In immunology, systemic inflammatory response syndrome (SIRS) is an inflammatory state affecting the whole body. [1] It is the body's response to an infectious or noninfectious insult . Although the definition of SIRS refers to it as an "inflammatory" response, it actually has pro- and anti-inflammatory components.
The symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves. [15] The symptoms of influenza are similar to those of a cold, although usually more severe and less likely to include a runny nose. [6] [16] There is no vaccine for the common cold. [3]
Invasive GBS infections in non-pregnant adults convey a rising hardship in most developed countries. Vaccination to prevent GBS infection could be a crucial approach to prevent GBS disease in adults. [130] [131] Toxic shock syndrome (TSS) is an acute multisystem life-threatening disease resulting in multiple organ failure. The severity of this ...
Norovirus cases are surging in the US, the CDC says. Here are the symptoms to look for, plus how long you're contagious for, per an infectious disease doctor.
The suppression of CD4 T cells by HIV (or by immunosuppressive drugs) causes a decrease in the body's normal response to certain infections. Not only does this make it more difficult to fight the infection, it may mean that a level of infection that would normally produce symptoms is instead undetected (subclinical infection).
The term inflammation is not a synonym for infection. Infection describes the interaction between the action of microbial invasion and the reaction of the body's inflammatory response—the two components are considered together in discussion of infection, and the word is used to imply a microbial invasive cause for the observed inflammatory ...
An autoimmune disease is a condition arising from an abnormal immune response to a normal body part. [5] There are at least 80 types of autoimmune diseases. [5] Nearly any body part can be involved. Common symptoms include low-grade fever and feeling tired. [5] Often symptoms come and go. [5]
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with body temperature exceeding the normal range due to an increase in the body's temperature set point in the hypothalamus.
