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

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.

Good Hygiene

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.

The Hygiene Hypothesis: Does Exposure to Germs Strengthen Immunity?

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.

Cleaning and Sanitizing Children’s Belongings

Regular cleaning of toys, school supplies, and frequently touched objects is essential. Understanding the difference between cleaning, sanitizing, and disinfecting can help:

• Cleaning removes visible dirt and debris.
• Sanitizing reduces germs to safer levels.
• Disinfecting kills germs completely, offering the highest level of protection.

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.

Choosing Effective Sanitizing Products

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.

Encouraging Good Hygiene Without Causing Anxiety

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.

Boosting Immunity Through Nutrition

A strong immune system helps children fight infections more effectively. Proper nutrition plays a crucial role in immune support. A balanced diet should include:

• Proteins
• Vegetables
• Fruits
• Healthy fats
• Carbohydrates
• Adequate hydration

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.

Teaching Respiratory Etiquette

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.

When Emily Hughes saw that her 18-month-old daughter, Scarlett, had a swollen knee in late 2023, she initially thought it might be an injury from the toddler’s routine playtime. Scarlett was energetic and adventurous, and the swelling did not appear to cause her pain.

But the swelling did not improve, and further examinations eventually led to a diagnosis of juvenile idiopathic arthritis (JIA), a chronic inflammatory condition that affects children.

Hughes, who lives in Australia, told Mamamia that several doctors initially found no cause behind her daughter’s symptoms. The situation changed in February 2024, when Scarlett’s knee became hot, painful and more severely swollen. She could no longer bear weight on the affected leg. “She wouldn’t bear weight, and it was even more swollen,” Hughes said.

Scarlett was taken to the Royal Children’s Hospital in Melbourne, where doctors initially thought it was septic arthritis, a serious joint infection. Investigations failed but the family continued consulting specialists.

By May, after other possible explanations got investigated, Scarlett was referred to a rheumatologist and diagnosed with juvenile arthritis affecting three joints.

Now four years old, Scarlett is in remission and has returned to physical activities like climbing and doing cartwheels. Her experience highlights why stubborn joint swelling and changes in a young child’s movement deserve emergency medical attention, even when the child is not in pain.

What Is Juvenile Idiopathic Arthritis?

Juvenile idiopathic arthritis is the most common form of chronic arthritis in children. It refers to a group of several conditions in which the immune system triggers inflammation in the joints by mistake. Although genetic and environmental factors may contribute, the exact cause is unknown.

The condition can affect children younger than 16 and may involve one or several joints. The knees, ankles, wrists and elbows are commonly affected.

Unlike arthritis, JIA can begin during toddlerhood. Its symptoms may also be difficult to recognise as young children cannot always describe pain, stiffness or discomfort accurately.

There is no single test that confirms JIA. Doctors start by assessing the child’s symptoms, medical history and physical examination, and may use blood tests and imaging to investigate inflammation and rule out other conditions.

According to the US National Institute of Arthritis and Musculoskeletal and Skin Diseases and the American Academy of Pediatrics, parents should watch for the following symptoms:

1. Continued joint swelling

A knee, ankle, wrist or other joint that remains swollen should be assessed on priority. In JIA, painless swelling may occur even when the child seems comfortable.

2. Morning stiffness

Children may struggle to move a joint after waking up or after sitting still for a long time. Stiffness may improve as they become more active during the day.

3. Limping or reluctance to walk

A toddler who starts limping, avoids putting weight on one leg or has difficulty walking may be experiencing joint inflammation.

4. Difficulty bending or straightening a joint

Limited movement is also one of the signs. A child may struggle to straighten an elbow, bend a knee or move a limb as freely as before.

5. Changes in play and everyday activities

A child who suddenly avoids climbing, running or playing, or struggles with activities they previously dud easily, may have pain or stiffness.

Some children with JIA may also experience fatigue, fever, rash or reduced appetite, depending on the type of disease. Untreated inflammation can damage joints and interfere with a child’s movement and development. Early diagnosis and treatment aim to control inflammation, maintain joint function and help children maintain their usual activities.

JIA can also affect the eyes. Some children develop uveitis, inflammation inside the eye that may cause no obvious symptoms initially but can threaten vision if left untreated. Regular eye examinations are therefore an important part of JIA.

For every woman pregnancy is a beautiful and dream journey, but from the perspective of heart-health , it acts as a “natural stress test” for the body. The best part is most women recover completely after childbirth. However, certain complications such as preeclampsia, high blood pressure, gestational diabetes, preterm delivery, or poor fetal growth can sometimes be early warning signs of future cardiovascular risk.

As a cardiologist, I want women to know that preeclampsia does not simply end when pregnancy ends. It can signal a higher risk of high blood pressure, diabetes, heart disease and stroke later in life. Gestational diabetes also increases future cardiometabolic risk.

This does not mean you will develop heart disease. It means you have an opportunity to be proactive.

What should be your postpartum action plan?

1. Check your blood pressure regularly, especially after preeclampsia or gestational hypertension.

2. Check blood sugar after gestational diabetes and continue recommended long-term screening.

3. Know your numbers: monitor cholesterol, weight and other cardiovascular risk factors.

4. Rebuild healthy habits: gradually return to regular exercise, eat a heart-healthy diet, avoid smoking and prioritise sleep.

5. Tell your doctor your pregnancy history—it is an important part of your lifelong heart history.

Your pregnancy may be over, but not your heart health journey, it continues for life time. Early awareness gives you the power to prevent problems before they begin.

Vaccination during pregnancy protects more than just the mother. Vaccines such as Td, Tdap, and influenza (when recommended) help pass protective antibodies to the baby, providing valuable immunity during the first six months of life.

When people think about vaccination, they usually think about babies receiving their first vaccines after birth. However, an important part of a child's protection actually begins during pregnancy.

Maternal immunisation helps protect both the mother and her baby by allowing protective antibodies to pass through the placenta before birth. These antibodies provide the newborn with temporary immunity during the first few months of life, when the baby's immune system is still developing and routine childhood vaccines have not yet become fully effective.

Despite its importance, awareness about maternal immunisation remains low, with many women knowing only about the Td vaccine while being unaware of the benefits of Tdap and influenza vaccination when recommended.

What is maternal immunisation?

Maternal immunisation refers to vaccines that are recommended during pregnancy to protect the mother from certain infections while also passing protective antibodies to the unborn baby.

During the third trimester, these antibodies cross the placenta and help protect the newborn from serious illnesses during the first six months of life. This protection is especially important because young infants are more vulnerable to infections and cannot receive all vaccines immediately after birth.

Important vaccines during pregnancy

Td (Tetanus and Diphtheria): The Td vaccine is routinely recommended during pregnancy. It protects the mother against tetanus and diphtheria while also helping protect the newborn from neonatal tetanus.

Tdap (Tetanus, Diphtheria and Pertussis): In many situations, doctors may recommend the Tdap vaccine during pregnancy. It also protects against pertussis (whooping cough), a highly contagious infection that can be life-threatening for young babies. Vaccination during pregnancy allows antibodies to reach the baby before birth, reducing the risk of severe illness in early infancy.

Influenza (Flu) Vaccine: Pregnant women are at a higher risk of developing complications from influenza. When recommended by the treating doctor, the influenza vaccine helps protect both the mother and the baby during flu season.

Why it matters for the newborn

A newborn's immune system is still immature, making babies more susceptible to infections. The antibodies received from the mother act as the baby's first shield against disease until the infant starts receiving routine childhood vaccines and develops their own immunity. This early protection can reduce the risk of severe infections during one of the most vulnerable stages of life.
