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.

Beyond being a medical challenge, multiple sclerosis (MS), which affects nearly three times as many women as men, raises emotional and physical concerns among women.

MS is a neurological condition that affects cognitive, emotional, motor, sensory, or visual functions. It is also a chronic autoimmune disease that is caused when a person’s immune system attacks their brain and spinal cord.

According to the UK-based MS International Federation, an estimated 2.8 million people live with MS worldwide, with prevalence increasing globally. However, women make up about 75 percent of MS patients globally.

However, women are disproportionately affected. The diagnosis gets more emotionally challenging for women as it often appears during early adulthood -- a key period for women building their careers, relationships, and families.

Estrogen, genetics and a lack of Vitamin D are major reasons for its increased prevalence in women.

Beyond the clinical symptoms, the anxiety, depression, mood changes, and stress, driven by uncertainty about disease progression, impact the daily life of women. Concerns about pregnancy, parenting, work, and long-term independence can further intensify the emotional burden.

“MS is significantly more prevalent in women, often striking during their most pivotal years. For many women, the diagnosis goes beyond a medical challenge; it becomes a profound emotional crossroads centered around family planning. They face daunting questions: Can I safely carry a pregnancy? Is breastfeeding possible? Will I have the physical stamina to care for a child? These are not merely clinical concerns; they are deeply personal anxieties about identity, motherhood, and the future,” Dr. Sudhir Kumar, Sr. Consultant Neurologist, Apollo Hospital, Jubilee Hills, Hyderabad, told HealthandMe.

“Multiple sclerosis is increasingly recognized as a disproportionate neurological burden among women. Globally, women are affected nearly two to three times more often than men, a pattern believed to arise from a complex interaction of immune system behavior, hormonal influences such as estrogen fluctuations, genetic susceptibility, and environmental triggers, including low Vitamin D levels and viral exposures,” added Dr. Manish Gupta, Director – Neurology, Max Super Specialty Hospital, Noida.

Symptoms of multiple sclerosis can be different from person to person. They can come and go or get worse over time. MS can affect any part of the central nervous system.

MS symptoms can worsen with heat or during other infections, such as urinary tract or respiratory infections.

Common symptoms can include:

• vision problems
• difficulty walking or keeping balance
• difficulty thinking clearly
• numbness or weakness, especially in the arms and legs
• muscle stiffness
• depression
• problems with sexual function or urination
• feeling very tired.

“No two patients experience MS in the same way. Symptoms depend on the location of demyelinating lesions in the brain or spinal cord, affecting vision, mobility, cognition, balance, or sensation. This biological variability makes early diagnosis and timely, high-efficacy intervention critical. The goal today is no longer just to manage relapses. It is to limit ongoing subclinical inflammation, prevent silent progression, and delay long-term disability,” Dr. Kumar said.

Why Treating Multiple Sclerosis Is Difficult

MS is an inflammatory condition that results from an autoimmune attack on myelin -- the fatty insulation that surrounds the nerves in the brain and spinal cord.

This disrupts the electrical impulses that are sent through the nerves to the rest of the body and results in scars (plaques or sclerosis).

“Multiple Sclerosis is one of the most complex neurological disorders we encounter in clinical practice, not because it is untreatable, but because it is unpredictable. MS is an immune-mediated disease characterized by inflammation and demyelination — damage to the protective myelin sheath that insulates nerve fibers in the brain and spinal cord. When this insulation is stripped away, nerve signals slow down or become distorted, producing a wide spectrum of symptoms, varying from fatigue, blurred vision, and dizziness to limb weakness, imbalance, or sensory disturbances,” Dr. Subhash Kaul, Consultant Neurologist at KIMS Hospital, Hyderabad, told HealthandMe.

Many of these are invisible, fluctuating, and easily dismissed, both by patients and sometimes even by primary care providers. It is not uncommon for individuals in the early stages of MS to be misdiagnosed.

“This delay in recognising the disease is deeply concerning, because MS strikes people in the prime of their lives — when they are building careers, raising families, and contributing economically. If left untreated, the disease does not remain static; inflammation accumulates silently, relapses leave residual deficits, and disability compounds over time. This is precisely why early and appropriate treatment matters,” said Dr. Kaul.

Yet, experts stated that early diagnosis remains crucial. Regular neurological evaluation for persistent numbness, vision disturbance, or unexplained fatigue allows timely therapy. Disease-modifying treatments, adequate sunlight exposure, physical activity, and stress management help slow progression and preserve long-term neurological function.

“Multiple Sclerosis is not a series of unfortunate episodes; it is a silent, relentless fire. From the moment of onset, MS acts as a chronic, immune-mediated assault on the central nervous system, often causing irreversible damage long before the first visible symptom appears. As one of the leading causes of non-traumatic disability in young adults, we must confront a sobering reality: even when a patient appears clinically stable, “smoldering” inflammation frequently continues beneath the surface, gradually eroding brain volume and neural pathways,” Dr. Kumar said.

