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.

A GP has warned that people can catch Covid more than once in a short span, including while they are still unwell from a previous infection. In some cases, this may even involve picking up two strains of the virus at the same time, a situation doctors are calling “double Covid”.

Doctor Warns of ‘Double Covid’ as UK Cases Rise

New figures from the UK Health Security Agency show confirmed Covid cases have risen by 11 per cent. In the week leading up to January 9, 51 deaths were recorded and more than 500 people were in hospital with the virus.

Can You Catch Covid Twice at the Same Time?

Speaking to the BBC, GP Dr Nish Manek said it is possible to be infected again while still dealing with ongoing symptoms, including long Covid. She explained that having long Covid does not provide immunity against reinfection.

According to Dr Manek, protection from a previous infection or vaccination reduces over time. New variants are also better at evading the immune system, making repeat infections more likely.

Why Long Covid Does Not Protect You

As a result, someone managing long Covid symptoms may still catch Covid again. A fresh infection can trigger a relapse of symptoms or slow down recovery.

She added that a positive test may reflect either the same strain or a new variant. In both cases, it is still Covid and should be taken seriously.

Vaccines Still Reduce Severe Illness

Dr Manek stressed that vaccination remains important. While vaccines may not fully prevent infection, they significantly reduce the risk of severe illness and hospitalisation.

She said Covid continues to change and remains present in the community. Simple protective steps still matter, including testing when unwell, wearing masks in crowded indoor settings, and staying up to date with vaccinations.

Which Covid Variants Are Circulating Now

Latest Covid Symptoms to Watch For

Doctors say symptoms linked to current variants often affect the upper respiratory tract and can feel similar to a bad cold or flu.

Commonly reported symptoms include a very painful sore throat described as feeling like razor blades, a hoarse voice with swollen glands, blocked or runny nose, sneezing, and extreme tiredness. Fever, a persistent cough, and body aches are still widely seen.

Loss of taste or smell is now reported far less often than during the early stages of the pandemic.

Who Is Eligible for a Covid Vaccine in the UK

The UK has moved to a targeted vaccination approach, focusing on those most at risk of serious illness.

The current winter vaccination programme is coming to an end. The final date to receive this dose is January 31, 2026. You are eligible if you are aged 75 or over, live in a care home for older adults, or are aged six months or older and immunosuppressed due to medical treatment or long-term conditions.

A spring booster programme has been confirmed for 2026. Appointments are expected to open in late March, with vaccinations starting from April 13. Eligibility criteria remain the same as the winter programme.

How To Book Your Covid Vaccine?

Doctors continue to urge those eligible to get vaccinated while doses are still available.

A lace-like pattern appearing on the skin may sometimes point to blocked arteries. Health experts warn that this netted discoloration can, in certain cases, be linked to damage in tissues and organs.

Heart and circulatory diseases remain the leading cause of death worldwide, claiming close to 18 million lives every year. This group includes serious conditions such as stroke, coronary artery disease, and heart failure.

An Unusual Skin Pattern That Could Signal Artery Blockage

In the UK, cardiovascular disease is responsible for around one quarter of all deaths. Because of its scale and severity, recognising warning signs early can save lives.

Most people are familiar with common symptoms like chest pain. What is less widely known is that heart-related problems do not always announce themselves clearly. Some signs are subtle and can appear in unexpected places, including the skin.

What Is Livedo Reticularis?

The American Academy of Dermatology highlights one particular skin pattern that may be linked to heart and blood vessel problems. A blue or purple, net-like discoloration on the skin can sometimes indicate reduced blood flow or a blocked artery.

This condition is known as livedo reticularis. It is believed to occur when small blood vessels near the skin tighten suddenly or when circulation close to the skin becomes uneven.

When the Pattern Is Usually Harmless

In many cases, livedo reticularis is not a cause for concern. Cold temperatures are a common trigger, and the pattern often fades once the skin warms up. Certain medications can also produce this effect without posing a serious health risk.

