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.

India is better prepared to deal with potential Hantavirus outbreaks due to the healthcare infrastructure and quarantine systems established during the COVID-19 pandemic, according to Dr NK Ganguly, former Director General of the Indian Council of Medical Research (ICMR).
In an exclusive interview with HealthandMe, Dr Ganguly said that while isolated cases of Hantavirus have appeared in India in the past, especially in crowded peri-urban and urban settings in Kerala, large-scale outbreaks have largely been reported in countries such as China, Argentina, the UK, and the US.
Dr Ganguly said that India's healthcare system significantly improved after the deadly COVID pandemic.
“India is overprepared in a way that during the COVID-19, our system, even at the district level or in much more rural settings, got established,” he said.
He pointed out that hospitals now have access to ECMO, BPAP systems, ventilators, and oxygen management facilities to curb the spread in case of an outbreak.
Dr Ganguly also mentioned the availability of antiviral drugs and experimental vaccine efforts that could potentially be explored for hantavirus treatment. “There are some crude vaccines which are made here also,” he said.
He added that India’s quarantine systems and public health drills developed during COVID-19 would also help contain future outbreaks.
“I think India will be okay because of the sheer transmission dynamics of this virus,” he said.
Hantavirus is a zoonotic disease that primarily gets transmitted through contact with infected rodents or exposure to their urine, droppings, and saliva, though rare cases of person-to-person transmission have also been reported.
According to the World Health Organization (WHO), 11 cases — including three deaths — have been confirmed so far. However, additional suspected and confirmed cases are likely to emerge across countries.

The One Health approach is critical in understanding and containing outbreaks like hantavirus, Dr Ganguly said.
The One Health approach, which integrates human health, animal health, and environmental monitoring, is also crucial to target the emerging infectious diseases, he noted.
Further, the noted microbiologist stressed the importance of strengthening surveillance across humans, animals, and the environment.
He explained that disease surveillance requires collaboration between bird specialists, forest experts, environmental scientists, and mammologists, especially for tracking zoonotic infections such as avian flu and hantavirus.
“In avian flu, birds follow special migration routes, so we needed bird specialists, forest experts, environmental experts, and mammologists,” Dr Ganguly said.
The expert also highlighted the growing challenge posed by shrinking spaces between humans and animals and the role of antimicrobial resistance (AMR) in emerging disease threats.
“Animal health is equally important. We need to maintain them, track their movements, and do surveillance,” he said.
Dr Ganguly also warned that rising temperatures and shrinking boundaries between humans and animals could increase the risk of future infections.
“It is an environmental infection. With the rise of temperature, more hantavirus infections occur,” he told HealthandMe.
Calling surveillance one of the most critical tools in outbreak prevention, he urged India to strengthen monitoring systems for animals, vectors, and humans alike.
“We need to set up a dedicated surveillance for hantavirus in India, and we need to track hantavirus,” he said.
Dr Ganguly explained that to date, hantavirus cases in India have been detected accidentally during testing for respiratory infections or flu-like illnesses using advanced panel-based diagnostic systems.
“Like now these days, what happens is that when you are getting respiratory infection or flu-like symptoms, they put up a test system which is known as bio-fire or a thing like that which identifies 26 panels and gives the CT scoring of that, so from there, hantavirus emerged,” he said.
He added that India should strengthen surveillance tools and continue monitoring infections in animals, vectors, and humans alike.

Prateek Yadav (38), the son of late Samajwadi Party founder Mulayam Singh Yadav, died due to a massive blockage in the blood vessels of the lungs, leading to a collapse of the heart and respiratory system, as revealed in the postmortem examination report.
According to the autopsy findings, the provisional cause of death was recorded as “cardiorespiratory collapse due to massive pulmonary thromboembolism.” In simple terms, doctors said a large blood clot had blocked blood flow to the lungs, causing his heart and breathing to fail.
An embolism is any object (clot, fat, air, tissue) traveling through the bloodstream that becomes stuck, blocking blood flow. A thromboembolism is a specific type of embolism where that travelling object is a piece of a blood clot (thrombus) that has broken off from its original site.
It is a life-threatening condition that happens when a blood vessel in the lungs is blocked by a blood clot.
The common symptoms may include:
The blood clot starts in a deep vein in the leg and travels to the lung in most cases. Rarely, the clot forms in a vein in another part of the body, noted Mayo Clinic. When a blood clot forms in one or more of the deep veins in the body, it is called a deep vein thrombosis or DVT.
Other symptoms of pulmonary embolism include:

