U10.9: Multisystem inflammatory syndrome associated with COVID-19, unspecified

COVID-19 is the abbreviation for coronavirus disease of 2019. This disease is caused by certain coronaviruses.

When you get infected by certain coronaviruses, you can have symptoms. But you may not have any symptoms despite being infected. In both cases, inflammation can occur in the body some time after infection. The inflammation can affect many different organs. For example, it can affect the skin, heart or gastrointestinal tract. The mucous membranes or the lungs can also become inflamed.

You may then feel very ill and weak. You might get skin rashes and fever, for example. You can also get bad stomach pains or problems with your heart.
