What Is The Difference Between HIV And AIDS?

HIV vs AIDS

With the US pausing its funds in the healthcare sector, along with UN<span>AIDS</span>, a global threat for <span>HIV</span> cases has risen. It has led to panic, fear, and confusion in many African countries who are the hardest hit by AIDs. In fact, official data states that this move could lead to a 6 times jump in HIV cases. While HIV and AIDS are being discussed all over the news now, not many know the difference between the two.

Human immunodeficiency virus or HIV is a diseases that weakens a person's immune system by attacking CD4 cells which help the body fight off infection. 

Whereas AIDS, which stands for acquired immunodeficiency syndrome happens when the HIV advances.

The first known case of HIV-1 infection in human was detected in 1959, from a blood sample of a man in Kinshasa, Democratic Republic of Congo. However, the source of his infection is not known. The genetic analysis of the blood sample revealed that HIV-1 may have stemmed from a single virus in late 1940s or early 1950s. 

In the US, this virus existed from mid 1970s. Between 1979-81 rare types of pneumonia, cancer and other illnesses were reported to doctors in Los Angeles and New York, and a number of the patients were men who had sex with other men. The conditions reported in those patients were not found in a person with healthy immune system. In 1982, healthcare officials began to use the term acquired immunodeficiency syndrome, that is how it was named AIDS. The DC Health website mentions that this term was used to describe the occurrences of opportunistic infections. It was in 1983 that the scientists finally discovered the virus that caused AIDS. The virus was first named HTLV-III/LAV (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee. This name was later changed to HIV (human immunodeficiency virus).

<h4>Countries With Highest HIV Rates</h4>

As per the World Population Review, the top 10 countries with the highest HIV rates as of 2023 are:

<ul><li>Eswatini at 27.5%</li><li>Lesotho at 20.5%</li><li>Botswania at 19.7%</li><li>South Africa at 16.6%</li><li>Mozambique at 11.8%</li><li>Zimbabwe at 11.7%</li><li>Namibia at 11.5%</li><li>Zambia 11%</li><li>Malawi at 7.5%</li><li>Uganda at 5.6%</li></ul>

Then there are the countries with the most number of people living with HIV as per 2023:

<ul><li>South Africa: 7,700,000</li><li>India: 2,500,000</li><li>Mozambique: 2,400,000</li><li>Nigeria: 2,000,000</li><li>Tanzania: 1,700,000</li><li>Uganda: 1,500,000</li><li>Kenya: 1,400,000</li><li>Zimbabwe: 1,300,000</li><li>Zambia: 1,300,000</li><li>Brazil: 1,000,000</li></ul>

HIV progresses and becomes AIDS in three stages:

<strong>Acute HIV infection:</strong> It has flu-like symptoms in the host and starts to destroy body's CD4 T lymphocyte cells. 

<strong>Chronic HIV:</strong> While the HIV levels are lower, it is still persistent. Infected individuals may have no symptoms and the risk of transmission to others is also diminished to a certain level. The World Population Review mentions: Patients on treatment plans may have virus levels so low as to be undetectable, making the risk of transmission nearly zero, and live at this stage for decades.

<strong>Acquired Immunodeficiency Syndrome: </strong>This is the third stage of HIV infection, if left untreated, it can progress to AIDS, where your body is no longer to fight off any infections.

How Smoking, Alcohol, And Vaping Are Quietly Hurting Women’s Fertility

how smoking, alcohol, and vaping are quietly hurting women’s fertility

Being the leading cause of death worldwide, <span>cancer</span> diagnoses can change the trajectory of a person’s life. New cancer stats reveal that an estimate of 2,041,910 new cancer cases will be diagnosed in the US, and about 600,000 have been estimated to die due to the disease. As you may know, cancer is a generic term for a lot of different diseases that affect our health. A malignant <span>cancer diagnosis</span> means that there is a rapid growth in abnormal cell growth which can affect various parts of your body. 

According to the World Health Organization, cancer causes nearly 1 in 6 deaths globally and had accounted for 20 million deaths in 2020. The question remains, has the advancement in research and public education helped lower cancer cases or recognized any concerning patterns? 

New information from Cancer Research UK, looking at 50 years of health data, shows both good and bad news about cancer. On the one hand, the number of deaths from cancer has gone down by more than one-fifth, which is a positive sign. However, the number of people being told they have cancer has actually gone up by 50%, showing a worrying increase in new cases. 

<h2>More Young People Getting Cancer </h2>

One of the most concerning things we're seeing is how much more young people, under the age of 50, are getting cancer. Specifically, for those between 20 and 49 years old, cancer rates have shot up by 23% since the 1990s. Scientists are now working hard to understand why this is happening and what's causing this significant jump in cancer cases among younger individuals. Several factors are being explored as likely contributors to the rise in early-onset cancers: 

<h4>Obesity, Poor Diet, and Inactivity </h4>

These lifestyle choices are strongly linked to the increase. Research into the rise of colon cancer among young people, for instance, revealed that more than a third of those studied were obese. It has been observed that individuals developing cancer at a younger age tend to have significantly higher rates of obesity compared to those diagnosed later in life. 

The food we eat greatly affects our gut health. It's suggested that outside elements like microplastics or chemicals could be altering this balance, potentially contributing to cancer development. Experts stress how important it is to start healthy eating and exercise habits early. There's also a warning not to forget that certain drinks can be just as risky as unhealthy processed and sugary foods. 

It's interesting to note that smoking is probably not the reason for the increase in cancer among young people. Experts have actually seen a drop in cancers linked to smoking across almost all age groups. This suggests that while smoking is a known cause of cancer, its decreasing popularity means it's not behind the current rise in cases among younger generations. 

Despite more young people getting cancer, Cancer Research UK's report highlights that we are currently in a very positive time for cancer treatment. Thanks to advancements, one in two people diagnosed with cancer are now expected to live for at least 10 years. This is a huge improvement from the 1970s, when only one in four patients reached that milestone, showing great progress in saving lives.

A Routine Sinus Rinse With Tap Water Led To Woman's Death After Brain-Eating Amoeba Infection

a routine sinus rinse with tap water led to woman's death after brain-eating amoeba infection

If you have ever had a <span>migraine</span> then you would know that it is not just a <span>headache</span>, but it comes in phases. It starts with you being sensitive to all noise, smell, and even taste, feeling a bit dizzy, and losing out on your energy. Then there is a throbbing pain, this is when you know your migraine has reached its peak. 

<h4>What Are The <span rel="noindex">Stages Of Migraine</span>?</h4>

There are four main stages of migraine, which starts from predrome, aura, headache, and then postdrome. 

This stage is like a warning stage where there may be certain physical and mental changes. These include feeling tired, excessive yawning, food cravings, changes in your mood. You may feel low or irritated. Your body feels dehydrated and you might feel thirsty, have stiffness around your neck and may pass more urine. 

This happens to a third of people with migraine, notes The Migraine Trust. There are various neurological symptoms that happens in this stage, which includes changes in sight. This means, one may see dark spots, coloured spots or sparkles, often described as stars and zigzag lines. There could also be numbness, feeling like pins and needles on your body, you may also feel weakness, dizziness, and have problems with speech and hearing. 

The Migraine Trust notes that aura is the result of wave of nerve activity that spreads over the brain, it is also known as cortical spreading depression. When this electrical wave spreads, the nerves fire in an abnormal way and this range of reversible neurological symptoms develop. 

This can last from five minutes to 60 minutes. 

As per the American Migraine Foundation, the headache phrase of a migraine attack is characterized by pain on one or both sides of the head. This phase lasts from several hours to up to three days. 

This phase can vary from person to person. While some can experience mild pain, for others it could be a debilitating pain. 

The pain, in this phase, also shifts from one side of the person's head to other. In this phase, doing everyday activity like walking, turning on the lights, or any slight change, movement, sensory actions can aggravate the pain. 

This phase is also called "migraine hangover". This happens during the end of headache phase. The American Migraine Foundation notes that not everyone experiences this phase, however, it occurs in most cases, in about 80% of people. 

In this phase, the headache could be debilitating, but then it follows with fatigue, body aches, and trouble concentrating, dizziness and sensitivity to light. While in this phase the headache is ending, however, people could still be sensitive to smells, tastes and sensory actions.

