[Progress in research on cytokine storm].

Infectious disease is a kind of disease that can be transmitted between humans and animals. Respiratory infectious diseases are more likely to cause outbreaks through droplet transmission. Coronavirus has repeatedly caused global public health events. Initial symptoms of the infected patients were mild, and the onset of the disease was hidden, but some patients suddenly get worse in a short time, and eventually died due to multiple organ failure. Studies have found that cytokine storms caused by patients' excessive immune response was one of the important causes of death in the infected patients.
