About

About Children's health

We treat all kinds of childhood illness, including fever, cough, runny nose, rashes and tummy trouble. The whole family can also be seen together.

Why it happens

Children's immune systems are still developing, and group settings such as nursery and school give many chances to catch infections, so they often get fevers, coughs and diarrhea again and again. Because their bodies are small and have little fluid in reserve, they become dehydrated from vomiting or diarrhea faster than adults. Most recover on their own, but the younger the child, the more closely they need to be watched.

What's happening in the body

Children's bodies are not the same as adults'. Water makes up a larger share of their body weight and their metabolism is more active, so dehydration from vomiting, diarrhea or fever develops quickly. Dehydration that would take several days in an adult can become a problem in half a day in babies and toddlers. Their temperature control is also immature, so they tend to run high fevers with infections, but the height of the fever doesn't necessarily match how serious the illness is. Their immunity, too, is built up by meeting many germs one after another after birth, so getting repeated infections after starting group care is a natural process. In the ears, the tube connecting the back of the nose to the middle ear is short and nearly horizontal, which makes middle ear infections more likely after a cold. We take these differences into account and assess children differently from adults.

Main symptoms

  • Fever (mood, appetite and fluid intake are important signs to watch)
  • Cough, runny nose, sore throat
  • Vomiting, diarrhea, stomach pain
  • Rash (all over, inside the mouth, on the hands and feet, etc.)
  • Complaining of ear pain or often touching the ear
  • Poor appetite, low energy
  • Fast breathing, or heaving shoulders when breathing
  • Won't stop crying, or not their usual self

When you can wait and see

What you can do yourself

  • Give small amounts of fluid often (oral rehydration solution may help)
  • If your child has a fever but is in good spirits and drinking, stay calm and keep an eye on them
  • Don't overdress or overcool your child, and change their clothes if they sweat
  • Offer what they can eat, without forcing it
  • Keep a record of symptoms, temperature, fluid intake and how often they pass urine

Please consult us

If any of the following apply

  • Your child has a fever or is unwell
  • You're not sure where to go at night or on a holiday
  • You want siblings to be seen at the same time

Seek care right away

If any of the following apply

  • Seems to be struggling to breathe (heaving shoulders, skin pulling in between the ribs, flaring nostrils)

Differential

Telling it apart from similar conditions

Symptoms that look the same may need different care depending on the cause. Use this as a guide to find what's closest to your situation.

Colds and viral infections

Clues

In reasonable spirits and drinking, with a runny nose or cough

Care

Mainly monitoring at home

Dengue

Clues

High fever, pain behind the eyes and a rash, with likely mosquito bites

Care

A blood test is needed. Seek care urgently if there is stomach pain or repeated vomiting

Gastroenteritis

Clues

Vomiting first, followed by diarrhea

Care

Preventing dehydration comes first

Middle ear infection

Clues

After a cold, touching the ear, fussy and crying at night

Care

We check the eardrum

Urinary tract infection

Clues

Ongoing fever with no other symptoms (especially in babies and toddlers)

Care

It needs to be assessed with a urine test

Emergencies

Clues

Listless and slow to respond, seizures, fast breathing, or bluish-purple lips

Care

Consider emergency services immediately

* This is not a complete list. If you're not sure, please consult us.

Course

Typical course

This is the general course. Actual progress varies from person to person.

  1. Days 1–2 of the fever

    The fever rises and your child becomes fussy

    Rather than how high the fever is, watch whether your child is drinking and responds normally

  2. Day 3

    With most viral infections, the fever starts to come down around now

    Please consult us if the fever hasn't gone down after 3 days

  3. Days 4–5

    A rash may appear after the fever goes down

    If there's only a rash and your child is lively, you can usually just keep an eye on it

  4. If it lasts 5 days or more

    Another cause needs to be considered

    An assessment by a doctor is recommended

Local Insight

For people living in Southeast Asia

The climate, healthcare and access to medication differ from Japan. Here are points specific to this region.

01

In Southeast Asia, hand, foot and mouth disease occurs all year round, and severe cases have been reported with enterovirus 71, one of the viruses that cause it. Singapore and some other places have set rules for returning to nursery, which may differ from Japan's.

