Children at risk – This is a life-threatening complication of COVID

It is not true that Covid-19 is not dangerous for children. Even children who have been almost asymptomatic with the coronavirus can develop what is known as Kawasaki syndrome, which, despite modern medical care, is fatal in about 1 percent of cases.

What is this disease?

Following the first wave of the new coronavirus epidemic, there has been a sharp increase in the number of cases of Kawasaki syndrome in several countries, including the United States, Italy, France, Britain and India. Egészsé

Symptoms of Kawasaki syndrome

To the best of our knowledge, Kawasaki syndrome is a group of symptoms that mainly affects children under the age of 5, with inflammation of the blood vessel walls, which has a variety of symptoms, including:

  • With a fever lasting for 1-2 weeks, flaming again and again, barely reacting to antipyretics,
  • mainly with rashes on the trunk,
  • with conjunctivitis,
  • with mucositis,
  • cervical lymph node enlargement,
  • with arthritis of varying severity, mainly in the large joints.
  • described as the watering and redness of the palms and soles in connection with the disease,
  • “raspberry tongue” has been reported,
  • gastrointestinal complaints and
  • aseptic meningitis (inflammation of the meninges).

The most serious complication of Kawasaki syndrome is the so-called coronary arteritis, which may be accompanied by inflammatory dilatation of the coronary arteries, heart failure, arrhythmia, myocarditis, endocarditis, thrombosis, or myocardial infarction.

Due to the complications, the mortality rate for Kawasaki syndrome is also around 1 percent with hospitalization.

First respiratory infection, then Kawasaki syndrome

Recent knowledge suggests that infection with various types of infection, including a new type of coronavirus (SARS-CoV-2), is behind Kawasaki syndrome. Although the specific link is not yet known, given the knowledge gained so far during the Covid-19 pandemic, it appears that Covid-19 also functions as a “trigger” for Kawasaki syndrome.

The data show that 42 percent of children with Kawasaki syndrome had flu-like symptoms in the previous 45 days. In 91 percent of children with Kawasaki syndrome, a test based on IgG detection was positive, that is, it has been shown that children have recently been infected with SARS-CoV-2, whether or not they have had any symptoms. All this confirms that the vast majority of the new types of coronavirus infection that have already taken place, rather than the current ones, are behind Kawasaki syndrome.

Kawasaki syndrome associated with SARS-CoV-2 may be more severe

It is noticeable that the age of children diagnosed with Kawasaki syndrome during the Covid-19 pandemic was higher than previously described in the literature: Kawasaki syndrome was confirmed from 6 months to 16 years after SARS-CoV-2 infection.

In addition, the incidence of severe cardiac complications was significantly higher than previously reported for Kawasaki syndrome following other respiratory infections. In 2020, Early heart problems have been reported in one-third of Kawasaki syndromes that may be associated with SARS-CoV-2 infection.

In summary: the new type of coronavirus is also a threat to children, although children with COVID-19 have a milder course and a better chance of recovery than adults. There is therefore a risk whether or not a child will be diagnosed with a new type of coronavirus infection. (It is an unfortunate fact that children who show no symptoms but are considered contact are not usually tested in everyday practice.)

What can a parent do?

In addition to trying to prevent Covid-19 in your child, you should be aware of the nature of Kawasaki syndrome complaints and seek medical attention immediately if they are suspected.
