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.

While HPV vaccines are most known for preventing cervical cancer, a top US doctor says they can also help curb the rising incidence of head and neck cancers.

According to Mikkael A. Sekeres, Chief of the Division of Hematology and Professor of Medicine at the Sylvester Comprehensive Cancer Center at the University of Miami, Human papillomavirus (HPV) — the same sexually transmitted virus that can infect the genital area and lead to cervical cancer — is now the greatest risk factor for head and neck cancer.

Writing in The Washington Post, Sekeres noted that HPV accounts for about 30 per cent of oropharyngeal cancer worldwide.

HPV is believed to be responsible for the recent rise in head and neck cancers, which include malignancies affecting the mouth and throat (oral cavity and pharynx), voice box (larynx), sinuses and nasal cavities, and salivary glands.

Sekeres said the US records about 60,000 new cases of head and neck cancers each year, while the global incidence is expected to rise by 30 per cent by 2030.

What Are The Risk Factors?

The expert noted that men develop oral cavity and pharynx cancers at approximately 2.5 times the rate of women.

Major risk factors include:

• Tobacco use, including smoking, secondhand smoke and smokeless tobacco
• Chewing areca nut, also known as betel quid
• Heavy alcohol consumption
• HPV infection

The Centers for Disease Control and Prevention (CDC) estimates that the high-risk HPV subtypes most associated with head and neck cancers are detectable in the mouths of 4 per cent of adults aged 18 to 69.

While a pap test detects early-stage cervical cancer in women, no such test exists for penile, anal, or head and neck cancers in men, which can worsen their survival rate.

HPV Vaccination Best Prevention Strategy

Thus, Sekeres said: “The best way to prevent the most common types of HPV is through vaccination, with two doses of the vaccine recommended for children at age 11 or 12, or starting as early as 9 years and up to age 26 for those who missed it as a child".

He noted that although the vaccine is approved for use up to age 45, it is generally less beneficial after age 26 because many individuals may have already been exposed to HPV. However, doctors can help determine whether vaccination may still be beneficial for adults.

Earlier this year, the European Cancer Organization also urged broader HPV vaccination regardless of gender.

“HPV affects everyone, regardless of gender. It can lead to cancers of the cervix, mouth and throat, anus and penis. This is why universal protection is so important,” the organization said in a social media post.

HPV Vaccine Can Boost Cancer Risk

A 2026 study published in JAMA Oncology found that boys and men who received the HPV vaccine between the ages of 9 and 26 were nearly 50 per cent less likely to develop cancers of the head and neck, esophagus, anus, or penis.

The findings, based on data of more than 510,000 boys and men, highlight the importance of vaccinating all children and adolescents against HPV, said Taito Kitano, first author of the study and a researcher at Nara Prefecture General Medical Center in Japan.

“Children, adolescents, parents and health care workers should be more informed about the expected benefits of the HPV vaccine, not just cervical cancer,” Kitano said.

FIFA has launched a groundbreaking initiative aimed at advancing research and knowledge to boost health and performance of female athletes.

The FIFA Female Health and Performance Project comes ahead of the tenth edition of the FIFA Women's World Cup, which is scheduled to take place in Brazil next year.

The initiative aims to provide specialist, science-based educational resources tailored to the preparation and development of female athletes. It also seeks to close long-standing gaps in understanding the unique health and performance needs of female players, many of whom still lack access to the scientific data needed to support their development and optimize performance.

“FIFA’s aim is to optimize every female footballer’s health, well-being and performance, and to improve knowledge around women and girls in football at every level of the game,” said Sarai Bareman, FIFA’s Chief Women’s Football Officer.

“Collectively, we can do so much more to better support our growing number of female players and ensure they are trained, supported and understood according to their specific needs as women.”

Why Is The Initiative Significant?

A study analyzing 5,261 research articles published in sport and exercise science journals between 2014 and 2020 found that only 34% of study participants were female, while just 6% of sport science research focused exclusively on women.

Only 8% of elite female athletes have sufficient knowledge about how the menstrual cycle may affect training and performance.

