Is it common to develop multisystem inflammatory syndrome (MIS) after recovering from COVID-19? While it is very rare, some people, mostly children, experience multisystem inflammatory syndrome (MIS) during or immediately after a COVID-19 infection. MIS is a condition where different body parts can become inflamed.
How does your immune system react after you recover from a viral infection?
After people recover from infection with a virus, the immune system retains a memory of it. Immune cells and proteins that circulate in the body can recognize and kill the pathogen if it’s encountered again, protecting against disease and reducing illness severity.

How long after being infected with Covid-19 can multisystem inflammatory syndrome in adults (MIS-A) occur? This new and serious syndrome, called multisystem inflammatory syndrome in adults (MIS-A), occurs in adults who were previously infected with the COVID-19 virus and many didn’t even know it.

What does higher viral load mean in the context of COVID-19? Viral load refers to the amount of virus that can be detected in an infected person. High viral loads are concerning because they can mean the person is more infectious.
How long do antibodies last in people who have mild COVID-19 cases?
A UCLA study shows that in people with mild cases of COVID-19, antibodies against SARS-CoV-2 — the virus that causes the disease — drop sharply over the first three months after infection, decreasing by roughly half every 36 days. If sustained at that rate, the antibodies would disappear within about a year.
