There are few messages that make parents’ hearts sink faster than:
“Just a heads up, parents, there’s a bug going around in the class…”
If your child is in school, illness outbreaks are honestly part of the parenting experience. One child arrives with “a runny nose,” and three days later, half the class is off sick, the teacher sounds exhausted, and someone in the WhatsApp group is asking if green snot means antibiotics.
Luckily, most childhood illnesses are mild and can be managed at home. But some spread very quickly through schools and creches, and a few need earlier medical attention.
This guide focuses specifically on the contagious illnesses parents most often hear about during school and creche outbreaks, what symptoms to look for, when your child should stay home, and when it’s time for a clinic visit.
The School and Creche Illness Alerts Parents See Often
Schools and creches are basically tiny germ-sharing festivals. Young children touch everything, forget to wash their hands properly, share toys constantly, and somehow manage to cough or sneeze directly into somebody else’s face. Add close contact and still-developing immune systems, and it becomes very easy for illnesses to move through an entire class surprisingly quickly, especially during the early preschool years when children seem to catch every bug going around.
And once one child gets sick, it often feels inevitable that everybody else will follow. Parents start comparing symptoms at pickup, siblings bring viruses home, and suddenly the whole family is surviving on toast, Panado, and very little sleep.
The illnesses below are some of the most common outbreak-style illnesses parents suddenly hear about at school or creche.
RSV: The Viral Illness Behind the “Bad Cough Going Around”
There always seems to be one cough that absolutely flattens households.
RSV stands for respiratory syncytial virus, and it’s one of the most common viral illnesses affecting babies and young children.
RSV is also one of those illnesses that often starts looking “not too bad” during the day, then suddenly sounds dramatically worse at 2 am when nobody is emotionally prepared for wheezing noises.
Why RSV suddenly seems to be everywhere
RSV spreads easily through coughing or sneezing, shared surfaces, and close contact. Schools, creches, birthday parties, and siblings help RSV move around very efficiently.
Most older children recover well. Babies and younger toddlers can become much sicker.
What RSV symptoms look like in babies and children
RSV often starts like a normal cold with:
Runny nose,
Fever,
Cough,
Irritability,
And reduced appetite.
In some children, especially babies, symptoms can progress to:
Wheezing,
Fast breathing,
Chest pulling,
Feeding difficulties,
Or exhaustion from coughing.
Signs your child may be struggling to breathe
Seek medical attention urgently if your child has:
Fast or laboured breathing,
Chest pulling,
Flaring nostrils,
Blue lips,
Pauses in breathing,
Or difficulty feeding because of breathing effort.
Babies and children with breathing difficulty should be medically assessed promptly. Trust your instincts if your child seems unusually unwell, especially if symptoms are worsening, feeding becomes difficult, or breathing starts looking harder than normal.
RSV can be more serious in some children
RSV can be more dangerous for:
Babies under 1 year,
Premature babies,
Children with lung conditions,
Children with heart conditions,
And some medically vulnerable children.
⚠️ Important: most children recover well from RSV
RSV sounds frightening because parents hear about it so often on social media, but the reality is that most children recover well with supportive care at home.
Like many viral illnesses, there is no specific “cure” for RSV itself. Treatment is mainly focused on keeping children comfortable, supporting hydration, monitoring breathing, and helping them get enough oxygen if breathing becomes difficult.
Most children do not need hospital admission, but babies, younger infants, and some medically vulnerable children may become more unwell and need closer monitoring.

Hand, Foot, and Mouth Disease: The Rash Spreading Through Creches and Schools
Hand, foot, and mouth disease (HFMD) is one of those illnesses many parents have never heard of until it suddenly sweeps through the toddler class. And it sounds super scary, but it's usually not serious and often resolves on its own.
HFMD is caused by a virus and spreads very easily through saliva, mucus, coughing, sneezing, shared surfaces, and close contact between children. HFMD spreads extremely easily between young children, which is why outbreaks can move through a creche or toddler class surprisingly quickly.
The symptoms parents usually notice first
HFMD often starts with:
Fever,
Tiredness,
Reduced appetite,
Sore throat,
And painful mouth ulcers.
A rash usually follows, commonly appearing on:
The hands,
Feet,
Around the mouth,
And sometimes the bum or legs.
