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.

1. HIV is a Virus; AIDS is a Syndrome

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.

2. Not Everyone with HIV Develops AIDS

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.

3. HIV is Transmissible; AIDS is Not

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.

4. Diagnosis Methods Differ

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.

5. Treatment Goals Are Different

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.

Role of Community Engagement in Combatting HIV/AIDS

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 Independence Day and Janmashtami to Ganesh Chaturthi, Onam, Eid, Navratri, Dussehra, Diwali, Christmas and New Year, the period from August to January means celebrations across the country. However, some can also suffer from stress, loneliness and worsening of pre-existing mental health symptoms.

In India, festivals can provide connection, cultural continuity and family bonding. However, celebration is not positive for everyone. For some, the period can lead to issues such as social pressure, loneliness, grief, financial concerns and even interpersonal conflict. Festive periods can be challenging for the general population, while people with pre-existing mental health conditions may be vulnerable to worsening symptoms, increased sensitivities or relapse.

Festivals carry an expectation that everyone should be happy. People are expected to participate, dress up, attend gatherings and appear enthusiastic. Though some may experience anxiety, burnout, depression or emotional exhaustion, maintaining this expected level of participation can become another source of stress. Emotional wellbeing does not automatically change because it is a festival. Recognising this can reduce guilt and self-criticism.

Family Gatherings And Emotional Sensitivities

Festivals frequently bring extended families together. While this can strengthen relationships, it can also reactivate longstanding interpersonal dynamics. Questions about marriage, children, career, finances, appearance or personal choices can become uncomfortable, particularly when they touch existing vulnerabilities.

For someone who has experienced criticism or comparison within the family, a seemingly casual festive comment may carry considerably more emotional weight because of the history attached to it. The festive setting can therefore bring individuals into closer contact with relationships or unresolved issues that they may otherwise have greater distance from.

Why Clinical Populations May Be More Vulnerable

For individuals already living with a mental health condition, the festive season can introduce several stressors simultaneously. Travel, disrupted sleep, irregular meals, increased social stimulation, financial pressure, family conflict and interruptions to established treatment routines can place additional demands on psychological functioning.

People with conditions such as depression, anxiety disorders, bipolar disorder, trauma-related conditions, obsessive-compulsive symptoms, eating disorders or other psychiatric difficulties may be more sensitive to these changes.

In individuals with a history of recurrent episodes, significant disruption may also contribute to relapse. Festivals themselves do not necessarily cause relapse. Rather, the accumulation of environmental, interpersonal and behavioural stressors can increase vulnerability in someone already at risk.

Changes from an individual's usual baseline such as significant alterations in sleep, appetite, mood, anxiety, irritability, impulsivity, social withdrawal or functioning can therefore be important early warning signs.

Grief Can Become More Visible

Many traditions are built around shared experiences: preparing food, decorating homes, travelling to family members, exchanging gifts or gathering for meals. When someone important is no longer present, familiar rituals can make their absence more noticeable.

This can occur during religious festivals as well as occasions such as Independence Day or New Year, when people naturally reflect on their lives and relationships. Participating in a celebration does not mean grief has disappeared, just as sadness during a celebration does not eliminate the capacity for joy.

The festive season can also place pressure on household finances. Clothing, gifts, travel, home decoration and social events can increase expenditure over several months. For those already experiencing financial uncertainty, this can create considerable stress.

People living alone, those estranged from family, individuals experiencing relationship difficulties, older adults and people who have recently relocated may become more conscious of social isolation during this period. New Year can be particularly challenging because social expectations around parties, relationships and celebration become highly visible.

Indians Living Abroad: Culture, Belonging and Homesickness

Celebrating Diwali, Eid, Navratri, Onam, Christmas or Gurpurab away from India can provide an important connection with cultural identity and family traditions. At the same time, it can highlight physical distance from parents, siblings and extended family.

A person may attend a community celebration abroad while still missing the food, sounds, neighbourhood atmosphere and family rituals associated with celebrations in India. Those unable to travel home may experience increased homesickness, particularly when several major occasions occur within a short period.

Festivals Can Be Difficult For General Population Too

Feeling tired, overwhelmed, irritated, lonely or emotionally sensitive during a demanding period does not automatically indicate a psychiatric disorder.

