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.

Can Running Marathons Or Ultramarathons Raise Colon Cancer Risk? Study Sparks Concern

Updated May 22, 2026 | 10:15 AM IST

SummaryThe study found that the rate of advanced adenomas — noncancerous tumor which are likely to become cancerous — nearly tripled among the marathon runners, compared to the general population, at 4.5 -6 per cent.

Colon cancer, medically known as colorectal cancer, was historically typical for people aged 50 or older. However, in recent years, the cancer that forms in the tissues of the large intestine has been increasing in prevalence in young adults. As many as one in five colorectal cancer patients today falls into this younger age group.

Now, a study published by the American Society of Clinical Oncology shows that marathons, which are one of the most celebrated physical activities, may be increasing the risk of the disease.

What Did The Study Find?

The team at Inova Schar Cancer Institute in Virginia, US, initiated the study after observing multiple “ultramarathoners” present to their cancer center with advanced colorectal cancer.

To probe the link, they recruited 100 runners to undergo colonoscopies — the gold standard for screening and preventing colorectal cancer. The team then looked at runners ages 35 to 50, who had either completed at least five marathons or two ultramarathons (any runs of 50 kilometers or more).

Presenting the findings at the 2025 American Society of Clinical Oncology (ASCO) annual meeting, Dr. Timothy Cannon, an oncologist at the Institute, stated that

  • Nearly 50 per cent of the participants in the study had polyps, which can become cancerous,
  • 15 per cent had advanced adenomas (noncancerous tumor) which are likely to become cancerous.

Almost always, colon cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.

Moreover, the study found that the rate of advanced adenomas nearly tripled among the marathon runners, compared to the general population, at 4.5 -6 per cent.

How Does Ultra-running Spike Chance Of Developing Colon Cancer?

In general, running and other forms of exercise are known to reduce the risk of developing colon and other cancers. At the same time, exercise-induced gastrointestinal injury is also believed to be associated with reduced blood flow to the intestines during long-distance running.

Notably, to date there is no evidence that definitively shows running causes polyps.

The new study presents a correlation — an increasing relationship between long-distance running and advanced adenomas. It does not prove that running directly causes the adenomas.

The new results suggest that “intensive long-distance running is a risk factor for advanced adenomas of the colon", said Dr. Timothy, in the paper. The team also called for "refining screening strategies" for marathon runners.

It is because runners put their bodies through a lot, which can raise the risk of chronic inflammation, enabling cancerous cells to grow.

Their high-caloric foods for immediate energy can slow down digestion and impact your overall colon health.

What is Colorectal Cancer

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.

It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.

According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened, as the symptoms appear late, impacting treatment outcomes.

The common red flags for colorectal cancer include:

  • rectal bleeding,
  • persistent abdominal discomfort,
  • pain,
  • a noticeable change in bowel habits.

Bruce Willis Has Become More ‘Tender’ Amid Dementia Battle, Says Daughter

Updated May 21, 2026 | 07:00 PM IST

SummaryBruce Willis' diagnosis was confirmed as frontotemporal dementia (FTD) in 2023. It is his third year living with a degenerative disease that slowly chips away at motor skills, communication skills, etc.

From being a macho dude, Bruce Willis’ personality has changed to becoming more ‘tender’ even as the 71-year-old action hero continues to battle dementia, according to his daughter Rumer.

“I’m so grateful I get to go see him,” Rumer, 37, said during a podcast interview. “Even though it’s different now, I’m so grateful.”

“There’s a sweetness. He’s always been this kind of macho dude, and there’s like a — fragile is not the right word, but — just a tenderness that maybe being Bruce Willis might not have allowed him in a certain way,” she added.

Bruce Willis is continuing into his third year living with the condition.

In March 2022, Bruce Willis, the media legend who dominated Hollywood in his prime, was diagnosed with dementia, and since then, his family has been sharing their struggle with his diagnosis and how slowly it has been taking a toll on his health.

The following year, his diagnosis was confirmed as frontotemporal dementia (FTD), which is a degenerative disease that slowly chips away at your motor skills, communication skills, etc. His wife, Emma Heming Willis, noted early signs were subtle changes in his speech, initially mistaken for a resurgence of his childhood stutter.

Rumer is the eldest daughter of Bruce and The Substance star Demi Moore, who were married from 1987 to 2000. The former couple also had Scout Willis, 34, and Tallulah, 32, together.

Although FTD is considered to be one of the rarest forms of dementia, Rumer said the disease is more “prevalent” than she realized.

“It’s wild to me. So many people come up to me now, and they say, ‘My uncle had FTD. My dad had this,” she said.