Meanwhile, Karnataka's Planning and Statistics Minister, D. Sudhakar (66), passed away after a prolonged battle with a lung infection.
The most common lung infections that people experience are pneumonia, bronchitis, tuberculosis, influenza-related infections, and severe viral illnesses.
Experts noted that these lung infections cause fluid or pus to fill the air sacs, which prevents oxygen from entering the bloodstream.
"What may initially appear as a routine cough, fever, or chest infection can progress to severe pneumonia, respiratory failure, sepsis, or permanent lung damage,” Dr. Vikas Mittal, Director - Pulmonologist, CK Birla Hospital, Delhi, told HealthandMe.
Warning signs include
Dr. Nikhil Rajvanshi, Consultant - Paediatric Pulmonology, Rainbow Hospital, Delhi, told HealthandMe that children may be more at risk of pulmonary infections as they can become dangerous quickly because their lungs and immune systems are still developing.
Common illnesses such as bronchiolitis, pneumonia, influenza, and other viral infections may rapidly lead to breathing difficulty, low oxygen levels, dehydration, and respiratory distress. Infants, premature babies, malnourished children, and those with asthma or congenital disorders are at higher risk of complications.

US President Donald Trump's attempt to clarify the meaning of "sea" while discussing drug smuggling has again raised concerns of dementia.
While the 79-year-old President rambled between “sea and see” in the middle of discussing drug problems in the US, social media went rife with the rumor of his cognitive decline.
"Drugs coming by sea meaning coming by water. A lot of people don’t know what I mean by sea. They think I mean vision. I’m talking about sea like the sea," he said. He was speaking at the White House, while hosting law enforcement officials for a dinner in the Rose Garden in celebration of National Police Week.
His comments were called out by social media as his apparently worsening cognitive capabilities.
"When he says 'a lot of people' he means 'me.' His cognitive issues are a crisis," one social media user declared, while another admitted, "He’s getting worse."
Trump has spoken on sea and see, during a maternal healthcare event last week, where he also referred to himself as the “father of fertility.”
Earlier, speaking at the White House Small Business Summit, Trump said he has taken the Montreal Cognitive Assessment three times and “aced each one,” claiming a doctor told him it was the first time they had seen a perfect score, The Daily Beast reported.
The US President said he answered the test questions easily, suggesting he is cognitively in good condition—a claim that critics have repeatedly questioned.
“The first question is very easy,” he said. “You have a lion, a bear, an alligator, and a—what’s another good…? A squirrel. Which is the squirrel?” He added that the difficulty increases as the test progresses. “By the time you get to the middle, they’re very tough.”
However, the test’s creator, Canadian neurologist Ziad Nasreddine, has challenged Trump’s claims. “It wasn’t designed to be a test of IQ,” he told nine.com.au. “It was designed to assess normal cognitive performance.”

A group of medical experts, including neurologists, psychiatrists, and other physicians, has sounded the alarm over what they’ve described as Trump’s deteriorating mental health.
The experts have not specifically examined Trump face-to-face. But, they analyzed Trump's statements and behaviors over the past year, and stated that he’s “mentally unfit” and must be removed from office “with the greatest urgency” amid the escalating tension around the world, according to their statement published in The BMJ.
“It is our professional opinion that they (Trump's statements) reflect a rapidly worsening, reality-untethered, increasingly dangerous decline,” the experts said.
They also listed some of Trump’s observable serious medical issues, such as “Marked deterioration in cognitive functioning, evidenced by disorganized and tangential speech, rambling digressions, factual confusions, unexplained sudden changes of course in strategic matters, both national and international, episodes of apparent somnolence during critical public proceedings.”

What The White House Says
The White House has continued to say that Trump remains in strong health.
In October 2025, White House physician Captain Sean Barbabella said the president “continues to demonstrate excellent overall health,” AOl.com reported.
"President Trump’s sharpness, unmatched energy, and historic accessibility stand in stark contrast to what we saw during the last administration when Democrats and other lunatics intentionally covered up Joe Biden’s serious mental and physical decline from the American people,” White House spokesman Davis Ingle was quoted as saying to The Daily Beast.