Even psychologically healthy individuals can experience festive stress because of travel, social obligations, financial commitments or difficult family interactions.

Making The Festive Season Psychologically Sustainable

• Set boundaries around intrusive questions: “I’d rather not discuss that today” or “We’re comfortable with where things are right now” can end conversations about marriage, children or finances without confrontation.
• Decline invitations without over-explaining.
• A smaller number of meaningful gatherings may be preferable to trying to attend every event.
• Decide spending limits for gifts, travel and celebrations in advance rather than responding to social pressure.

For those receiving mental health care, prescribed medication, therapy and established support systems should not be casually disrupted during the festive period.

Curated festive content represents selected moments, not the entirety of another person's life.

Professional support becomes particularly important when festive stress is accompanied by persistent hopelessness, severe anxiety, substantial social withdrawal, changes in sleep or appetite, increased substance use, impaired functioning or other marked behavioural changes.

The goal is not to remove complexity from celebration, but to make space for it. Allowing people to experience the festive season without the pressure to feel festive can itself be an important form of psychological care.

As Delhi wakes up to another spell of deteriorating air quality just days ahead of Diwali, ophthalmologists warn that dust, smoke, particulate matter, and toxic gases can affect children's eyes, triggering redness, itching, burning, excessive watering, and dryness.

On Tuesday, India's national capital's average Air Quality Index (AQI) climbed to 331 at 7 am, entering the ‘very poor’ category. At the same time, eight monitoring stations recorded readings above 400, falling in the ‘severe’ zone, according to the Central Pollution Control Board (CPCB).

As per data from the CPCB, 33 of the city's 58 monitoring stations recorded AQI levels in the ‘very poor’ category. Meanwhile, the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology have forecast that air quality is likely to remain in the ‘very poor’ category over the coming days.

“Children’s eyes are more sensitive to irritants in the environment, and exposure to pollutants, particulate matter and toxic gases can irritate the surface of the eye,” Dr Shibal Bhartiya, Clinical Director – Ophthalmology and Program Director – Community Outreach and Wellness at Marengo Asia International Institute of Neuro and Spine (MAIINS), told HealthandMe.

How Does Air Pollution Affect Children's Eyes?

The experts warned that exposure to pollutants and particulate matter can irritate the surface of children's eyes, causing redness, itching, burning, excessive tearing and dryness.

Dr Neepa Thacker Dave, Senior Consultant in Paediatric Ophthalmology at SRCC Children's Hospital, told HealthandMe that the eye’s surface is protected by a delicate tear film that provides lubrication, maintains clear vision and helps defend against environmental irritants. Exposure to airborne pollutants can disturb this protective layer and contribute to ocular surface irritation and inflammation.

"Excessive watering does not necessarily mean that the eyes are adequately lubricated. Irritation can trigger reflex tearing even when the tear film is unstable. Consequently, children may experience watering alongside dryness or discomfort," she said.

Further, children with existing allergies or sensitive eyes may notice their symptoms worsening during periods of high pollution.

“Long-term exposure to poor air quality may also worsen pre-existing ocular surface conditions,” Dr Bhartiya said.

Reducing children's exposure to pollution is important, particularly on days when air quality is poor.

Dr Bhartiya advised parents to:

• Avoid outdoor activities when pollution levels are high.
• Keep windows closed during periods of severe pollution.
• Encourage children to avoid rubbing their eyes.
• Ensure children wash their faces after coming indoors.

Dr Dave also highlighted the importance of greater awareness, reduced exposure and timely medical care in protecting children from pollution-related eye irritation and discomfort.

When Should Children See an Eye Specialist?

Dr Dave said children may not always have the vocabulary to describe eye discomfort. Parents and teachers should watch for frequent eye rubbing, excessive blinking, squinting, watering or reluctance to participate in reading and outdoor activities.

Parents should not dismiss eye irritation in children, particularly when pollution levels are high.

Although mild irritation may improve when exposure is reduced, recurring or persistent symptoms warrant an eye examination. Eye pain, significant sensitivity to light, blurred or reduced vision, marked redness or difficulty opening the eye require prompt medical attention.

