Kids love going around places, playing, and exploring new things. While all of this is fun, it can expose them to diseases. When they come from school, they are exposed to various germs through air and transmission or direct contact. They also touch surfaces a lot, then their face, then their mouths. This makes it easy for illness to spread. While it is impossible to prevent illness completely, there could be several measures that can reduce the risk and support recovery.
Vaccination is a critical step in preventing severe illnesses. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) recommend following an established vaccine schedule. Vaccines protect against life-threatening infections, including those that disproportionately affect infants and young children.
While no vaccine can prevent one from common cold, good hygiene practices can significantly reduce germ transmission. Parents must therefore encourage their children to wash their hands after touching toys, hard surfaces, and other people. What is more important is proper hand hygiene, as handwashing with soap and water is the most effective way to eliminate germs.

There are several research that suggests that early exposure to germs may help develop a child’s immune system, a concept known as the "hygiene hypothesis." However, many immunologists argue against this theory, noting that children naturally encounter enough germs to build immunity without unnecessary exposure to unsanitary conditions. A balanced approach ensures children develop a strong immune response without increased risk of illness.
Regular cleaning of toys, school supplies, and frequently touched objects is essential. Understanding the difference between cleaning, sanitizing, and disinfecting can help:
It is important to read product labels carefully, use child-safe cleaning products, and rinse toys thoroughly after disinfection, especially those that go into a child’s mouth.
To minimize germ exposure, parents should clean objects with soap and water first and then use a sanitizer for everyday items. Disinfectants, which are stronger, should be used on objects that a sick person has touched. The Environmental Protection Agency (EPA) provides a list of approved sanitizers and disinfectants that effectively kill germs.
Teaching children proper hygiene without creating fear is essential. Make handwashing engaging by incorporating songs or counting games. Explaining the benefits of hygiene in a positive way helps children understand that washing hands protects them and others. Parents can reinforce these habits by leading by example.
A strong immune system helps children fight infections more effectively. Proper nutrition plays a crucial role in immune support. A balanced diet should include:
Multivitamins are generally unnecessary for well-nourished children, but if supplements are used, they should be free of added sugars and taken under supervision to prevent choking hazards.
Proper respiratory hygiene reduces the spread of illness. Parents should model behaviors such as covering their mouths with an elbow when coughing or sneezing. Using tissues and disposing of them immediately is also a good practice. Reinforcing these habits through positive encouragement makes children more likely to adopt them.

Musculoskeletal problems such as back pain, once more commonly associated with adulthood and old age, are increasingly being reported among schoolchildren, experts at the Indian Association of Physiotherapists (IAP) have warned.
Ahead of the World Physiotherapy Asia Western Pacific (WPAWP) Regional Conference 2026, IAP experts flagged a reported 40% rise in musculoskeletal problems among schoolchildren, citing sedentary lifestyles and poor movement habits as key concerns.
The experts called for greater focus on prevention, movement education and physical fitness from an early age.
“Back pain does not start in old age. We are seeing a concerning 40% rise in musculoskeletal problems among schoolchildren, and this should make us rethink how we approach preventive healthcare in schools,” Prof. Dr. Sanjiv K. Jha, President of the Indian Association of Physiotherapists (IAP), said.
He flagged concerns that long hours of studying and prolonged screen use are making children increasingly physically inactive. Reduced movement, along with inadequate strength, flexibility and fitness, may contribute to musculoskeletal problems and could have long-term consequences if not addressed.
“We need to shift from treating musculoskeletal problems after they appear to preventing them through early education, fitness and appropriate physiotherapy interventions,” Dr. Jha said.

Indian research indicates that musculoskeletal symptoms are a significant concern among school-going children.
A study of 934 children aged 8–15 years from four schools in Bhopal found that 55.9% reported pain during the previous 12 months, while 41.6% reported pain during the preceding 10 days and 21.3% had visited a doctor for the problem. The study also found that the average schoolbag weighed 16.5% of the students’ body weight.
Another study among schoolchildren aged 10–16 years in urban and rural areas of Khurda district, Odisha, found an 18.8% prevalence of musculoskeletal pain during the preceding year. The research examined factors including backpack weight, age, gender and body measurements.

Experts caution against attributing childhood back pain solely to heavy schoolbags. Scientific evidence suggests that musculoskeletal pain can have multiple contributing factors, including physical activity, movement habits, previous injuries, psychosocial factors, prolonged sitting and individual characteristics.
This points to the need for a broader approach to childhood musculoskeletal health rather than focusing exclusively on schoolbag weight.
“We should not totally link childhood back pain to a heavy-school-bag problem. Children need regular movement, physical fitness, strength, flexibility, good movement habits and awareness about how they use their bodies,” Dr. Ruchi Varshney, part of the IAP, said.
She added that physiotherapy can help schools introduce preventive programs focused on movement education, early identification of problems and healthy physical activity rather than waiting until pain becomes persistent.
Physiotherapists believe schools can become important platforms for movement education, exercise, postural awareness, physical fitness, injury prevention, ergonomics, early screening and health promotion.
The larger message is that back pain should not be viewed as an inevitable problem of growing older.
Musculoskeletal health begins in childhood, and prevention should begin before pain becomes persistent.
Regular movement, physical fitness, strength and flexibility can help children develop healthy movement habits and support their musculoskeletal health as they grow.