“By intervening decisively at the outset, we can suppress smoldering inflammation, preserve long-term neurological function, and give women the confidence to pursue the lives and families they envision,” he added.

Chief Minister Siddaramaiah’s announcement during his presentation of the Karnataka State Budget 2026-27, proposing a ban on social media for children under 16 years of age, has sparked intense interest among parents and professionals alike. As the first state in India to attempt such a sweeping measure, the government has invited us to reflect upon this proposal.

We are in an age where technological advancements have blurred the lines between online and offline worlds, blending them seamlessly. While this is the norm in the world of adults, it has silently reshaped childhood with increased screentime.

Concerns about digital dependency, anxiety disorders in children, and reduced focus in academic and non-academic tasks have already made it to research papers and therapy rooms.

But Karnataka has now shifted the focus from debate to discussion and action. While a ban may reduce certain risks of social media exposure, children’s psychological needs like social connection, belonging, peer group and individual identity, besides guidance, must be nurtured if such protections are to be meaningful.

The Pediatric Perspective: A Medical Minefield

From a psychological perspective, the idea of an age-based social media ban is both promising and complex. On the brighter side, reducing screen usage can help address problems of poor sleep schedules, heightened anxiety, and trouble concentrating in studies or tasks. These problems have become increasingly common among not only adolescents, but very young children too.

However, age alone cannot be used as the single measure of readiness to implement this proposal. Two children of the same age may differ vastly in maturity levels, coping skills, and the ability to use technology responsibly.

The deeper issue is not simply “how much time” children spend online, but “what they do there”. Creative exploration, learning, and connection can be enriching, while endless scrolling reinforces dependency and stress.

A ban can reduce such harmful patterns, but in order to have real impact, such a move should be paired with support for children’s psychological needs to help them combat loneliness, handle peer pressure, and guiding their search for identity. Addressing these issues along with the ban can make the protection well intended, more meaningful and long-lasting.

The Silent Crisis: Nocturnal Anxiety And Doom-scrolling

Late-night scrolling (doom scrolling) is more than just a disruption of sleep. It is a psychological trigger for worry and overthinking. In the quiet of the night, children are left alone with a flood of unfiltered information, which can heighten anxiety, and unwanted exposure to inappropriate content.

An effective way to combat the dangers of unsupervised social media access could be “digital sundowning” i.e. setting clear screen time guidelines for children. Families can create screen-free zones, especially in bedrooms, bathrooms, and at dining tables, or create “phone parking zones” – a specific place in the house to keep all phones so no one is carrying them around all the time. This can encourage children towards healthier routines.

Unlike government-imposed bans, household practices can set healthy and firm boundaries, reinforce self-regulation and reduce the anxiety that comes from constant connectivity and information overload.

Symptoms In The Clinic: Beyond The Screen

In therapy rooms and schools, counsellors are addressing more and more concerns about children and adolescents spending excessive time with their screens. Some of the common ones are highlighted here:

• Social Isolation in Hyper Connectivity: Children may appear socially active online but withdraw from face-to-face interactions, leaving them paradoxically isolated.

• Body Image Concerns: Exposure to curated images on social media can fuel anxiety about appearance among growing children, who are already socially awkward during adolescence. This goes beyond normal teenage insecurity and can spiral into unhealthy self-image or self-criticism.

• Academic Fatigue: Digital content trains the brain to expect constant novelty and quick changes within a short time span of seconds or minutes, which makes textbooks and traditional classroom driven problem-solving feel slow and tiring. This leads to academic fatigue, where children struggle to sustain focus for deeper learning.

• Fear of Missing Out (FOMO): Constant checking of devices reflects a deep-seated need for validation and belonging. FOMO keeps children’s nervous systems on a constant loop of high alert, thus undermining emotional stability.

What Comes Next: The Prioritization Framework

For this ban to have a lasting impact, it needs to draw on psychological principles. Restrictions work best when paired with meaningful alternatives, as children are known to engage positively when they feel supported rather than restricted or scolded. A framework needs to be set up where learning and guidance is prioritized and alternatives offered are strengthened. Some pointers:

Digital Literacy in Schools: Children should be taught not only to limit screen time but also to understand how online platforms work. Lessons on algorithms, advertising, and curated content help them understand and evaluate what they see, so they become more resilient to digital influence.

Parental Guidance Programs: As with other trained behaviors, parents play a central role in shaping healthy digital habits too. Guidance programs can provide resources and strategies for families to showcase balanced device use. When adults demonstrate mindful online usage and behavior, children are likely to follow.