Weight Loss Surgery Stigma Linked To Lingering Depression Symptoms

weight loss surgery stigma linked to lingering depression symptoms

Things are constantly changing and revolutionising in the health system. Thanks to technologies, there are now new ways to "heal". One such way is by indulging yourself in to the world of virtual reality and gaming, writes Dr Sathyanarayana LD, Consultant neurosurgeon at Narayana Health, Bengaluru for South First. 

He notes that many people undergo surgery to remove brain tumors, which are one of the most complex and could be life-altering conditions for someone to face. Brain tumors could be benign or malignant, however, both affects the person's speech, motor function, memory, and their ability to perform day-to-day activities. This is the reason why, post-surgery, patients may be left with impairments, including physical, cognitive, and emotional. But thanks to technological advancement in the field of health, virtual reality (VR) and gaming have become "powerful tools for neurorehabilitation". 

Dr Sathyanarayana notes that these means are not just for entertainment anymore. Since these means offer a more immersive and interactive experience, they have the potential to enhance the effectiveness of the treatment and also speed up the healing process, post-surgery. 

The doctor notes that recovering from brain surgery is an intricate and lengthy journey. The brain does not return to full function immediately after the procedure; instead, it must gradually rebuild and rewire itself to regain what was lost.

This remarkable ability of the brain to reorganize and adapt, shaped by continuous learning and experience, is called neuroplasticity. It is through neuroplasticity that the brain creates new neural pathways to compensate for damaged areas and restore lost capabilities. In this complex process of rebuilding, gaming and virtual reality (VR) are emerging as powerful allies.

VR places patients in immersive, computer-generated environments that stimulate multiple senses at once—sight, sound, and even body awareness, known as proprioception. These rich sensory experiences actively engage different areas of the brain, sparking changes at the synaptic level, where neurons communicate with each other.

By simultaneously activating motor, sensory, and cognitive regions of the brain, VR encourages synaptic plasticity and broader neural reorganization. This multi-layered engagement fosters a more cohesive and efficient path to recovery, helping the brain rebuild its networks in a meaningful and impactful way.

<h4>Relearning Movement Through Virtual Play</h4>

Post-surgery, many patients face motor impairments like weakness or poor coordination. Virtual reality offers a safe and stimulating space to relearn movement through repetition and task-specific training—key elements for motor recovery.

For instance, VR games that simulate cricket—batting, catching, or goalkeeping—encourage repeated use of the shoulder, arm, and hand, helping restore motor skills. These games also adapt in difficulty and provide real-time feedback, keeping patients motivated while preventing fatigue.

Watching and participating in virtual activities also stimulates mirror neurons—cells involved in motor learning—which may strengthen communication between remaining healthy brain circuits and support recovery.

<h4>Training the Brain to Think Again</h4>

Beyond physical rehabilitation, brain surgery often impacts attention, memory, decision-making, and problem-solving. Gaming and VR can simulate real-life tasks in a structured, repeatable way, challenging cognitive functions in an enjoyable format.

Games involving memory recall, puzzles, and strategic decision-making push the brain to stay active. Over time, this improves working memory, executive function, and mental sharpness—key components of cognitive healing.

<h4>Emotional Healing in a Virtual World</h4>

Recovery is not just physical or cognitive—it’s deeply emotional too. Patients may feel anxious, depressed, or lose confidence. Immersive VR experiences can provide psychological comfort by offering calming spaces or achievement-oriented challenges.

These environments give patients a chance to see their progress, rebuild self-esteem, and stay hopeful—factors that are vital for long-term motivation and adherence to recovery routines.

<h4>Why VR and Gaming Work in Neurorehab</h4>

<strong>Repetition with engagement</strong>: Games make repetitive rehab feel enjoyable, which is essential for promoting neuroplasticity.

<strong>Customized progress: </strong>VR systems offer real-time biofeedback and adaptive difficulty, ensuring that challenges remain effective and engaging without overwhelming the patient.

<strong>Affordable and scalable: </strong>Innovations from institutions like IIIT Hyderabad’s Serious Games Lab are making VR solutions accessible and low-cost, even for rural and public healthcare settings.
