Question: Do all children that contract COVID-19 also develop MIS-C?

page_title: Clinical Questions about COVID-19: Questions and Answers
section_headers: COVID-19 Risk
What is multisystem inflammatory syndrome in children (MIS-C) and who is at risk?
section_content: CDC is investigating reports of multisystem inflammatory syndrome in children
(MIS-C) associated with COVID-19. Patients with MIS-C have presented with a
persistent fever and a variety of signs and symptoms including multiorgan
(e.g., cardiac, gastrointestinal, renal, hematologic, dermatologic,
neurologic) involvement and elevated inflammatory markers. CDC is
collaborating with domestic and international partners to better understand
this new syndrome, including how common it is and its risk factors, and to
begin tracking cases. For more information including a full case definition,
visit the CDC Health Alert
Network. For additional
clinical guidance, visit Information for Pediatric Healthcare
Providers.

Reviewer feedback on this answer:
Answer is only confirming investigations of children acquiring MIS-C but not what the criteria are for which children are likely to get it or any other risk factors. Perhaps the links will have more information but it would be impossible to know without clicking on them.
While this answer is relevant to the topic, it does not directly answer the question.

Answer passage (source: CDC):
page_title: For Parents: Multisystem Inflammatory Syndrome in Children (MIS-C) associated with COVID-19
section_headers: What we don’t know about MIS-C
section_content: CDC is still learning about MIS-C and how it affects children, so we don’t
know why some children have gotten sick with MIS-C and others have not. We
also do not know if children with certain health conditions are more likely to
get MIS-C. These are among the many questions CDC is working to try to
understand.
All CDC recommendations are based on the best data and science available at
the time, and we will update them as we learn more.

Reviewer feedback on this answer:
Answer may not be what the requester wants to hear but at least it is honest in that the CDC does not have enough information as to why some children get MIS-C and not others.
This answer does not relate or answer the question of whether all children with COVID-19 develop MIS-C.

How do you diagnose and report a potential case of multisystem inflammatory syndrome in children (MIS-C)?
section_content: Patients with MIS-C have presented with a persistent fever and a variety of
signs and symptoms including multiorgan (e.g., cardiac, gastrointestinal,
renal, hematologic, dermatologic, neurologic) involvement and elevated
inflammatory markers. Not all children will have the same symptoms. For
children who may have MIS-C, further evaluation for signs of this syndrome may
include (but are not limited to) chest radiograph, echocardiography, and blood
testing to evaluate for evidence of inflammation.
Healthcare providers who have cared or are caring for patients younger than 21
years of age meeting MIS-C criteria should report suspected cases to their
local, state, or territorial health department. After hour phone numbers for
health departments are available at the Council of State and Territorial
Epidemiologists website.external

Network. For guidance for
pediatric healthcare providers, visit Information for Pediatric Healthcare
Providers.

Reviewer feedback on this answer:
Answer only lets people know what should be done if there is a patient with MIS-C but nothing about whether children themselves are susceptible or what constitutes high risk for susceptibility.
This answer relates to the topic of MIS-C but does not relate to COVID-19 and its influence for children contracting it.
