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.

Concerns around fertility and vaccines often surface when people plan a family, and the HPV vaccine is no exception. Many women and men worry that getting vaccinated today could affect their ability to conceive later in life. Medical experts, however, say this fear is misplaced. According to fertility specialists, there is no evidence linking the HPV vaccine to reduced fertility. In fact, the vaccine may play a quiet but important role in protecting reproductive health over the long term.

Does The HPV Vaccine Affect Fertility?

The short and clear answer is no. The HPV vaccine does not negatively affect fertility in women or men. Dr. Madhu Patil, Consultant and Fertility Specialist at Motherhood Fertility and IVF, Sarjapur, Bangalore, explains that there is no scientific proof showing the vaccine causes fertility problems of any kind.

She notes that concerns often arise from misinformation rather than medical data. Extensive research and global vaccination programmes have consistently shown that people who receive the HPV vaccine do not experience reduced chances of conceiving in the future.

How HPV Infection Can Threaten Future Fertility

While the vaccine itself does not harm fertility, an untreated HPV infection can. HPV is the leading cause of nearly all cervical cancer cases. As per Dr Patil, “treatment for cervical cancer often involves procedures such as cone biopsy or LEEP, which can weaken the cervix. In more advanced cases, radiation or chemotherapy may be required.”

These treatments can reduce a woman’s ability to conceive and, in some cases, make it difficult to carry a pregnancy to full term. By preventing HPV-related cancers in the first place, the vaccine helps preserve the reproductive system and lowers the risk of fertility-compromising treatments later in life.

Why The HPV Vaccine Supports Reproductive Health

Dr. Patil points out that the HPV vaccine should be viewed as a protective measure rather than a risk. By stopping high-risk HPV strains from causing cancer or precancerous changes, the vaccine helps maintain cervical health. A healthy cervix and reproductive system are key factors in natural conception and safe pregnancies.

In this way, the vaccine indirectly supports fertility by reducing the likelihood of medical interventions that could interfere with reproductive function.

When Should the HPV Vaccine Be Taken?

Health experts recommend starting HPV vaccination at ages 11 or 12. At this stage, the immune response is strongest, and the vaccine offers protection well before any potential exposure to the virus. Dr. Patil strongly encourages parents to consult a gynaecologist and consider timely vaccination for their children.

That said, adults who missed vaccination earlier can still benefit. Many women and men receive the vaccine later in life after discussing it with their doctor.

Why Men Should Also Get The HPV Vaccine

The HPV vaccine is not only for women. Dr. Patil stresses that men should also be vaccinated, as HPV can cause cancers and genital warts that affect sexual health. Vaccination in men also reduces transmission to partners, adding another layer of protection for couples planning a family.

By limiting the spread of HPV, vaccination helps safeguard the reproductive and sexual health of both partners.

There is no evidence that the HPV vaccine reduces fertility. On the contrary, it helps prevent cancers and medical treatments that can threaten the ability to conceive or carry a pregnancy. Experts advise speaking with a gynaecologist, understanding the benefits, and making an informed decision based on medical facts rather than fear.

A three-year-old girl was left partially blind after what first seemed like a routine ear infection was later diagnosed as a life-threatening brain tumour. As per Express UK, Chloe Kefford was rushed to A&E when she started experiencing car sickness and balance problems. Doctors initially diagnosed her with an ear infection and sent her home with antihistamines. But as Chloe’s condition worsened, her parents insisted on further testing, which revealed a tumour affecting her optic nerve.

Ear Infection Symptoms Masked A Life-Threatening Diagnosis

Chloe, from Formby, Merseyside, underwent open brain surgery and faced three-and-a-half years of treatment, including proton beam therapy last year, after experiencing two relapses. Proton beam therapy uses high-energy protons to precisely target the tumour, limiting damage to surrounding healthy tissue.

Open Brain Surgery And Years Of Intensive Treatment Followed

Now nine years old, Chloe has been honoured with a special award from Cancer Research UK for her bravery throughout her treatment. She received her initial care at St George’s Hospital in London and The Royal Marsden, before being transferred to Alder Hey in Liverpool.