Some children remain fairly playful. Others become miserable mainly because the mouth ulcers hurt so much that eating and drinking become uncomfortable.
When children with HFMD can go back to school
Children with hand, foot and mouth disease are usually most contagious during the first few days of illness. Most children can return to school or creche once:
They are fever-free,
Feeling well enough to participate normally,
And able to eat and drink comfortably again.
Some children may still have a mild rash or peeling skin after they are no longer significantly contagious, which is quite common during recovery.
When parents should worry about HFMD
Get medical advice if your child:
Is refusing fluids,
Has signs of dehydration,
Becomes unusually sleepy,
Struggles to breathe,
Or seems significantly more unwell than expected.

The Measles Outbreak in Schools: Symptoms Parents Should Not Ignore
A measles outbreak creates panic, and for good reason. Measles spreads extremely easily and can become serious, especially in babies, young children, pregnant women, and vulnerable individuals.
Even brief exposure can spread the virus.
Why measles outbreaks are taken so seriously
Measles is one of the most contagious illnesses in the world. A child with measles can spread the virus before the classic rash even appears. That means outbreaks can move rapidly through schools and communities before parents even realise what is happening.
Early measles symptoms parents may miss
One of the difficult things about measles is that it often starts looking like a regular viral illness. Early symptoms commonly include:
Fever,
Cough,
Runny nose,
Red eyes,
Tiredness,
And general flu-like symptoms.
The rash usually develops later.
Because the early symptoms can look “viral,” measles is sometimes missed initially during outbreaks, especially before the rash appears.
When parents should worry about measles
Children with suspected measles should be medically assessed promptly, especially if they have:
Breathing difficulty,
Dehydration,
Severe lethargy,
Poor feeding,
Or worsening symptoms.
Vaccination remains one of the most important ways to reduce severe measles illness and outbreaks.
Chickenpox: The Itchy Rash That’s Making a Comeback at Schools in South Africa
Even though chickenpox vaccines are becoming more common, outbreaks are still happening in our schools, especially in younger children.
Chickenpox is extremely contagious and often spreads before parents even realise a child is sick, which is why one confirmed case at school can quickly turn into multiple children developing the same rash over the next week or two.
What chickenpox usually looks like
Chickenpox often starts with children seeming slightly tired, grumpy, feverish, or off their food before the rash becomes obvious. The rash usually begins as small red spots that quickly develop into itchy fluid-filled blisters.
Parents commonly notice:
Itchy red spots, that start on the chest, back, and face
Fluid-filled blisters,
Spots appearing in waves over several days,
Fever,
Tiredness.
The spots eventually dry out and crust over as the illness improves.
When children with chickenpox can go back to school
Children with chickenpox are usually contagious from about 1–2 days before the rash appears until all the spots have dried out and crusted over completely. Because chickenpox spreads so easily through schools and creches, children should stay home while new blisters are still appearing or any spots remain wet and fluid-filled.
Most children can return to school once:
All the blisters have crusted over,
No new spots are appearing,
And they feel well enough to participate in normal activities again.
When parents should worry about chickenpox
Most children recover well from chickenpox at home, but some symptoms can suggest a child needs medical assessment sooner.
Parents should seek medical attention if a child develops:
Breathing difficulty,
Severe lethargy,
Dehydration,
Unusually painful or infected-looking skin,
Or symptoms that seem to be worsening instead of improving.
Extra caution is also important in babies, medically vulnerable children, pregnant women, or children with weakened immune systems.
Impetigo (“School Sores”): The Crusty Sores Parents Often Notice Around the Nose and Mouth
Impetigo, often called “school sores,” is a very contagious skin infection commonly seen in younger children. It often starts as what looks like a small irritated patch of skin or a few harmless-looking sores around the nose, mouth, or exposed areas of the body. Because the early spots can look quite mild, parents sometimes mistake them for:
Insect bites,
Scratches,
Eczema,
Or random scabs at first.
Then over a few days, the sores often become more crusty, irritated, and noticeably spread to nearby skin.
What impetigo (“school sores”) usually looks like
One of the reasons impetigo is often missed early is because it does not always start looking dramatic. Parents may first notice a small irritated patch of skin, a sore that looks slightly crusty, or what seems like a healing scrape around the nose or mouth.
