If hand sanitisers kill 99.99% of germs, then who are those 0.01% who survive? There are three major kinds of germs which remain active even when you have used your sanitiser.
Among them, is the norovirus that causes diarrhoea and vomiting outbreaks in places like cruise ships and schools. It is superior to many other viruses because it has a protein capsid, which is resistant to the effects of alcohol.
Norovirus is a group of viruses that causes common illnesses and is also very contagious. It is especially active in the colder month and comes back seasonally. The first norovirus outbreak occurred in Norwalk, Ohio, USA, in a school in 1968, this is where it gets it name from.
The next on the list is enterococcus faecium, and it lives in the gut. As per a 2024 study titled Enterococcus faecium: evolution, adaptation, pathogenesis and emerging therapeutics, published in Nature journal, it is a Gram-positive bacterium that is a core member of the intestinal microbiota of humans and animals and an opportunistic pathogen that causes life-threatening infections, particularly among hospitalized patients. It mutates in a way that it absorbs carbohydrates and forms a gooey, slime-like substance called the biofilm, which makes it resistant to alcohol.
Another one is clostridium difficile. This is responsible for causing horrendous diarrhoea and vomiting in hospitalised patients. It also has a remarkable ability to respond to environmental stressors including alcohol gel by going to sleep. It produces spores and allows all metabolic activity.
Clostridium difficile (C. diff) is a type of bacteria that can cause colitis, a serious inflammation of the colon. Infections from C. diff often start after you've been taking antibiotics. It can sometimes be life-threatening.
Apart from the germs and pathogens, another reason why your label reads that it kills 99.99% is to avoid any legal hassles. If someone uses a specific product and falls sick, then the person cannot sue the company as the company did not give a 100% safety guarantee against the germs.
A better way to be healthy is always to clean your hands with soap and water and wear gloves wherever is possible.

Multiple Sclerosis is a chronic and progressive neurological condition affecting an estimated 1.5–2 lakh people in India, and remains one of the country's most overlooked invisible disabilities.
Many of its symptoms, including fatigue, cognitive impairment, chronic pain, visual disturbances, and bladder dysfunction, are often not outwardly visible, contributing to delayed diagnosis, barriers to disability recognition, insurance challenges, and difficulties in accessing long-term care and support.
In a significant step towards strengthening disability-inclusive healthcare and social protection in India, policymakers, neurologists, disability rights advocates, insurance stakeholders, and persons living with Multiple Sclerosis (MS) today endorsed a landmark 10-point Declaration on Invisible Disabilities and Gender at the National Policy Dialogue organized on the occasion of World Multiple Sclerosis Day 2026.
The National Policy Dialogue was held under the theme, "Shaping Policy. Advancing Access. Improving Lives."
"India has made significant progress in recognizing the rights of persons with disabilities, and conversations such as these are essential to ensuring that our laws, policies, and institutions continue to evolve in ways that better reflect the lived experiences of people affected by conditions such as MS," said Menaka Guruswamy, Member of Parliament, Rajya Sabha.

Experts from the Multiple Sclerosis Society of India (MSSI) stated that for people living with Multiple Sclerosis, the challenges often extend far beyond the disease itself.
Delayed access to insurance, high out-of-pocket costs, limited awareness of available entitlements, and the absence of comprehensive patient data continue to create barriers to timely care.
Thus, they expect the Declaration to catalyze stronger insurance inclusion, better access to support systems, and a more robust national understanding of the true burden of MS in India.
The Declaration on Invisible Disabilities and Gender outlines a roadmap to strengthen implementation of the Rights of Persons with Disabilities (RPwD) Act, 2016, and improve the inclusion of invisible neurological conditions within India's healthcare, disability, and welfare systems.
Key recommendations include:
The declaration reflects a growing consensus among stakeholders that India's healthcare and social protection systems must evolve to better address invisible conditions that significantly affect an individual's functional ability, quality of life, and socioeconomic participation.
"Multiple Sclerosis is a complex, unpredictable, and lifelong neurological condition that requires early diagnosis, timely intervention, and sustained access to advanced therapies. While often simplified for patient understanding, the clinical reality is far more challenging and demands a nuanced approach to treatment and long-term care," said Dr. R.K. Dhamija, Distinguished Neurologist, Director, IHBAS, and Chair, National Task Force, NITI Aayog Brain Health Initiative.
"Investing in neurological care is not merely a healthcare expenditure; it is an economic imperative that helps prevent irreversible disability, reduces long-term care costs, and enables people to remain active and productive," Dr. Dhamija added.

