WWL-TV's Eyewitness News reports on "an unusually high number of people suffering from auto-immune diseases in the Morgan City vicinity." The investigation reveals that the ailments common in the area - scleroderma, lupus, rheumatoid arthritis, and other tissue-transforming illnesses - might have been caused by environmental problems as well as genetic factors. Morgan City is an oil town with several industrial plants and five superfund waste sites, the program reports. Health officials have discovered a similar concentration of auto-immune diseases in Southern Boston as well. Experts are wary of linking the disease clusters to environmental factors only.
