A total of 119 children were hospitalized by the end of 2021 with MISC syndrome, according to a Greek study. These children had a median age of 8 years, said the Professor of Pediatric Infectious Diseases and member of the Committee of Experts Vana Papaevangelou, in today’s briefing.
As he said the syndrome appears 3-6 weeks after the initial infection, regardless of the severity of the disease. Children usually present with high fever, gastrointestinal disorders and rash, and a significant percentage of them developed myocarditis and other heart complications.
Also, 2 out of 10 children had to be admitted to the ICU.
Ms. Papaevangelou stressed that we are expected to see new cases of MISC syndrome.
A recent CDC study showed that vaccinating children with 2 doses reduced the chance of developing MISC by 91%.
At the same time, it showed that children who developed severe MISC were unvaccinated.
For myocarditis from the vaccine, mainly in boys, the professor said that data from the CDC show that 90 days after infection, 99% of children showed significant improvement, while 81% had a complete cure.
Therefore, it is a mild and transient complication.
Regarding the Omicron mutation, Ms. Papaevangelou said that a recent study in the general population confirmed that the previous coronavirus disease did not protect against the Omicron.
At the same time, another study from Sweden showed that the risk of serious disease was significantly reduced due to the spread of Omicron.
According to the same study, the vaccine provides effective protection against Omicron.
For unvaccinated people over the age of 64 and men over the age of 45 with underlying diseases, there is a high risk of serious illness whether they catch Omicron or Delta.
Therefore, for older unvaccinated people, Omicron will not be a simple cold, he stressed.
In general, the coronavirus in the country continues to have a steady course, with 1.5% of the population being active cases.
There is also a gradual de-escalation in ICUs.
