Pediatric Multisystem Inflammatory Syndrome (MIS) Now Seen in Adults, Too
What is Multisystem Inflammatory Syndrome?
Multisystem Inflammatory Syndrome (MIS) is a rare, but very severe, complication associated with COVID-19 infection. The majority of cases have occurred among children and adolescents under 20 years old, with a median age of 10 years. The most common symptoms are persistent fever, abdominal pain or diarrhea, rash, and vomiting.
Can adults get MIS?
Recent reports from the CDC also show cases of MIS in adults, ages 21 to 50 years old. These cases exhibited similar symptoms and severe inflammation, and had a positive COVID-19 test within the past 12 weeks. Most patients with MIS required intensive care and had multiple organs impacted. As of November 2020, there were 27 known cases of MIS in adults.
How can I prevent MIS?
The CDC is still gathering information about MIS in adults. In the meantime, the best way to protect yourself from MIS is by continuing COVID-19 prevention strategies and receiving the vaccine when it becomes available to you. If you experience any of the symptoms of MIS, contact your medical provider immediately.
