While most people have been affected by Covid-19 infections, some have naturally resisted the infectious disease, despite clearly being exposed to the virus.
According to researchers at the University College London, understanding this mechanism of resistance can lead to the development of universal vaccines against the debilitating virus, the BBC reported.
In the study published in the journal Nature, the team closely monitored hospital staff during the first wave of the pandemic -- including by taking regular blood samples.
The results showed one-in-10 had signs of being exposed, but never had symptoms, never tested positive, and never developed Covid-fighting antibodies in their blood.
This Covid-immunity likely came from the body learning how to fight viruses. Part of their immune system was able to get on top of the virus before it managed to take hold -- what's known as an "abortive infection", the team said.
Blood samples showed these people already had (as in before the pandemic) protective T-cells, which recognise and kill cells infected with Covid.
Their immune systems were already "poised" to fight the new disease, Dr Leo Swadling, one of the researchers was quoted as saying.
These T-cells were able to spot a different part of the virus than the bit most of the current vaccines train the immune system to find, the report said.
Vaccines are largely aimed at the spike protein, which covers the outer surface of the Covid virus. However, these rare T-cells were able to look inside the virus and find the proteins that are necessary for it to replicate.
"The healthcare workers that were able to control the virus before it was detectable were more likely to have these T-cells that recognise the internal machinery before the start of the pandemic," Swadling said.
These internal proteins are very similar in all related species of coronavirus, including the ones that are widespread and cause common cold symptoms. It means targeting these proteins with a vaccine could give some protection against all coronaviruses and new Covid variants.

People breathe in up to 7,000 microplastic particles every day from clothes, toys and furnishings, revealed a research.
The total is 100 times higher than expected posing a potential health threat that could rank alongside asbestos or tobacco, the Daily Mail reported.
The study led by Portsmouth Hospitals Trust in the UK, used highly sensitive equipment to count tiny particles less than 10 microns in size just a tenth of the width of a human hair.
Bedding, carpet and soft toys made from synthetic materials, as well as polyester and nylon could be major contributors, they found.
Microplastics were dangerous because they did not break down, Professor Anoop Chauhan, a respiratory specialist with Portsmouth Hospitals Trust, was quoted as saying.
"Having these particles in your body can cause stress and changes in metabolism, it can affect immunity, the ability to fight infections, it can affect your reproductive capacity and potentially it could be carcinogenic causing cancer," Chauhan said.
The study was carried out at the home of a British reporter in Beckenham, south-east London. Up to 28 plastic particles were found every minute in children's bedroom compared with two a minute in the kitchen, the report said.
The team found that when children play with soft toys, the family is likely to each breathe in between 2,000 and 7,000 microplastics a day.
"Things in an occupational setting asbestos, coal or cigarette smoke or anything you inhale has dangers and microplastics are a hidden danger in people's homes," Chauhan said.
"And this is the first study that highlights the level of these that we breathe in everyday life."
He said microplastics did not degrade in the body leaving them to potentially cause inflammation and stress to cells.
"To date, the bulk of research has centred around pollutants outside of the home such as car emissions, but as this initiative proves, it's essential we widen our focus on the dangers in our homes," Chauhan added.
Very small microplastics that are less than 10 microns in size, such as those measured in the new study, can float in the air making them harder to count.

Although the world is recovering from coronavirus pandemic, we must not lower our guards and stay alert when it comes to hand hygiene to curb the spread of the deadly virus. But are we paying sufficient attention to our nail hygiene? Our nails are the index of well-being for our entire body. The manifestations of several critical diseases were first detected within the dirty nails.
The ignorance towards our nails becomes the breeding ground of harmful bacteria. These germs enter our body through our hands because in India we eat through our bare hands. Therefore, nail hygiene is crucial and without it hand hygiene is incomplete.
Practising good nail hygiene involves following a systematic process to ensure the longevity of our nail health. It includes ensuring that food particles, dirt and dust are not sticking to our nails and there is no build-up of nail bacteria. Thankfully, contrary to popular belief, it is not that difficult to maintain good nail hygiene. A little diligence, awareness and attention are sufficient to keep our nails healthy.