Type 2 diabetes is an incurable but manageable metabolic disorder that affects millions worldwide. But a new clinical trial has shown promise in reversing type 2 diabetes in young adults through intensive diet and exercise. It suggests that more than half younger adults with this condition may be able to achieve remission within six months through a structured programme combining a low-calorie diet with supervised aerobic and strength training.

The study, published in The Lancet Regional Health – Americas, found that 54% of participants who followed the intensive lifestyle programme achieved diabetes remission after 24 weeks. In comparison, only 4% of those receiving usual medical care reached the same outcome.

The research, called the RESET for Remission trial, was led by researchers from McGill University in Canada and the University of Leicester in the UK. It focused on adults with early-onset type 2 diabetes, a form of the disease diagnosed before the age of 45.

How Did The Study Test Diet And Exercise For Diabetes Remission?

The trial enrolled 96 adults aged 18 to 45 who had both obesity and type 2 diabetes. Participants were recruited at research centres in Montreal and Edmonton in Canada, and Leicester in the UK. None of them were using insulin.

Of these, 50 were assigned to the intensive diet-and-exercise programme, while 46 received usual medical care. For the first 12 weeks, participants in the intervention group followed a very low-calorie diet providing 800 to 900 calories a day.

During the first two weeks, they consumed meal-replacement products. From weeks three to 12, they could include one structured meal containing lean protein and vegetables alongside the meal replacements.

The programme also included supervised aerobic and resistance training twice a week, along with one independent exercise session each week. For the next 12 weeks, participants followed a healthy diet designed to maintain their weight loss and continued exercising.

Blood sugar and blood pressure medications were stopped at the beginning of the intervention under medical supervision, according to the study protocol.

To qualify for remission, participants had to maintain an HbA1c level below 6.5% without taking medication for at least 12 weeks. HbA1c is a blood test that reflects average blood sugar levels over approximately three months.

At the end of 24 weeks, 27 of the 50 participants in the intensive lifestyle group had achieved remission, compared to two of the 46 participants receiving usual care.

After considering relevant factors, researchers found that participants following the intensive programme were 21 times more likely to achieve remission than those receiving standard care.

The intervention group also experienced greater weight loss. Participants with available weight data lost an average of 8.4 kg over 24 weeks, compared to 1.2 kg in the usual care group. After adjustment, the difference in weight loss between the groups was approximately 7.5 kg.

The benefits were not just limited to body weight and blood sugar. MRI scans showed that participants in the intervention group lost more than 9% of their liver fat and more than 24% of their visceral fat, which is the fat stored around internal organs.

Their physical fitness improved, grip strength increased, and blood pressure and resting heart rate declined. Participants also reported fewer symptoms of depressed mood, distress and better quality of life.

Importance Of Strength Training

One of the important aspects of the programme was its focus on preserving muscle during rapid weight loss. Losing weight through severe calorie restriction can reduce both body fat as well as mass, which includes muscle. Researchers wanted to determine whether adding resistance training could help participants lose fat while maintaining muscle.

Lead author Dr Kaberi Dasgupta, professor of medicine and director of the Division of General Internal Medicine at McGill University, told Fox News Digital, "Our study shows that it is possible to combine a low-calorie diet with supervised exercise in young adults with type 2 diabetes," she said.

"There has previously been some concern about combining the two as being too much of a burden for people. However, people in our study stayed in our study."

Explaining the role of exercise in the results, Dasgupta said, "In our study, we think the diet provoked the weight loss, and exercise helped make sure it was [not] from muscle."

She added, "We were happy and surprised that not only did people lose fat from their organs and liver, our MRI studies indicated their muscle did not decrease at all and their handgrip strength went up."

The researchers also focused on muscle preservation. "Our findings demonstrate the feasibility and efficacy of combining structured aerobic and resistance exercise with a low energy diet in early onset type 2 diabetes, supporting its potential to deliver substantial and holistic health and well-being benefits alongside diabetes remission."

However, the trial did not include a separate group following the low-calorie diet without exercise. Therefore, researchers could not establish how much of the muscle preservation and fitness improvement was specifically due to exercise.

Dasgupta acknowledged this limitation and said, "The main limitation is that we had to compare the diet plus exercise with usual care," she said. "We would have liked to compare diet alone against diet and exercise to perfectly prove the point that the improvements in muscle and fitness were from the exercise."
