Welder's Anthrax case

[Owen Lucas]

Here's a weird case I read about in Ars Technica about how welders might be predisposed to contracting anthrax. This guy was lucky because a smart doctor caught it in time, but 6 others weren't.

• The Exposure Route: The patient likely inhaled Bacillus anthracis spores stirred up from ancient soil during his work as a welder, as the bacteria can survive for decades in the ground until disturbed by construction or industrial activity.
  
  
• High Iron Levels: The review notes that iron is "essential for virtually all living cells," and in this case, the high levels of iron in the welder's system (likely from inhaling iron-rich welding fumes) acted as a "super-fuel" that allowed the anthrax to replicate at a terrifying speed.
  
  
• Chemical and Fume Damage: Chronic exposure to welding chemicals and metal fumes likely compromised the protective lining of his lungs, creating microscopic "doorways" that allowed the inhaled spores to bypass his natural defenses and enter his bloodstream.
  
  
• Lack of Ventilation: Working in poorly ventilated or confined spaces concentrated the concentration of both toxic metal fumes and airborne spores, overwhelming his immune system’s ability to clear the pathogens before they could germinate.
  
  
• Isolated Conditions: Because the patient was working in a remote, rural area where anthrax occurs naturally in soil, the "isolated conditions" meant he was in direct contact with high-risk dust that city-dwellers rarely encounter.
  
  
• The Critical Diagnosis: Doctors "caught" the infection when a sharp-eyed lab technician noticed a specific square-ended, "boxcar" shape of the bacteria in a blood culture, a classic signature of B. anthracis that is rarely seen in modern medicine.
  
  
• The Rare Antidote: Because anthrax is so rare and potentially a biothreat, the hospital had to source a specific antitoxin (raxibacumab) from the Strategic National Stockpile, a federal medicine reserve managed by the CDC.

All sounds plausible, but being that the "welder" is only 18, hardly likely that he has any lung damage from welding fumes to the extent that he is more vulnerable to the disease than any other healthy 18 year old IMHO.

He wasn't a "vaper" unless it was welding fumes. So important to wear PPE. Unsure if he is now vulnerable to more diseases after this experience. I think there is a correlation with Alzheimer's for welders as well, maybe via the same route?
