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.

Fever is one of the body's most common warning signals. In most cases, particularly among children, it is caused by a simple infection and resolves within a few days. However, when fever keeps returning repeatedly, follows a pattern, or occurs alongside other concerning symptoms, it may signal an underlying health condition that requires medical attention.
Dr. Hemalata Arora, Director of Internal Medicine at Nanavati Max Super Speciality Hospital, Mumbai, told HealthandMe that a recurring fever refers to repeated episodes of elevated body temperature that are separated by days, weeks, or even months during which a person feels completely well.
While recurrent fevers can sometimes result from common viral infections, especially in children exposed to school environments, daycare settings, or seasonal illnesses, persistent or unexplained episodes warrant further investigation.
The expert stated that understanding the pattern of fever is often one of the most important clues in determining the cause.
Dr. Diksha Goyal, Consultant in Internal Medicine at Marengo Asia Hospitals, Gurugram, told HealthandMe that a recurrent fever can occur when body temperature rises to 38°C or higher and reappears after improving or occurs intermittently over time.
Several medical conditions may cause recurring fever, including:
1. Chronic Infections such as tuberculosis (TB), urinary tract infections
2. Autoimmune Diseases
3. Immune System Disorders
4. Cancers, particularly blood-related cancers
5. Certain Viral Infections
While recurrent fever is not always dangerous, the experts emphasize that certain accompanying symptoms require prompt medical evaluation.
Dr. Arora notes that urgent attention is needed if recurring fever is associated with:
Dr. Goyal added that persistent cough, swollen lymph nodes, and unexplained body pain can also indicate an underlying condition requiring medical treatment.
These symptoms may point toward serious infections, immune system disorders, blood-related diseases, cancers, or inflammatory conditions in which the body's defense system triggers repeated inflammation without a clear infection.
Another important warning sign is a fever that continues to recur despite treatment. According to Dr. Arora, repeated courses of antibiotics without a confirmed diagnosis should raise concern. In some cases, medications themselves can trigger fever, making a detailed medication history an important part of the evaluation.
The goal is not to panic but to seek timely medical assessment. Check for swollen lymph nodes, rashes, signs of infection, or evidence of systemic inflammation.
The experts noted that early medical evaluation can help identify the underlying cause, prevent complications, and ensure appropriate treatment. With timely diagnosis and proper management, many causes of recurrent fever can be effectively treated, allowing individuals to maintain their health and daily activities.

Tobacco use remains a global epidemic and one of the leading preventable causes of death worldwide. Despite a strong desire among many users to quit, relapse rates remain alarmingly high. A new study by researchers at the All India Institute of Medical Sciences (AIIMS), New Delhi, suggests that yoga could be a valuable tool in helping people quit tobacco.
To evaluate the effectiveness of yoga in tobacco cessation, researchers led by Dr Gautam Sharma, Department of Cardiology and Centre for Integrative Medicine and Research, AIIMS, conducted a meta-analysis of five randomized controlled trials (RCTs) published up to September 2024.
The review included adults aged 18 years and older who used any form of tobacco, excluding vaping products. Participants were randomly assigned to yoga either as a standalone intervention or alongside conventional cessation treatments.
The primary outcome assessed was the 7-day point prevalence abstinence (7PPA), a standard measure of smoking cessation. Secondary outcomes included quality of life, depression, anxiety, and mood states.
The findings suggest that “yoga may serve as a moderately effective intervention for tobacco cessation, with an estimated effectiveness of around 50 per cent”, the team said in the paper.

Researchers found that active yoga styles such as Hatha, Vinyasa, and Iyengar yoga improved abstinence rates by helping reduce stress, depression, and negative emotions often associated with tobacco withdrawal.
Pranayama, or yogic breathing exercises, was found to reduce cravings and negative affect, making it easier for participants to cope with withdrawal symptoms.
The review also highlighted the importance of addressing psychological factors linked to tobacco addiction, including perceived stress, anxiety, depression, and emotional distress—all of which are known contributors to relapse.
While some studies reported stronger psychological benefits than others, overall evidence suggests yoga may support emotional well-being during the quitting process.

Researchers believe yoga may help manage tobacco addiction through several biological mechanisms.
Nicotine stimulates nicotinic cholinergic receptors in the brain, triggering the release of neurotransmitters that produce pleasurable and rewarding effects. During withdrawal, stress-related hormones increase, leading to anxiety, cravings, and emotional discomfort.
Yoga appears to counter these effects by shifting the body from a state of sympathetic nervous system dominance ("fight or flight") to parasympathetic dominance ("rest and digest").