Many training methodologies, workload models and performance benchmarks used in sport have historically been derived from male athlete data, requiring female athletes to adapt to systems that may not accurately reflect their physiological characteristics.

What Will The Project Achieve?

The initiative is designed to provide a comprehensive understanding of the female athlete, her individual needs, her environment and the tailored support required to optimize health and performance.

The educational modules cover universal topics in football and elite sport science, including sleep, recovery, strength and conditioning, all examined through the lens of the female athlete.

Female-specific topics such as physiology, pregnancy, postpartum health and menopause are also included.

Four separate learning levels — from “Introduction” to “Integrated” — provide tailored information for a wide range of audiences, from sports professionals to members of the general public.

In addition to improving access to knowledge and education, the initiative aims to break taboos, normalize language, eliminate social stigma, encourage open communication and establish a supportive environment in which female athletes can thrive.

“We need to normalize conversations around female health and embrace this, using it to our advantage instead of ignoring it or being fearful of discussing it,” Bareman added. “It is not a weakness; it is a strength.”

Key areas covered by the project include:

• Female physiology
• Reproductive years
• Menstrual health tracking
• Pregnancy and postpartum health
• Fertility
• Menopause
• Pelvic health
• Nutrition
• Recovery
• Sleep
• Strength and conditioning
• Screening and profiling
• Injury and injury prevention

Who Will Benefit?

Available to all through FIFA’s Training Centre platform, the FIFA Female Health and Performance education modules are the result of collaboration with leading experts to generate, curate and apply the scientific evidence underpinning the program.

All 211 FIFA Member Associations will have access to specialised, peer-reviewed, science-based information through 13 tailor-made educational modules.

UK-based journalist Emma Barnett said it took 21 years to receive a diagnosis of endometriosis, a chronic condition in which tissue similar to the uterine lining grows outside the womb.

The condition, which causes severe pain and other complications, affects one in 10 women. However, diagnosis remains difficult and is often dismissed as merely “painful periods”.

“It’s a disease that has outwitted doctors and researchers around the world. No one knows what causes it. No one knows how to cure it. At least 1 in 10 women are staggering about with it,” Barnett shared in a post on Instagram.

“Endometriosis may not typically kill women, but it’s a living death for many. It is a silent medical emergency,” she added.

The 41-year-old BBC journalist said: “It’s a scandal it takes nearly 10 years to be diagnosed — in my case 21 years.”

Living With Debilitating Pain

There is currently no cure for endometriosis. Available treatments include hormone therapy, predominantly the contraceptive pill, to manage symptoms, or surgery, including hysterectomy in severe cases.

“I’ve been suffering from the condition — in which tissue similar to the womb lining, that’s meant to leave your body, grows and builds outside the uterus — since my periods started at the age of 10. But it would be more than 20 years until I’d be diagnosed at 31, after two years of trying to get pregnant naturally, which meant more than 20 years of enduring excruciating, bone-grinding pain without ever having a label for it,” she wrote in Women's Health magazine.

She described the pain “as a drilling sensation from my pelvis that travels down my legs — making them feel as though I can’t lift them to go up the stairs. Sometimes, the hurt spreads to my arms or chest, and comes with crippling nausea and loss of appetite. I also run cold; freezing even. It’s like someone turned the heating off in my body”.

A Documentary To Expose A Neglected Disease

Recognizing that many women experience similar struggles, Barnett made a new documentary film "Emma Barnett: Fighting Endometriosis" in which she speaks with women, including doctors, researchers and even politicians about their experiences with endometriosis, highlighting a neglected disease that has no known cure.

Through the documentary, Barnett hopes to raise awareness of the condition, improve public understanding, and draw attention to the long delays many women face in receiving a diagnosis.

“One of the reasons I have made a film about endometriosis is that I want people to understand it is not just ‘painful periods’. It’s a system-wide inflammatory condition where tissue similar to the lining of the uterus grows outside of it, causing agonizing pain. I am hoping to boost public understanding of that, and beyond merely being able to pronounce it,” she wrote in The Independent.

“It’s very hard to make something invisible visible, but what I am trying to do with this film is bring the invisible into light and show that this is a silent emergency.”
