Childhood Illnesses You Should Learn About
July 20, 2020
Category: Childhood Illness,

Though most of the world has been following COVID-19 closely, as a parent, you should become familiar with  other illnesses that can affect you child beyond the  typical ear infectionscolds, and stomach bugs.

This blog is a summary of an article originally published by webMD.


Respiratory syncytial virus (RSV) is an infection of the airways. It usually isn’t serious, but if your child is under 2, or has a heart or lung disease or a weak immune system, it can inflame the lungs and cause pneumonia.


  • Cold-like symptoms such as runny nose, nasal congestion, and cough
  • Irritability and breathing problems in infants

Talk with your doctor about ways to ease your child’s symptoms.

Fifth Disease

Another viral illness, fifth disease is common in kids ages 5 to 15.

A child with sickle cell anemia or a weak immune system can become very ill from fifth disease. It can also be serious in pregnant women.


A few days later, a bright red rash appears, usually on the face, then spreads down the body. By the time the rash appears, the illness is no longer contagious.

It can take 1 to 3 weeks for the rash to go away. In some children, the rash may itch, and the joints may ache.

Hand, Foot, and Mouth Disease

This contagious viral illness usually is not serious.

Children under age 5 are most likely to catch it, through saliva, fluid from blisters and possibly viral shedding through stool.


A few days later, painful sores may develop in the back of the throat.  A skin rash – typically on the palms and soles, but can also occur on the trunk and diaper region. It usually clears up in 7 to 10 days without treatment.


Croup targets the windpipe and voice box. It is most often caused by viruses and lasts for a week or less.


  • Usually starts with a sudden onset of barky cough and stridor, which gets worse at night 
  • Runny nose
  • Fever
  • Other cold-like symptoms

Use a cool mist humidifier or run a hot shower, and sit with your child. If your child is having trouble breathing, having noisy breathing, or not eating or drinking well, call 911 or go to the emergency room. Steroids, cool mist and breathing treatments are sometimes given to decrease airway swelling.

Scarlet Fever

This bacterial infection is caused by group A strep.  (It was once a deadly disease, but now it is easily treatable.)


Sore throat

  • Scarlet-colored rash around the neck and face that may spread to the rest of the body.

If your child has a sore throat and rash, call the doctor. If the strep test is positive, then it is important to treat it with a round of antibiotics to prevent rare but serious complications.


This skin infection is most common in younger children. It starts when staph or strep bacteria gets in a cut, scratch, or bite. It can affect any area of the body but happens most often around the mouth, nose, and hands. Babies sometimes get the irritation in their diaper area.


  • Tiny blisters that burst. Fluid from the sores creates a crust that looks like a coat of honey.

Touching or scratching the sores, which can be itchy, spreads impetigo to other parts of the body and to other people. An antibiotic ointment, and sometimes an oral antibiotic, can treat it.

Kawasaki Disease

This childhood illness inflames blood vessels throughout the body. It is exceedingly rare, and the cause is unknown. Boys under age 5 of Asian or Pacific Island descent are most likely to get it. Most get well within weeks. But if it affects the arteries to the heart, it can cause serious, long term problems.


  • Fever that lasts 5 or more days
  • Red eyes 
  • Red lips or tongue and redness on the hands and feet
  • Rash
  • Swollen lymph node

There is no way to prevent this disease, but it is not contagious. Early treatment is key.

Reye’s Syndrome

This rare illness can come on suddenly. Children under age 15 who are getting over a viral illness like chickenpox or the flu are most likely to get it. It can be serious and cause damage to the liver and brain.


  • Vomiting
  • Lack of energy
  • Irritability or aggression


The best way to treat Reye's syndrome is to prevent it. It is strongly linked to aspirin, so never give your child or teen aspirin, especially for a viral illness. If you suspect your child has it, get medical help right away.

Whooping Cough (Pertussis)

Anyone can catch this bacterial infection of the lungs and breathing tubes, but infants are the most likely to get seriously ill from it.


  • Cold-like symptoms

A few days later, the cough gets worse, and a “whooping” sound may be heard as child gasps for air. Antibiotics can sometimes help by easing the symptoms, if treated early. Babies are often hospitalized so staff can monitor their breathing.

It is quite easy to catch. Your baby should start getting vaccines at 2 months old. Parents and older children need to get vaccinated to protect the baby. A woman should also get a pertussis shot while she is pregnant. Pertussis lasts five years and would still be effective during other pregnancies during that time.
