Winter is here, which means the season of sickness too is here. While viruses and sickness run throughout, winter is when the chilly weather further makes it worse for those prone to sickness. Especially, if they are kids, as their immunity is not fully developed.

Does that mean it is inevitable for kids to be sick?

Anytime a child is exposed to another child, they will fall sick. This is because germs are transferred in the air or by touch, and children, being curious, always touch things, including their own faces, mouths and easily pick up germs and spread them. While prevention is impossible, there are steps that can be taken to reduce this.

Experts and medical professionals recommend to follow the vaccine schedule by the Centers for Disease Control (CDC) and American Academy of Pediatrics (AAP). Vaccines have be proven to protect people, children, and infants from serious and deadly infections.

While sicknesses like a common cold do not have a vaccine, good hygiene can help prevent the spread of germs. Teaching your kids to wash hands after touching toys, or any other surface and other people is a great way to start it.

Exposure to germs at an early age strengthens child's immune system

Is there really any truth in the statement? When we encounter infections, our immune system creates antibodies that either prevent future infections or help the body fight them off more effectively, often leading to milder illness. The "hygiene hypothesis" proposes that living in an overly clean environment might hinder the immune system's development, potentially increasing the risk of allergic conditions like asthma.

Although research has explored this idea, many immunologists (experts in the immune system) have raised concerns and expressed disagreement with the hypothesis.

In reality, most children don’t grow up in sterile environments. They are naturally exposed to a variety of germs, providing ample opportunities for their immune systems to strengthen and adapt.

Sanitizing Child's Toys

It is a good practice to regularly disinfect your children's toys and anything they share with others or take to school.

It is important to know the difference between cleaning, sanitizing, and disinfecting. While cleaning removes visible dirt, sanitizing decreases the number of germs on the surface, whereas disinfecting kills germs.

Also make sure to read the labels correctly and prevent any toxic toys to make its way to your kids, so it cannot be inhaled or ingested.

How to disinfect toys?

You can start by cleaning all the toys that has come in contact with your child's hands and mouth with soap and water. Then, use a sanitizer to clean everyday items, things that remain in your child's environment. Then use disinfectant, especially if your child is sick or if someone sick has touched your child's toys.

If you are wondering which sanitizers to go for, the Environmental Protection Agency (EPA) website has come up with a list of approved sanitizers and disinfectants that are effective.

A rare 19th century disease that was once seen in sailors has claimed the life of a six-year-old boy in Queensland, Australia. A severe vitamin C deficiency, which went undetected for a long time, seems to be the reason behind the child's unfortunate death.

Connor Dean passed in August 2024 at Queensland Children’s Hospital. Newly released findings from Deputy State Coroner, Stephanie Gallagher, concluded that severe vitamin C deficiency, consistent with scurvy, was the most likely factor in his death that happened following cardiac arrest.

The case has drawn attention as scurvy is now considered extremely rare in countries where fresh food is widely available. But it has not disappeared completely.

Most Severe Outcome Of Scurvy

Scurvy develops when the body does not get enough vitamin C, or ascorbic acid, for a prolonged period. Vitamin C is needed to make collagen, a protein that helps maintain blood vessels, skin, bones, cartilage, and other tissues.

When there is a severe deficiency, blood vessels and connective tissues can become fragile, leading to bleeding, inflammation and problems with wound healing.

In Connor's case, his symptoms initially did not indicate scurvy clearly. He developed knee pain, limping and a shuffling gait in July 2024. His symptoms were initially thought to possibly be related to a playground injury. Doctors also considered conditions like infection and leukaemia.

His health deteriorated further. Doctors observed that he developed a persistent rash, reduced blood flow to the brain, renal problems, multi-organ failure and sepsis.

Severe vitamin C deficiency eventually emerged as the condition that could connect many of these symptoms. The coroner found that Connor's death was associated with severe vitamin C deficiency consistent with scurvy.

Why Was The Child Become Deficient In Vitamin C?

According to the coroner, Connor's paediatrician had raised concerns about his growth and nutrition due to his diet. By 2023, he had become a very fussy eater and was avoiding fruits or vegetables completely. His diet was described as containing foods like white bread, beef sausage, custard and chocolate.

His mother had also said that he was taking a multivitamin. However, the supplement he was taking was not the one his doctor had specifically recommended. The coroner also found that the product's label did not include vitamin C.

Does Scurvy Risk Exist Even Today?

Scurvy exists even today even though severe cases are uncommon. A child does not develop scurvy because they refuse to eat fruits and vegetables for a few days. Severe deficiency generally develops after prolonged inadequate vitamin C intake.

Children with highly restricted diets are in high-risk groups, especially when their food choices exclude most sources of vitamin C. The risk can also be greater when there are underlying medical or developmental challenges that affect eating.

Connor had Down syndrome and a congenital heart condition, along with prolonged concerns about his growth and diet.

What Are The Warning Signs Of Scurvy?

Early symptoms are not specific, which can make the condition difficult to recognise. Possible signs include:

• Fatigue and weakness
• Irritability
• Poor appetite
• Leg or joint pain
• Swollen or bleeding gums
• Easy bruising
• Skin changes or small haemorrhages
• Poor wound healing
• Anaemia

As deficiency becomes severe, bleeding, tissue damage and serious complications can develop.

While modern food availability has made severe vitamin C deficiency uncommon, prolonged restrictive eating can still create serious nutritional gaps.