For many people, tobacco does not begin as an addiction; it starts as a habit woven into ordinary moments of daily life. A cigarette shared with friends, a smoke break during a stressful day, or chewing tobacco after meals can soon become a routine that feels difficult to avoid.
While these habits may seem harmless in the beginning, tobacco slowly affects nearly every organ in the body, often giving subtle warning signs long before a serious disease is diagnosed.
These effects rarely manifest suddenly and usually come after years of prolonged use. It is this slow progress that leads most tobacco users to believe that "I am fine." But there are unmistakable signs of some diseases brought about by the use of tobacco that ought not to be dismissed:
Oral cancer caused by tobacco often appears initially in the form of persistent mouth ulcers, white or red patches inside the mouth, and jaw stiffness. These painful and irritating conditions can be so subtle that a person is not concerned by them.
Persistent changes like the change in your voice pitch or constant throat irritation are not to be taken lightly, either; they could be signs of deeper problems arising. Seeking medical help when it is still in the superficial stages will not only decrease your chances of being treated with aggressive measures but may actually result in an easier way to fight the condition.
Tobacco affects much more than just the lungs, and many symptoms associated with chronic conditions often go unnoticed.
The most important remedy at our disposal is not a complicated surgery but an accurate identification of such conditions at their superficial stage, allowing for minimal and non-invasive treatments.
The human body is an incredibly powerful machine at healing, and the instant the consumption of tobacco ceases, a chain of events kicks off that increases circulation and improves lung function.
If you ever find yourself dealing with a persistent cough, mouth ulcer, or undue fatigue, it is advisable to visit a specialist at the earliest to prevent future complications.

A growing body of global research is beginning to point in one direction: our eyes are under strain like never before. As per the report published on PubMed, myopia is projected to rise significantly worldwide, increasing from about 27% of the global population in 2010 to nearly 52% by 2050, highlighting its emergence as a major public health concern.
Although genetics has long contributed, there appears to be a significant environmental factor associated with how fast this shift has occurred.
Screens have become an integrated part of everyday lives, from the time of waking up to work on digital screens or scroll through phones late into the night. Digital devices are no longer optional but a constant priority.
Work, education, and entertainment are all now done on screens with little or no interruption. The growing generation of gadgets has its own advantages, but its impact has significantly contributed to the alarming rise in cases of myopia.
There are three major significant ways prolonged screen time could affect vision:
Mild discomfort, such as dryness, headaches, and blurred vision, can lead to more chronic issues. Digital eye strain is common among adults and children alike. However, the long-term outcome is the main concern.
Progressive myopia increases the chances of developing serious eye diseases like glaucoma, retinal detachment, and macular degeneration, and having to wear stronger prescription glasses. These aren't just short-term inconveniences; they can create lifelong risks that severely affect the quality of life.
The days when children spent their time flying kites, playing marbles, feeling the wind on their faces, and returning home with dust-covered hands have gradually faded into memory. The COVID-19 pandemic accelerated an already existing trend.
The screen time increased as many schools transitioned to online education and remote workers increased due to the pandemic. Above all, children experienced a sudden reduction in outdoor activity with increased exposure to digital devices.
The phase indicated a noticeable drop in the vision of the people. This period has often been referred to as a phase of “quarantine myopia,” where many young individuals reported a noticeable decline in vision.
As individuals return to normalcy, the habits that were established are continuing, and concern is being raised about a generation having poorer visual health.
Consistent habits are needed to address this issue:
The increase in use of screens is not an isolated event; it is part of the larger trend affecting how we live and work. To address this issue, we need to develop awareness among individuals, families, schools, and workplaces about proper screen use. A balanced daily routine, guided by parents, plays a crucial role in maintaining healthy vision in children.
Collective responsibility among teachers, parents, and government authorities is essential to prevent visual complications, as children represent our future generations. Greater public awareness around digital eye strain and eye health is also necessary, as it often serves as a precursor to multiple health complications.
Eye health must be seen as an essential part of overall well-being. The current trend may still be a developing issue, but it requires urgent attention. Acting early, with informed choices and preventive care, can ensure that technological progress does not come at the cost of long-term vision health.
