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.

The boom in GLP-1 weight loss drugs is not only affecting the obesity market but also reshaping the beauty industry. Changes in consumer behaviour among those who use GLP-1 drugs is evident as people may see differences in their appearance after drastic weight loss. This phenomenon has prompted global beauty companies to explore products for people experiencing changes in their appearance after losing weight.

French cosmetics giant L’Oréal is among the companies exploring this emerging market segment. Its CEO, Nicolas Hieronimus, said the increasing use of these medications was affecting beauty and skincare consumption, compelling the company to explore products that address concerns like sagging skin after extreme weight loss.

“The rise in their (GLP-1 drugs) use was having an impact on beauty consumption and skin care consumption in particular,” Hieronimus said during an investor call on October 22, after the company's third-quarter results came out.

The development mirrors an important shift in the beauty industry as weight loss medications like Ozempic, Wegovy and Zepbound become more widely used for weight management.

Amid the growing market for these drugs, companies are now seeing increased demand for treatments that help changes in facial volume, skin firmness and elasticity after weight loss.

However, the science behind ‘Ozempic face’ is far more complicated than the name suggests. Experts say these changes are generally associated with losing facial fat during weight loss, especially when it happens rapidly.

What is ‘Ozempic Face’?

‘Ozempic face’ is an informal term for facial changes that occur after rapid and substantial weight loss. It is marked by hollowing around the cheeks and temples and more noticeable wrinkles or sagging skin.

GLP-1 medicines, including semaglutide and tirzepatide, act on appetite regulation, helping people feel fuller for a long time and reducing their calorie intake. As a result, some people lose a substantial amount of weight over a short period.

Beauty Companies Respond to GLP-1 Boom

Apart from L’Oréal, Swiss skincare company Galderma and Brazilian cosmetics group Natura are also seeing similar demands from consumers experiencing changes in their facial skin after medicated weight loss.

L’Oréal has said that it is testing products on people using GLP-1 medications. Its SkinCeuticals range also has products intended to address concerns such as skin sagging, according to Hieronimus.

“We have products in SkinCeuticals that are made to work alongside GLP-1 drugs and address their side effects, such as skin sagging and other related issues. It is very integrated,” he said.

Galderma, in which L’Oréal holds a 20% stake, has assessed some of its existing aesthetic treatments for changes due to GLP-1 use. Its portfolio includes Sculptra, an injectable that stimulates collagen, and Restylane, a range of hyaluronic acid-based dermal fillers.

Anne-Cecile Chevrier, Galderma's global head of injectable aesthetics, described the concerns that experts are seeing among consumers. “Sagginess is a concern, loss of firmness is a concern, some hollowness can be of concern and dullness can be a concern,” she said.

Can Skincare Products Reverse ‘Ozempic Face’?

The expansion of this market does not necessarily mean that skincare products can reverse facial changes due to rapid weight loss.

The skin has several layers, and topical products act on the skin's surface. Facial fat loss happens when fat accumulated beneath the skin melts off. Skincare products cannot simply replace this process.

Dr Graeme Glass, a plastic and craniofacial surgeon and aesthetic director at British beauty brand LYMA, explained the limitations of topical treatments. “They can't reposition the deep fat pads of the face. There is a limit to what these things can do,” he said.

Moisturisers and other products may help improve hydration, texture and the appearance of fine lines. But these benefits should not be confused with correcting sagging skin.

Treatments like fillers and collagen injectables may address these concerns directly, but they involve different risks, costs and clinical considerations.

Avani Sinha, MD, and FACE endocrinologist and program director of the Northwell Health Division of Endocrinology, Diabetes and Metabolism fellowship told Women's Health Magazine that it is important to take care of nutrition and muscle-building to "fill up spaces where you are losing that skin laxity".

“We are what we eat, we are what we do,” she said, stating that protein intake is especially important on a GLP-1. She suggested aiming 0.8 to 1.8 grams per kilogram of body weight.

Sinha also recommended staying hydrated along with strength training to build muscle. “You build up that muscle, you're going to fill up those spaces where you're losing that skin laxity,” she said.

US journalist Norah O’Donnell recently spoke about the importance of early skin cancer detection a decade after being diagnosed with melanoma, the most dangerous form of skin cancer.

She said her experience changed her outlook towards sun protection. She also shared advice related to skin cancer from her dermatologist, Dr Elizabeth Hale.

According to CBS News, O’Donnell recalled that it was during a routine dermatology appointment when Hale noticed two concerning spots on her back.

A biopsy confirmed melanoma, but the cancer was detected early and removed before it could spread.

O’Donnell said she now seeks shade wherever she can find, wears UV-protective clothing and regularly reapplies broad-spectrum sunscreen when spending time outdoors. She also reflected on her past exposure to sunburns and tanning salons.

