HIV vs. AIDS: What You Should Know About These Commonly Confused Terms

Updated Dec 3, 2024 | 11:43 AM IST

SummaryWorld AIDS Day, observed on December 1st, raises awareness about HIV/AIDS, promotes education, supports those affected, and advocates for global action to eliminate the pandemic, emphasizing early detection, treatment, and prevention.
World Aids Day

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.

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.

Hemophilia: Why Bone Health Needs Attention From Childhood

Updated Oct 29, 2026 | 04:00 PM IST

SummaryChildhood and adolescence are critical for building peak bone mass, making early intervention important for long-term musculoskeletal health, said health experts.

People with hemophilia face an increased risk of poor bone health due to recurrent joint and muscle bleeds, joint damage and reduced physical activity. Experts told HealthandMe that preventing bleeds from childhood, alongside adequate nutrition, appropriate exercise and regular assessment, can help protect bone health throughout life.

Globally, an estimated 836,000 people have hemophilia, including approximately 284,000 with severe hemophilia. In India, the World Federation of Hemophilia (WFH) reported nearly 28,000 diagnosed and registered patients as of 2026, including more than 24,000 with Hemophilia A. However, the estimated prevalence could be as high as 1,36,000, suggesting many cases remain undiagnosed or misdiagnosed.

Childhood and adolescence are critical for building peak bone mass, making early intervention important for long-term musculoskeletal health, said health experts.

How Hemophilia Can Affect Bone Health

Hemophilia is an inherited bleeding disorder caused by a deficiency of clotting factor VIII (Hemophilia A) or factor IX (Hemophilia B). It primarily affects males, while women are often carriers.

Repeated bleeding into joints can cause chronic pain, joint damage, deformity and reduced mobility. Muscle bleeds can further restrict movement, limiting participation in physical activities that help maintain bone strength.

“Bone health begins in childhood, but protecting it is a lifelong commitment. In people living with hemophilia, recurrent joint and muscle bleeds, reduced physical activity and other risk factors can contribute to poor bone health and an increased risk of osteoporosis,” Dr. Varun Bafna, associate professor in the Department of Hematology at Chhatrapati Shahu Maharaj Government Medical College, Kolhapur, told HealthandMe.

Why Prophylaxis Matters

Prophylaxis involves preventive treatment to reduce bleeding episodes rather than treating bleeds only after they occur. Regular factor prophylaxis can help prevent recurrent joint bleeds, preserve joint function and support mobility.

“Regular factor prophylaxis helps prevent repeated joint bleeds and preserve joint function. That protection can support mobility, an important contributor to bone health,” Dr. Hitha B, associate professor and haematologist in the Department of Medicine at Government Medical College, Kozhikode, told HealthandMe.

She advised patients to discuss breakthrough bleeding or difficulties accessing treatment with their healthcare team so their treatment plan can be reviewed.

Dr. Bafna said consistent prophylaxis can also support muscle strength and safer participation in physical activity.

“Prophylaxis is not just about preventing bleeding today; it is an important part of protecting long-term musculoskeletal health and quality of life at every age,” he noted.

How to Protect Bone Health From Childhood

Experts recommend an individualized approach based on age, joint health, mobility and other risk factors. Key measures include:

  • Calcium and vitamin D: Ensure adequate intake through diet and discuss supplementation with a healthcare professional when needed.
  • Appropriate physical activity: Weight-bearing exercises suited to individual joint health can help maintain bone strength, with guidance from the care team.
  • Physiotherapy: Tailored rehabilitation can help maintain muscle strength, mobility and joint function.
  • Regular assessment: Periodic evaluation can identify bone-health concerns and determine whether further investigations are needed.
  • Consistent prophylaxis: Adhering to prescribed preventive treatment can reduce bleeding episodes and help protect joints.

A Multidisciplinary Approach to Lifelong Care

Hematologists, physiotherapists and other healthcare professionals can help patients and families integrate preventive treatment, rehabilitation, nutrition and appropriate physical activity into an individualized care plan.

Early intervention and consistent care can help preserve joint function, mobility and quality of life as people with hemophilia grow older.

World Stroke Day: What Is BE FAST? Stroke Warning Signs To Watch For

Updated Oct 29, 2026 | 03:00 PM IST

SummaryOn World Stroke Day, we look at stroke symptoms like sudden dizziness, blurred vision, facial drooping and slurred speech that can be easy to dismiss. Doctors explain the BE FAST warning signs, why immediate medical attention is crucial, and how recognising symptoms early could improve recovery outcomes. In India, call 112 for emergency assistance if a stroke is suspected.

A stroke rarely announces itself loudly. A sudden wobble, a blurry eye or a slightly lopsided smile is easy to ignore. But in a stroke, minutes decide how much of the brain survives.

On World Stroke Day, doctors want everyone to know one simple tool: BE FAST.

What Doctors Say

Dr. Abhinav Gupta, Director of Neurology at Sarvodaya Hospital, Greater Noida West, and Dr. Atampreet Singh, Senior Director and Head of the Institute of Neurosciences at ShardaCare, Healthcity, told HealthandMe, “Knowing the early warning signs of a stroke can shorten the road to full recovery,” they said.