As impetigo develops, the sores often become:
Red and irritated,
Crusty or scabbed over,
Honey-coloured,
Or appear as spreading patches around the nose, mouth, or other exposed areas of skin.
The sores can spread quite quickly, especially when children scratch or touch the affected skin frequently.
When impetigo needs treatment
Because impetigo is a bacterial skin infection and spreads very easily between children, medical treatment is usually required, especially once the sores start spreading, becoming more crusted, or appearing in multiple areas.
Treatment may include:
Antibiotic cream or ointment for smaller areas,
Oral antibiotics for more widespread infections,
And gentle cleaning of the affected skin.
Without proper treatment, impetigo can continue spreading to nearby skin or other children through close contact, scratching, and touching the sores.
When children with impetigo can go back to school
Because impetigo spreads so easily, children should usually stay home until they have started antibiotic treatment and the sores are no longer actively weeping or spreading.
In many cases, children can return to school or creche about 24 hours after starting appropriate treatment, especially if the sores are drying out, improving, and can be properly covered if needed.
Good handwashing and avoiding touching or scratching the sores also help reduce the risk of spreading impetigo to other children.
Conjunctivitis (“Pink Eye”): The Eye Infection That Spreads Fast at School
Few school illnesses spread faster than conjunctivitis. One child arrives with a slightly pink eye, and suddenly, half the class looks suspiciously watery by Friday afternoon.
There’s also always that moment where parents convince themselves it’s “just tired eyes” before the second eye joins the party a few hours later.
Pink eye symptoms parents usually notice first
Parents commonly notice:
Red or pink eyes,
Watery eyes,
Sticky discharge,
Crusting after sleep,
Itching,
Or swollen eyelids.
Some children barely seem bothered. Others wake up looking like they lost a fight with a glitter glue factory overnight.
Viral vs. bacterial pink eye
Not all conjunctivitis is the same. Pink eye can either be caused by a virus or a bacteria. Viral conjunctivitis is often linked to colds or other viral illnesses spreading around schools and creches. It usually causes:
Watery eyes,
Redness,
Irritation,
And mild crusting.
It often starts in one eye before spreading to the other and usually improves on its own with time.
Bacterial conjunctivitis is more likely when children develop:
Thick yellow or green discharge,
Sticky eyelids that keep sealing shut,
Worsening swelling,
Or heavier discharge throughout the day.
Bacterial cases are more likely to need antibiotic eye drops or ointment, especially when symptoms are worsening or not improving. Keeping the eyes clean, encouraging good handwashing, and avoiding shared towels can help reduce the spread while children recover.
When children can return to school after having pink eye
Pink eye is usually most contagious while eyes are actively red, watery, or producing discharge, especially when children are still rubbing their eyes frequently. Children with ongoing thick discharge or significant eye irritation spread conjunctivitis more easily because germs transfer quickly through hands, shared surfaces, and close contact.
Once discharge has stopped, redness is improving, and children are able to avoid constant eye rubbing, the risk of spreading conjunctivitis becomes much lower, and many children can return to normal activities safely.
Head Lice at School: The Notification Every Parent Dreads
Few school notifications create more instant parental stress than a head lice alert. Suddenly, every parent is checking scalps under bright bathroom lights while questioning every tiny white speck they find.
Why lice outbreaks are so frustratingly common
Head lice are incredibly common in schools and younger age groups where children play closely together and share personal space constantly. Lice spread mainly through close head-to-head contact and honestly do not care whether hair is clean, dirty, long, short, curly, straight, or freshly washed with shampoo that costs more than your monthly coffee budget.
The head lice signs parents usually notice first
For many parents, the first clue is not actually seeing lice. It’s noticing a child scratching more than usual during the day, complaining about an itchy scalp at bedtime, or getting a message from school that there has been a case in the class. Parents may notice:
Itching or scratching,
Small white nits attached to hair shafts,
Or live lice moving near the scalp.
Some children barely itch at all, which is one reason head lice outbreaks can spread through classrooms before anyone realises they are there.