A child's lungs continue to develop well into adolescence, laying the foundation for respiratory health throughout life. When children grow up with smaller lung capacity, it means their lungs are unable to reach their full growth potential.
This can affect how efficiently the body takes in oxygen and may influence physical stamina, exercise tolerance and overall well-being. While the consequences are not always immediately visible, lung health in childhood can shape respiratory health decades later.
Lung development is influenced by several factors, beginning even before birth. Premature birth and low birth weight can affect early lung growth. During childhood, recurrent respiratory infections, poorly controlled asthma, exposure to tobacco smoke and prolonged exposure to air pollution may also influence lung function.
Nutrition, physical activity and genetic factors can contribute to differences in lung capacity between children.
Some children may have reduced lung function without obvious symptoms. Others may show signs during physical activity or respiratory infections.
Parents may notice:
These symptoms can occur with several respiratory conditions, so they should not automatically be attributed to low fitness or smaller lungs.
Management depends on why lung function is reduced. When asthma or another airway condition is present, appropriate inhaled medicines can help control inflammation and improve breathing. Children with specific chronic respiratory conditions may benefit from supervised breathing exercises, respiratory physiotherapy or pulmonary rehabilitation.
Where poor nutrition or inadequate growth is a contributing factor, nutritional support may also be recommended. The focus is not simply on increasing lung capacity, but on treating the underlying condition and helping the child achieve the best possible lung function for their age and health.
Several everyday measures can support respiratory health while the lungs are developing. Regular age-appropriate physical activity, adequate nutrition and sufficient sleep are important.
Eliminating and reducing exposure to cigarette smoke, indoor pollutants and poor outdoor air quality can also help immensely. Recommended vaccinations and timely treatment of respiratory infections may further reduce the impact of preventable illness.
Persistent respiratory symptoms, repeated chest infections, unexplained exercise intolerance, or a history of premature birth may warrant medical evaluation.
Depending on the child's age and symptoms, assessment may include a physical examination, oxygen measurement, lung function tests such as spirometry and Forced Oscillometry testing to identify the underlying cause and help determine whether medication, respiratory therapy, nutritional support, or other interventions are appropriate. In addition, sometimes undetected cardiac issues could be contributing and need attention and evaluation.
Childhood is an important period for establishing lifelong respiratory health. Minimizing exposure to harmful pollutants, encouraging physical activity and addressing respiratory problems early can help children reach their individual lung growth potential. The aim is not simply to measure how much air the lungs can hold, but to ensure they function as effectively as possible throughout childhood and into adulthood.
Food plays a very important role in this, as the saying goes, “we are what we eat”. Staying close to home-cooked, uncomplicated food is the key rather than app-based fast-food cravings.

Rare infections transmitted from a pregnant woman to her baby may be linked to a higher risk of autism and intellectual disability, according to a large new study.
Researchers at the Karolinska Institutet in Sweden found that children with congenital TORCH infections had about three times the risk of autism compared with children without these infections.
TORCH refers to infections that can be transmitted from mother to foetus during pregnancy, including:
These infections can cross the placenta and infect the developing fetus.
“It is important to emphasize that it is unusual for these infections to be transmitted from mother to child. They account for a very small proportion of all cases of autism in the population, but for those children who are actually affected, we see a clearly elevated risk of both autism and intellectual disability,” said Reneé Gardner, a researcher at the Department of Global Public Health at Karolinska Institutet.

Published in JAMA Pediatrics, the study analysed data from 3.7 million people born in Sweden between 1987 and 2021. Of these, 975 had a diagnosed congenital TORCH infection. The participants were followed for up to three decades.
Compared with children without a congenital TORCH infection, those with one were:

The researchers also compared children with TORCH infections with their unaffected siblings to assess whether shared family factors could explain the findings.
The results were similar, suggesting that the associations were not explained solely by factors shared within families.
No clear association was found between TORCH infections and ADHD or obsessive-compulsive disorder. However, children with the infections had poorer academic performance on average, even when they did not have an autism or intellectual disability diagnosis.
“Although these congenital infections are rare, some of them can be prevented, which makes them important from a public health perspective,” Gardner said.
The researchers also noted that rubella has virtually disappeared in Sweden following the introduction of national vaccination program. The prevention also depends on the infection:
