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.

Norovirus appears to be increasing after a 57 percent jump in hospital admissions linked to the sickness bug last week. Figures from the NHS show that an average of 567 hospital beds were occupied each day by patients suffering from diarrhoea and vomiting. Although this number remains well below last winter’s peak, the sudden rise over just one week has raised concerns that norovirus infections could soon climb further.
Experts believe the return of children to school and more indoor contact following the Christmas break may be helping the virus spread.
Jason Murphy, head of pharmacy at Chemist4U, as per The Mirror, said the virus is often underestimated. “Norovirus spreads far more easily than people realise. Even a very small amount can make you ill, and it can stay on surfaces for several days. As cases continue to climb, it’s important to move beyond basic hygiene and take more focused steps to protect yourself and others. Many people think norovirus is a short-lived illness, but it’s very persistent and passes on easily.”
Murphy added that pharmacists tend to approach norovirus from two angles. “We focus on stopping it from spreading and on helping the body cope while the infection passes. There’s no treatment that kills the virus itself, but there are ways to ease symptoms and lower the risk of problems like dehydration.”
Treat it as a hard-to-kill infection – Norovirus is classed as a non-enveloped virus, which means alcohol hand gels and many everyday cleaners do not work against it. Washing hands with soap and warm water removes the virus physically, while bleach can neutralise it on surfaces.
Use the right cleaning products – Choose disinfectants that clearly state they are virucidal or effective against non-enveloped viruses. If this is not mentioned, the product is unlikely to kill norovirus.
Get bleach dilution right – Bleach needs to be mixed correctly. If it is too diluted, it will not kill the virus. If it is too strong, it can irritate the skin and lungs. Always ventilate the room well and follow the instructions on the label.
Treat vomiting as contamination – In healthcare settings, vomiting is handled as a form of airborne exposure. Clean beyond the visible mess, air out the space properly, and assume nearby soft furnishings may also be contaminated.
Create isolation at home – If possible, give the unwell person their own bathroom, towels, and bin. This mirrors hospital infection control measures and helps limit the spread to others.
Focus on rehydration – Dehydration is the most serious risk linked to norovirus. Electrolyte drinks are more effective than water alone because they replace lost salts as well as fluids.
Take fluids slowly – Sip small amounts every five to ten minutes instead of drinking large volumes at once. This helps reduce vomiting and allows the body to absorb fluids better.
Pain relief – Once fluids are staying down, paracetamol is the safest option for fever, headaches, and muscle aches. Ibuprofen should be avoided if you are dehydrated or vomiting frequently, as it can irritate the stomach and strain the kidneys.
Be careful with anti-diarrhoea medicines – Drugs such as loperamide can slow diarrhoea, but this is not always advised because diarrhoea helps flush the virus out. These medicines may be used briefly in specific situations, such as essential travel, but should not be given to children or used if there is a fever or blood in the stool.
Help with nausea – For severe sickness, a pharmacist can recommend anti-nausea treatments. If vomiting continues, a GP may prescribe medication to help control symptoms so fluids can be kept down.
Eat gently when ready – Once your appetite comes back, start with plain foods like toast, crackers, bananas, or rice. Avoid rich, spicy, or dairy-heavy foods until you feel better.
Rest as part of recovery – The immune system clears norovirus on its own. Getting enough rest supports recovery and helps prevent further complications.

The takeaway coffee cup in your hand may be releasing a sea of microplastics into your body every time you take a sip, a new study reveals.
Microplastics are essentially fragments of plastic that are between 1 nanometer and 5 millimetres wide and can found in water, soil and the air. Experts estimate that about 2.7 million tonnes of microplastics seeped into the environment in 2020, an estimate expected to double by 2040.
These fragments carry toxic chemicals and can disrupt internal biological processes, leading to inflammation, cell death, organ dysfunction, heart attacks and reproductive issues in humans. Scientists have also found links between microplastics and cancer.
While researchers have long claimed that microplastics can enter the human body through contaminated food and water, a new Australian study suggests it can also enter through hot coffee cups.
Xiangyu Liu, study co-author and research fellow at School of Environment and Science and Australian Rivers Institute, Griffith University, Nathan, said this was due to heat.
The team conducted a a meta-analysis on existing research and analyzed data from 30 peer-reviewed studies. During this time, they focused on how common plastics such as polyethylene and polypropylene behave under different conditions, primarily temperature.
As the temperature of the liquid inside a container increased they noticed that the release of microplastics generally increases too. In the studies reviewed, reported releases ranged from a few hundred particles to more than 8 million particles per litre, depending on the material and study design.
Interestingly, 'soaking time' or the amount of time the drink sits in the cup was not a consistent driver, suggesting that leaving a hot drink in a plastic cup for a long time is not as important as the initial temperature of the liquid when it first hits the plastic.
After testing nearly 400 different cups, they found that if someone drinks '300 millilitres of coffee in a cup made of polyethylene per day, they could ingest 363,000 pieces of microplastic particles every year', according to Liu
The team recommends using a reusable cup made of stainless steel, ceramic, or glass, as these materials do not shed microplastics for hot drinks. If you must use a disposable cup, its is better to drink out of a plastic-lined paper cup as they shed fewer particles than pure plastic cups, though neither is microplastic free.
They also advise not pouring putting boiling liquids directly into plastic-lined containers. Telling the barista to make your morning coffee slightly cooler before it hits the cup can reduce the physical stress on the plastic lining and lower overall exposure.

A dangerous, drug-resistant fungus has infected more than 7,000 people across 27 US states, including Mississippi, in 2025, federal health data shows. The infection, known as Candida auris, is classified as an “emerging infectious disease,” after doctors and public health experts noted a steady rise in cases since 2019, according to specialists at the Cleveland Clinic.
As of December 20, Mississippi had reported 108 cases of the fungal infection, based on figures from the Centers for Disease Control and Prevention. Here is what you need to know about Candida auris cases in Mississippi.
Treating it is challenging because the organism can adapt to medications meant to eliminate it, health experts note. C. auris mainly affects people with serious underlying health problems and those using invasive medical devices such as ventilators, feeding tubes, or catheters, according to the CDC.
The fungus spreads through contact with contaminated surfaces and objects and can remain on a person’s skin or other body areas even when no symptoms are present. Experts say healthcare workers and visitors are not considered at risk of becoming infected.
Symptoms of Candida auris are not always noticeable, but when they do appear, they may include the following, according to the Cleveland Clinic:
According to CDC data as of December 20, cases have been reported in the following states:
Candida auris, often referred to as a “superbug fungus,” is continuing to spread worldwide and is becoming increasingly resistant to both antifungal drugs and the human immune response, researchers at the Hackensack Meridian Center for Discovery and Innovation said in a review published in early December.
The findings support earlier CDC warnings that labeled C. auris an “urgent antimicrobial threat,” making it the first fungal pathogen to receive that classification, as case numbers have climbed sharply in the United States, especially in hospitals and long-term care facilities.
The review, published in the journal Microbiology and Molecular Biology Reviews, explains why the fungus is so difficult to control and highlights how outdated testing methods and limited treatment options have failed to keep pace. The research was led by Dr. Neeraj Chauhan of Hackensack Meridian CDI in New Jersey, Dr. Anuradha Chowdhary from the University of Delhi’s Medical Mycology Unit, and Dr. Michail Lionakis, head of the clinical mycology program at the National Institutes of Health.
In their statement, reported by Fox News, the researchers emphasized the urgent need to develop new antifungal drugs with broad effectiveness, improve diagnostic tools, and explore immune-based and vaccine-related treatments to better protect high-risk patients.
