Frequent infections are one of the most common reasons parents worry — and one of the most common normal experiences of early childhood. A young immune system needs repeated exposure to build up its defences, especially once a child starts mixing with other children. Most infections are mild, common, and resolve on their own. Here's a breakdown by type.
Respiratory Infections
Common Cold
Caused by various viruses, colds cause a runny/blocked nose, sneezing, mild cough, and sometimes a low-grade fever. Young children average several colds a year — this is normal, especially in the first years of daycare or school. Treatment is supportive: fluids, rest, saline nasal drops, and fever management if needed.
Cough & Bronchiolitis
Viral infections can cause coughing that lingers for 2-3 weeks even after other symptoms resolve. In infants, a virus called RSV commonly causes bronchiolitis — wheezing and rapid breathing — which is usually mild but occasionally needs medical attention, especially in very young or premature babies.
Sore Throat & Tonsillitis
Most sore throats are viral and resolve within a few days. A small proportion are caused by bacteria (such as Strep throat), which may need antibiotics — features like high fever, white patches on the tonsils, and absence of cough can suggest this, but a doctor's assessment (sometimes with a throat swab) is the reliable way to tell.
Ear Infections
Middle ear infections (otitis media) are very common in young children, often following a cold. Signs include ear pain (younger children may tug at the ear or be unusually fussy), fever, and sometimes fluid drainage from the ear. Many resolve on their own, though your doctor will assess whether antibiotics are needed based on age, severity, and findings on examination. Recurrent ear infections can sometimes affect hearing temporarily — relevant to development, see our guide on speech delay in children.
Digestive Infections (Gastroenteritis)
Usually viral, causing vomiting and/or diarrhoea, often with mild fever, lasting a few days. Spreads easily in group settings through contaminated surfaces or hands. The main concern is dehydration — see our guide on gastroenterology problems in children for warning signs and fluid management.
Skin Infections
- Impetigo — a bacterial skin infection causing honey-coloured crusted sores, common around the nose and mouth, spreads easily through contact, treated with topical or oral antibiotics
- Fungal infections — such as ringworm (a fungal infection, not a worm) causing circular, scaly patches, treated with antifungal creams
- Head lice — extremely common in school-age children, causes itching, spreads through direct head-to-head contact, treated with specific shampoos/lotions and is not a sign of poor hygiene
Viral Rashes (Exanthems)
Several common childhood viruses cause characteristic rashes:
- Chickenpox — itchy blister-like rash, now less common where varicella vaccine is used
- Hand, foot, and mouth disease — small blisters on hands, feet, and inside the mouth, common in young children, usually mild
- Roseola — high fever followed by a rash as the fever breaks, common in infants/toddlers
- Measles — fever, cough, red eyes, and a spreading rash; can cause serious complications, which is why MMR vaccination is so important (see our vaccination guide)

Prevention
- Handwashing — one of the single most effective ways to reduce infection spread
- Vaccination — protects directly against several serious infections (measles, whooping cough, pneumococcal disease, and more)
- Avoiding close contact when sick — where practical, keeping a sick child home reduces spread to others
- Good nutrition and sleep — support overall immune function (see our guides on nutrition and sleep)
- Not sharing personal items — combs, hats, water bottles, utensils
When to Seek Medical Care
Most infections can be managed at home with rest, fluids, and time. See a doctor if there's high or persistent fever, difficulty breathing, signs of dehydration, a rash that doesn't fade when pressed, severe pain, or if your child seems unusually unwell, lethargic, or is not improving as expected. Our guide on when to see a pediatrician covers this in more detail by age and symptom.