Earlier this year, in March, a hoax news of Bruce Willis’ death circulated. However, his representatives confirmed that the news is fabricated and that the actor is alive.

"He joins the long list of celebrities who have been victimized by this hoax. He's still alive and well. Stop believing what you see on the Internet," his official representative stated.

What Is Frontotemporal Dementia?

Frontotemporal dementia is a less prevalent type of dementia that mainly occurs in the frontal and temporal lobes of the brain. It tends to affect behavior, personality, language, and movement more than memory, particularly in its initial stages.

In contrast to Alzheimer's, which generally strikes older individuals, FTD can hit at an earlier age—sometimes as young as 40. The symptoms can range from changes in personality, emotional flatness, or the inability to show empathy to impulsiveness, so it is especially hard for spouses and children to cope.

The Mayo Clinic states that the symptoms of FTD vary depending on the most affected part of the brain. The progression is gradual but relentless.

Behavioral symptoms:

  • Socially inappropriate behavior.
  • Loss of empathy and sensitivity to others.
  • Poor judgment and impulsivity.
  • Apathy that can be mistaken for depression.
  • Compulsive habits such as tapping, clapping, or repetitive lip-smacking.
  • Decline in hygiene.
  • Odd eating habits – from sudden sugar cravings to chewing on non-food items.
Language-related symptoms:

  • Trouble understanding and producing speech.
  • Difficulty finding the right words.
  • Using vague terms like “it” instead of specific words.
  • Simplified, telegraphic speech.
  • Errors in building sentences.
Movement-related symptoms (less common but significant):

  • Tremors, stiffness, or muscle spasms.
  • Difficulty swallowing or weakness.
  • Poor balance leading to falls.
  • Inappropriate emotional outbursts, such as laughing or crying.
  • The “wide-based gait” noted by Dr. Gartner falls into this movement-related cluster, aligning with the suspicion of FTD.

Even as injectable aesthetic procedures are gaining popularity as "cosmetic" treatments in beauty clinics and wellness centers across the country, the Central Drugs Standard Control Organisation (CDSCO) has tightened rules around cosmetic use.

In a new public notice issued this week, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.

"Cosmetic means any article intended to be rubbed, poured, sprinkled or sprayed on, or introduced into, or otherwise applied to, the human body," the notice said.

It added that cosmetics are for "cleansing, beautifying, promoting attractiveness, or altering the appearance."

Thus, "products supplied in the form of injectable preparation do not fall under the definition of cosmetics. No cosmetic is permitted to be used as injection by consumer/professionals/aesthetic clinics," the notice added.

What Can No Longer Be Done

The new rules bar professionals and stakeholders from using or manufacturing any cosmetic product intended for injection or medical purposes.

The move also seeks to curb misleading advertising and unauthorised cosmetic practices by clinics and individuals.

The regulator also warned against misleading claims and the use of prohibited ingredients in cosmetic products, saying such violations attract action under the Drugs and Cosmetics Act and Cosmetics Rules, 2020.

"Use of prohibited ingredients in cosmetic products, misleading claims on label, use of cosmetics for treatment, and application of cosmetics through injection attracts violations of the said Act & Rules," the notice said.

The regulator stated that no person shall alter, obliterate, or deface any inscription made by the manufacturer on the container or label of the product intended for use as a cosmetic.

The notice added that the list of generally not recognised as safe (GNRAS) and restricted ingredients is published by the Bureau of Indian Standards (BIS).

It has also encouraged the public and users to report any instance of misleading claims or violations through email and state licensing authorities.

Why Injectable Beauty Clinic Therapies Are Under Scanner

The move follows several incidents of sub-standard cosmetic products found to be sold in the market, ranging from Botox parties in upscale salons to glutathione “skin whitening” drips offered in local aesthetic clinics.

Social media trends, celebrity endorsements, and growing demand for “preventive anti-ageing” treatments among younger consumers have driven the market for injectable beauty products, especially Glutathione drips, as well as detoxifying therapies, in the country.

Medical experts have also been raising concerns over their long-term safety and efficacy. As per experts, unregulated injectable procedures carry risks ranging from allergic reactions and infections to liver and kidney complications in extreme cases.

The new norms, thus, are part of the government's plans to strengthen the regulatory mechanism for cosmetics.

The government is also reportedly planning to designate a Central Cosmetics Laboratory to test cosmetic samples and may also designate any laboratory under its control for testing, according to Mint.

In addition, manufacturers will have to keep details and records of each batch and raw materials. Records are to be maintained for three years after the expiry of each batch. Imported cosmetic products shall bear a code number as approved by the State Licensing Authority.
