardized protocols across states.
When a potential donor is identified in a district hospital, the administrative maze often ensures organs go unutilized. Finally, public awareness is minimal.
Most Indians have never discussed organ donation with their families. Death remains a taboo subject, making advance directives about organ donation exceptionally rare.
Over 150,000 patients await kidney transplants; fewer than 10,000 receive them annually. Similarly, roughly 50,000 patients are listed waiting for a liver transplant nationally. For hearts and lungs, deceased donation is the only option, yet these transplants remain rare. Patients die waiting—not because medical expertise is lacking, but because organs are unavailable.
Our dependence on living donation also perpetuates inequality. Those without family networks, or
whose families cannot afford the medical evaluation and recovery costs for donors, are effectively excluded from transplantation. Deceased donation would democratize access.
Spain has the world's highest deceased donation rate, achieving success through a "Spanish Model" of dedicated transplant coordinators in every hospital, robust training programs, and a presumed consent system where all citizens are potential donors unless they opt out. Importantly, families are still consulted, but the default position favours donation.
Their success stems not just from infrastructure but from normalizing conversations about donation through media campaigns and school education programs.
A hybrid approach suited to Indian realities—combining elements of presumed consent with robust family consultation, investing in coordinator training, and launching sustained public awareness campaigns—could transform our landscape.
This transformation should be led by the government through several concrete actions:
First, invest in infrastructure. Every medical college and tertiary care center must have trained transplant coordinators and clear protocols for identifying and managing potential donors. State governments must establish well-funded organ retrieval networks with 24/7 operational capacity.
Second, Public awareness campaigns should be launched. Use television, radio, social media, and community health workers to educate citizens about brain death, the donation process, and the lives saved. Do a partnership with religious leaders to dispel the myths. Make organ donation part of school curricula.
Third, ensuring transparency and equity alongside establishing clear and publicly accessible waitlist protocols. To prevent commercialization, strict oversight from the government is recommended. Transplant programs must build trust by indicating that the system works for everyone, not just the privileged.
We must reframe organ donation from an extraordinary act to a normal, expected part of medical care at the end of life. This requires: Open family conversations and discussing their wishes regarding organ donation with the loved ones, also removing the burden of decision-making during the grief.
Celebrity and community leadership: When a pledge to donate is made by public figures, it enables a gradual shift in thought and practice.
Media responsibility: Gifts of life should be highlighted by news coverage, humanizing donors and recipients while respecting their privacy.
Medical community engagement: Doctors should initiate sensitive conversations regarding donation with families of brain-dead patients, considering it as part of compassionate end-of-life care rather than an awkward position.
With world-class transplant surgeons, excellent medical infrastructure in urban centers, and a population of over 1.4 billion. We should not have patients dying for lack of organs, and programs being heavily reliant on living organ donations.
What we lack is collective will, bold government action, and public education. As a society, we take pride in seva (service) and daan (giving), and organ donation should align perfectly with our values. Let us make it so.

In the world of oncology, we usually speak of battling or fighting cancer. We pool in our whole life’s earnings to find a cure or solution for the advanced stages of this disease. What if cancer were not a threat?
Here is one of the most common and deadly cancers, which is also one of the most preventable ones. We are talking about Colorectal cancer, which is often described by medical professionals as a preventable tragedy. This is because, unlike many other forms of the disease, we have a clear window of opportunity to stop it before it even begins.
As we observe Colorectal Cancer Awareness Month in March, it is time to strip away the fear surrounding the tests and understand why nobody should ever have to die from a condition that gives many chances to catch it well in time.
To understand why colorectal cancer is preventable, we have to look at how it develops. As with most cancers, this too doesn’t appear overnight. Almost always, these cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.
These polyps are like seeds; they are mostly benign. But there is one type of polyp that can gradually turn into cancer over a period of time. This is where the advantage lies. There is a long interval of time before polyps develop into cancer.
During this time, they can be removed if they are identified. If a doctor removes a precancerous polyp during a routine screening, they would not only have nipped the cancer in the bud, but would have also prevented it from occurring.
The statistics are encouraging when detected early, with figures showing that over 90 per cent of cases of colorectal cancer are fully curable. However, people do not seek medical attention until they experience some symptoms, at which point the seed-like polyps have already grown into a deep-rooted cancer.
In Western countries, the death rate from colorectal cancer has been declining at a visible rate due to the presence of strong and well-supported screening programs from their governments.
Although some countries have not yet introduced a formal national program, the consensus among medical experts is that if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened.
There are two primary ways we do this:
1. The FIT (Fecal Immunochemical Test) – This is a simple, non-invasive stool test that has become a staple in most general health check-up packages. It works by detecting tiny amounts of human hemoglobin (blood) that aren’t visible to the naked eye.
The advantage of getting a Fecal Immunochemical Test done is that it is very easy, and it can be done at home, and requires no special preparations. It acts as an early warning system. If a FIT result comes back high, it signals that something is happening in the bowel that requires a closer look via colonoscopy. It is recommended that everyone over 45 undergoes this test annually. While not as definitive as a colonoscopy, it is a vital first line of defence.
2. The Colonoscopy – This is the gold standard. Despite all the fear and misinformation that can be spread on the Internet, a colonoscopy is a routine and safe procedure. It allows a doctor to visually inspect the inside of the colon. It is a procedure that has dual benefits – to see what is wrong, and to make things right. Should the doctor find a polyp, it can be safely removed at the time of the procedure.
Many people avoid this procedure because of embarrassment and fear of discomfort. However, with the sedation, most people find it to be completely painless.
While screening is for people with no symptoms, you must be alert to signs that require an immediate expert opinion, regardless of your age. Also, never ignore these symptoms or assume that they are due to bad food choices:
The aim of Colorectal Cancer Awareness Month is not just to create awareness about the disease; it is also about providing support as we pay tribute to cancer warriors who have completed the painful journey from surgery and chemotherapy to rehabilitation. Shared stories can help remove the fear in others’ minds.
There is no such thing as too much information in the doctor’s office. Our bowels are part of our body, and we must overcome the shame or embarrassment associated with talking about them. A simple dialogue about bathroom habits or asking for a FIT test can save a life.
By promoting early detection leading to the removal of precancerous polyps, we can build a world where no one ever has to die from colorectal cancer. If you are aged 45 years or older, make this the month you arrange for a screening. If you have symptoms, do not wait; the right time is now.
In the case of colorectal cancer, prevention is not just the best medicine, it IS the cure.
