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.

Massachusetts is moving to strengthen postpartum mental-health care after the controversial trial of Lindsay Clancy increased focus on gaps in treating serious mental-health conditions during and after pregnancy.

Governor Maura Healey has proposed $2 million to expand voluntary nurse home visits to families with newborns, along with $250,000 to strengthen a state program that helps healthcare providers identify and treat mental-health and substance-abuse problems during pregnancy and after birth.

The state's Department of Public Health will also update regulations governing perinatal mental-health screening to identify a broader range of conditions, including mood and anxiety disorders and postpartum psychosis.

Massachusetts Expands Postpartum Mental Health Screening

The current Massachusetts law already requires postpartum depression or major depressive disorder screening for eligible postnatal individuals receiving care from primary-care providers, obstetricians, midwives and pediatricians.

But mental health problems after pregnancy can extend beyond depression.

The state's updated approach is expected to give healthcare providers more opportunities to ask about a patient's mental health during and after pregnancy, including during visits with an obstetrician, primary-care doctor or pediatrician.

Healey said, “Becoming a mother is a profound life change, and every parent deserves support — not just during pregnancy, but in the months that follow.”

She added, “Postpartum depression, anxiety and other maternal mental health conditions are real medical conditions, and no mother should feel ashamed to ask for help or feel like she has to navigate this journey alone.”

The changes are particularly relevant because there is currently no validated screening tool specifically for postpartum psychosis. Massachusetts health guidance says diagnosis depends on a healthcare provider assessing the person's symptoms.

More About The New Programme

The proposed $2 million investment would expand the state's Welcome Family programme so that all families with newborns can be offered a voluntary nurse home visit.

Massachusetts has around 68,000 births a year, while the programme currently reaches about 3,000 families annually. During a visit, a nurse can assess the health of the mother and baby, answer questions about feeding and sleep, and connect families with additional support.

The state also plans to invest $250,000 in the Massachusetts Child Psychiatry Access Program for Moms, which supports healthcare providers treating maternal mental health and substance-use conditions.

The additional funding could also help track postpartum psychosis data and improve education for healthcare professionals, mothers and families about warning signs.

Early Detection Is Key

Perinatal mental-health conditions can affect people during pregnancy and after childbirth. Depression and anxiety are more common, while postpartum psychosis is rare but requires urgent medical attention.

Massachusetts' move aims to ensure that mental-health concerns are not identified only during a dedicated postpartum visit, but also when new parents interact with other parts of the healthcare system.

The measures follow the trial of Lindsay Clancy, whose attorneys argued that she experienced postpartum psychosis when she killed her three children in 2023. Prosecutors disputed the defence's argument, and the jury ultimately failed to reach a unanimous verdict, resulting in a mistrial.

Healey said the bigger goal is to make conversations about maternal mental health more routine. She said, “To every mom who has struggled with her mental health before, during or after pregnancy, I want you to know we see you — I see you.”

A 54-year-old woman in Greece recently gave birth to a healthy baby girl using an embryo that had been frozen for more than two decades. The case has marked a milestone in IVF, raising an intriguiging question: does a frozen embryo eventually have an expiry date?

Cristina Rapti-Tzelepi and her husband, Constantinos Raptis, welcomed their daughter Georgia in Athens on September 9.

The embryo was originally cryopreserved in March 2004 and was transferred in December 2025. The baby weighed 3.49 kg at birth.

The couple decided to use one of their remaining embryos after their 21-year-old son, Giorgos, died in a road accident in October 2025. Their son had also been born following IVF using an embryo from the same original treatment.

The case is remarkable as the embryo remained frozen for more than two decades. But scientifically, that does not mean the embryo continued ageing for 22 years.

Does A Frozen Embryo Actually Age?

A frozen embryo does not age in the way a an actual human person does. During cryopreservation, embryos are stored at extremely low temperatures, generally around -196°C in liquid nitrogen. At this temperature, biological processes that drive cellular ageing effectively stop.

The key is maintaining stable cryostorage conditions. The American Society for Reproductive Medicine says cryopreserved embryos must be maintained under stringent conditions, with IVF laboratories monitoring liquid-nitrogen levels and storage systems.

So, an embryo frozen in 2004 does not biologically become a 22-year-old embryo. Its chronological storage time increases, but its cells are preserved in the state they were in when frozen.

