Overview

This is a disease that is transmitted from mosquitoes to humans and affects many people in the world. Found in densely populated countries and continents, like Africa, Asia and the tropics of the Americas, this has severe symptoms. This viral disease is caused by the Chikungunya virus of the Togaviridae. First identified in the United Republic of Tanzania in 1952 and subsequently in other countries like Africa and Asia. Since 2004 the outbreak of CHIKV virus has become more widespread and caused partly due to the viral adaptations allowing the virus to be spread more easily by Aedes albopictus mosquitoes. The transmission has been noted to persist in countries where there is a large population, but interestingly, the transmission has been interrupted on islands where a high proportion of the population is infected and then immune.

Symptoms

The onset of the disease is usually in 4-8 days and after a bite of an infected mosquitoes, it is characterized by an abrupt onset of fever and then joint pain. This joint pain is severed and lasts for a few days but may prolong for months maybe even years. Other signs are joint swelling, muscle pains, headache, nausea, fatigue and rash. These symptoms also overlap with those of dengue and Zika virus and can be misdiagnosed. Most people fully recover from the infection and experience only mild and sometimes the infection even goes unrecognized. However, there have been cases of eye, heart, and neurological complications. The elderly and newborns are more susceptible to the infection and if they have any underlying conditions then they are likely to become severely ill increasing the risk of death.

Diagnosis and treatment

The diagnosis and treatment of the virus may be done by blood sampling and other tests like reverse transcriptase–polymerase chain reaction (RT–PCR). Other tests detect the activity of the antibodies. These can be detected in the first week after illness onset and can be detected for about 2 months. Many clinical measures can be taken to address fever and joint pain. But there is no specific anti-viral drug treatment for the virus.

Preventing Chikungunya

As this disease is caused by the bite of a mosquito, you must reduce the opportunities to let the mosquito breed. Mosquitoes bite during the day and night, and for people who live in risk areas like southeast Asia, Africa and tropical regions of America, many outbreaks happen each year. The best way to prevent it is to protect yourself from the mosquito's bite. You also must get vaccinated before travelling to any of these regions. Use insect repellent, and wear long-sleeved shirts and pants. You can also treat your clothes and gear with permethrin. As we all know, they tend to breed in humid places and places where they have access to water, so try to close the rooms that are air-conditioned with screens and windows. Use nets and mosquito repellents if you are sleeping outside. There are many different types of mosquito repellents like paper, liquid etc, and they are quite effective. If your job needs, you to be stationary for long hours or frequently go outside you must take the necessary precautions.

World AIDS Day is marked across the globe every year on 1 December to draw attention to HIV and AIDS. In India, the day is observed through awareness drives and community-level programmes held nationwide. The National AIDS Control Organization (NACO), which functions under the Ministry of Health and Family Welfare, leads these efforts and brings people together to support the ongoing battle against the illness.

This year, the government reported a strong decline in HIV cases, noting 49 per cent fewer new infections since 2010, an 81 per cent fall in deaths linked to AIDS, and a 75 per cent drop in mother-to-child transmission between 2010 and 2024.

The update, shared on Sunday for World AIDS Day 2025, also underlines how myths continue to harm people living with HIV. Misconceptions remain widespread, including the belief that the virus spreads through simple physical contact.

What is HIV/AIDS?

The Human Immunodeficiency Virus (HIV) harms the body by attacking helper T-cells, which are vital for immunity. Acquired Immunodeficiency Syndrome (AIDS) develops when these cells fall to very low levels, leaving the body exposed to infections and diseases, as described by the Mayo Clinic.

Common HIV Myths That You Should Know About

• It is a myth that HIV spreads through coughing, touching or shaking hands. Routine contact or a cough does not transmit the virus. Transmission can occur only when the skin has open sores or breaks that allow the virus to enter.
• It is a myth that a person diagnosed with HIV will survive only a short time. With proper treatment that keeps the virus suppressed, people with HIV can live for many years.
• It is a myth that every child born to an HIV-positive mother will also have HIV. With antiretroviral therapy, a planned C-section and other precautions, the chance of passing the virus to the baby can be reduced to below 2 per cent.
• It is a myth that HIV, being a viral infection, cannot be linked to the use of antibacterial or antifungal medicines. Since HIV weakens immunity, those living with it may be prone to common bacterial and fungal infections and may need such medicines for long periods.
• It is a myth that there is no risk when two or more HIV-positive partners are intimate. Unprotected sex can still allow tougher or drug-resistant strains of the virus to evolve and spread.
• It is a myth that people who do not show symptoms cannot have HIV. It can take years for signs to appear, and the only way to confirm the infection is through testing.
• It is a myth that taking medicines before intercourse can fully prevent HIV. Pre-exposure prophylaxis lowers the risk but does not remove it entirely.

World AIDS Day, observed each year on December 1, is a time to pause, acknowledge and renew our commitment. It pays respect to those who lost their lives to AIDS-related illnesses, offers support to people living with HIV and reminds the world that prevention, treatment and rights-based care remain essential. The theme for 2025, “Overcoming disruption, transforming the AIDS response”, urges countries to build stronger systems, widen access to services and uphold the dignity of all communities affected by HIV.

