Multisymptom inflammatory syndrome in adults (MIS-A) is a group of symptoms that develops as a complication of coronavirus disease 2019 (COVID-19). Inflammation develops in areas such as your heart, digestive system, skin, or brain. MIS-A may develop days or weeks after you were infected with the virus that causes COVID-19. You can develop MIS-A even if you did not know you were infected. MIS-A is a serious health problem that needs immediate care.
DISCHARGE INSTRUCTIONS:
Call your local emergency number (911 in the US) or have someone call if:
- You have trouble breathing.
- You have severe chest pain.
- You are confused.
- You cannot be woken, or you have trouble staying awake during the day.
Seek care immediately if:
- Your lips or nails are pale or look blue.
- You have severe pain in your stomach.
Call your doctor if:
- You have new or worsening symptoms.
- You have questions or concerns about your condition or care.
Self-care:
- Rest as needed. You may feel tired or have less energy for a while. Your healthcare provider will tell you when it is okay to drive and return to work or your other daily activities. Start slowly and do more as your energy improves.
- Drink liquids as directed. Liquids help prevent dehydration. Your healthcare provider will tell you how much liquid to drink each day and which liquids are best for you.
- Help prevent COVID-19. You may be able to pass the virus to others or become infected again. You may need to isolate for a few weeks. Wear a face covering (mask) when you are within 6 feet (2 meters) of anyone. Wash your hands often throughout the day. Cover your mouth and nose when you sneeze and cough, or use the bend of your arm. Get a COVID-19 vaccine. This is a shot given in 1 or 2 doses to prevent infection from the virus that causes COVID-19. Your provider can give you information on these and other ways to prevent COVID-19.
