Why everyone needs to know about Kawasaki disease

January 26th, 2015 marks the 5th annual Kawasaki Disease Awareness Day.  I know many parents of KD survivors (myself included) and survivors themselves who are KD advocates and raise awareness on a daily basis.  I am sure there are people that wonder why we are so passionate about this cause, and given that it is considered rare, why it is such a big deal.  These are the reasons why everyone needs to know about Kawasaki disease:

1. It is often misdiagnosed.  Many of the symptoms associated with Kawasaki disease are also associated with numerous other childhood illnesses, making it difficult for doctors to determine the true cause of the symptoms.  To complicate matters even further, the symptoms may not show up at the same time (as in Isaiah's case) or many of the symptoms may not show up at all (incomplete KD).  Currently, there is no diagnostic test for Kawasaki disease.  It is typically diagnosed using a combination of clinical features, blood work (looking for elevated levels of certain components) and echocardiography.  Unfortunately, many children are misdiagnosed and sent home before these tests can even be run.  

(For more information on why KD is so commonly misdiagnosed, including links to the supporting scientific articles, please visit this great blog post by a fellow KD mom:

2. There is a highly effective treatment, but there is a small window of opportunity for it to be effective.  Although it has not been determined what causes Kawasaki disease, the good news is that a highly effective treatment is available.  Treatment with intravenous immunoglobulin (IVIG) typically "relieves acute inflammation and has been shown to reduce the rate of coronary aneurysms from greater than 25% in untreated patients to 1-5% in treated patients. Maximal benefits are seen when IVIG is given within the first 10 days of the illness." (According to Medscape.)  This means that if a child is diagnosed in a timely manner and administered IVIG within the first 10 days of having KD, their chances of developing coronary complications is greatly reduced.  Kawasaki disease can resolve on its own, without IVIG treatment, but the risk of the child developing coronary aneurysms is greater.  This means that timely diagnosis is very important!

3. It can cause permanent heart damage.  Kawasaki disease causes inflammation in small to medium-sized arteries, but the inflammation is most pronounced in the coronary arteries.  The coronary arteries are the arteries that supply blood to your heart muscles, so that it can contract and pump blood throughout your body.  In most cases, the inflammation in the arteries resolves over time, as the child recovers from KD.  However, in some cases the inflammation can cause permanent coronary aneurysms, which are areas where the artery wall balloons or bulges out.  This ballooning of the artery causes the blood to swirl in those areas and increases the risk of formation of blood clots.  If a blood clot develops it can result in blockage of the artery and a heart attack.  Children that develop permanent aneurysms face a lifetime of blood thinning medications (with the associated activity restrictions), frequent medical exams, invasive testing, the always looming possibility of surgical intervention and constant uncertainty about their health. Tragically, I know of children that have passed away as a result of the aneurysms caused by Kawasaki disease, because they were never diagnosed or diagnosed too late.

The bottom line is that KD can result in serious heart damage and even death, but thankfully a treatment does exist to reduce the risks of this happening. However, the correct diagnosis needs to be made before this treatment can be given.  In order to receive the correct diagnosis, you need to know the symptoms.

The common symptoms of Kawasaki disease are:

Fever that lasts for five or more days
Rash, often worse in the groin area
Red bloodshot eyes, without drainage or crusting
Bright red, swollen, cracked lips, "strawberry" tongue, which appears with shiny bright red spots after the top coating sloughs off
Swollen hands and feet and redness of the palms and soles of the feet
Swollen lymph nodes in the neck

It is important to remember that all of these symptoms may not be present or may not be present at the same time.  If you child has a prolonged fever and two or more of these symptoms, be sure to ask your doctor if it could be Kawasaki disease.

Many little hearts can be saved by simply educating yourself and others about Kawasaki disease.  Kawasaki disease is highly treatable and just knowing the symptoms and voicing your concerns could save your child from living with acquired heart disease for the rest of their life. By sharing this information with others you may even save a child's life.  In this case, knowledge really is power.


  1. I like your blog
    I would be glad if u could comment on my blog too. Since my blog is new just 21 days old. I have little experience.

  4. Very well written and informative article, thank you :-)


  5. Yeah it's good article and thank you sharing post, Kawasaki is the name of a Japanese scientist who discovered a disease called KAWASAKI’S DISEASE that was very prevalent in Japan.
    This disease occurs,still trying to figure out the cause of this disease and two main theories that have been put put forth are either it could occur after some other infectious disease or some immune system abnormality Kawasaki disease typically presents as fever, rash all over the body, pain in neck, red eye (conjunctivitis), strawberry coloured tongue, red lips, enlarged neck glands and typically even pain in joints.

    I hope this helpful for you.

Quick update: second bout of Kawasaki disease

A new post is long overdue and it saddens me that this post was created in order to share news of Isaiah's second battle with Kawasaki disease.  Coincidentally, I have been working on a post entitled "Gratitude," which is much more uplifting. Despite the recent turn of events I plan on completing that  post, so it will be coming soon.

I will not be going into too much detail right now. I just wanted to post a quick update for those of you who have been concerned about Isaiah this past week.

Symptoms Isaiah started off with a low grade fever last week, which we assumed was just the beginning of a cold or flu. We kept him home from school, but he seemed to have lots of energy during the day and was acting very much like his normal self. He did complain of a pain in the middle of his neck, which we thought may just be a sore throat.   I took him to his pediatrician on Wednesday, but he did not note any swollen lymph nodes of redness of his throat.  He took a swab for strep …

To Whom It May Concern

To Whom It May Concern,
Hello old high school acquaintance on Facebook, who usually scrolls past me on their newsfeed.Greetings to the mom from school who knows my son has a medical condition, but is too afraid to ask me about it.Dear second cousin Judith, whose mom told her that my son was really sick, “but thank God he’s okay now.”To my neighbour up the street, to the kindergarten teacher at the school, to the mom sitting beside me at the doctor’s office and to the dad sitting beside me at swimming lessons.

This letter is written to anyone that has a child in their life that they care about.
You may have heard of something called Kawasaki disease…but probably not.Contrary to the name, it has nothing to do with motorcycles.In short, Kawasaki disease (KD) is the leading cause of acquired heart disease in children in developed countries.You may be thinking, “Acquired heart disease in children?What does that even mean?I thought kids with heart problems are born with it?”Not all cases of …

What it Means to be a "KD Parent"

In the past I have often referred to our "new normal" -- the way in which we now live our lives, since Isaiah was diagnosed with coronary aneurysms.  Over time, this "new normal" has just become our normal.  Isaiah's scheduled medications are a daily reminder of his condition and Kawasaki disease seems to be ever present in my mind, but its effects have slowly faded to the background and just become part of the fabric of our lives.  I am often asked, "How is Isaiah doing?" and find myself automatically answering with a standard, "Great.  Everything is stable."  I do not feel it necessary to go into detail about Isaiah's latest test results or the health effects we deal with as a result of his multiple blood thinning medications.  In fact, I have become so effective at "glazing over" these details and get caught up in dealing with the chaos of every day life, that sometimes I actually forget what we are truly living with....unt…