Ludwig Minelli, 92, died on Saturday just days before his 93rd birthday, which would have been on December 5. He was the founder of Swiss right-to-die organization Dignitas. He has died by assisted suicide.

The members of organization paid tribute to him and said that he had always led a "life for freedom of choice, self-determination, and human rights".

Right-To-Die By Minelli

Minelli founded Dignitas in 1998, which has helped many people to choose how they wish to die with dignity. He however began his career as a journalist and worked as a correspondent for the German news magazine Der Spiegel. He then studied law and that is when his interest in human rights took off.

Throughout his life, he campaigned for the right to die and gave Dignitas the slogan: "dignity in life, dignity in death".

"I am persuaded that we have to struggle in order to implement the last human right in our societies. And the last human right is the right to make a decision on one's own end, and the possibility to have this end without risk and without pain," he said in a 2010 BBC interview.

He founded Dignitas after he split from an older Swiss assisted dying organization, Exit, because he said the rules felt too restrictive.

The reason for Dignitas to become famous was because the way it operated. Dignitas offered assisted suicide to non-Swiss citizens who travel to Switzerland because assisted dying is not permitted in their own countries. In a 2008 interview to Der Tagesspiegel, he said that Dignitas assisted 840 people to die, and 60% of them were Germans.

His Life Amid Criticism And Legal Battles

While he devoted his life for a cause, he was not spared from criticism. He was often criticized for an alleged lack of transparency over the financial dealings of the organization. He was further criticized for offering assisted dying options to those who were not terminally ill, but wanted to end their lives. He also faced numerous legal battles, and many of which were also appealed to Swiss apex court.

The Wins He Made

As per Dignitas, his work had a lasting influence. In 2011, the European Court of Human Rights announced the right of a person capable of judgment to decide on the manner and the time of their own end of life.

While in his own country, assisted dying was permitted under Swiss law since 1942, under strict condition, of course, Euthanasia still remains illegal there.

The main difference is that in Switzerland, a physician cannot administer a lethal injection, which is what euthanasia is. However, a physician can provide the means for a person to end their own life, and the individual must perform the final act themselves.

The legality of assisted suicide is based on Article 115 of the Swiss Criminal Code from 1942, which prohibits assistance only if motivated by selfish reason. The conditions for assisted suicide includes that the assistance must not be for selfish motives and must be provided to someone of sound mind who has made a self-determined and enduring decision to die. The person must also be suffering from an unbearable and uncontrollable condition.

The shape of your gluteus maximus, the largest muscle in your backside, may offer surprising clues about your likelihood of developing diabetes. New research suggests that the contours of this major muscle change with age and health conditions, helping scientists better understand how fitness, muscle health, and metabolism are connected.

Ageing, Weight, and Diabetes: What We Already Know

For years, the NHS has warned that ageing and excess weight increase the risk of developing Type 2 diabetes. However, this new study goes beyond traditional measures, proposing that the shape of the gluteus maximus itself shifts as people age or develop conditions such as osteoporosis or diabetes. These subtle muscular changes could provide valuable information about a person’s metabolic health.

Why the Gluteus Maximus Matters

Researchers from the University of Westminster highlighted that the gluteus maximus plays a key role not just in movement but also in metabolic regulation. Healthy, well-maintained muscles can improve blood sugar control and reduce the burden on organs involved in glucose processing.

Dr Marjola Thanaj, co-author of the study from the university’s Research Centre for Optimal Health, explained, as reported by Independent: “People with higher fitness, as measured by vigorous physical activity and hand grip strength, had a greater gluteus maximus shape, while ageing, frailty and long sitting times were linked to muscle thinning.”

Mapping the Muscle

To understand these differences, researchers used advanced MRI 3D mapping to create a detailed anatomical model of the gluteus maximus. By analyzing more than 61,000 MRI scans from the UK Biobank database, they discovered that the shape, not the size, of the muscle varied significantly between individuals with diabetes and those without it.

What the Study Found

The MRI analysis revealed distinct, sex-specific patterns linked to Type 2 diabetes. Among male participants living with the disease, those classified as “frail” showed widespread muscle shrinkage across the gluteus maximus, indicating a loss of muscle quality and strength.

Women with diabetes, on the other hand, had enlarged muscle shapes — not because of increased muscle strength, but because of fat infiltrating the muscle tissue. This type of fat infiltration often signals declining muscle function and poorer metabolic health.

Dr Thanaj said these patterns underline a crucial point: men and women can experience the same illness in very different biological ways, which may influence diagnosis and treatment strategies in the future.

Why Maintaining Muscle Mass Matters

Beyond appearance or strength, muscle health is essential for long-term wellbeing. Maintaining muscle mass supports blood sugar regulation, reduces the risk of cardiovascular disease, and lowers the likelihood of developing fatty liver disease, all conditions closely linked to metabolic health.

Professor Louise Thomas, senior author of the study, told The Times: “Maintaining muscle mass as we age is one of the most important things we can do for our long-term health. If people understand how important their muscles are, and make small changes to keep them healthy, that could have a huge impact on disease across the population.”

Small Steps to Strengthen Your Glutes

Improving glute muscle health doesn’t require intense gym sessions. Simple actions such as taking the stairs instead of the lift, adding squats or lunges to your routine, or breaking up long periods of sitting can help tone and strengthen the gluteus maximus.
