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.

The National Medical Commission (NMC) has issued an advisory mandating strict adherence to safe injection practices. The directive aims to curb preventable outbreaks of HIV, Hepatitis B (HBV), and Hepatitis C (HCV) caused by the unsafe reuse of syringes, needles, and other single-use medical devices.
Despite decades of evidence and repeated warnings from the World Health Organization (WHO), unsafe injection practices continue in India, often under the guise of cost-saving. This has led to avoidable infections, lifelong treatment costs, and a loss of public trust in healthcare systems.
The advisory mandates:
“India has the manufacturing capacity to supply safety-engineered syringes at scale. The barrier is not technology, it is willpower. Procurement administrators must prioritize patient safety over short-term cost-cutting,” said Rajiv Nath, Forum Coordinator of the Association of Indian Medical Device Industry.
“Single-use devices like syringes, dialyzers, and AV (Arteriovenous) fistula needles must not be reused. Unsafe injection practices are entirely preventable, and continuing them is indefensible,” he added.
The expert urged policymakers to act now because it is affecting

The AiMeD stated that the NMC's advisory must be treated as a binding mandate, not a suggestion. Procurement administrators, hospital authorities, and policymakers should:
"Unsafe injection practices are not a matter of affordability but of accountability. India has the capacity, technology, and cost-effectiveness evidence through Health Technology Assessment (HTA). What is needed now is decisive action to protect patients and healthcare workers alike," the AiMeD said.

Survival rates among patients with high-grade gliomas — one of the most aggressive forms of brain cancer — have improved by up to 50 per cent in India, according to leading oncologists ahead of World Brain Tumour Day 2026.
Doctors say a growing number of patients are now living significantly longer after diagnosis, with some surviving for more than a decade.
Dr. Tejinder Kataria, Chairperson of Radiation Oncology at Medanta, said median survival for many high-grade glioma patients has increased from around 9–12 months to 14–18 months.
She noted that some centers are "reporting nearly 40 per cent two-year survival rates among patients with Grade III and Grade IV gliomas. In addition, about 5 per cent of patients in certain high-grade glioma groups are now surviving for more than 10 years".
Experts attribute these improvements to advances in molecular diagnostics, comprehensive genomic profiling, neuronavigation-assisted surgery, precision radiation therapy, and targeted treatments.
“Radiation oncology has evolved from open beams in the cobalt era to highly precise beam configurations using modern technologies. We are now able to deliver tumoricidal doses more accurately while also preserving quality of life,” Dr. Kataria said.

Dr. R. Ranga Rao, Chairman of Medical Oncology at Paras Health, said brain tumor treatment is no longer limited to surgery and radiation.
A deeper understanding of tumor biology is enabling doctors to tailor treatment according to the molecular profile of each patient’s cancer.
“Although high-grade gliomas remain challenging to treat, the combination of precision diagnostics, modern therapies, and multidisciplinary specialist care is helping more patients live longer and maintain a better quality of life than was possible even a few years ago,” Dr. Rao said.
He also highlighted the growing role of whole genomic sequencing, which helps clinicians understand a tumor’s genetic makeup and select more personalized treatment strategies that may improve survival.
Dr. Shyam Agarwal, Senior Consultant in Medical Oncology at Sir Ganga Ram Hospital, said many patients fear the worst when diagnosed with a brain tumor.
“People often feel that nothing can be done once they hear the word tumor in the brain. But brain tumors are of many different types — benign and malignant — and even malignant tumors vary widely in behavior,” he said.
According to Dr. Agarwal, modern treatment options, including surgery, radiation, targeted therapies, and newer drugs, can control many brain cancers for extended periods and may even offer a cure in selected cases.
He also stressed the importance of molecular testing and comprehensive genomic profiling to identify patients who may benefit from precision medicines.
Despite advances in treatment, experts say delayed diagnosis remains a significant problem in India.
“The biggest blind spot in our country is that many patients reach specialists at a late stage. Symptoms may masquerade as routine headaches, hearing deficits, or visual disturbances. We need greater awareness,” Dr. Kataria said.
Dr. Agarwal added that delayed diagnosis is due to symptoms such as persistent headaches, hearing problems, or vision disturbances which are often mistaken for stress, migraine, or other common conditions, leading to late referrals.
As per the Johns Hopkins Medicine, glioma is a common type of tumor originating in the brain. About 33 per cent of all brain tumors are gliomas, which originate n the glial cells that surround and support neurons in the brains, including astrocytes, oligodendrocytes and ependymal cells.
Gliomas are called intra-axial brain tumors because they grow within the substance of the brain and often mix with normal brain tissue. Symptoms include

Canada has had a shortage of doctors, nurses, and other medical staff for many years, whereas just south of it, the United States does not have this kind of problem. It is not that no one wants to go and work in the Maple Leaf Country, but its strict regulations put a barrier between foreign professionals.
This complex issue has been addressed by the new report by the Institute for Canadian Citizenship (ICC), authored by Kareem El-Assal. This report, named Ready to Contribute, finds that the Canadian foreign qualification recognition (FQR) challenges are leaving nearly 640,000 immigrant degree-holders outside.
The report also said that these restrictions are causing harm to the medical industry in Canada, and it's not getting labour market success as their counterparts in the United States. The study also mentions that if the restrictions are lifted, then thousands of medical professionals will be able to contribute.
The study also states, “This translates into a disproportionate number of immigrant physicians working as security guards, engineers driving for ride-share apps, and nurses sorting packages in warehouses. This waste of talent hurts all Canadians, not just immigrants.”
The ICC report highlights that this strict policy has impacted Canada adversely. They reported that only 41 per cent of internationally trained physicians and 37 per cent of internationally trained nurses are working in their professions.
They said, “Lowering the immigrant overqualification rate to match the national rate has the potential to add 27,000 nurses and related professionals and nearly 16,000 medical doctors to Canada’s workforce. This illustrative example underscores the way in which immigrant underemployment impacts all Canadians, considering that 6.5 million Canadians do not have access to a family doctor.”

Canadian healthcare facilities' shortcomings have also become a problem for citizens, as the nation has approximately 4 million people with diabetes, or 9.7 percent of its population. Cancer and cardiovascular diseases are also issues, among others. There are also issues of having infectious and vector-borne diseases like Lyme disease and West Nile virus.

Diabetes is a condition characterized by high blood sugar (glucose) levels. It develops when the pancreas either doesn't produce enough insulin, doesn't produce any insulin at all, or when the body doesn't respond properly to insulin, a condition known as insulin resistance.
Diabetes Occurs Under The Following circumstances:
Lyme disease is caused by a bacterium called Borrelia burgdorferi. The most common cause of these diseases in humans is blacklegged ticks, though other variants can also be carriers. The Harvard Health says that most patients do not remember being bitten by a tick.
