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 view generally is that the occurrence of knee issues is usually associated with age, injury or overexertion. However, there is another reason people ignore: lack of movement. If a person leads an inactive lifestyle, spending long hours sitting at a desk, working from the couch, watching TV or doing nothing physical, the eventual consequences for the knees might arise.
Knees are created for motion, and motion is essential for keeping the flexibility of a joint. Their effective functioning depends on the health of the muscles surrounding your knee. The less active various leg muscles are, including quadriceps and other counterparts, the weaker they will be. The muscles help stabilize the knee and can relieve it from some of the burdens during daily activities performed by the knees.
Remaining seated for an extended time can also lead to stiffness. When you sit for a while, you may feel uncomfortable or stiff in your knees when you finally stand up. While the occasional instance of stiffness may go away with movement, constant stiffness can impact mobility and cause people to wish to move even less.
Another issue is gaining weight. Living a sedentary lifestyle causes individuals to become heavier, and excess weight puts more stress on the knees. In time, this added pressure will lead to increased wear of the joints and the development of knee pain and other problems in the musculoskeletal system.
The positive aspect with respect to your knees is that you don’t have to put in hours at the gym to keep them safe. Small, steady efforts can easily do the trick. You can choose to walk for five minutes after being seated for a long time, stretch regularly, take stairs if you are physically able and do some simple workouts for the legs and thighs to increase strength. Low-impact sports such as swimming, cycling and walking can help you maintain muscle power and flexible joints while avoiding the stress on your knees resulting from extensive workouts.
Persistent pain in the knee, however, cannot be treated as a usual symptom of ageing. Knee swelling or prolonged stiffness, difficulties climbing stairs, instability, or pain that has an impact on routine activities should be addressed by health professionals.
Movement is necessary for knees to be strong and flexible. Therefore, if you want your knees to be strong, you need to use them consistently and perform all activities without remaining still for long.

Blocked ears are one of the most common and irritating problems associated with air travel.
While the sensation usually resolves on its own shortly after landing, for 22-year-old Aida Burkins from California, it persisted and eventually led to a frightening diagnosis of rare head and neck cancer.
Burkins was travelling to Chicago in May 2025 when her ears became blocked. When she returned home, her ears still hadn’t popped.
She later developed unusual symptoms, including hearing loss and bleeding from her throat.
“I started bleeding into my throat, which would only come out of my nose if I was bent at the hip at about 90 degrees,” the 22-year-old told Newsweek. “My hearing got worse and worse. Then I started getting more tired and losing weight.”
When Burkins sought medical help, her condition was initially dismissed as “just altitude sickness.” After several months, her hearing had deteriorated significantly.
“Everything sounded so muffled, and I had a ringing that wouldn’t go away,” she said.
Burkins eventually saw an ear, nose, and throat (ENT) specialist, who discovered a mass and noted that her adenoids — soft tissue in the throat, just behind the nose — were inflamed.
“The doctor told me he had never seen anything quite like what I had going on. He couldn’t be sure it was cancer, but he said it was very suspicious,” she told the outlet.
In February 2026, after undergoing CT scans and two biopsies, Burkins learned that she had a widespread tumour affecting the cervical lymph nodes near the base of her skull.
She was diagnosed with nasopharyngeal carcinoma, a rare type of head and neck cancer that starts in the upper part of the throat behind the nose and near the base of the skull, according to the American Cancer Society.
“Hearing I have cancer, all I thought about was not being able to see my babies grow up or do the things they want to do in life. It was horrifying,” Burkins, who is a mother to a 1-year-old and 3-year-old.
Burkins has since undergone months of chemotherapy and radiation. She is now finishing her treatment and hopes to be cancer-free soon as her body is responding well to the treatments.
According to the Mayo Clinic, nasopharyngeal carcinoma is a cancer that starts as a growth of cells in the nasopharynx, the upper part of the throat located behind the nose.
The cancer is rare in the United States and occurs much more often in other parts of the world, particularly Southeast Asia.
Nasopharyngeal carcinoma can be difficult to detect early because the nasopharynx is not easy to examine and there may be no symptoms initially.
When symptoms do occur, they present non-classic signs which include:
Treatment for nasopharyngeal carcinoma usually involves radiation therapy, chemotherapy, or a combination of the two, depending on the cancer and the individual patient.

Perimenopause has become a regular conversation and its been high time that people are talking about it. You can see friends discussing it, social media coverage has increased and more importantly women are discussing this with their gynaecologists.
For decades, menopause was thought to be a single event - that is the day the periods stopped, but today we understand that the transition lasts for a few years. These changes can affect the quality of a woman’s life and hence I’m glad the conversation has gained more traction.

First lets understand what perimenopause is. It literally means “around menopause” Its a transition phase where the ovaries gradually change the production of the hormones, mainly oestrogen and progesterone. It usually begins in the early 40’s but some women may experience it earlier.
One of the commonest signs of this is a change in the pattern of your menstrual cycle. Periods can be become longer or shorter, heavier or lighter. Basically the menstrual cycle becomes a bit unpredictable.
But periods aren’t the only sign. A woman may start experiencing disturbed sleep cycles. She may wake up randomly at 3am or feel exhausted despite getting 7-8 hours of sleep. Hot flushes and night sweats may also occur. Mood changes, irritability, anxiety and difficulty in concentration can also affect her quality of life.
Some women complain of being forgetful or more commonly used term "experience brain fog”. They forget names, lose train of though or struggle to multitask. There can also be a change in libido, vaginal dryness, discomfort during intercourse, headaches, join pain and alterations in skin and hair.
Besides this there could possibly a change in the body composition. A woman may notice increasing abdominal fat or find difficulty in maintaining her weight even though her lifestyle hasn’t changed.

The good part of this increase in awareness is that women are paying more attention to their health early rather than waiting of menopause. This transition phase provides a golden opportunity to reassess exercise, nutrition, sleep and preventative healthcare.
Strength training becomes even more valuable as it helps maintain muscle and bone mass.
Adequate protein, calcium and Vitamin D intake along with a balanced diet helps long term metabolic and bone health.
During this time, its important for a woman to even assess her cardiovascular health. Blood pressure, cholesterol, blood sugar and weight don’t just become numbers on the chart anymore, they become important markers of future health during this time.
However every label shouldn’t be blamed on perimenopause. Thyroid disorders, anaemia, vitamin deficiencies, depression and few other medical conditions can produce similar symptoms.
Unusually heavy bleeding, bleeding between periods or after intercourse also warrants medical assessment rather than being dismissed as “just hormones”.
