Sonia Gandhi undergoing treatment for systemic infection: The body part it affects

A few days ago, senior Congress leader Sonia Gandhi was admitted to New Delhi's Sir Ganga Ram Hospital after she developed a fever. Today, her doctors said she is improving steadily and is expected to be discharged from the hospital soon. According to PTI, the 79-year-old is undergoing treatment for systemic infection, and doctors are closely monitoring her condition, though she is stable. A systemic infection affects the whole body rather than a single organ or body part. It can be a serious medical emergency requiring immediate treatment, according to the EU Clinical Trials Information Network. In patients affected by this condition, the infection reaches the bloodstream, triggering life-threatening complications. It can affect multiple tissues and organs in our body and can even lead to organ failure. 

Systemic infection's complications
Systemic infections can cause sepsis, a medical emergency due to our body's overwhelming response to infection. At times, instead of fighting infections, our immune system begins damaging our organs and tissues, resulting in body-wide inflammation. It can also affect our blood-clotting system, reducing blood flow to various organs. 

What causes systemic infections and sepsis
a) Bacterial infections
b) Viral, fungal and parasitic infections
Who are at risk?
a) Those above 65 years of age
b) Patients with a weak immune system
c) Those with chronic lung-kidney diseases, obesity, cancer or diabetes
d) Those with severe injuries, wounds or burns
e) Pregnant people
f) Those on breathing, IV tubes or catheters
