A cytokine storm is an overreaction of the body’s immune system.
“In some people with COVID-19, the immune system releases immune messengers, called cytokines, into the bloodstream out of proportion to the threat or long after the virus is no longer a threat,” explains Harvard Health.
When this happens, the immune system attacks the body’s own tissues, potentially causing significant harm.
“A cytokine storm triggers an exaggerated inflammatory response that may damage the liver, blood vessels, kidneys, and lungs, and increase formation of blood clots throughout the body,” says Harvard Health.
