In the latest edition of the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report, released January 1, researchers confirmed a ninth known case of so-called “welder’s anthrax,” a rare but serious occupational illness.
According to the report, an 18-year-old male welder in Louisiana was hospitalized in September 2024 after suffering from a severe cough that persisted for about a week. Doctors initially diagnosed the patient with pneumonia complicated by respiratory failure. Further investigation, however, prompted concerns about anthrax exposure.
State and federal health officials coordinated testing and treatment, and the patient ultimately received anthrax antitoxin along with multiple antibiotics. The aggressive treatment proved successful, and the welder recovered, according to the CDC.
“Welder’s anthrax” is an uncommon form of anthrax infection believed to be associated with exposure to welding fumes and dust, particularly in confined or poorly ventilated spaces. The CDC reports that all known cases to date have occurred in Louisiana and Texas. Of the nine confirmed cases, six have been fatal.
In light of the findings, the CDC is urging employers and workers in the welding industry to strengthen safety measures. Recommendations include improving ventilation, reducing exposure to welding fumes and dust, and enhancing protective protocols when welding in enclosed spaces.
Health officials emphasize that while the condition is rare, early recognition and treatment are critical to survival.