Avoiding Nail Hygiene Makes You Prone to Viral Infections
Due to constant negligence towards the cleanliness of the nails, many serious issues like bacterial and viral infections arise. Often these lead to serious health problems. Our hand hygiene is not perfect till the time we clean the undersides of our nails besides washing hands regularly. Most people don't mind sharing nail clippers with others. This is however an extremely unhygienic practice. When we don't share any of our personal hygiene products then why do we share our nail clippers? Nails harbour abundant germs, bacteria and viruses and sharing nail clippers is equivalent to exchanging those microorganisms.
Keep Fingernails Dry and Clean
It prevents bacterial and fungal infections from growing under our nails. It has been observed that prolonged exposure to water can break nails. It is always recommended to wear cotton-lined rubber gloves when washing dishes, cleaning or using harsh chemicals. In order to follow good nail hygiene, we have to be careful about our nail care products. Use a sharp stainless-steel nail clipper with a grime remover, that can remove the hidden germs and grime below the nails. Trim nails straight, then round the tips into a gentle curve. Always wash hands and under nails with soap and water after a nail clipping session.
Keep hands and nails moisturized to avoid the cuticles from overgrowing. Frequent use of nail paint remover, hand sanitisers and harsh soaps can result in the dryness of cuticles along with nails. Keep nails short, trim them regularly and wash hands for at least 20 seconds and then moisturize them, This will make the chance of diseases slimmer and can prevent any kind of viruses. KAI India nail clipper comes with unique features like 100 per cent stainless steel, nail filer, grime remover, nail tray and non-chromium coating making them safe and most effective for maintaining proper nail hygiene.
Here are some of the more ways through which we can keep our nail hygiene intact, thereby protecting it from the damage to nails:
Stay Away From Chewing Fingernails
It has the potential of damaging the nail bed as a minor cut can cause infection. Moreover, when we bite our nails, germs enter our mouths directly.
Be Gentle Towards Hangnails
Never pull off your hangnails. Rather, be gentle towards them and carefully clip them off. Stop using those products which are harsh on nails. Always go for acetone-free products.
Go for A Regular Nail Checkup
If you have a persistent nail problem, consult a doctor or dermatologist for an evaluation.
Do Not Share
Try not to share your nail clipper, as they contain germs. Wash the nail clipper with lukewarm water and wipe with a soft cloth. (Rajesh U. Pandya is the Managing Director of Kai India)

Navratri is the festival where nine days of fasting can be observed by a devotee. Many pregnant ladies wish to fast for their religious or personal beliefs. Though it is said that women during pregnancy should be very careful when it comes to fasting because it is not only the mother who needs all the essential nutrients but also the need of the fetus for healthy growth and development.
However, fasting during pregnancy is not as hard as it allows the consumption of various healthy foods at appropriate intervals. But one thing should be remembered by all pregnant ladies that they should not go hungry for long intervals as a baby's nutrition depends on the mother. It is very important to take carbs during pregnancy while fasting. Carbohydrates play a vital role in our growth system. It is an important nutrient source that not only provides energy to muscles and the brain but using the right kind of carbs in the diet can effectively help to provide essential nutrients, build the desired body or accelerate fitness goals.
There are two types of carbs slow and fast carbs which depends on the Glycemic Index ( the rate at which carbs get digested as compared to glucose secretion).
Fast carbs have a high GI and release energy at a much higher pace and get used quickly which makes you feel hungry often and add to weight gain issues. Fast carbs include processed foods such as bread, sugars, starchy vegetables, fruit juices etc.
As compared to this, slow carbs have a low GI and release energy slowly into the body and help to maintain a "satisfied" feeling as your blood sugar levels are maintained.
There are many non-pregnant women who want to shed extra calories. Fasting will be the perfect time to start their fitness journey. To lose weight and stay healthy, the purpose should be to source the right kind of carbs, which release energy slowly and helps you in the long run. Hence, for that, focus on including slow carbs in your diet such as whole grains, seeds and nuts, beans and legumes, vegetables etc. It also tends to be high in fibre.
Should Carbs Be Taken During Fasting?
