According to statistics, young people and children who test positive for coronavirus (Covid-19) generally only suffer from the disease mildly. However, some of them develop pediatric inflammatory multisystem syndrome (MIS-C) that can be serious, although so far it is not very clear what causes it and what the risk factors are.
The MIS-C causes severe inflammation in organs and tissues of the body, for example, the heart, lungs, blood vessels, kidneys, digestive system, brain, skin, or eyes.
The Centers for Disease Control and Prevention and the National Institutes of Health continue to work with medical specialists and researchers to learn more about risk factors for MIS-C, share data, and improve the diagnosis and treatment of the syndrome.
Usually this syndrome is found in children and young people, and very rarely in adults, although, if it happens it is also serious. It is known as multisystem inflammatory syndrome in adults (MIS-A). Some patients recovered from Covid-19 presented this syndrome and were unaware that they had it.
A test can diagnose the presence of MIS-A or MIS-C, or a study of antibodies to Covid-19 can help confirm an infection, according to the Mayoclinic.org site.
In children, MIS-C syndrome includes the following, although not all children manifest in the same way:
Fever that lasts 24 hours or longer Vomiting Diarrhea Stomach pain Skin rash Feeling unusually tired Fast heartbeat Rapid breathing Red eyes Redness or swelling of the lips and tongue. Redness or swelling of the hands or feet. Headache, dizziness, or lightheadedness. Enlarged lymph nodes
MIS-C Emergency Warning Signs
Severe stomach pain Difficulty breathing Blue lips or face New confusion Inability to wake up or stay awake
