What is Necrotising fasciitis?

About Necrotising fasciitis:

• Necrotizing fasciitis, also known as flesh-eating disease, is a rare and life-threatening bacterial infection that affects the tissue under the skin called fascia. 
• "Necrotizing" means causing tissue death, and "fasciitis" refers to fascia inflammation, which is tissue under the skin. 
• It includes two types:

• Type I, or polymicrobial: This type happens when more than one bacteria, usually a mix of aerobic and anaerobic bacteria, causes the infection.
• Type II, or monomicrobial: The monomicrobial form is typically caused by one bacteria, group A streptococcus or Staphylococcus aureus bacteria.

• The infection may get into the body through:

• cuts and scratches
• burns and scalds
• insect bites
• surgery
• injecting drugs

• It is a form of necrotizing soft tissue infection (NSTI). These life-threatening infections affect the skin, muscles, and soft tissue and cause patches of tissue to die.
• Necrotising fasciitis infection typically travels along the fascial plane, which has a poor blood supply, leaving the overlying tissues initially unaffected, potentially delaying diagnosis and surgical intervention.
• It spreads quickly and aggressively in an infected person, causes tissue death at the infection site, and can be deadly if not treated right away.
• Symptoms: 

• Early symptoms of this condition include signs and symptoms that resemble those of the flu.
• Later signs and symptoms include Reddened and/or discolored skin, Swelling of affected tissues, Unstable blood flow, Blisters filled with bloody or yellowish fluid, Tissue death (necrosis), Low blood pressure, Sepsis, etc.

• Treatment: 

• Currently, there isn’t a vaccine to prevent necrotizing fasciitis.
• It’s treated with antibiotics and surgery to remove damaged tissue.