Physical and Social Alternatives: If digital spaces are restricted, offline opportunities must be strengthened. Sports, arts, and community activities help children gain a sense of belonging and enjoyment beyond screens, thus building confidence and social skills in real life.

Collaboration with Tech Companies: Lasting change requires cooperation of technology providers and social media platforms. Stricter age verification systems and design changes at the source are needed, rather than placing usage responsibility on children. By remodeling platforms, risk of unsupervised penetration of digital content can be mitigated so children may still be allowed safe, and age appropriate engagement on social media.

As Karnataka moves into this new territory, one thing is certain – the intention is noble. However, the execution of such a ban will require a fine balance of protection and empowerment, as it attempts to re-imagine childhood experiences in an age where the “virtual” and the “real” are meshed together. Whether this becomes a guiding model for the rest of the country, will depend entirely on how thoughtfully it is carried out.

Karnataka’s proposed ban is a bold first step, but its true impact will depend on how parents, teachers, and policymakers align on this, because healthy childhoods thrive not on restrictions, but through resilience, support, guidance, and strong offline connections that nurture growth and belonging.

Iron deficiency is one of the most common nutritional problems among women, but in the juggle between professional and household responsibilities, a majority of women tend to ignore their health. However, the detecting the mild symptoms in the beginning can help boost treatment and improve quality of life for women, said experts, while stressing the need for timely screening, ahead of International Women's Day.

International Women's Day is observed globally on March 8 every year.

According to health experts, in a month, around 5 out of 10 women between the ages of 30 and 45 visit doctors with complaints such as persistent weakness, headaches, and tiredness. These symptoms are often linked to iron deficiency and put women at risk of developing anemia.

“Iron deficiency is a matter of concern among women, because the symptoms, such as fatigue and weakness, are neglected until the condition becomes serious,” said Dr. Upasana Garg, Regional Technical Chief, Apollo Diagnostic Mumbai.

Dr. Garg said iron deficiency can be detected through simple blood tests that will be advised by the expert and will play a pivotal role in early diagnosis and timely treatment.

These include tests for

• Hemoglobin levels -- are carried out to measure the amount of oxygen-carrying protein in the blood and indicate if a woman has anemia

• Serum ferritin and iron levels -- to gauge the amount of stored iron in the body and help detect iron deficiency even before anemia develops

• A complete blood count (CBC) -- to measure red blood cells, including their size and number, which checks if the body is producing healthy blood cells.

Anemia In Women

Anemia is a major public health concern, mainly affecting young children, pregnant and postpartum women, and menstruating adolescent girls and women.

The World Health Organization (WHO) estimates that 40 percent of all children aged 6–59 months, 37 percent of pregnant women, and 30 percent of women 15–49 years of age worldwide are affected by anemia.

Anemia occurs when there isn’t enough hemoglobin in the body to carry oxygen to the organs and tissues.

In severe cases, anemia can cause poor cognitive and motor development in children. It can also cause problems for pregnant women and their babies. It is often caused by a lack of iron in the blood.

“Iron is a necessary mineral which helps the body to produce hemoglobin, a protein in red blood cells that carries oxygen to different parts of the body. When the body does not have enough iron, it is unable to produce healthy red blood cells. This condition is known as iron deficiency or iron deficiency anemia,” said Dr. Ritu Agrawal, Gynecologist, Zynova Shalby Hospital, Mumbai.

Dr. Agrawal said that women are more likely to experience iron deficiency when compared to men.

The major reason is blood loss during menstruation, and women who have heavy periods are at a higher risk.

During pregnancy, when the body needs extra iron to support the growing baby, the risk of anemia increases in the mother.

Other factors include poor diet, skipping meals, and not eating enough iron-rich foods.

Early Screening And Treatment

The common symptoms of anemia in women include:

constant tiredness,

weakness,

pale skin,

shortness of breath,

dizziness,

headaches,

hair fall

difficulty concentrating

frequent infections due to reduced immunity

Dr. Agrawal said that 50 percent of women tend to ignore early symptoms of anemia.

“In a month, around 5 out of 10 women between the ages of 30–45 visit with complaints such as persistent weakness, headaches, and tiredness, which are often linked to iron deficiency and put them at risk of developing anemia. If iron deficiency is not treated in time, it can lead to several health complications,” she added.

Severe anemia can also lead to heart-related problems, such as irregular heartbeat or shortness of breath.

The experts noted that detecting iron deficiency on time and initiating immediate treatment is necessary for women's better health.

Management of iron deficiency includes

• improving diet and taking iron supplements as advised by any expert
• Have iron-rich foods like spinach, beans, lentils, nuts, and dates
• Vitamin C–rich foods, such as oranges and lemons.