Long Storage Of Embryo & Healthy Pregnancy

A recent systematic review and meta-analysis published in Human Reproduction Open examined 23 studies involving more than 250,000 embryo-transfer cycles.

Researchers found that embryos stored for longer than five years appeared slightly less likely to survive thawing, with some reductions in pregnancy and live-birth rates.

However, the outcomes stopped worsening after around two years of storage, with no further deterioration as storage continued for much longer periods.

Longer storage was also not associated with increased risks of premature birth, high birth weight, or birth defects.

Earlier research has similarly found no dose-response relationship between the duration of embryo cryostorage and pregnancy outcomes.

Does An Embryo Have An Expiry Date?

Scientifically, there is no established biological expiry date for a properly cryopreserved embryo. The bigger concerns are the quality of the embryo before freezing, the freezing and thawing technique, laboratory conditions, and whether the embryo survives thawing.

There are also factors like biological limits and legal limits that affect IVF. In Greece, women currently have a legal age limit of 54 for completing IVF procedures.

Rapti-Tzelepi had only a limited window in which to obtain approval and undergo treatment. Her case is therefore not proof that every embryo can remain viable indefinitely. But it provides another striking example of how modern cryopreservation can preserve reproductive potential for decades.

Nearly 76,805 children and adolescents in India are estimated to develop cancer each year. At the same time, childhood cancer can be highly treatable when diagnosed early and managed appropriately, with survival exceeding 80% in settings where timely diagnosis and comprehensive treatment are available.

When people think about preventive healthcare for children, the conversation usually centers on vaccinations, good nutrition, physical activity, sleep and regular health check-ups. These are important for a child’s overall health. But prevention also involves something that is often overlooked: recognizing when a child’s health is changing and seeking medical advice at the right time.

Childhood cancer is different from many cancers seen in adults. In most cases, there is no clear lifestyle-related cause that parents could have avoided. A child developing cancer is therefore not usually linked to something the parents did or did not do. This is important because there is no particular diet, exercise routine or supplement that can guarantee protection against childhood cancer.

The Importance of Recognizing a Pattern

For doctors, one of the more practical ways to improve outcomes is to recognize when a seemingly common symptom is not following its usual course. Fever, tiredness, headaches, loss of appetite or body pain are frequent childhood complaints. But when they persist, keep returning or occur alongside other changes, they should not simply be treated repeatedly without evaluation.

• Unexplained weight loss

• Unusual bruising or bleeding

• Persistent bone or abdominal pain

• A growing lump or swelling

• Repeated headaches

• Changes in vision

These are some signs that may require further assessment. These symptoms are not specific to cancer, but their persistence warrants attention.

Why Early Diagnosis Matters

Most childhood cancers do not have a routine screening test for healthy children. Diagnosis therefore often depends on noticing an unusual pattern and investigating it appropriately.

A delay does not necessarily mean that cancer has been missed, but prolonged delays can allow some cancers to progress before treatment begins. For this reason, awareness among parents and healthcare providers, timely evaluation and appropriate referral are important parts of childhood cancer care.

Prevention Is Not Just About Avoiding Cancer

Vaccination still has a place in the broader cancer-prevention conversation. Hepatitis B vaccination helps reduce the risk of liver cancer linked to chronic hepatitis B infection, while HPV vaccination can help prevent HPV-related cancers later in life. However, these vaccines do not prevent most cancers that occur during childhood.

Similarly, nutrition should be viewed in the right context. A balanced diet supports growth and recovery, including during cancer treatment, but there is no specific food or diet that can prevent a cancer.

The Cost of Childhood Cancer

Childhood cancer can place a significant financial and practical burden on families. Treatment costs may be accompanied by expenses related to travel, accommodation, food and time away from work.

At the same time, families today have more avenues of support than before. Government health schemes, public healthcare facilities and non-government organizations can help with treatment costs and other practical needs. The challenge is ensuring that families are aware of these resources and can access them early enough.

Looking Beyond Treatment

Children who survive cancer may need long-term monitoring for possible effects of treatment on growth, development and other aspects of health.

For childhood cancer, therefore, prevention is less about finding a way to eliminate risk and more about reducing what can be changed: delayed diagnosis, interruptions in treatment and avoidable long-term complications..
