A 31-year-old man who helped to repair homes in Galveston, Texas after flooding caused by Hurricane Harvey was recently diagnosed with flesh-eating bacteria and died on October 16th after being admitted to a hospital on October 10th, according to a statement released by health officials in Galveston on Monday.
He is the second person to die from flesh-eating bacteria since Hurricane Harvey struck the Gulf Coast. Two weeks ago, a 77 year old woman died after a fall inside her flooded home in which she cut her arm and subsequently contracted the flesh-eating bacteria.
When the man initially presented to the hospital on October 10th, officials described an infected wound affecting the upper portion of his left arm.
The aggressive and deadly soft tissue infection is formally referre... . It’s a rare infection under normal circumstances, but if promptly recognized, diagnosed and treated with the appropriate antibiotics and surgery to remove dead or dying tissue, the majority of patients recover without any serious consequences.
Necrotizing fasciitis, or “nec fasc”, is most commonly caused by Gr... , but a mixed infection with anaerobic bacteria including Clostridium may also develop, leading to what is commonly known as gas gangrene. Necrotizing fasciitis causes pain out of proportion in the affected area, relative to the degree of injury.
A cut, scrape, puncture or any break in the skin may serve as a portal of entry for the dangerous bacteria, which then leads to destruction of blood vessels, fat, nerves and a white fibrous covering of the muscle known as the fascia. The infection then proceeds to enter the muscle, compromising blood flow and leading to death of the tissue.
Its important to realize that bacteria don’t actually digest the tissue, but instead produce a deadly toxin that is responsible for the extensive tissue damage.
As the bacteria enter the bloodstream, fever, chills and vomiting may rapidly develop, leading to a dangerous condition known as sepsis which is characterized by low blood pressure, rapid and difficult breathing and confusion.
Early warning signs include severe pain and tenderness in the infec... and blue to purple skin discoloration, with darkened tissue in the later stages. The presence of gas or air in the soft tissue known as “crepitus” produces a crackling sound or crunching sensation if the area of skin is palpated. An abscess containing pus may also form as the infection becomes more organized.
Necrotizing fasciitis is a surgical emergency. Aggressive fluid resuscitation along with broad spectrum antibiotics must be started promptly with emergent preparation for surgery to remove or debride the affected area in order to contain the infection.
Persons with diabetes, chronic kidney disease and cancer who are receiving chemotherapy are most at risk for complications, due to poor blood supply to skin, muscle and soft tissue from having such chronic conditions.
Flood waters harboring bacteria (from sewage), along with dirty surfaces or debris contacting the victim’s initial cut or injury, likely led to the onset of this aggressive and deadly infection. As a general rule, it’s best to keep all cuts or blisters covered with a dry gauze and waterproof type dressing if there is any potential to come in contact with floodwater or dirty surfaces or debris.
The CDC describes about 700-1,110 cases annually in the U.S., the result of an active surveillance and reporting network that is set up to monitor such aggressive infections.
Cases of typhoid and cholera, invasive and aggressive diarrheal illnesses typically associated with floods in developing countries, never materialized after the hurricane, according to data from the CDC. In addition, cases of tetanus, which can develop from heavily contaminated wounds after soil exposure, have generally not been a concern with such flooding in the U.S., as supported by data from the CDC.
“Necrotizing fasciitis is caused by strep group A (flesh-eating bacteria) or anaerobic bacteria which thrive in areas without oxygen,” said Debra Spicehandler, MD, Co-Chief of Infectious Diseases, Northern Westchester Hospital. ”Antibiotics are important but swift surgical debridement is necessary. The cases caused by strep release a toxin which can also cause systemic effects and organ failure leading to mortality.”