According to the dermatology body, some people notice the pattern when they feel cold, only for it to disappear as their skin warms. When medication is responsible, it is generally considered harmless.

When It May Point to a Serious Condition

In some situations, the same skin pattern can be linked to a condition known as cholesterol embolisation syndrome. This happens when tiny arteries become blocked by cholesterol particles.

Such blockages can interfere with blood supply and lead to damage in tissues and organs. For this reason, experts stress the importance of medical evaluation to rule out any underlying or undiagnosed disease.

When to See a Doctor

The Mayo Clinic advises seeking medical advice if the mottled skin does not fade with warmth or if it appears alongside other worrying symptoms. You should also consult a doctor if painful lumps or sores develop in the affected area, if you already have a condition that affects blood flow to your limbs, or if you have a connective tissue disorder and notice new skin changes.

Doctors also caution that a similar-looking condition, called livedo racemosa, is more often linked to serious underlying illnesses.

Other Warning Signs of Heart Disease

Skin changes are only one possible clue. Other symptoms linked to heart disease include chest discomfort, pain or weakness in the arms or legs, shortness of breath, irregular heartbeats, dizziness, unusual tiredness, and swelling in the limbs.

If any of these symptoms feel concerning or persistent, it is important to speak to your GP for further advice.

A diagnostic report from Madhya Pradesh’s Satna district has sparked shock and concern after it incorrectly stated that a 47-year-old man had a uterus. The incident has raised serious questions about negligence and accuracy in medical testing.

The report was issued to Niranjan Prajapati, chairman of the Uchehra Nagar Panchayat, who had gone for a sonography after experiencing abdominal pain and swelling. Instead of clarity about his condition, he received a report that appeared to describe female reproductive organs, including an inverted uterus.

How the Error Came to Light

Prajapati underwent the ultrasound at a diagnostic center on Station Road in Satna on January 13. Initially, he did not closely examine the report and followed the prescribed treatment. However, when his condition did not improve, he sought further medical advice.

“I was sick and had stomach pain. I first got treatment in Unchahara and then went for sonography in Satna,” Prajapati said. “I did not pay much attention to the report at first and took medicines, but there was no relief.”

He later visited a doctor in Jabalpur, where the mistake was clearly identified. “The doctor told me straight that this report cannot belong to me,” Prajapati recalled. “I said the report has my name on it, but it mentioned a uterus. That is when I realized something was seriously wrong.”

Questions Over Diagnostic Negligence

The report not only listed a uterus but also described its position, despite the patient being male. Medical experts say such an error goes far beyond a minor clerical mistake.

A senior doctor, speaking on condition of anonymity, said incorrect diagnostic reports can have serious consequences. “A wrong sonography report can mislead treatment, cause unnecessary stress to the patient, and in some cases become life-threatening if doctors act on false findings,” the expert said.

Attempts to seek clarification from the diagnostic center did not yield answers. Dr Arvind Saraf, associated with the facility, declined to comment on the incident, adding to concerns about accountability and quality checks.

Complaint Filed, Health Department Responds

Following the incident, Prajapati filed a formal complaint at the local police station. The matter has also been taken up by the Health Department.

Chief Medical and Health Officer of Satna, Dr Manoj Shukla, confirmed that an investigation is underway. “This complaint has come to my notice. We are examining the report thoroughly. If any irregularity or negligence is found during the investigation, appropriate action will be taken,” he said.

Officials are expected to review how the report was generated and whether standard diagnostic protocols were followed.

What Is Sonography?

Sonography, also known as ultrasound, is a commonly used imaging test that uses sound waves to create images of internal organs. It does not involve radiation and is generally considered safe. However, experts stress that accuracy and proper verification are crucial, as reports directly guide diagnosis and treatment.

The incident has once again highlighted the need for stricter checks and accountability in diagnostic services, especially when errors can directly affect patient health and trust in the medical system.