Detecting Melanoma Early

Melanoma develops in the cells that produce melanin, the pigment responsible for skin colour. Although it accounts for a smaller proportion of skin cancer cases, it is responsible for an alarming share of skin cancer deaths.

Hale emphasised that early detection can make a considerable difference. “Even though it only accounts for 5% of new cases of skin cancer, it’s responsible for more than 75% of skin cancer-related deaths,” she said.

She also spoke about the importance of getting suspicious spots examined rather than waiting for them to become more noticeable and serious.

“There have been major advances in melanoma treatment, but it’s still really best to get your skin checked because when melanoma is caught early it has greater than a 99% five-year survival. But once it spreads, that survival rate goes down precipitously,” Hale said.

Tanning Beds And Sunburns Increase Melanoma Risk

Speaking about skin cancer risks related to tanning beds and sunburns, Hale said melanoma cases have been increasing among women in their 20s and 30s.

“It is directly related to exposure to tanning beds and to sunburns,” she said.

According to the Skin Cancer Foundation, using tanning beds before 35 could increase melanoma risk by 75%.

Hale also warned against the growing trend of deliberately seeking a tan through prolonged, unprotected sun exposure.

“There really is no such thing as … a safe, healthy tan,” she said.

A tan is not simply a cosmetic appeal. As Hale explained, it denotes “DNA damage” that may contribute to cancer later in life.

What Does Her Dermatologist Recommend?

Hale recommends regular skin examinations to nab suspicious skin changes early. She advises people to discuss their individual cancer screening needs with a dermatologist, especially if they have a family history of skin cancer.

Sun protection is another essential part of prevention. Hale recommends using a broad-spectrum sunscreen with SPF 30 or higher and reapplying it every two hours when spending extended periods outdoors.

Her advice on choosing sunscreen is straightforward: “the best sunscreen is the one you’ll actually use”.

Non-Negotiable Sunscreen Ritual

As per the Johns Hopkins Medicine, wearing sunscreen is the easiest and the best ways to protect your skin's appearance and health at any age. It recommends to use it regularly to prevent sunburn, skin cancer, and premature aging.

While everyone needs sun exposure to produce vitamin D, unprotected exposure to the sun's UV rays can cause damage to the eyes, skin, and the immune system.

To protect, apply 1 ounce of sunscreen throughout your body. To protect your face and neck, you will need about half a teaspoon of sunscreen.

Experts also believe that as long as the sunscreen is at least SPF 30 and is water-resistant, it does not matter what order you apply your skin care products. While some people find it is easiest to work with bare skin, some do it at the end.

Protective clothing and seeking shade can provide additional protection, especially during prolonged outdoor activities.

Arthritis is sometimes treated like a normal part of getting older. Yet it can show up in many age groups. It can also limit how freely someone moves. That can affect daily independence and overall comfort.

Some people think arthritis care always means an operation, like joint replacement. In reality, the path to care is wider. What happens next depends on symptoms, which joint is affected, a person’s age, how active they are, and their general health.

Early-Stage Arthritis: Why Physiotherapy And Exercise Matter

Where the disease is in its early stages or is perceived to be mild, treatment will begin in a very low-key manner. This will involve physiotherapy and exercise. Where necessary, losing excess body weight can be beneficial. Minor changes in daily activities will decrease stress. Doctors will prescribe medication depending on the situation. Here, the main objective is to alleviate symptoms and maintain function. It will not be the initial step and will only be considered where appropriate.

In case arthritis is severe, pain and stiffness will persist for a long period of time. Performing simple activities becomes difficult. Even walking will become challenging. Sleep may also be affected. When this happens, it helps to check again. Doctors can use exam findings and imaging to see how much the joint has changed. They can also review whether non-surgical care is working as expected.

How Doctors Decide On The Right Treatment

Good arthritis care is about choosing the right path for the right person. Timing matters too. It begins with a close look at symptoms and a clear diagnosis. Sometimes it also means getting scans when they are needed. After that, the plan should rely on what the best research shows.

Treatment should be set up with rehab in mind. The aim is to fit the person, not just the label on the chart. One person may do well with physical therapy and simple habit shifts. Another person may need a procedure, mainly when a joint is badly worn.

Why Early Arthritis Management Matters

The main goal is easier daily comfort and better movement. Just as important, it should help someone keep their independence. It is also not only about chasing the newest option.

People should not wait until pain makes normal life hard. When they seek help early, it can be easier to see what is driving the joint pain. It can also help show how far the arthritis has gone. With that in hand, a care plan can be built with more clarity.

When care starts early and matches the person, many can stay active longer. They may also better protect joint function and keep it working well for more time.