Although fasting is a very traditional and customary ritual and most people fast for spiritual purification, there is no denying that if you keep yourself nutritionally in check, it can be therapeutic for the body as it can act as a form of detox and keep you healthy as well. So, it is significant to choose the right food while you are on a fast diet to prevent yourself from being deficient in important nutrients as it can make you likely to develop health ailments like weakness, heart problems, skin issues, defective bone growth, etc.
Pregnant women with illnesses such as diabetes, anaemia, high blood pressure should avoid fasting as it could lead to various other complications.
Avoiding carbohydrates will be the last thing you need to do during fasting as it provides energy to the brain and muscles and make you energetic and more productive throughout the day. So, Make sure you are getting enough right kind of carbohydrates, proteins, minerals and vitamins from different sources and be vigilant about selecting healthy foods rather than munch on processed foods.
There are various food options that include slow carbs and few tips to make your fasting healthier:
Because you are fasting, you tend to eat lesser food than usual, and are hungry at odd times, eating slow carbs foods can help you keep fuller for longer as they take longer to digest and break down. Combine high carbohydrates like potatoes and sabudana (widely used in fasting) with other fibrous vegetables like spinach, cabbage, tomatoes, capsicum, bottle guard, etc. Also, try to bake, roast or grill vegetables instead of deep-frying them. Kuttu is a brilliant combination of carbohydrates (70-75 per cent) and protein (20-25 per cent). It is also rich in proteins, B-complex vitamins and minerals like phosphorus, magnesium, iron, zinc, copper and manganese. Use it to make chapatti instead of gorging on puris.
Samak rice is extremely easy to digest and provides energy, contains a high amount of fibre, B-complex vitamins and important minerals like iron and magnesium.
Try and adopt healthy snacking and don't binge on puris, sabudana vada, potato chips, and other delicacies as they are loaded with sugar, salt and fat content, Instead, opt for roasted makhana as they loaded with antioxidants or a mixture of nuts (almonds/raisins/walnut)/ baked chips, roasted peanuts, etc.)
Eat plenty of seasonal fruits and vegetables.
Eat small meals and do not starve yourself. This will help maintain blood glucose levels and prevent you from feeling low.
Keep yourself hydrated. Drink lots of water and fluids like coconut water, lemon water, and buttermilk without adding sugar. These beverages will keep you satisfied for a long time.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimetre of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs.
Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.
Refrain from Harsh Soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.
Clip Your Nails Regularly: Make use of your personal nail clipper to cut your nails. After cutting your nails at a comfortable length also file them using a nail filer. Never share your nail care clipper as the germs can get transferred to your loved ones. Also, don't forget to use grime remover to remove hidden germs in corners and beneath nails. Also, you may like to file your nails to have a smooth finish.
Good Quality Nail Clipper: Do not use a rusted or chromium coated nail clipper as it might be harmful to skin and might cause dangerous bacterial infections.
Stop The Habit of Nail Chewing: Sometimes anxiety or extreme boredom can lead to chewing of nails. This habit only makes your nails uneven and ugly. Sometimes, our unclean nail folds give rise to viral, bacterial or fungal infections, which in turn can make us sick if we chew our nails.
Exfoliate Your Hands: Similar to the way you exfoliate your face your hands also need it. It helps to keep the dry skin at bay and keep your hands soft. You can buy a scrub or make one at home using brown sugar and olive oil. After scrubbing, you need to massage your hands with moisturizer.
Don't Use Your Nails As Tools: Always keep in mind that your nails are like jewels. Never use them to pry things open such as pop cans, removing keys from the ring, opening letters or scraping off labels. This results in unnecessary breakage of nails, making your hands look dirty.
Be Aware of Nail or Cuticle Inflammation or Redness: If there are any signs of infection, disinfect the skin as soon as possible with an anti-bacterial or anti-fungal ointment.

Sleeping is our body's natural way of balancing the stress level and rectifying any errors in its system. Fix a sleeping time and don't change it no matter what. This is one of the most important changes you must incorporate. The other being hydration water is extremely important for your system. Not only does it help in passing the nutrients throughout your system, but it also helps the body detox and shed the pesky water retention habit. You'll be surprised by the number of times your body confuses thirst for hunger, so always drink adequate water. Set a reminder through a phone app, it can be helpful.
