When a person becomes infected with the COVID virus, cytokines are created from cells in order to combat the disease. The problem is that these same cytokines quickly attack and inhibit other healthy cells around them.
Even after COVID-19 has been cleared, the body remains inflamed and symptoms arise. A study showed that COVID Long Haulers can cause over 200 different symptoms which have been linked to cytokines. As doctors now seem to understand what is causing Long Haulers they can begin to focus on treatments that can help.