Proton Beam Therapy Used After Cancer Relapsed Twice

Chloe’s mother, Nikki, 38, recalled that the family had been planning a move from Surrey to Merseyside before Chloe fell ill. As per Express UK, she said: “The house was already sold and we were planning our new life by the beach when Chloe became ill. Then we ended up moving and having to isolate for months. She relapsed not long after we moved and had more chemotherapy, then she rang the bell in April last year, but unfortunately, she relapsed again in July. So, we were supposed to be going on holiday to Disneyland in Paris and instead we went to Manchester for six weeks for Chloe to have proton beam therapy.”

Nikki added: “She is partially sighted now and has no peripheral vision; one eye is particularly badly affected. The main aim now is to preserve what eyesight she has left. We’re hopeful that the recent targeted treatment has got the cancer once and for all. She’s on steroids at the moment and is being monitored with three-monthly scans. She’s still in recovery and struggles with fatigue from the treatment, but we hope she’ll have a bit more energy soon. She’s our little ray of sunshine.”

Each year, around 400 children and young people in the North West are diagnosed with cancer. Advances in treatment and research are helping make therapies more effective and less harmful. Alder Hey Children’s Hospital in Liverpool is one of several centres across the UK taking part in pioneering clinical trials offering innovative new treatments.

In 2018, Cancer Research UK launched the Children’s Brain Tumour Centre of Excellence, supported by TK Maxx. The virtual centre brings together international experts in children’s brain tumour research to transform how treatments are developed. Every child nominated for a Star Award receives this recognition, which is endorsed by celebrities including JoJo Siwa and Pixie Lott.

Cancer Research UK spokesperson Jemma Humphreys said: “After everything Chloe’s been through, it’s been an absolute privilege to celebrate her incredible courage with a Star Award.”

People experiencing certain symptoms are being urged to stay at home as a highly contagious virus spreads quickly across England. Fresh figures from the UK Health Security Agency show a 47% rise in cases during the first two weeks of 2026. This sudden jump has led the agency to remind the public about basic hygiene steps that play a key role in limiting the spread. Data suggests that norovirus is affecting people aged 65 and above the most, and although overall activity remains within normal seasonal levels, there has been a noticeable increase in outbreaks in hospital settings.

The latest UKHSA surveillance update also points to falling levels of flu, COVID-19, and RSV in the opening week of the year. While all winter virus levels are currently where they would be expected for this time of year, people are being encouraged to continue following simple precautions to help keep infections on a downward path.

What Is Norovirus?

Norovirus Symptoms

Common symptoms of norovirus include:

• Nausea.
• Vomiting.
• Diarrhoea.
• Stomach pain.

You may also experience:

• Headache.
• Fever.
• Body aches.

Symptoms usually develop between 12 and 48 hours after exposure and typically last for one to three days.

Doctors Report New Symptoms Of Norovirus

Both flu and norovirus can behave unpredictably, with case numbers rising and falling throughout the season. This makes simple preventive steps especially important. For illnesses affecting the stomach or respiratory system, such as norovirus, regular handwashing remains one of the most effective measures.

Health experts stress that alcohol-based hand sanitisers do not work against norovirus. Washing hands thoroughly with soap and warm water, along with cleaning surfaces using bleach-based products, is far more effective in reducing the spread. Good ventilation indoors can also help limit the transmission of respiratory viruses like flu. Anyone who develops symptoms is advised to stay at home whenever possible.

If going out cannot be avoided, wearing a face covering may help, particularly when around people who are more vulnerable.

Amy Douglas, Lead Epidemiologist at the UKHSA, said, according to the Mirror: “We have seen a clear rise in norovirus cases in recent weeks, particularly among people aged 65 and over, alongside an increase in hospital outbreaks. Although levels are still within what we would normally expect, there are simple actions people can take to stop norovirus spreading further.

“Washing hands with soap and warm water and cleaning surfaces with bleach-based products are key steps. Alcohol gels do not kill norovirus, so they should not be relied on alone.

“If you have diarrhoea and vomiting, do not return to work, school, or nursery until 48 hours after symptoms have stopped, and avoid preparing food for others during this time. If you are unwell, please stay away from hospitals and care homes to protect those most at risk from infection.”
