Children get sick, it’s part of growing up. From sniffles to tummy bugs, most common childhood illnesses are mild and pass quickly. But as a parent, knowing when to care for your child at home and when to see your GP can make all the difference.
Suppose you are a parent in Branxton, Hunter Valley, or the surrounding NSW areas. In that case, you have probably wondered about those persistent coughs, mysterious rashes, or sudden fevers that seem to pop up out of nowhere. The good news? Most common childhood illnesses are manageable with the right knowledge and care.
If you’re ever unsure about your child’s symptoms, our GPs at Branxton Healthcare are here to help. We provide family-friendly care for common childhood illnesses across Branxton and the Hunter Valley.
What Are the Most Common Childhood Illnesses?
Australian children typically encounter several common childhood illnesses during their early years. These conditions affect millions of kids nationwide and are especially frequent in daycare and school settings where germs spread quickly.
Understanding these common childhood illnesses and symptoms helps you respond confidently when your little one isn’t feeling well. Here’s what every parent should know about the most frequent health issues affecting children aged 0-12 years.
The Big Five Common Childhood Illnesses
1. Common Cold and Flu
- Affects 6-8 times per year in young children
- More frequent during NSW’s cooler months (May-September)
- Usually resolves within 7-10 days
2. Gastroenteritis (Stomach Bug)
- Often called “gastro” in Australia
- Highly contagious in group settings
- Can cause dehydration quickly in small children
3. Ear Infections
- Very common in children under 5
- Often follows cold symptoms
- It can affect hearing temporarily
4. Skin Conditions and Rashes
- Includes eczema, chickenpox, and hand-foot-mouth disease
- More common in warmer months in the Hunter Valley
- Usually treatable at home
5. Respiratory Issues
- Includes persistent coughs, bronchiolitis, and croup
- Can be triggered by NSW’s dust and pollen
- Night-time coughing often worries parents most
Recognising Early Signs of Common Childhood Illnesses
Spotting symptoms early makes a huge difference. Children can’t always tell you exactly how they feel, so watching for these signs helps you act quickly.
Fever in Children – When to Worry
Fever is your child’s natural response to infection. Most childhood common illnesses start with a temperature, but not all fevers need immediate medical attention.
Normal fever management:
- Temperature under 38.5°C can often be managed at home
- Keep your child hydrated (especially important in Branxton’s hot summers)
- Light clothing and cool baths help comfort
When fever becomes concerning:
- Temperature above 39°C that doesn’t respond to paracetamol
- Fever lasting more than 3 days
- Your child is unusually drowsy or difficult to wake
- Difficulty breathing or unusual crying patterns
Persistent Cough in Children
“My child is coughing at night – what should I do?” is one of the most common questions we hear from Hunter Valley parents.
Coughs accompany many common childhood illnesses and symptoms, but here’s how to tell if it’s serious:
Manageable coughs:
- Dry cough following a cold
- Cough that’s worse at night but improves during the day
- A child can still play and eat normally
Concerning coughs:
- Barking cough (could indicate croup)
- Wheezing sounds
- Cough with green or blood-stained mucus
- A child is struggling to breathe
Rashes and Skin Changes
Skin problems are among the most common childhood illnesses. While many rashes look alarming, most aren’t dangerous.
Common harmless rashes:
- Heat rash (common in NSW summers)
- Mild eczema flare-ups
- Minor allergic reactions
Rashes needing GP attention:
- Purple or red spots that don’t fade when pressed
- Widespread rash with fever
- Blistering or weeping sores
Specific Common Childhood Illnesses: What Every Parent Needs to Know
Chickenpox Symptoms in Children
Chickenpox remains one of the most recognisable common childhood illnesses, though it’s less common thanks to vaccination programs.
Timeline and symptoms:
- Starts with fever and feeling unwell
- Red spots appear 1-2 days later
- Spots become fluid-filled blisters
- Eventually crust over (usually after 5-7 days)
Home care for chickenpox:
- Keep fingernails short to prevent scratching
- Cool baths with bicarbonate of soda
- Calamine lotion for itching
- Keep the child home until all blisters have crusted over
Hand, Foot and Mouth Disease
This viral infection is increasingly common in Australian daycares and schools.
Key symptoms:
- Small blisters on hands, feet, and mouth
- Fever and sore throat
- Loss of appetite due to mouth pain
Management tips:
- Soft foods and cold drinks
- Pain relief with children’s paracetamol
- Usually resolves within 7-10 days

Symptoms to watch for:
- Vomiting and diarrhoea

Home treatment:

- Gradually reintroduce bland foods
- Rest and comfort
When to see a doctor:

FAQ’s:
What are the most common childhood illnesses?
The top common childhood illnesses in Australia include colds, flu, gastroenteritis, ear infections, and skin conditions like chickenpox. Most children experience 6-8 colds yearly, especially in daycare settings.
When should I see a GP for my child’s fever?
See a doctor if fever exceeds 39°C, lasts more than 3 days, or if your child seems unusually drowsy. For babies under 3 months, any fever above 38°C needs immediate attention.
Can I send my child to school with a cold?
Keep children home if they have fever, are coughing frequently, or feel too unwell to participate. A clear runny nose alone usually doesn’t require staying home from school.

Most common childhood illnesses resolve within 7-10 days. Colds last 7-10 days, gastro lasts 3-5 days, and chickenpox takes 5-7 days from first spots to crusting.
What natural remedies help with childhood illnesses?
Honey works for coughs (over 12 months), cool mist humidifiers ease congestion, and plenty of rest helps recovery. Always combine natural remedies with proper medical care when needed.
How can I prevent childhood illnesses spreading at home?
Practice good hygiene – frequent handwashing, separate utensils, clean surfaces regularly, and teach children to cough into their elbow. Keep sick children’s belongings separate until recovery.