What actually works for treating lice
Treating head lice can feel overwhelming at first, especially during bigger school outbreaks. Fortunately, treatment is usually very simple once parents know what to focus on. Successful treatment usually involves:
Proper lice treatment products,
Thorough combing,
Treating close contacts if needed,
And repeating treatment correctly.
Cleaning hairbrushes, bedding, and recently used hats can help, but panic-cleaning the entire house is usually far less important than treating the hair properly and consistently.
When children with head lice can return to school
Unlike many contagious childhood illnesses, children with head lice do not usually need to stay home for long periods once treatment has started. In most cases, children can return to school or creche after the first proper treatment has been done.
The biggest focus should be:
Starting treatment promptly,
Removing lice and nits as thoroughly as possible,
And continuing follow-up treatment correctly.
Because lice spread mainly through close head-to-head contact rather than jumping around classrooms, prolonged exclusion from school is usually not needed once treatment is underway.
When a School or Creche Illness Needs Medical Attention
Many childhood illnesses improve with rest, fluids, and supportive care at home. But there are times when children need medical attention sooner, especially if symptoms are becoming more severe, changing quickly, or your child seems much more unwell than you would normally expect from an ordinary viral illness.
Parents should seek medical attention if a child develops:
Breathing difficulty or blue lips,
Persistent vomiting or dehydration,
Unusual sleepiness,
Seizures,
Severe pain,
A stiff neck,
A rapidly worsening rash,
Or a fever that is becoming difficult to manage.
Trust your instincts. Parents are often very good at recognising when something simply does not seem right.
💗 If your baby or child seems unusually unwell, you can book a sick baby or child visit at Mums & Bums for an assessment and personalised advice.
Why It Can Feel Like Children Are Always Catching Something
If it feels like children are constantly bringing home a new cough, rash, fever, or runny nose from school or creche, you are definitely not imagining it. Group settings naturally make it easier for viruses and infections to spread, especially in younger children who are still building immunity to many common childhood illnesses.
Illness outbreaks also tend to move in waves throughout the year, particularly after holidays, during seasonal changes, or when children are newly exposed to larger school or creche environments.
For many families, the first few years in group care are often the busiest illness years. The reassuring part is that this does usually improve over time as children’s immune systems gain experience with common viruses and infections.

Common Questions About School Illness Outbreaks
What illness is currently going around schools in South Africa?
Common school and creche outbreaks in South Africa include RSV, hand, foot, and mouth disease, conjunctivitis, measles, head lice, chickenpox, impetigo, and other viral infections that spread easily between children.
What are the first signs of RSV in children?
RSV often starts like a cold with a runny nose, cough, fever, and reduced appetite. Some children, especially babies, may later develop wheezing, fast breathing, chest pulling, or feeding difficulties.
How contagious is hand, foot, and mouth disease?
Hand, foot, and mouth disease spreads very easily through saliva, coughing, sneezing, mucus, and contaminated surfaces. Children are usually most contagious during the first few days of illness.
Can adults catch childhood viruses from kids?
Yes. Adults can catch many childhood viruses from children, including RSV, hand, foot, and mouth disease, conjunctivitis, and stomach viruses. Symptoms in adults are sometimes milder, but not always.
When should sick children stay home from school or creche?
Children should usually stay home if they have a fever, vomiting, diarrhoea, contagious rashes, significant conjunctivitis, or illnesses spreading easily to other children.
Does pink eye always need antibiotics?
No. Many cases of pink eye (conjunctivitis) are viral and improve without antibiotics. Bacterial conjunctivitis is more likely when there is thick yellow or green discharge and worsening swelling or redness.
How does head lice spread so quickly?
Head lice spread mainly through close head-to-head contact between children. Schools and creches make this easier because children play closely together.
What does impetigo (“school sores”) look like?
School sores, also called impetigo, often appear as red sores, crusty patches, or honey-coloured scabs, usually around the nose and mouth.
When should I worry about a rash or cough?
Parents should seek medical attention if a child has breathing difficulty, dehydration, worsening rash, severe lethargy, blue lips, or symptoms that are rapidly getting worse.
When should I seek urgent medical attention for a sick child?
Urgent medical attention is needed for breathing difficulty, seizures, dehydration, severe lethargy, blue lips, stiff neck, or a child who seems unusually unwell or difficult to wake.