An analysis of health records from more than 1 million births found that the share of newborns whose parents refused the vitamin K shot rose by more than 57% during the first half of 2026. The rate increased from 5.2% to 8.1%, according to Reuters.

Vitamin K is a routine injection given to newborns within hours of birth. The number may sound like a small percentage but doctors are worried as vitamin K deficiency can cause sudden, potentially fatal bleeding in otherwise healthy babies, including bleeding inside the brain.

Why Do Newborns Need Vitamin K?

Newborns, however, are born very little vitamin K. Only small amounts cross the placenta during pregnancy, while the bacteria that help produce the vitamin have not yet become established in a newborn's intestine. Breast milk also contains very small amounts.

This leaves babies temporarily vulnerable to vitamin K deficiency bleeding, or VKDB. The standard vitamin K injection given after birth is meant to prevent that deficiency from becoming serious.

What Happens If A Baby Does Not Get The Shot?

The most concerning part about VKDB is that parents may have no warning that something is wrong with the baby. Bleeding can occur internally, including in the intestines or brain. According to the CDC, around 30% to 60% of late VKDB cases involve bleeding inside the brain.

Late VKDB can occur from one week to six months after birth, often in babies who are born completely healthy. The CDC says newborns who do not receive the vitamin K shot are 81 times more likely to develop severe bleeding than babies who receive it.

Possible symptoms can include unusual sleepiness, irritability, seizures, vomiting, bruising or a bulging soft spot on the baby's head. But importantly, most cases have no warning signs before a life-threatening bleed occurs.

Why Are More US Parents Refusing It?

Reuters' analysis found that refusals accelerated sharply this year. Pediatricians and public-health experts linked the trend to growing mistrust of medical interventions and misinformation, amid other changes in US public-health messaging.

The CDC has historically recommended a vitamin K injection at birth, with the practice dating back decades. Its guidance says the shot is the most reliable way to prevent VKDB.

Doctors Are Concerned About The Current Trend

The concern among pediatricians is that if refusal rates continue climbing, VKDB could stop being a rare neonatal emergency and start appearing more often in hospitals.

For a newborn who looks perfectly healthy, the risk can seem invisible and not so concerning. The problem is that the bleeding the vitamin K shot is meant to prevent can also be invisible until it becomes a medical emergency.

The UK today began the first phase of its flu vaccination program, offering jabs to millions of children and pregnant women ahead of winter.

Nearly 19 million people received their flu jab in England last year, helping prevent an estimated 104,000 hospitalizations.

Why Do Early Flu Vaccinations Matter?

Flu season typically peaks in December and January. Starting vaccinations earlier for children and pregnant women aims to protect those most vulnerable to serious illness and limit the spread of the virus before it circulates more widely.

Starting vaccination in September gives children and pregnant women time to build protection before flu begins circulating more widely. As per the NHS, the children’s flu vaccine can take up to 14 days to work.

Who Gets the Flu Jab First?

Children and pregnant women are among the first groups offered vaccination because they are more vulnerable to serious illness from flu.

Most school-aged children will receive their vaccine, via nasal spray, at school.

Parents of two- and three-year-olds, as well as children in clinical risk groups, will be invited to arrange vaccination through their GP practice.

Pregnant women can receive the flu jab at any stage of pregnancy through their maternity team, GP practice or participating pharmacy.

NHS teams are also taking vaccines into local communities, including through high street pharmacies and mobile vans.

Why Are Young Children and Pregnant Women More Vulnerable?

Flu can be much more serious than a bad cold. Every winter, thousands of children require hospital care because of the virus, while pregnant women also face a higher risk of serious illness.

Flu can spread quickly among younger age groups, which means vaccinating children can also help limit transmission to people who may be more vulnerable, including babies, grandparents and pregnant women.

Vaccinating pregnant women can also help protect their newborn babies in their first weeks.

“Flu can really knock you for six, and for some children and pregnant women it can mean becoming seriously ill or ending up in hospital. Getting vaccinated only takes a few minutes, but it can make a real difference – helping protect you and the people around you from getting seriously unwell,” said Dr Amanda Doyle, National Director for Primary Care and Community Services at NHS England.

When Will Other Groups Get Vaccinated?

From 1 October, flu vaccinations will be offered to other eligible groups, including:

• People aged 65 and over
• Adults with some long-term conditions
• Care home residents
• Carers
• Close contacts of people who are immunocompromised
• People experiencing homelessness
• Frontline health and social care workers

Parents of two- and three-year-olds will also be able to book appointments at participating community pharmacies through the National Booking Service from October.

NHS Expands RSV Vaccination Program

The NHS’s year-round RSV vaccination program is also expanding from today to include people aged 65 to 74 with a weakened immune system or certain long-term lung conditions.

RSV can make babies and adults with long-term lung conditions seriously unwell and increase their risk of hospitalisation.

Eligible people can receive the vaccine through their GP practice or, in some areas, a participating pharmacy. Those eligible should expect an invitation from their GP.

Pregnant women can also receive RSV, whooping cough and flu vaccines to help protect their newborn babies in their first weeks.

“Vaccinations play a vital role in protecting those most at risk from flu and they are also crucial for relieving pressures on our NHS over the winter months,” Secretary of State for Health and Social Care Yvette Cooper said.

“Everyone who is eligible for a free vaccination will be notified through their phone or in the post,” Cooper added.