This shift may reduce activity in the hypothalamic-pituitary-adrenal (HPA) axis, lower cortisol levels, and decrease stress hormone production, helping individuals better manage cravings and withdrawal symptoms.
The team also noted that controlled breathing techniques can significantly influence emotional regulation, with voluntary breath control accounting for substantial variations in emotional states such as anger, fear, and joy.
India alone has more than 270 million active tobacco users. Given the widespread use of smokeless tobacco in the region—and the limited effectiveness of standard cessation medications for these users—yoga could offer an accessible, culturally familiar, and low-cost complementary approach, the researchers stressed.
While the results are encouraging, researchers also cautioned that larger and more standardized studies are needed.

Every day, hospitals care for patients whose survival depends on a simple yet irreplaceable resource—donated blood. A mother experiencing severe bleeding after childbirth, a child with thalassemia requiring regular transfusions, a cancer patient undergoing chemotherapy, or a victim of a road traffic accident may all rely on timely access to safe blood.
Despite medical advances, blood remains unique. It cannot be manufactured or artificially replicated. It can only come from healthy individuals who choose to donate. This makes blood donation one of the most vital contributions a person can make to healthcare and society.
It is important to understand that the impact of a single donation extends far beyond what most people imagine.
When a person donates whole blood, it is separated into components—red blood cells, platelets, and plasma. Each component serves a different purpose. Red blood cells carry oxygen and are essential in treating anemia and blood loss. Platelets help control bleeding and are critical for patients undergoing chemotherapy. Plasma contains proteins and clotting factors required for managing bleeding disorders.
Because these components can be used independently, a single donation has the potential to benefit multiple patients with different medical conditions. One act of donation can therefore support several lives.
A common misconception is that blood is needed only during emergencies or disasters. In reality, the demand for blood is constant. Patients with chronic conditions such as thalassemia require regular transfusions throughout their lives. Cancer treatments, major surgeries, organ transplants, complicated pregnancies, and trauma care all depend on a steady and reliable blood supply.
Unlike many medical resources, blood components have limited shelf lives. Platelets can only be stored for a few days, and red blood cells have a defined storage period. This means blood stocks must be continuously replenished. A stable blood supply cannot be created overnight—it depends on regular and voluntary donations throughout the year.
The safest and most reliable blood supply comes from voluntary donors who give blood without expectation of reward. However, maintaining this supply is an ongoing challenge. It requires not only recruiting new donors but also encouraging previous donors to return.
Many individuals who donate once do not return, often due to lack of awareness, time constraints, or fading motivation. Yet every regular donor begins as a first-time donor. A positive first donation experience plays a key role in building long-term commitment.
Hospitals, workplaces, and community organizations play a crucial role in promoting donation through awareness campaigns, outreach programs, and well-organized blood donation drives. Sustained engagement is essential to ensure that donors remain connected to this life-saving cause.
Blood donation is not just a medical act—it is a powerful expression of social responsibility. Most donors never meet the individuals they help, yet they donate willingly to support someone in need. This anonymous act of giving reflects compassion, empathy, and a shared sense of humanity.
People are motivated to donate for many reasons. Some are driven by altruism and the desire to help others. Others are influenced by personal experiences, community values, or encouragement from family and peers. Awareness campaigns and social engagement can also play a significant role in shaping attitudes towards donation.
Understanding these motivations is important because it helps design more effective strategies to encourage both first-time and repeat donors.
Despite its importance, many eligible individuals hesitate to donate due to fear or uncertainty. Concerns about pain, weakness, or safety are common. However, blood donation is a carefully regulated process conducted by trained healthcare professionals.
Donors undergo screening to ensure that the procedure is safe for both themselves and the recipient. The donation itself takes only a short time, and most people can resume normal activities soon afterward. Efforts to improve donor comfort and reduce anxiety have further enhanced the overall donation experience.
For many first-time donors, the greatest takeaway is a sense of satisfaction and pride in having contributed to saving lives.
One of the greatest challenges in maintaining a stable blood supply is ensuring a continuous flow of new donors. As regular donors age or become ineligible, new volunteers are needed to sustain the system.
Encouraging first-time donors is therefore critical. With the right experience and awareness, a first-time donor can become a lifelong contributor, potentially helping dozens of patients over the years. Simple follow-up communication and continued engagement can significantly improve donor retention.
Families, educational institutions, workplaces, and healthcare providers all have a role to play in encouraging individuals to take this first step.
Blood is more than a medical resource—it is a gift that cannot be bought, manufactured, or stored indefinitely. It represents hope, survival, and the generosity of one human being towards another.
Behind every successful surgery, every recovering patient, and every saved life, there is often an unseen donor whose contribution made that outcome possible.
A single donation may take only a few minutes, but its impact extends far beyond a single individual. It supports families, strengthens healthcare systems, and builds a culture of care and compassion within communities.
The message is simple: if you are eligible, consider donating. Your one unit of blood may help many—and could make the difference between life and loss for someone in need.