The problem, they added, is that “a stroke’s symptoms can be easy to dismiss as minor inconveniences, like being tired or having weak muscles.”

What Is BE FAST?

BE FAST was developed by Intermountain Healthcare as an adaptation of the American Stroke Association’s FAST model, according to a Frederick Health handout. The doctors break it down like this:

  • B – Balance: “Unsteady feeling or sudden lack of muscle control and dizziness can be a warning sign of a stroke.”
  • E – Eyes: “Don’t overlook loss of sight in one or both of a person’s eyes, sudden blurring, or double vision.”
  • F – Face: “Ask the person to smile. Unevenness or droopiness on one side of the face can be a sign.”
  • A – Arms: “Have the person raise both of their arms. If the person has difficulty holding one arm up or has unusual arm weakness, get emergency help.”
  • S – Speech: “Sudden lack of ability to talk, inability to understand what others are saying, or slurred words, can be signs of a stroke.”
  • T – Time: “If one of these symptoms occur out of the blue, then call emergency services. When the emergency operators are on the line, let them know what symptoms have presented.”
On the cause, the doctors said: “A stroke is caused by the disruption of blood flow to part of the brain. When the brain is deprived of the necessary blood supply, cells start to die.” They named high blood pressure, diabetes, high cholesterol, smoking and heart disease as common causes. But they noted that “strokes can occasionally occur even in the absence of obvious risk factors.”

Why “Time” Matters The Most

Time is not a symptom. It is a reminder to hurry. Duke Health, citing the American Stroke Association, says to call for help even if the symptoms go away. Weill Cornell Medicine, citing the same group, says never to drive yourself to hospital.

The Frederick Health handout adds that you should note when the symptoms began. UChicago Medicine estimates that about 1.9 million brain cells die every minute in a stroke caused by a large blocked artery.

India’s biggest problem is delay in seeking medical treatment.

An ICMR study of 34,792 stroke cases at 30 hospitals between 2020 and 2022 found that only 5.3% of patients reached hospital within the first hour, according to South First. Nearly four in ten waited more than 24 hours. Down To Earth, reporting on a Lancet Neurology study, says India had over 1.25 million new stroke cases in 2021, up 51% since 1990.

If you see even one sign, don’t wait for the others. Call 112, India’s single emergency number, which also covers the 108 ambulance service, according to Factly. Say what you see and when it began.

From Cracked Heels to Numbness: Common Foot Problems That Shouldn’t Be Ignored

Updated Oct 29, 2026 | 01:31 PM IST

SummaryCracked heels, persistent foot pain, tingling and numbness may signal more than everyday wear and tear. From fungal infections and nerve damage to diabetes-related complications, recognising common foot problems and their warning signs can prevent serious complications.
From Cracked Heels to Numbness: Common Foot Problems That Shouldn’t Be Ignored

Many people track their steps, sleep and heart rate with a precision that once seemed unusual. The feet behind those steps rarely get the same attention, hidden as they are inside shoes all day.

A crack, an ache or a patch of numbness is easily put down to the weather, age or an ill-fitting pair of sandals. Yet some complaints reach a clinic only after they begin to interfere with everyday life.

Symptoms That Are Easy to Explain

Cracked heels are a good example, because they are so common that most people treat them as a cosmetic matter and reach for a moisturiser. That is usually reasonable, although a deep fissure that bleeds or keeps reopening gives bacteria a way into the skin and is worth having examined.

Heel pain often has a musculoskeletal cause and tends to respond to rest and supportive footwear, but pain that lingers for weeks points to something more specific. Numbness gives the least warning of all, since it can arise from nerve compression, poor circulation, nutritional deficiencies or diabetes, and because it does not hurt, an injury can go unnoticed for days.

Why Weekly Measurement Matters

When a wound does develop, understanding whether it is actually healing becomes just as important as recognising the early warning signs. Researchers who monitor wounds over time know that appearance alone does not always tell the full story.

What a Recent Case Report Showed

A 2025 case report in the Journal of the Foot & Ankle followed two adults with long-standing diabetes and neuropathic plantar ulcers for twelve weeks, with wound area quantified by digital planimetry. One wound, treated with a graft of decellularised human dermis, shrank by 80 percent by week four and had fully epithelialised by week eight.

The other, managed with gauze-based moist wound care, reduced by 7.8 percent at week two, grew by 21.6 percent between weeks three and five, and reached a 68.6 percent reduction by week twelve without closing. No adverse events were recorded in either patient during the twelve weeks.

Reading the Evidence Carefully

The report is descriptive, and two patients cannot settle questions about any treatment. The lesson that carries beyond the clinic is more modest, since progress is easier to judge when it is tracked against a timeline.

Asking How Long, Not How Bad

For readers, the message is to pay attention not just to how serious a symptom looks, but also to how long it has lasted and whether it is changing. Cracks that repeatedly reopen, persistent heel pain and spreading numbness deserve medical attention.

For people with diabetes, any new foot wound should be assessed promptly rather than waiting to see whether it improves on its own.
