Shock due to severe infection is referred to as what?

Septic shock refers to the condition where the body experiences a severe infection that leads to a systemic inflammatory response. This condition is characterized by the presence of bacteria or their toxins in the bloodstream, which causes a significant drop in blood pressure and can lead to organ failure. The immune system's response to the infection can cause widespread inflammation, leading to vascular dilation and increased permeability of blood vessels, contributing to the shock state.

This condition often develops in patients with severe infections, such as pneumonia, urinary tract infections, or abdominal infections, particularly when they are not promptly treated. In the context of the other options,

anaphylactic shock is an acute allergic reaction, neurogenic shock is caused by injury to the spinal cord affecting the nervous system's ability to control blood vessel tone, and hypovolemic shock is associated with a significant loss of blood or fluids.

Septic shock specifically relates to infection, making it the most accurate answer in the context of the question.