02

Children can also get dengue, and warning signs such as persistent vomiting, severe abdominal pain and bleeding may appear around the time the fever goes down. Unlike what people in Japan might expect, a fever going down doesn't necessarily mean all is well.

03

Routine vaccinations differ in type and timing between Japan and local countries (for example, how BCG and Japanese encephalitis are handled), and international and local schools may ask you to submit vaccination records. It's reassuring to have both your Maternal and Child Health Handbook and vaccination records in English.

04

In hot tropical environments, dehydration from fever or diarrhea can develop quickly. The gap between constant air conditioning indoors and the heat outside can also make children unwell.

Care

What Cotovia can do

  • Assessing your symptoms through a consultation
  • Prescribing medication for children (prescribing is at the doctor's discretion)
  • Advice on when to see a doctor and how to care for your child at home
  • Advice on how to get care in an emergency at night

Tests you may have

Not knowing what will happen can make people hesitate to seek care, so here's what actually takes place.

Consultation

Checking overall condition, throat, ears, tummy and skin

A few minutes We take care not to frighten your child

Rapid test

Identifying flu, strep throat and similar infections

About 15 minutes A swab of the nose or throat

Blood test

Assessing possible infections such as dengue, dehydration and inflammation

Blood draw takes a few minutes Blood draw

Urine test

Checking for urinary tract infection

A few minutes A urine sample, collected in a way suited to your child's age

Treatment options

Fluids and electrolytes

Prevents dehydration

This is the most important part of treating children. Give small amounts, many times

Fever reducers

Eases discomfort and makes it easier to drink

The aim isn't to bring the temperature down for its own sake. Stick to the dose for your child's age and weight

Symptom relief

Eases symptoms such as cough and runny nose

Which medications can be used depends on age

Antibiotics

Used when a bacterial infection is confirmed

They don't work on viral infections. The doctor decides whether they are needed

* Tests, procedures and prescriptions are decided by the doctor after a consultation. Services may vary by country and location.

Preparation

Before your visit

When seeing a doctor abroad, simply organizing what you need to say makes a big difference.

What to tell us

  • When the fever started and how high it is
  • Whether your child is drinking and passing urine

Self Care

What you can do yourself

Along with seeing a doctor, here are things to keep in mind in daily life.

Prevention

  • Plan vaccinations (be aware of differences between the local and Japanese schedules)
  • Build the habit of handwashing
  • Use insect repellent (to prevent mosquito-borne infections)
  • Be careful about food and drinking water hygiene

FAQ

FAQ

Common questions before a visit, and common assumptions that lead people to judge for themselves.

QCan siblings be seen together?
A

Yes. The family can consult together. We may ask you to register each person separately.

QWhen should I see a doctor if my child has a fever?
A

Besides the temperature itself, important signs are whether your child is drinking, what their mood is like and whether they are passing urine. For babies under 3 months old with a fever, seeing a doctor early is recommended.

QI'm worried because the local vaccination schedule is different from Japan's.
A

If you show us your Maternal and Child Health Handbook and local vaccination records, we can discuss how to proceed, including what to do after returning to Japan.

QMy child's fever has gone down, but they still seem unwell.
A

Some infections cause symptoms after the fever goes down. With dengue, extra care is needed after the fever breaks, so please consult us if your child doesn't seem like their usual self.

Common misconceptions

Myth The higher the fever, the more serious the illness

Fact How high a fever is doesn't match how serious the illness is. Whether your child is listless or drinking are more important signs

Myth You should bring a fever down right away

Fact Fever is also part of the body's defenses. Fever reducers are used to ease discomfort and make it easier to drink

Myth You can give a smaller dose of adult medicine

Fact Some ingredients can't be used at certain ages. Always use children's medicine at the dose for your child's weight

Myth No baths when your child has a fever

Fact If your child is lively, a short bath to keep clean is fine

Myth Children who often catch things at nursery have a weak constitution

Fact Getting repeated infections after starting group care is a natural part of building immunity
